Answer:
C
Explanation:
Radiation affects both cancer cells and healthy cells, but it affects cancer cells more.
Permanent magnet. An induced magnet would be created when a piece of iron (for example) is in contact with a magnet. Temporary magnets would be something like an electromagnet. Bar magnets are permanently magnetic unless we heat them or hammer them to cause their domains to loose alignment.
Answer:

Explanation:
The area of the circular loop is given by:
The magnetic flux is given by:
is parallel to 
and is constant in magnitude and direction therefore:
Part A)
initially the flux is 
after the interval ![\Delta t= 2.4 [m/s]](https://tex.z-dn.net/?f=%5CDelta%20t%3D%202.4%20%5Bm%2Fs%5D)
the flux is
now, the EMF is defined as:
,
if we consider very small then we can re-write it as:
then:
![\epsilon =- \frac{-0.12}{0.0024} = 50 [V]](https://tex.z-dn.net/?f=%5Cepsilon%20%3D-%20%5Cfrac%7B-0.12%7D%7B0.0024%7D%20%3D%2050%20%5BV%5D)
Part B)
When looked down from above, the current flows counter clockwise, according to the right hand rule, if you place your thumb upwards (the direction of the magnetic field) and close your fingers, then the current will flow in the direction of your fingers.
The motion of planets is separate to the motion of stars. Like everything in the sky, they rise in the east, and set in the west, because of the earth's rotation. But night by night, their position at a given time changes because of their orbit around the sun.
Answer:
40sec
Explanation:
Data
Work = 440 J
Power= 11watt
time = ?
Power = work done/time
===> time = work done/power
= 440/11
= 40sec
