Answer:
Option A
Multiplanar step-up to balance
Explanation:
Resistance training exercises are the exercises that cause the muscles to contract against an external resistance leading to an increase in strength and endurance. Resistance training increases muscle strength by making your muscles work against a weight or force.

Answer:
The instantaneous speed of the object after the first five seconds is 12.5 m/s.
(C) is correct option.
Explanation:
Given that,
An object starts at rest. Its acceleration over 30 seconds.
We need to calculate the instantaneous speed of the object after the first five seconds
We know that,
Area under the acceleration -time graph gives speed.
According to figure,
Hence, The instantaneous speed of the object after the first five seconds is 12.5 m/s.
