Answer:
Explanation:
True
Average speed is the ratio of total distance traveled to the total time taken and average velocity is total displacement to the total time.
And we know distance is either equal to or greater than displacement so we can say that for equal time interval magnitude of average velocity can never be greater than average speed.
Answer:
B
Explanation:
Is the equilibrium stable or unstable for the third charge
Complete question:
Part A:) The fictional rocket ship Adventure is measured to be 50 m long by the ship's captain inside the rocket.When the rocket moves past a space dock at 0.5c , space-dock personnel measure the rocket ship to be 43.3 m long. The rocket ship Adventure travels to a star many light-years away, then turns around and returns at the same speed. When it returns to the space dock, who would have aged less: the space-dock personnel or ship's captain?
Part B: What is the momentum of a proton traveling at 0.62 c ?
Answer
a)Who would have aged less=The Captain would have aged less
b) ![p=3.96*10^{-19}kgm/s](https://tex.z-dn.net/?f=p%3D3.96%2A10%5E%7B-19%7Dkgm%2Fs)
Explanation:
From the question we are told that
Length measured by captain ![l_c=50m](https://tex.z-dn.net/?f=l_c%3D50m)
Speed of rocket past tje space dock ![V=0.5c](https://tex.z-dn.net/?f=V%3D0.5c)
Length measured by space-dock personnel ![l_c=43.3m](https://tex.z-dn.net/?f=l_c%3D43.3m)
a)
Generally time moves slower when moving at speed of light, due to time dilation or variation.
Who would have aged less=The Captain would have aged less
b)
Generally the equation for Relativistic Momentum is mathematically given as
![p=\frac{m*v}{1 - v^2/c^2}](https://tex.z-dn.net/?f=p%3D%5Cfrac%7Bm%2Av%7D%7B1%20-%20v%5E2%2Fc%5E2%7D)
![p=\frac{1.67*10^2-27*0.62*3.0*10^8)}{\sqrt{ 1 -0.6^2}}](https://tex.z-dn.net/?f=p%3D%5Cfrac%7B1.67%2A10%5E2-27%2A0.62%2A3.0%2A10%5E8%29%7D%7B%5Csqrt%7B%201%20-0.6%5E2%7D%7D)
![p=3.96*10^{-19}kgm/s](https://tex.z-dn.net/?f=p%3D3.96%2A10%5E%7B-19%7Dkgm%2Fs)
Answer:
3×10^-12 C
Explanation:
The total of the three charges is ...
(-3 +8 +4)×10^-12 C = 9×10^-12 C
Assuming the charge is equally distributed between the balls when they are brought in contact, the charge on each ball will be ...
(9/3)×10^-12 C = 3×10^-12 C
