Answer:
29.412m/s
Explanation:
where F= force, m= mass, and a=acceleration
we also know that,
a = Δv / t where Δv = change in velocity and t = time
thus F = m ( Δv / t)
![50000=850(\frac{v}{0.5})](https://tex.z-dn.net/?f=50000%3D850%28%5Cfrac%7Bv%7D%7B0.5%7D%29)
Δv
29.412m/s=Δv
"Gamma rays" is the name that we call the shortest of all electromagnetic waves. They're shorter than radio waves, microwaves, infrared waves, heat waves, visible light waves, ultraviolet waves, and X-rays. They extend all the way down to waves that are as short as the distance across an atom.
Being so short, they carry lots of energy. They can penetrate many materials, and they can damage living cells and DNA. They're dangerous.
The sun puts out a lot of gamma radiation. The atmosphere (air) filters out a lot of it, otherwise there couldn't even be any life on Earth.
As soon as astronauts fly out of the atmosphere, they need a lot of shielding from gamma rays.
You know the precautions we take when we're around X-rays. The same precautions apply around gamma rays, only a lot more so.
It's only in the past several years that we've learned how to MAKE gamma rays without blowing things up. Also, how to control them, and how to use them for medical and industrial applications.
Answer:
553.1m
Explanation:
When an object moves at constant velocity we can express this movement like V=x/t, where V is the velocity, x is the displacement and t is the time spent on it.
In that way, the expression x=V.t give us the displacement from t=0s until t=51s, but we have to sum the initial distance from the point A.
x=242m +V.t = 242m + (6.1m/s x 51s) = 553.1m
Answer:
The inductance of the inductor is 35.8 mH
Explanation:
Given that,
Voltage = 120-V
Frequency = 1000 Hz
Capacitor ![C= 2.00\mu F](https://tex.z-dn.net/?f=C%3D%202.00%5Cmu%20F)
Current = 0.680 A
We need to calculate the inductance of the inductor
Using formula of current
![I = \dfrac{V}{Z}](https://tex.z-dn.net/?f=I%20%3D%20%5Cdfrac%7BV%7D%7BZ%7D)
![Z=\sqrt{R^2+(L\omega-\dfrac{1}{C\omega})^2}](https://tex.z-dn.net/?f=Z%3D%5Csqrt%7BR%5E2%2B%28L%5Comega-%5Cdfrac%7B1%7D%7BC%5Comega%7D%29%5E2%7D)
Put the value of Z into the formula
![I=\dfrac{V}{\sqrt{R^2+(L\omega-\dfrac{1}{C\omega})^2}}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7BV%7D%7B%5Csqrt%7BR%5E2%2B%28L%5Comega-%5Cdfrac%7B1%7D%7BC%5Comega%7D%29%5E2%7D%7D)
Put the value into the formula
![0.680=\dfrac{120}{\sqrt{(100)^2+(L\times2\pi\times1000-\dfrac{1}{2\times10^{-6}\times2\pi\times1000})^2}}](https://tex.z-dn.net/?f=0.680%3D%5Cdfrac%7B120%7D%7B%5Csqrt%7B%28100%29%5E2%2B%28L%5Ctimes2%5Cpi%5Ctimes1000-%5Cdfrac%7B1%7D%7B2%5Ctimes10%5E%7B-6%7D%5Ctimes2%5Cpi%5Ctimes1000%7D%29%5E2%7D%7D)
![L=35.8\ mH](https://tex.z-dn.net/?f=L%3D35.8%5C%20mH)
Hence, The inductance of the inductor is 35.8 mH
