Acoil of 1000 turns encloses an area of 25cm2. it is rotated in 0.010 s from a position where its plane is perpendicular to earth’s magnetic field to one where its plane is parallel to the field. if the strength of the field is 6.0×10−5t, what is the average emf induced in the coil?

Emf will be 0.015 volt

Explanation:

We have given number of turns N = 1000

Area

Time t = 0.010 sec

Magnetic field

Since plane is perpendicular to the magnetic field so

We know that emf is given by

spare some change and give it to the poor

explanation:

plz : ((

note: the given question is incomplete.

complete question is given below.

which is an example of kinetic energy?

a. the energy stored in ethanol  

b. a hockey puck sliding across the ice  

c. a compressed spring  

d. a ball sitting at the top of a ramp

solution: the kinetic energy is the energy posses by the virtue of the motion of the object.

in the given options, a, c and d are the example of potential energy because it is the energy posses by the virtue of the rest of the object. but option b has the kinetic energy as the object is in motion.

hence, a hockey puck sliding across the ice   is the apex example of kinetic energy.

so, the option (b) a hockey puck sliding across the ice   is the correct option.
