Answer:
4 N
Explanation:
Electrostatic force is directly related to the charge of each object hence when the charge is doubled in only one of the objects, the force also double. If it's doubles on both objects, the force becomes four times. In this case, it's doubled on one object hence 2*2= 4 N
Because it is touching, the heat is being transferred via conduction.
Fill a pot of water and sit it on the stove, the water continues to heat until you turn it off. While in a energy transformation, the energy changes forms such as Chemical, kinetic.
The answer is solar flare. Solar flares are commonly accompanied by coronal mass ejection. Solar flares are periods when the sun is suddenly brighter at a spot at its surface. This is due to the ejection of electrons, ions, and atoms (plasma clouds) accompanied by electromagnetic waves.
Answer:
The coefficient of kinetic friction is 0.51.
Explanation:
Given that,
Applied force, F = 75 N
Mass of a box, m = 15 kg
The acceleration of the box is 3 m/s²
We need to find the coefficient of kinetic friction. It is given by the formula as follows :
Where,
, is the normal force
So, the coefficient of kinetic friction is 0.51.
