Answer:
Explanation:
Let m and e are the mass and charge of an electron. It is accelerated from rest through a potential difference V and are then deflected by a magnetic field that is perpendicular to their velocity. Let v is the velocity of the electron. It can be calculated as :
When the electron enters the magnetic field, the centripetal force is balanced by the magnetic force as :
or
So, the radius of the resulting electron trajectory is 
. Hence, this is the required solution.
Decreases
Explanation:
The acceleration due to gravity on a body decreases with depth.
Acceleration due to gravity is the change in velocity with time of a body as result of the pull of gravity or gravitational force.
- The acceleration due to gravity tend to pull all bodies to the center of the earth.
- As body moves away from the center of the earth, the pull becomes very more and acceleration increase.
- But when a body approaches the center of the earth, the acceleration reduces.
- At depth, the acceleration due to body of a body begins to decrease.

Answer:
as an object gains speed it gains kinetic energy
Explanation:
i am mixed with the very first one i dont really know if its right so if its wrong my bad
Explanation:
The tension on an object is equal to the mass of the object x gravitational force plus/minus the mass x acceleration. Tension Formula Questions: 1) There is a 5 kg mass hanging from a rope.
Answer:
I think you would need too time your friend and know how too divide that time by other racers to see how much faster she needs to get. I THINK.
