Well let's see:
A). No. A capacitor doesn't measure anything.
B). No. The power delivered to the circuit is determined by
the battery or power supply and all the things in
the circuit that dissipate energy. A capacitor doesn't
do any of these things.
C). No. If any current actually flows between its plates,
the capacitor is shot and can't do its job, and
must be replaced.
D). Yes. A capacitor stores charges on its plates, and
electrical energy in the field between its plates.
Answer:
Gravity, also called gravitation, in mechanics, the universal force of attraction acting between all matter. ... On Earth all bodies have a weight, or downward force of gravity, proportional to their mass, which Earth's mass exerts on them. Gravity is measured by the acceleration that it gives to freely falling objects
1 : A force of attraction that tends to draw particles or bodies together.
2 : The attraction of bodies by the force of gravity toward the center of the earth.
3 : Great seriousness.
<span>KE = 1/2 * m * v^2 = 1/2 * 30 * 20^2 = 1/2 * 30 * 400 = 6000 J</span>
Answer:
W = F * s
Work done equals applied force * distance traveled
Apparent weight = M g (1 - sin θ) since some of applied force will lighten sled
μ = coefficient of kinetic friction
F cos θ = force applied to motion of sled
s = distance traveled
[μ M g (1 - sin θ)] cos θ * s = work done in moving sled
Note that F = μ M g if applied force is in the horizontal direction
Answer:
μs = 0.333 and μk = 0.24
Explanation:
Mass of crates = 22kg
F = 72newton
F =μR
Also given that g = 9.8m/s^2 which is that acceleration due to gravity
Hence R = N = mg
= 9.8 × 22
= 215.6 newton
F is frictional force
μ is coefficient of friction
N or R is normal reaction
Hence, the static friction
F =μsR
72 = μs × 215.6
μs = 72/215.6
μs = 0.333
The kinetic friction coefficient
F =μkR
When F = 52N and R = N = 215.6N
52 = μk × 215.6
μk = 52/215.6
μk = 0.24
