A 12 n cart is moving on a horizontal surface with a coefficient of kinetic friction of 0.20. what force of friction must be ove
jonny [76]

We must remember that the total net force equation at constant velocity is:

<span>F – Ff = 0</span>

of

F - µN = 0

Using Newton's 2nd Law of Motion:<span>

F = m a 

<span>Where,

F = net force acting on the body 
m = mass of the body 
a = acceleration of the body 

Since the cart is moving at a constant velocity, then acceleration is zero, hence the working equation simplifies to 

F = net Force = 0 

Therefore, 

F - µN = 0 

where 

µ = coefficient of friction = 0.20 
N = normal force acting on the cart = 12 N 

Therefore, 

F - 0.20(12) = 0 

<span>F = 2.4 N </span></span></span>

What are the disadvantages of wind power?
jek_recluse [69]
<span>Wind power is produced from the wind turbines or sails that uses air flow to convert it into mechanical power. It is an alternative to fossil fuel burning, it is all around, renewable, clean, produces no greenhouse gases and uses little land. The advantages of wind power have been greatly praised by many. However, it has disadvantages. Wind power especially at farm is noisy and may spoil the view for their neighboring people. Also the amount of electricity depends on the strength of the wind. If no wind is around, no electricity is produced. </span>

Which statement best explains why a wet saw used to cut through a fine optical crystals is constantly lubricated with oil
daser333 [38]

The major reason why a wet saw that is used in cutting optical crystals is constantly lubricated with oil is largely due to friction, lubrication decreases friction and minimises the increase of internal energy.

Friction is basically the coming together of two parts that rubs against each other, it causes heat and lead to  deterioration of surfaces, it can also lead to wear and tear.

Although, despite it down side, friction is desire-able in most applications

e.g the brake system of vehicles, and if not for friction, we humans cannot walk without falling
