What type of energy does a pv cell create ?
Alex_Xolod [135]

Answer:  Solar Photovoltaic (PV) cells generate electricity by absorbing sunlight and using that light energy to create an electrical current. There are many PV cells within a single solar panel, and the current created by all of the cells together adds up to enough electricity to help power your school, home and businesses.

A 2.55 kg block starts from rest on a rough inclined plane that makes an angle of 60 degree with the horizontal. the coefficient
lorasvet [3.4K]

Answer:

Change in mechanical energy = work done by friction

so it is equal to

W = -8.16 J

Explanation:

As we know that change in mechanical energy must be equal to the work done by non conservative forces only

So here when block moves down the inclined plane then the work done by friction force is given as

W = F.d

here we have

F = \mu F_n

here we know that

F_n = mg cos\theta

so we have

F_n = 2.55(9.81)(cos60)

F_n = 12.5 N

Now the friction force on the block is given as

F_f = \mu F_n

F_f = 0.25 \times 12.5

F_f = 3.13 N

now work done by the friction is given as

W = -(3.13)(2.61)

W = -8.16 J

What is the relation between inertia and mass?
skelet666 [1.2K]

Answer:

"The tendency of an object to resist changes in its state of motion varies with mass. Mass is that quantity that is solely dependent upon the inertia of an object. The more inertia that an object has, the more mass that it has. A more massive object has a greater tendency to resist changes in its state of motion."
