Explanation:
In the given situation two forces are working. These are:
1) Electric force (acting in the downward direction) = qE
2) weight (acting in the downward direction) = mg
Therefore, work done by all the forces = change in kinetic energy
Hence, 
It is known that the weight of electron is far less compared to electric force. Therefore, we can neglect the weight and the above equation will be as follows.
v = 
= 592999 m/s
Since, the electron is travelling downwards it means that it looses the potential energy.
I think it's 3. within an outer arm
Answer: The principle of conservation of energy, angular speed and centripetal force
Explanation:
At point A, the car experienced maximum of potential energy
As it moves down the hill, the potential energy decreases while the kinetic energy increases.
The maximum kinetic energy of the car is needed for the attainment of enough centripetal force to help the car move through the loop without falling .
Answer:
I don't know
Explanation:
But if you need help or reference America's GDP is 19.8 trillion dollars it spends over 2 to 3 percent of its budget on the military and the military's budget is 250 billion dollars
PS: sorry if the reference didn't help and if this doesn't help write dow the problem and download PHOTO MATH take a picture and buala and if you need to show your work just click on the button that says brake down problem and it'll show you and teach you the steps
