Answer:
B) is perpendicular to the magnetic field
Answer:
Speed is the time rate at which an object is moving along a path while velocity is the rate and direction of an object's movement
Answer:
The strength of the source charge's electric field could be measured by any other charge placed somewhere in its surroundings. The charge that is used to measure the electric field strength is referred to as a test charge since it is used to test the field strength. The test charge has a quantity of charge denoted by the symbol q.

Answer:
The speed of stone traveling when it hits the ground = 49 m/s
Explanation:
Height of drop = 122.5 m
Given that distance the stone travels from its starting point
s(t) = 4.9t²
Substituting height
122.5 = 4.9t²
t² = 25
t = 5 seconds
So after 5 seconds stone hit the ground, we need to find velocity when t = 5 seconds.
Differentiating displacement with respect to time to get velocity,
s'(t) = 4.9 x 2 t = 9.8 t
Velocity when t = 5, s'(5) = 9.8 x 5 = 49 m/s
The speed of stone traveling when it hits the ground = 49 m/s
