Explanation:
Mass and energy are closely related. Due to mass–energy equivalence, any object that has mass when stationary (called rest mass) also has an equivalent amount of energy whose form is called rest energy, and any additional energy (of any form) acquired by the object above that rest energy will increase the object's total mass just as it increases its total energy. For example, after heating an object, its increase in energy could be measured as a small increase in mass, with a sensitive enough scale.
Answer:
Electrons are negatively charged and are deflected on a curving path towards the positive plate. Neutrons have no charge, and continue on in a straight line.
Answer: a) Twice Chuck's
Explanation:
If the angular speed is constant, as the merry - go -round is a rigid body, so the distance between two points must remain the same, it is needed that the points farther the center, move faster than the ones closer to it.
There exists a relationship between tangential and angular speed, as follows, that relates the definitions of linear and angular speed, and the angle definition:
angle = arc / radius ⇒ Δθ/Δt = Δs/Δt / r ⇒ ω = v/r ⇒ v = ω. r
If ω is constant, v is directly proportional to r, distance to the center (radius in a circular platform), so if r is twice for Andrea, her tangential speed must be twice Chuck's.

Answer:
The electric charge passes is 15.2 C.
Explanation:
The electric current is drawn from a battery = 16 A
The diameter of copper wire is = 5 mm
The length of copper wire is = 1.52 m
Running time of starter motor before the start of car engine = 0.95 s
Therefore, the current 16 A passes through the copper wire for 0.95 seconds.
The calculation of electric charge passes:
