16) A student pushes four students on skateboards. She pushes as hard as she can each time. She measures how far each student
goes before stopping. Which is most likely to happen?
A) The biggest student will go the furthest.
B) The smallest student will go the furthest.
c) Each student will go further than the last.
D) All four student will go about the same distance.
Answers
Answer:
B
Explanation:
It would be diffrent if on a downward slope but assuming your going straight it would be the smallest student.
The smallest student will go furthest if all the students push with the same amount of force. Therefore, option (B) is correct.
What is Newton's second law of motion?According to Newton’s second law of motion, the force equals the mass of the body times the acceleration of that body when the body has constant mass.
This law states that the acceleration of a body depends on two variables. The first one is the mass of the body and the force acting on the body. The acceleration of a body is directly proportional to the net force acting on the body and inversely proportional to the mass.
Newton’s second law can be expressed in the equation as shown below:
[tex]F= ma[/tex]
or,
[tex]a=\frac{F}{m}[/tex]
Acceleration or gaining speed of a body happens when a force acts on it.
When all four students are pushed by the same amount of force then the acceleration of the smallest student will be greatest as the mass of the smallest student will be least.
Therefore, the smallest student will go furthest in comparison to all other students.

Which two types of electromagnetic waves have higher frequencies than the waves that make up ultraviolet light?
o radio waves and infrared light
O visible light and X-rays
O microwaves and gamma rays
gamma rays and X-rays
Answers
Answer:
Gamma rays and x rays
Explanation: just took the test
Gamma rays and X-rays have higher frequencies than the waves that make up ultraviolet light. Hence option D is correct.
What is Electromagnetic Spectrum ?Electromagnetic spectrum is nothing but the range of wavelengths or frequencies on which electromagnetic radiation extend. it is whole distribution of electromagnetic waves according to frequency or wavelength. Electromagnetic wave is nothing but a photon which carries energy. Photon wave has frequency, wavelength as well as amplitude.
Electromagnetic spectrum is show in figure.
There is inverse relation between wavelength and frequency as υ = c/λ
where υ is the frequency, λ is the wavelength and c is the speed of light.
as wavelength increases, frequency decreases vice verse.
In this figure we can see that radio waves has highest wavelength hence it has lowest frequency. X ray and gamma rays has lowest wavelength hence it has highest frequency.
Hence option D is correct.

Answers
Answer:
A prism causes the different wavelengths of light or colors that can be found in white light because the prism is white, and white light contains all colors in the visible light spectrum. So an object that reflects all the colors in the visible light spectrum will appear white in color because white light contains all colors in the visible light spectrum.

You have your headphones turned all the way up (100 dB).
a. If you want them to sound half as loud, to what decibel level must the music be set?
b. If you want them to sound 1/4 as loud, to what decibel level must the music be set?
Answers
Answer:
a. 90 dB
b. 80 dB
Explanation:
The given parameter of the sound is as follows;
The level to which the headphones are tuned = All the way up
The intensity of the sound of the headphones when tuned all the way up = 100 dB
a. The relationship between level change in loudness, ΔL, and the ratio of loudness, 'x', is presented as follows;
ΔL = 10·log₂(x) ≈ 33.22·log(x)
Therefore, for a sound to be half as loud, we have x = 1/2, therefore;
ΔL = 10·log₂(1/2) = 10·log₂(2⁻¹) = -10 ≈ 33.22·log(1/2)
The change in the intensity level for a sound half as loud, ΔL = -10 dB
Given that the sound was initially at 100 dB, the new level for a sound half as loud = 100 dB + ΔL = 100 dB - 10 dB = 90 dB
The decibel level the music must be set for a sound half as loud = 90 dB
b. In order for the sound to be 1/4 as loud, we have;
ΔL = 10·log₂(1/4) = 10·log₂(2⁻²) = -20
Therefore, the change in the level of the sound intensity level, ΔL by -20 dB will given a sound that is 1/4 as loud
The initial intensity level = 100 dB
The intensity level for a sound 1/4 as loud = 100 dB - 20 dB = 80 dB

A 2800 kg truck moving at 12 m/s to the right hits a stopped 1100 kg car. What is the combined velocity the moment they stick together?
Answers
Answer:
The combined velocity is 8.61 m/s.
Explanation:
Given that,
The mass of a truck, m = 2800 kg
Initial speed of truck, u = 12 m/s
The mass of a car, m' = 1100 kg
Initial speed of the car, u' = 0
We need to find the combined velocity the moment they stick together. Let it is V. Using the conservation of momentum.
[tex]m_1v_1+m_2v_2=(m_1+m_2)V\\\\V=\dfrac{m_1v_1+m_2v_2}{(m_1+m_2)}\\\\V=\dfrac{2800\times 12+0}{2800+1100}\\\\V=8.61\ m/s[/tex]
So, the combined velocity is 8.61 m/s.

A pressure of 7x10^5N/m is applied to all surfaces of a copper cube (of sides 25 cm) what is the fractional change in volume of a cube? ( for copper B= 14x10^10N/m)
Answers
Answer:
The correct solution is "[tex]5\times 10^{-4}[/tex] %".
Explanation:
The given values are:
Pressure,
[tex]\Delta P=7\times 10^5 \ N/m[/tex]
for copper,
[tex]B=14\times 10^{10} \ N/m[/tex]
As we know,
The Bulk Modulus (B) = [tex]\frac{\Delta P}{-\frac{\Delta V}{V} }[/tex]
or,
The decrease in volume will be:
= [tex](\frac{\Delta V}{V})\times 100 \ percent[/tex]
then,
= [tex]\frac{\Delta P}{B}\times 100 \ percent[/tex]
On putting the values, we get
= [tex]\frac{7\times 10^5}{14\times 10^{10}}\times 100 \ percent[/tex]
