For a converging lens, a ray arriving parallel to the optic axis
a. appears to come from the principal focal point.
b. passes through the principal focal point.
c. passes through the "other" focal point.
d. appears to come from the "other" focal point.
Answer:
b. passes through the principal focal point.
Explanation:
Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
A lens can be defined as a transparent optical instrument that refracts rays of light to produce a real image.
Basically, there are two (2) main types of lens and these includes;
I. Diverging (concave) lens.
II. Converging (convex) lens.
A converging lens refers to a type of lens that typically causes parallel rays of light with respect to its principal axis to come to a focus (converge) and form a real image. This type of lens is usually thin at the lower and upper edges and thick across the middle.
For a converging lens, a ray arriving parallel to the optic axis passes through the principal focal point.
The correct option is b. passes through the principal focal point.
The following information should be considered:

A roller coaster is moving 10 m/s and a mass of 7 kg. The roller coaster has
energy. Calculate it
HELP ASAP!!
Hello,
QUESTION)A roller coaster is moving 10 m/s and a mass of 7 kg. The roller coaster has kinetic energy.
✔ We have : Ek = 1/2m x v²; with Ek in J, m in kg and v in m/s
Ek = 1/2 x 7 x 10²Ek = 350 JXander goes airborne on his scooter as he exits a half-pipe at Newton's Skate Park. Xander and his scooter have a total mass of 50 kg. The net force acting on Xander and the scooter is 25N. What is Xander's acceleration?
Hello,
QUESTION)According to the 2nd Newton's law,
✔ We have : F = m x a ⇔ a = F/m; with F in N, m in kg, a in m/s²
a = 25/50a =0.5 m/s²Therefore Xander's acceleration is 0.5 m/s².
The total mass of Xander and his scooter is 50 kg and the net force acted due to Xander and his scooter is 25 N then the acceleration will be 0.5 m/s².
What is Acceleration?Acceleration is the rate at which the speed and orientation of a moving object change over time. When a spot or object moves faster or slower along a straight line, it is said to be accelerated. Even though the speed is constant, motion on a circle accelerates so because the direction is always shifting. Both by and to acceleration for all other types of motion.
It is a vector quantity because it has both magnitude and direction.
As per the given information provided by the question,
Mass, m = 50 kg
Force, F = 25 N
F = ma
25 N = 50 × a
a = 25/50
a = 0.5 m/s².
Therefore, the acceleration of Xander's acceleration will be 0.5 m/s²

If you are sitting 8.20 m from a
70.0 W speaker, what is the
sound level in dB?
(Treat the speaker as a point source.)
(Unit = dB)
The sound level will be 109 decibels. If a person exceed hear a sound more than the certain sound level, the person hearing may damage.
What is sound level?Sound level is the intensity to measure the sound. Decibels are used to quantify sound level.
Sound level or the sound intensity is the ratio of the power to the surface area;
[tex]\rm Intensity = \frac{Pow\pi er }{Surface \ area} \\\\ \rm Intensity = \frac{70}{ 4 \times \pi \times 8 \times 20^{2} } \\\\ I = \ 0.082 \ W/m^2[/tex]
The conversion of the obtained value into the decibel as;
[tex]\rm I = 10 \times log \frac{I}{1 \TIMES 10^{-12}} \\\\\ I = 109 \ decibel[/tex]
Hence, the sound level will be 109 decibels.

Plzzz help!! A stationary speed gun emits a
microwave beam at 2.10x1010 Hz. It
reflects off a car and returns 1030 Hz
higher. What is the speed of the car?
(Unit = m/s)
Answer:
The speed of the car is 14.7m/second or 15 m/second approximately.
Explanation:
A microwave beam at [tex]2.10\times10^1^0Hz[/tex] is generated by a stationary speed gun. It bounces off a car and returns at a higher frequency of 1030 Hz. The car's observed frequency would be the product of adding the two frequencies. That is to say,
F =[tex]2.1\times10^1^0+1030[/tex] =[tex]2.100000103\times10^1^0Hz[/tex]
Using doppler effect formula
[tex]F=\frac{C}{C-V}\times f[/tex]
Where
F = observed frequency
f = source frequency
C = speed of light = [tex]3\times10^8[/tex]
V = speed of the car
Putting the values in the formula -
[tex]2.100000103\times10^1^0=\frac{3\times10^8}{3\times10^8-V}\times2.1\times 10^1^0[/tex]
[tex]\frac{2.100000103\times10^1^0}{2.1\times10^1^0}[/tex] [tex]=\frac{3\times10^8}{3\times10^8-V}[/tex]
[tex]1.000000049=\frac{3\times10^8}{3\times10^8-V}[/tex]
by cross multiplication ,
300000014.7 - 1.000000049V = [tex]3\times10^8[/tex]
Collect the like terms
1.000000049V = 14.71429
Make V the subject of formula
V = [tex]\frac{14.71429}{1.000000049}[/tex]
V = 14.7 m/s
Therefore , the speed of the car is 15m/second approximately.

1. A force of 52N acts upon a 4kg block sitting in the ground. Calculate the acceleration of the object (show work)
2. An object of mass 10kg is accelerated upward at 2 m/s^2. What force is required? (Show work)
3. What is the mass of an object if a force of 17N caused it to accelerate at 1.5m/s^2? (Show work)
Answer:
1. Acceleration = 6.25 m/s²
2. Force = 20 Newton.
3. Mass = 11.33 kg
Explanation:
Given the following data;
1. Force = 25N
Mass = 4kg
To find the acceleration;
Acceleration = force/mass
Acceleration = 25/4
Acceleration = 6.25 m/s²
2. Mass = 10kg
Acceleration = 2 m/s²
To find the force required;
Force = mass * acceleration
Force = 10 * 2
Force = 20 Newton.
3. Force = 17N
Acceleration = 1.5 m/s²
To find the mass;
Mass = force/acceleration
Mass = 17/1.5
Mass = 11.33 kg

R. Una bailarina gira con una frecuencia de 1hz y momento de inercia i = 28.14kg . M2. Calcule su velocidad de giro cuando disminuye su momento de inercia a la mitad.
Answer:
w = 4π rad / s
Explanation:
When the dancer is turning, the body is isolated so the angular momentum is conserved.
initial
L₀ = I₀ w₀
final
L_f = I w
in this case it indicates that the initial moment is Io = 28.14 kg m² and the final moment is half
I = I₀ / 2
frequency and angular velocity are related
w = 2π f
w = 2π 1
wo = 2π rad / s
how angular momentum is conserved
L₀ = L_f
I₀ w₀ = I w
w = [tex]\frac{I_o}{I}[/tex] w₀
let's calculate
w = 2 2π
w = 4π rad / s

Explain how do you determine the intensity of earthquake
Answer:
The Richter scale measures the largest wiggle (amplitude) on the recording, but other magnitude scales measure different parts of the earthquake. The USGS currently reports earthquake magnitudes using the Moment Magnitude scale, though many other magnitudes are calculated for research and comparison purposes.
Answer:
To measure the magnitude of an earthquake, the American scientist Charles Richter developed a scale in 1935. Known as the Richter scale, it assigns a number based on the height of the waves on a seismogram (the visual output of a seismograph). Seismographs measure ground motion, including the energy released by an earthquake.
