Answer: A satellite with a mass of 110 kg and a kinetic energy of 3.08×10^9 J must be moving at a speed of 7483 m/s.
Explanation: To find the answer we need to know about the kinetic energy of a body.
<h3>
How to solve the problem the equation of kinetic energy?</h3>
- We have the expression for kinetic energy of a body as,
![KE=\frac{1}{2}mv^2](https://tex.z-dn.net/?f=KE%3D%5Cfrac%7B1%7D%7B2%7Dmv%5E2)
![m=110kg\\KE=3.08*10^9J\\](https://tex.z-dn.net/?f=m%3D110kg%5C%5CKE%3D3.08%2A10%5E9J%5C%5C)
- We have to find the speed of the satellite,
![v=\sqrt{\frac{2KE}{m} } =\sqrt{\frac{2*3.08*10^9}{110} } =7.483*10^3 m/s](https://tex.z-dn.net/?f=v%3D%5Csqrt%7B%5Cfrac%7B2KE%7D%7Bm%7D%20%7D%20%3D%5Csqrt%7B%5Cfrac%7B2%2A3.08%2A10%5E9%7D%7B110%7D%20%7D%20%3D7.483%2A10%5E3%20m%2Fs)
Thus, we can conclude that, the velocity of the satellite will be 7438m/s.

Answer:
The charge pass through your hair dryer is 3000 C.
Explanation:
Given that,
Power = 1200 W
Voltage = 120 V
Flow time = 5 min
We need to calculate the current
Using formula of power
![P=VI](https://tex.z-dn.net/?f=P%3DVI)
![I=\dfrac{P}{V}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7BP%7D%7BV%7D)
Put the value into the formula
![I=\dfrac{1200}{120}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7B1200%7D%7B120%7D)
![I=10\ A](https://tex.z-dn.net/?f=I%3D10%5C%20A)
We need to calculate the charge pass through your hair dryer
Using formula of current
![I=\dfrac{Q}{t}](https://tex.z-dn.net/?f=I%3D%5Cdfrac%7BQ%7D%7Bt%7D)
![Q=It](https://tex.z-dn.net/?f=Q%3DIt)
Put the value into the formula
![Q=10\times5\times60](https://tex.z-dn.net/?f=Q%3D10%5Ctimes5%5Ctimes60)
![Q=3000\ C](https://tex.z-dn.net/?f=Q%3D3000%5C%20C)
Hence, The charge pass through your hair dryer is 3000 C.

Explanation:
Just did the test. Good Luck!
Answer:thrust is not a force,upthrust is a force
Explanation:thrust means do something forcefully and upthrust is a force that helps a ship float and pushes an object upwards
Answer:the force is needed to stretch it farther.
Explanation: the definition of force is push or pull so imagine stretching a rubber band your pulling the band which means you increase the force.
