Answer:geolocation because that is coldest
Explanation:
Electrical Energy is converted to Kinetic Energy.
Differential Stress are known to be actions that squeeze or push on a rock are stronger in some directions than others.
<h3>What is Differential Stress?</h3>
Differential stress is known to be a kind of difference that do exist between the greatest and the least compressive stress that is experienced by a specific object.
The term is used in geological and civil engineering and it is known to be the greatest compressive stress as Differential Stress are known to be actions that squeeze or push on a rock are stronger in some directions than others.

Answer:
The final temperature in the vessel after the resistor has been operating for 30 min is 111.67°C
Explanation:
given information:
mass, m = 3 kg
initial temperature, T₁ = 40°C
current, I = 10 A
voltage, V = 50 V
time, t = 30 min = 1800 s
Heat for the system because of the resistance is
Q = V I t
where
V = voltage (V)
I = current (A)
t = time (s)
Q = heat transfer to the system (J)
so,
Q = V x I x t
= 50 x 10 x 1800
= 900000
= 9 x 10⁵ J
the heat transfer in the closed system is
Q = ΔU + W
where
U = internal energy
W = work done by the system
thus,
Q = ΔU + W
9 x 10⁵ = ΔU + 0, W = 0 because the tank is a well-insulated and rigid.
ΔU = 9 x 10⁵ J = 900 kJ
then, the energy change in the system is
ΔU = m c ΔT
ΔT = ΔU / m c, c = 4.186 J/g°C
= 900 / (3 x 4.186)
= 71.67°C
so,the final temperature (T₂)
ΔT = T₂ - T₁
T₂ = ΔT + T₁
= 71.67°C + 40°C
= 111.67°C
