Explanation:
Heat = mc(change in temp.)
m=mass , c = specific heat
Rate of flow of heat = heat current = kA/L(T2-T1)
So, mass = density×volume
So, mc(T2-T1)/time =
kA/L(T2-T1)
Substitute the values given as there are a lot of values missing, so the answer can not be obtained.
Answer:
Torque will be equal to 4.176 N-m
Explanation:
It is given moment of inertia about knee joint 
Angular acceleration produced 
We e have to find the torque
Torque is equal to 
, here I is moment of inertia and 
is angular acceleration.
Torque will be equal to 
So torque is equal to 4.176 N-m
Hello,
The answer is B) <span>electrical to mechanical.

(NH4)2CO3(s) ⇄ 2NH3(g) + CO2(g) + H2O (g)
The effect that adding water (H2O) have in reaction above is that The concentration of the product would decrease, and the concentration of reactant would increase. (answer C)
<u><em>Explanation</em></u>
- If the concentration of one substance is changed, the equilibrium shift to minimize the effect of that change.
- H2O in reaction above is a product.
- Increase of water (H2O) concentration will led to the shift of equilibrium to the left ( reactant side) .The concentration of reactant increase as that of product decrease.
