The first option.
The total mechanical energy before an action (which makes up PE and KE) equals the total mechanical energy after an action.
So
KEi + PEi = KEf + PEf
At normal temperature,
specific heat of air = 1.006
concrete =0.96
water =4.187 (all are in KJ/KgK)
soil = 0.80
So, from <span>Q=mcDeltaT</span><span>
higher the specific heat lower the change in temperature for same quantity of heat supplied.
Therefore, water is the answer.</span>
A. The commander in chief role deals only with the the military, while the chief executive role is broader
Answer:
The magnitude of the angular acceleration is α = (3 * F)/(M * L)
Explanation:
using the equation of torque to the bar on the pivot, we have to:
τ = I * α, where
I = moment of inertia
α = angular acceleration
τ = torque
The moment of inertia is equal to:
I = (M * L^2)/3
Also torque is equal to:
τ = F * L
Replacing:
I * α = F * L
α = (F * L)/I = (F * L)/((M * L^2)/3) = (3 * F)/(M * L)
The answer is A temperate zones
