To solve this problem we will apply the principles of energy conservation. The kinetic energy in the object must be maintained and transformed into the potential electrostatic energy. Therefore mathematically


Here,
m = mass (At this case of the proton)
v = Velocity
k = Coulomb's constant
= Charge of each object
r= Distance between them
Rearranging to find the second charge we have that

Replacing,


Therefore the charge on the sphere is 3.6531nC
Answer:
An increase in angular speed due to conservation of energy priciple.
Explanation:
This leads to a decrease in your moment of inertia. This means that your angular velocity must increase as a result of conservation of energy principle and therefore you will spin faster.
It's also the same way this conservation of energy principle applies to ice skaters that makes them spin faster when they suddenly draw their arms inwards.
it's Also called aerobic exercise, endurance exercise includes activities that increase your breathing and heart rate such as walking, jogging, swimming, and biking. Endurance activity keeps your heart, lungs and circulatory system healthy and improves your overall fitness.
Answer:
80 N
Explanation:
For A + B: the net force is 100 N = (mA + mB)*a
a = 100/(20 + 5) = 100/25 = 4 m/s²
For A, the net force = mA * a = 20 * 4 = 80 N
D) It isn't accelerating
This is because if both sides are pushing with the exact same force, than one force is not overpowering the other, therefor the wheelbarrow would not be moving.
