<span>newton say that she must use her hand to put up the cup because the work is equal to force times it distance, that is in the same direction of the force applied. if carole used her hand to put up the cup, then he is not applying any work because the displacement is not in the same direction of the force</span>
b.
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

Possibly by the damage done compared to the previous ones.
V = 3.0 x 10⁸ m/s (This is the same for all types of electromagnetic waves)
f = 88.6 MHz = 8.86 x 10⁷ Hz
λ = ?
V = fλ
λ = V/f = (3 x 10⁸)/(8.86 x 10⁷)
= 3.4 m [Ans]
Hope this helps!
Current.A moving charge is an object that changes position to one particular obsever.
