Answer:
The energy that drives this movement is heat within the earth, this heat comes from two main sources which are;
1) residual heat left over from the formation of our planet billions of years ago.
2) The radioactive decay of naturally occurring chemical elements (notably uranium, thorium, and potassium ) in the earth releases energy in the form of heat. These two sources of heat warm Earth’s mantle and cause it to rise and sink, this rising and sinking creates a convectional movement of earth mantle.

Answer:
4 P
Explanation:
V = IR
when they are in series R = 2 r
when they are in parallel R = 1/2 r
so current will increase by a factor of 4 when they are in parallel
and power used will also increase by a factor of 4 to 4 P
Power = IV when I now becomes 4 I power becomes 4 P
Answer:
44.1 m
Explanation:
Consider the displacement being x:
x = (g•t²)/2
x = (9.8•3²)/2
x = (9.8•9)/2
x = 88.2/2
x = 44.1 m
