Answer:
The forms of energy involved are
1. Kinetic energy
2. Potential energy
Explanation:
The system consists of a ball initially at rest. The ball is pulled down from its equilibrium position (this builds up its potential energy) and then released. The released ball oscillates due to a continuous transition between kinetic and potential energy.
Well I can't see the following physical properties you talked about in the question.
Mass per unit volume ratio is called density.
Answer:
365 days
So The Final Answer is a Year
D is the answer
Explanation:
<u>Answer</u>
1.667 m/s²
Using the Newton's second law of motion;
force is directly proportional to the rate of change of momentum and it takes place in the direction of force.
i.e F = change in momentum
F = (mv - mu)/t
=m(v-u)/t
= ma
∴ F =ma
a = F/m
= 150/90
= 1.667 m/s²
Answer:
A. the magnitude of the force between the spheres is 3.97 x 10⁻⁴ N
B. the magnitude of its initial acceleration is 5.83 m/s²
Explanation:
given information:
metal sphere's mass, m = 0.1 g = 1 x 10⁻⁴ kg
charge, q = -21 nC = -2.1 x 10⁻⁸
r = 10 cm = 0.1 m
What is the magnitude of the force between the spheres?
F₁₂ = k q₁q₂/r²
= ( 9 x 10⁹) (-2.1 x 10⁻⁸)²/(0.1)²
= 3.97 x 10⁻⁴ N
If the upper sphere is released, it will begin to fall. What is the magnitude of its initial acceleration?
mg - F₁₂ = ma
a = g - (F₁₂/m)
= 9.8 - (3.97 x 10⁻⁴/1 x 10⁻⁴)
= 5.83 m/s²
