Astudent makes a short electromagnet by winding 590 turns of wire around a wooden cylinder of diameter d = 3.4 cm. the coil is connected to a battery producing a current of 4.8 a in the wire.
(a) what is the magnitude of the magnetic dipole moment of this device?
(b) at what axial distance z > > d will the magnetic field have the magnitude 5.4 µt (approximately one-tenth that of earth's magnetic field)?

which three statements are true about all alloys?

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.
