s = d/t
Speed = Distance divided by time
It is False that, If f '(c) = 0, then f has a local maximum or minimum at c.
Local maximum and minimum points are very distinctive on the graph of a function and are thus, helpful in grasping the shape of the graph. Either a local minimum or a local maximum can be considered a local extremum.
A counterexample can be used for:
f(x) = x³
f'(x) = 2 × x²
and,
f'(0) = 2×0² = 0
However, the assertion is false because x = 0 is actually an inflection point rather than a maximum or minimum in f(x) = x³.

Answer:
TRUE
Explanation:
When a wire with a current is placed in a magnetic field, electrical energy is transformed into mechanical energy. The transformation happens when the magnetic field produced by the current causes the wire to move.
Answer: Option (A) is the correct answer.
Explanation:
Relation between kinetic energy and temperature is as follows.
As, kinetic energy is directly proportional to temperature. So, when there will be increase in temperature then there will also occur increase in kinetic energy of the particles of a substance.
And, when gas particles move slowly then it means kinetic energy of gas particles is very low. It also implies that temperature is low.
Thus, we can conclude that temperature will increase best describes the outcome of increasing the kinetic energy of the molecules in the above picture.
