Voltage=Energy/Charge, V=E/Q
V in volts V, E in joules J, Q in coulombs C.
or
Voltage= Current×Resistance, V=IR
V in volts V, I in amperes A and R in ohms Ω
Answer:
Yes
Explanation:
Newton's third law
For every action, there is an equal and opposite reaction.
SO if the apple is falling 9.8 m/s2 then the same force is pushing against it.
Hope this helps
Answer:
F = N*μ or F =m*g*μ
Explanation:
The friction force is defined as the product of the normal force by the corresponding friction factor.
When a body is in equilibrium over a horizontal plane its normal force value shall be equal to:
![N = m*g\\where:\\m=mass [kg]\\g=gravity [m/s^2]\\N= normal force [N]](https://tex.z-dn.net/?f=N%20%3D%20m%2Ag%5C%5Cwhere%3A%5C%5Cm%3Dmass%20%5Bkg%5D%5C%5Cg%3Dgravity%20%5Bm%2Fs%5E2%5D%5C%5CN%3D%20normal%20force%20%5BN%5D)
if we simplify this formula more for a balanced body on a horizontal plane, we will have.

Objects can only go so fast and that speed is called terminal velocity. so the answer is A
Answer:
(a) 2800 J
(b) 31.28 %
Explanation:
Heat intake, Q1 = 8950 J
Heat discard, Q2 = 6150 J
(a) Work = intake heat energy - discarded heat energy
W = Q1 - Q2 = 8950 - 6150 = 2800 J
(b) Efficiency = 1 - Q2 / Q1
Efficiency = 1 - (6150 / 8950) = 0.3128 = 31.28%
