Answer:

We would be spending  more money without using solor

Explanation:

Renewable energy is also about ensuring our quality of life and for many it's about energy independence. I have solar panels which produce most of my electricity, when the city raised our rates by 40% it made little difference on my bill, if I hadn't installed my solar system it would have been an additional $80 per month.

A student uses a spring to launch a marble vertically in the air. The mass of the marble is
Fed [463]

Answer:

the maximum height reached by the marble is 11.84 m.

Explanation:

Given;

mass of the marble, m = 0.02 kg

extension of the string, x = 0.08 m

force applied to the string, F = 58 N

Apply the principle of conservation of energy;

elastic potential energy = gravitational potential energy

¹/₂fx = mgh

h = \frac{Fx}{2mg} \\\\h = \frac{58 \ \times \ 0.08}{2 \ \times \ 0.02 \ \times \ 9.8} \\\\h = 11.84 \ m

Therefore, the maximum height reached by the marble is 11.84 m.

Which forces are shown on a free body diagram?
notsponge [240]

Answer:

What is a Free Body Diagram?

The free body diagram helps you understand and solve static and dynamic problem involving forces. It is a diagram including all forces acting on a given object without the other object in the system. You need to first understand all the forces acting on the object and then represent these force by arrows in the direction of the force to be drawn.
