This is ur answer....
<em></em>
<em>The heat is transferred by the process of conduction of heat.
</em>
<em>
It is given that, Jimmy held the end of a metal bar over a fire while holding on to the opposite end.
</em>
<em>
After some time, the end he was holding began to get very hot.
</em>
<em>
The process of traveling heat from one end of the bar to the other end is called conduction. It is the process of transfer of heat by the interaction of particles and motion of electrons.</em>

Answer:90N
Explanation:
Mass=30kg
Centripetal acceleration=3m/s^2
centripetal force=mass x centripetal acceleration
Centripetal force=30 x 3
Centripetal force =90
Centripetal force =90N
Answer:
Plane spacing, 
Explanation:
It is given that,
Wavelength of x-ray, 
Angle the x-ray made with a set of planes in a crystal causing first order constructive interference is 30 degrees
We need to find the plane spacing. It is based on Bragg's law such that,
d is plane spacing
n = 1 here
So, the plane spacing is 
.
Answer:
Explanatio
Increasing the speed of the relative motion between the coil and the magnet – If the same coil of wire passed through the same magnetic field but its speed or velocity is increased, the wire will cut the lines of flux at a faster rate so more induced emf would be produced. 3)n:
