Answer:
52 N
Explanation:
Given:
Work done= 1820 J, distance= 35 meters Force = ?
Formula for work done
W = F • d
Find F.
F = W / d
Substitute the given into the equation.
F = 1820 J / 35 m
= 52 N
Recall the equation relating an object's change in thermal energy to its change in temperature:
ΔQ = mcΔT
ΔQ is the change in thermal energy.
m is the mass of the object.
c is the object's specific heat.
ΔT is the object's change in temperature.
Given values:
m = 0.5 kg = 500g
ΔT = (7-0)⁰C = 7°C
Online sources say the specific heat of silver is 0.240 J/g⁰C
Substitute the terms in the equation with the given values and solve for ΔQ:
ΔQ = 500×0.240×7
<h3>ΔQ = 840 J</h3>
A)conversion I think, it is if I'm wrong, sorry
Because the core is the hottest place at which it holds the most heat to bring it out to be towards africa.
