Find the equivalent resistance of this circuit.
Step-by-step explanation :
Here we just need to see the resistors which are connected in series combination. (Remember that you need not to use the potential difference in this question because we aren't asked to calculate the current).
As we know that,
Rs = R1 + R2 ... Rn>> Rs = 50 + 100
>> Rs = 150Ω
Therefore,
Resistance in series combination is of 150Ω.Forces (select all that apply) *
1:make objects move
2:have the unit of Newtons (N)
3:can be positive or negative in value
4:can go in any direction (North South East West)
Explanation:
1, 2,3, and 4 is correct.
Forces is a push or pull on an object. It can move an object.
Forces have a unit of Newton's
Force is a vector so it has direction meaning it can positive or negative, or north, South, East west

What is the relation between electric intensity dn flux
The relation between the electric intensity and electric flux is that the electric flux is equal to the scalar product of electric flux intensity and vector area.
What is the relation between electric intensity and flux?The electric field is the field, which is surrounded by the electric charged. The electric field is the electric force per unit charge.
The intensity of this electric field is the number of electric field lines which are pass perpendicular to the unit element of fixed area.The flux of this electric field is the number of electric field lines which are pass normally to the fixed area.The electric flux can be given as,
[tex]d\phi =\vec E \;dA\cos \theta[/tex]
When angle is zero,
[tex]d\phi =\vec E \;dA\times1\\d\phi =\vec E \;dA[/tex]
Thus, the total flux is,
[tex]\phi=\oint_{}^{}\vec E.d\vec A[/tex]
Thus, the relation between the electric intensity and electric flux is that the electric flux is equal to the scalar product of electric flux intensity and vector area.

Why is red the last color seen at sunset?
A. It is bent by raindrops.
B. It is bent the most by the air.
C. It is scattered the least by the air.
D. It reflects off the atmosphere.
Answer: Within the visible range of light, red light waves are scattered the least by atmospheric gas molecules. So at sunrise and sunset, when the sunlight travels a long path through the atmosphere to reach our eyes, the blue light has been mostly removed, leaving mostly red and yellow light remaining.

The block is pulled to a position xi = 6. 20 cm from equilibrium and released. Find the potential energy stored in the spring when the block is 6. 20 cm from equilibrium
The value of potential energy stored in the spring when the block is 6. 20 cm from equilibrium is 1.65 J.
What is elastic potential energy?The elastic potential energy is the energy which is stored in a stretched spring. The elastic potential energy of a spring can be found by the following formula.
[tex]U_s=\dfrac{1}{2}kx^2[/tex]
Here, (k) is spring constant and (x) is the displacement of the spring.
The block is pulled to a position xi = 6. 20 cm from equilibrium and released. Thus,
[tex]x=6.20\rm \; cm[/tex]
Divide with 100 to convert its unit in meter,
[tex]x=0.062\rm \; m[/tex]
Let the value of spring constant is 860 N/m. Thus, put the values in the formula,
[tex]U_s=\dfrac{1}{2}kx^2\\U_s=\dfrac{1}{2}(860)(0.062)^2\\U_s=1.65\rm\; J[/tex]
Thus, the value of potential energy stored in the spring when the block is 6. 20 cm from equilibrium is 1.65 J.

a ball on a string is swung overhead in a horizontal circle with a radius of 0.66 m. what speed (in m/s) does the ball need to maintain for there to be a centripetal acceleration of 23 m/s2?
Answer:
The ball is moving in a horizontal circle.
The force acting towards the center of the circle is
F = M a = M * V^2 / R
a = V^2 / R simplifying equation
V = (a / R)^1/2 = (23 / .66)^1/2 = 5.90 m/s

Calculate the wavelength of the sound wave in air at STP.
A ray of monochromatic light passes from medium X into air. The refractive index of medium X is 1.52.
What is Snell's law?It states that the ratio of sine of angle of incidence and angle of refraction is equal to the refractive index of second medium to the first medium.
sini/sinr = n₁/n₂
Given the angle of incidence i = 25 degrees, angle of refraction r =40 degrees, refractive index of air n₁ =1, then refractive index of medium X is
n₂ = 1 x sin 40/sin25
n₂ = 1.52
Thus, the refractive index of medium X is 1.52.

A cannonball weighs 124.0 N in air, 89.0 N in salt water, and 30.0 N in an unknown liquid, Find the densities of the following: The cannonball, and the unknown liquid
The densities of the cannonball and the unknown liquid are 3.54kg/m³ and 2.686 kg/m³.
What is the buoyant force?When an object is fully or partially submerged in liquid, the vertical upward thrust is acting on the object, this force is called the buoyant force.
Salt Water exerts a buoyant force to the cannon ball = 124−89 = 35N, which equals the weight of water displaced.
The mass of water displaced is
W/g =35/10 =3.5 kg.
Since the density of salt water is 1kg/L, the volume displaced is 3.5L.
Therefore the density of the cannon ball is
=(124/10) /3.5 =3.54kg/L = 3.54kg/m³
The unknown liquid exerts a buoyant force of 124−30=94 N.
The density of this liquid is (94/10) /( 3.5 )=2.686 kg/liter = 2.686 kg/m³
Thus, the densities of the cannonball and the unknown liquid are 3.54kg/m³ and 2.686 kg/m³.
