The first question would be A
The second would be either A or D
Intensity, E follows inverse square law.
E α 1/r²
r is the distance.
So if the distance r is increased by 3, the intensity would be reduced by 3²
3² = 9
So the answer is nines times as low. C.
AnswerIt is continuously falling towards the surface of the earth
Explanation:
since gravity from earth is the thing that keeps it constantly in orbit
Answer:
Because the angle of the sun moves/rotates in the summer, the sun's rays move their angle and impact the earth.
The right answer for the question that is being asked and shown above is that:
B.
Property Electromagnet Magnet
Permanent magnet X
Temporary magnet X X
Magnetic field created by aligning domains X
<span>Moving electric charge produces magnetic field X</span>
