D= Mass over Volume or M/V
and if needed m*d = V and vise versa
They make it so you would exert less force and make things easier to move
Answer:
The power of the mirror is -17.24 diopter.
Explanation:
Magnification of an image,m = 
Distance of the object from the mirror = u = 29.0 cm
Distance of an image from the mirror = v
Magnification = 
Focal length of mirror = -5.8 cm =-0.058 m
Power of the lens = P
Answer:
C. Electric energy
Explanation:
A generator is designed to convert chemical energy to mechanical energy and them electrical energy.
- It is an alternate source of electricity for most homes and industrial establishments.
- The source of energy for the generator is a fuel usually fossil fuels.
- This energy source is ignited and it produces heat energy which drives the motion of the pistons in the set.
- As the piston moves, an magnetic field is cut through by a conducting wire.
- This inducts the production of currents.
Yes ... the law of reflection states that the angle of incidence is equal to the angle of reflection <em /><em>
it also states that the incident ray reflected ray and the normal at the point of incidence lie on the same plane....;
