Newton's first law actually states that a force isn't needed to keep an object moving, so no.
Answer:
The electric potential (voltage)
produced by a point charge
, at any point in space, is given by the following equation:
Where:
is the Coulomb's constant
is the distance
The result is a scalar quantity, is defined as the electric potential energy per unit of charge and determines the electric influence exerted by the charge on that point of space.
Answer:
Vx = 350m/s
Vy = 656.99 m/s
Explanation:
at the time of drop, the horizontal velocity of the object is same as of plane.
Since friction is ignored, horizontal velocity remains unchanged.
Vx = 350m/s
but the Vy increases due to gravitational acceleration
V^2 - U^2 = 2as
V: FINAL VELOCITY
U: INITIAL VELOCITY
U = 0 m/s
