A. Radioactive decay does not result in heat. Gravity also does not result in heat. In the Earth's mantle, it is highly unlikely that the radiation from the sun would reach that deep into the earth.
Answer:
Magnetic field lines never intersect each other.
They originates(from north pole) and terminates (to south pole) perpendicularly from/to the surface of magnet. Also magnetic field lines continues through the magnet.
Magnetic field is denser at the pole and becomes less dense as we move away from the poles.

Answer:
Explanation:
r=A(1 m/s)t^i+A((1 m/s3)t3−6(1 m/s2)t2)^j,
dr / dt = A i + (3 A t² - 6 x 2 t ) j
At t = 2
dr / dt = A i + (12A - 24 A ) j = A i - 12 A j .
Since slope is negative so velocity is downwards , hence it is descending
b ) velocity = dr / dr = . A i + (3 A t² - 6 x 2 t ) j
Vx = A
Vy = 3A t² - 12 t
We know that
tan(∅) = y/x; where y will be the height of the balloon and x will be the distance from the milestone marker.
The marker that is further away will produce a smaller angle of depression.
tan(18) = height / x
x = height / tan(18)
The second marker is x + 1 miles away:
tan(16) = height / x + 1; substituting x:
tan(16) = height / (height/tan(18) + 1)
tan(16) x [(height / tan(18) + 1] = height
0.88h + 0.29 = h
h = 2.42 miles
