Complete Question
An L-C circuit has an inductance of 0.350 H and a capacitance of 0.290 nF . During the current oscillations, the maximum current in the inductor is 2.00 A .
What is the maximum energy [tex]E_{max}[/tex] stored in the capacitor at any time during the current oscillations?
Express your answer in joules.
Answer:
The value is [tex]E_{max} = 0.7 J [/tex]
Explanation:
From the question we are told that
The inductance is [tex]L = 0.350 \ H[/tex]
The capacitance is [tex]C = 0.290 \ nF = 0.290 *10^{-9 } \ F[/tex]
The current is [tex]I = 2 \ A[/tex]
Generally the maximum energy is mathematically represented as
[tex]E_{max} = \frac{1}{2} * L * I^2[/tex]
=> [tex]E_{max} = \frac{1}{2} * 0.350 * 2^2[/tex]
=> [tex]E_{max} = 0.7 J [/tex]
An astronaut, whose mass on the surface of the Earth is m, orbits the Earth in the space shuttle at an altitude of 450 km. What is her mass while orbiting in the space shuttle?
a. 0.125 m
b. 0.50 m
c. 0.75 m
d. m
Answer:
d. m
Explanation:
Assuming that the shuttle orbits at a low speed compared with the speed of light, the mass must be the same.This is due to the mass is a property of bodies which is the same at any point in the universe, it doesn't depend of the force applied to it or any other thing, as weight does, provided no relativistic effects take place.So, the right answer is d.This question involves the concepts of mass, Law of conservation of mass, and altitude.
The mass of the astronaut orbiting in the space shuttle is "d. m".
The mass of an object is defined as the quantity of matter contained inside a body. According to the law of conservation of mass, the mass of a body remains constant everywhere in the universe.
The quantity that changes with the change in location, is weight. The change in weight is caused by the change in acceleration due to gravity, which varies from planet to planet and also varies with altitude.
Thus, the mass of the astronaut will remain constant.

Street light in many communities are sodium vapor lamps. These lamps visually have an orange-yellow tint. The visible emission spectrum for sodium shows that two prominent bands are detected within the visible color change. These light waves are both yellow and have wavelengths of about 590nm. This explains why the light produced from sodium vapor lamps would appear yellow and not white. in comparison, mercury vapor lamps produce a blue-colored light due to intense light emission from the mercury atoms that have a wavelength of about 434nm. Without any calculation, which element would you expect to produce higher energy photons in the visible part of spectrum?
Answer:
Mercury light
Explanation:
The energy of a photon of light is inversely proportional to it's wavelength.
Therefore, as the wavelength increases, the energy decreases likewise.
This implies that the Mercury light having a lesser wavelength will possess more energy.

½ mv² = mgh + Fd
½ mv² = mgh + mgμd
½ v² = gh + gμd
½ v² − gh = gμd
d = (½ v² − gh) / (gμ)
d = (½ (7.5 m/s)² − (10 m/s²) (2.1 m)) / ((10 m/s²) (0.35))
d = 2.0 m
Find the work done by a 75.0 kg person in climbing a 2.50 m flight of stairs at a constant speed.
Answer:
1,839.375 Joules
Explanation:
Work is said to be done is the force applied to an object cause the object to move through a distance.
Workdone = Force * Distance
Workdone = mass * acceleration due to gravity * distance
Given
Mass = 75.0kg
acceleration due to gravity = 9.81m/s²
distance = 2.50m
Substitute the given parameters into the formula:
Workdone = 75.0*9.81*2.50
Workdone = 1,839.375Joules
Hence the workdone is 1,839.375 Joules

The question is incomplete. Here is the complete question.
7) A standard backpack is approximately 30cm x 30cm x 40cm. Suppose you find a hoard of pure gold (density = 19.3 g/cm³) while treasure hunting in the wilderness. How much mass would your backpack hold if you filled it with gold?
8) 50 pounds is equal to 22,700 grams. How many pounds does this backpack full of gold weigh? Would you be able to carry out that backpack filled with gold?
Answer: 7) m = 694,800g
8) It wieghts 1530.4 lbf
Explanation:
7) Volume of the backpack will be
V = 30 x 30 x 40
V = 36000 cm³
According to density of gold, each cm³ corresponds to 19.3g, then:
m = 19.3[tex]\frac{g}{cm^{3}}[/tex] * 36000cm³
m = 694800g
If I filled it with gold, the backpack will hold 694800g or 694.8kg.
8) 50 pounds is equal to 22700g. Then:
50 pound = 22700g
W = 694800g
W = [tex]\frac{694800.50}{22700}[/tex]
W = 1530.4 lbf
The backpack, in pounds, will weigh 1530.4lbf, which is very heavy to be supported by a human body.

Answer:
Option iv
Explanation:
The acceleration due to gravity (g) of the earth is constant (i.e 9.81 ms¯²). As long as the stone remains within the earth, the acceleration due to gravity experienced by the stone will be 9.81 ms¯².
The maximum height reached by an object is the height where the object no longer have velocity to move further hence it begins to fall back. At this point (i.e at the maximum height), the velocity of the object is zero.
Summary:
At maximum height:
Acceleration due to gravity of the stone = 9.81 ms¯²
Velocity = 0
Thus, option iv gives the correct answer.

A large semi-truck, with mass 31x crashes into a small sedan with mass x . If the semi-truck exerts a force F on the sedan, what force will the sedan exert on the semi-truck
Answer:
Force Exerted by Sedan on Truck = - F
Explanation:
This question can easily be solved by using Newton's Third Law of Motion. Newton's Third Law of Motion clearly states that for every action force there exists an equal in magnitude reaction force. However, the direction of the reaction force is opposite to the direction of the action force. Mathematically,
Action Force = - Reaction Force
Hence, we have here:
Force Exerted by Semi Truck on Sedan = F
So, from Newton's Third Law of motion:
Force Exerted by Sedan on Truck = - Force Exerted by Semi Truck on Sedan
Force Exerted by Sedan on Truck = - F

Brownian motion is observed when looking at smoke particles in a microscope.What causes the smoke particles to move at random?
Answer:
Explanation:
Brownian motion is evidence that air molecules move in random directions, with random speeds (and hence kinetic energy). When these air molecules knock into the smoke particles, they cause the smoke particles to move in random motions.
Why can't we see the air molecules themselves? That's because the air molecules are invisible, even with microscopes

A) What is the magnitude of the particle's acceleration produced by a uniform magnetic field B = (1.63T)i^+(0.980T)j^?
B) What is the direction of the particles acceleration? Please show steps so I can follow.
Answer:
a = -0.33 m/s² k^
Direction: negative
Explanation:
From Newton's law of motion, we know that;
F = ma
Now, from magnetic fields, we know that;. F = qVB
Thus;
ma = qVB
Where;
m is mass
a is acceleration
q is charge
V is velocity
B is magnetic field
We are given;
m = 1.81 × 10^(−3) kg
q = 1.22 × 10 ^(−8) C
V = (3.00 × 10⁴ m/s) ȷ^.
B = (1.63T) ı^ + (0.980T) ȷ^
Thus, since we are looking for acceleration, from, ma = qVB; let's make a the subject;
a = qVB/m
a = [(1.22 × 10 ^(−8)) × (3.00 × 10⁴)ȷ^ × ((1.63T) ı^ + (0.980T) ȷ^)]/(1.81 × 10^(−3))
From vector multiplication, ȷ^ × ȷ^ = 0 and ȷ^ × i^ = -k^
Thus;
a = -0.33 m/s² k^

6.7.5. While you sleep, your body is using energy at a rate of 77 W. How many food calories are used during an eight hour period
Answer:
6.38×10¯⁴ Calorie.
Explanation:
The following data were obtained from the question:
Power (P) = 77 W
Time (t) = 8 h
Energy (E) =.?
Next, we shall convert 8 hours to seconds. This can be obtained as follow:
1 h = 3600 s
Therefore,
8 h = 8 h × 3600 s / 1h
8 h = 28800 s
Next, we shall determine the energy. This can be obtained as follow:
Power (P) = 77 W
Time (t) = 28800 s
Energy (E) =.?
Energy (E) = Power (P) / time (t)
E = P/t
E = 77 /28800
E = 2.67×10¯³ J
Finally, we shall convert 2.67×10¯³ J to calorie. This can be obtained as follow:
4.184 J = 1 calorie
Therefore,
2.67×10¯³ J = 2.67×10¯³ J × 1 Cal / 4.184 J
2.67×10¯³ J = 6.38×10¯⁴ Calorie.
Therefore, 6.38×10¯⁴ Calorie of food is used during the 8 hours period.
A 1000kg boat is being towed by a rope that makes an angle of 20 degrees with respect to the x-axis. The boat accelerates horizontally from rest to 10 m/s in 5.0 seconds. During this time, a total drag force of 500N acts on the boat from the water. What is the tension in the rope during this time?
Answer:
Explanation:
acceleration of the boat a = (10 - 0) / 5 = 2 m /s²
Let tension in the rope be T
Horizontal component = T cos20
force acting on boat = T cos20 - 500
applying newton's law
T cos20 - 500 = mass x acceleration
T cos20 - 500 = 1000 x 2 = 2000
T cos20 = 2500 N .
T x .94 = 2500
T = 2660 N .
The masses of the Earth and Moon are 5.98×1024kg and 7.35×1022kg respectively, and their centers are separated by 3.84×108m.
At what distance from the center of the Earth is the CM of the Earth-Moon system located?
What can you say about the motion of the Earth-Moon system about the Sun, and of the Earth and Moon separately about the Sun?
A) The Earth-Moon CM follows the orbit around the Sun. Earth and Moon rotate around their CM. The radius of rotation of Earth around the CM is much greater than radius of rotation of Moon around the CM.
B) The Earth and Moon follow separate circular orbits around the Sun.
C) The Earth-Moon CM follows the orbit around the Sun. Earth and Moon rotate around their CM. The radius of rotation of Moon around the CM is much greater than radius of rotation of Earth around the CM.
Answer:
C) The Earth-Moon CM follows the orbit around the Sun. Earth and Moon rotate around their CM. The radius of rotation of Moon around the CM is much greater than radius of rotation of Earth around the CM.
Explanation:
At first we assume that both Earth and Moon can be treated as particles, the center of mass of the Earth-Moon system is obtained by using this formula:
[tex]r_{CM} = \frac{r_{E}\cdot m_{E}+r_{M}\cdot m_{M}}{m_{E}+m_{M}}[/tex] (Eq. 1)
Where:
[tex]r_{E}[/tex] - Location of the center of the Earth, measured in kilometers.
[tex]r_{M}[/tex] - Location of the Moon, measured in kilometers.
[tex]r_{CM}[/tex] - Location of the center of mass, measured in kilometers.
[tex]m_{E}[/tex] - Mass of the Earth, measured in kilograms.
[tex]m_{M}[/tex] - Mass of the Moon, measured in kilograms.
If we know that [tex]r_{E} = 0\,km[/tex], [tex]r_{M} = 3.84\times 10^{8}\,m[/tex], [tex]m_{E} = 5.98\times 10^{24}\,kg[/tex] and [tex]m_{M} = 7.35\times 10^{22}\,kg[/tex], the location of the center of mass respect to the Earth is:
[tex]r_{CM} = \frac{(0\,km)\cdot (5.98\times 10^{22}\,kg)+(3.84\times 10^{8}\,m)\cdot (7.35\times 10^{22}\,kg)}{5.98\times 10^{24}\,kg+7.35\times 10^{22}\,kg}[/tex]
[tex]r_{CM} = 4.662\times 10^{6}\,m[/tex]
The Earth has a radius of [tex]6.371\times 10^{6}[/tex] meters, we notice that center of mass in located inside the Earth and the radius of rotation of the Earth around the center of mass is much greater than the radius of rotation of the Moon around the center of mass. That center of mass follows an orbit around the sun.
In consequence, correct answer is C.
The distance from the center of the Earth is the Center of Mass of the Earth-Moon system located is 4.662×10⁶ m.
What is center of mass?The center of mass of a object or for a system of object is the point, where the center of distribution of mass in space. The center of mass for the two bodies can be given as,
It can be given as,
[tex]x_{cm}=\dfrac{m_1x_1+m_2x_2}{m_1+m_2}[/tex]
Here, (m) represents the mass and (x) represents the distance.
The masses of the Earth and Moon are 5.98×1024kg and 7.35×1022kg respectively,The centers of the Moon and Earth are separated by 3.84×108m.
Thus the center of mass with respect to Earth using the above formula can be given as,
[tex]x=\dfrac{(5.98\times10^{22})(0)+7.25\times10^{22}(3.84\times10^8)}{5.98\times10^{22}+7.25\times10^{22}}\\x=4.662\times 10^6\rm m[/tex]
The motion of the Earth-Moon system about the Sun is less than the Earth and Moon separately about the Sun is, due to the center of rotation of the earth.
Thus, the Earth-Moon CM follows the orbit around the Sun. Earth and Moon rotate around their CM. The radius of rotation of Moon around the CM is much greater than the radius of rotation of Earth around the CM. Option C is correct.
Thus, the distance from the center of the Earth is the Center of Mass of the Earth-Moon system located is 4.662×10⁶ m.
