Answer:
The chemical symbol for sodium carbonate is . The decomposition of sodium carbonate is: The decomposition of sodium bicarbonate, will result in the formation of sodium oxide, and carbon dioxide, . Hence, carbon dioxide, will produce with sodium oxide, on decomposition of
Hope this will help you
No, there isn't. Please consult your doctor if this is the case with yours or someone you know.
Answer:
false statement : b ) For the motion of a cart on an incline plane having a coefficient of kinetic friction of 0.5, the magnitude of the change in kinetic energy equals the magnitude of the change in gravitational potential energy
Explanation:
mechanical energy = potential energy + kinetic energy = constant
differentiating both side
Δ potential energy + Δ kinetic energy = 0
Δ potential energy = - Δ kinetic energy
first statement is true.
Friction is a non conservative force so inter-conversion of potential and kinetic energy is not possible in that case. In case of second option, the correct relation is as follows
change in gravitational potential energy = change in kinetic energy + work done against friction .
So given 2 nd option is incorrect.
In case of no change in gravitational energy , work done is equal to
change in kinetic energy.
