Hi, time is independent variable. It's stands alone and isn't change by anything.
Temperature is dependant variable (depends on time)
Taking specific heat of lead as 0.128 J/gK = c
We have energy of ball at 7.00 meter height = mgh = 
When leads gets heated by a temperature ΔT energy needed = mcΔT
=
ΔT
Comparing both the equations
=
ΔT
ΔT = 0.536 K
Change in temperature same in degree and kelvin scale
So ΔT = 0.536 
The acceleration is the correct answer
If you try to fit the edges of both continents than they should somewhat fit each other like puzzle pieces
Answer:
distance= 10 km
displacement= 7.21 km
Explanation:
distance= scalar (only magnitude)
displacement= vector (magnitude & direction)
distance= 6 km+ 4 km
= 10 km
displacement= shortest difference btwn 2 pts=
sqrt( 6^2+4^2)
sqrt(52)
7.21 km
