Ahorizontal force of 199 n is applied to move a 55-kg cart (initially at rest) across a 8 m level surface. what is the final speed of the cart?

Final speed will be 7.60 m /sec

Explanation:

We have given horizontal force F = 199 N

Mass of the cart = 55 kg '

From newton's law acceleration will be

As initially cart is at rest so initial velocity u = 0 m/sec

Distance traveled s= 8 m

From third equation of motion  

v = 7.60 m /sec

adding a(n) to an electric circuit would increase the magnetic field around a wire;

b. solenoid

a solenoid is a type of electromagnet whose purpose is to generate a controlled magnetic field.

if the purpose of the solenoid is instead to impede changes in the electric current, a solenoid can be more specifically classified as an inductor rather than an electromagnet.
