The answer for question 2 i guess it’s c
Hand grip test an example of an isometric muscle contraction.
Isometric(increased pressure but no shortening)
Explanation:
- Isometric contraction, is one in which the muscle is activated, but instead of being allowed to lengthen or shorten, it is held at a constant length.
- An isometric exercise is a form of exercise involving the static contraction of a muscle without any visible movement in the angle of the joint.
- Isometric exercises are contractions of a particular muscle or group of muscles. During isometric exercises, the muscle doesn't noticeably change length and the affected joint doesn't move. Isometric exercises help maintain strength. They can also build strength, but not effectively.
- Isometric exercise is also known as static strength training. (Examples include the plank and side bridge as well as the wall sit and many yoga poses such as chair and tree poses).
Answer:
Explanation:
What happens to the total amount of kinetic energy is that as the train of coaster train loses height, they tend to speed up, this makes their potential energy to convert to kinetic energy due to the height, and as the motion continues, there is continuous gaining and losing of height by the object and its speed.
Each time there is a gain in height, there is also a corresponding conversion of kinetic energy to potential energy and while for each loss of height, there is also a corresponding conversion of potential energy to kinetic energy and this is as a result of speed.
This illustrates the relationship between work and energy.
Answer:
9.97sec
Explanation:
To solve for the period we can derive the formula as follows
ω=2πf
ω=2π/T
v=rω
v=2πr/T
T=2πr/v
T=9.97sec
OK think of it distance,The smaller the distance less momentum is needed the Longer the distance the the longer the momentum is needed.
And The Answer Is quite easy their was no reason to be asked
Answer:1.0meter
