Answer:
e. the number of active motor units increases.
Explanation:
There is a direct relationship between the number of active motor units and the grip strength in a given scenario. <em>For example, increase in the grip strength leads to increase in the number of active motor units. In the other-hand, the decrease in grip strength leads to the decrease in the number of active motor units.</em>
Answer:
A) because wave speed remains constant.
Explanation:
The wave speed of a wave in a medium depends on the nature of the medium.
For transverse waves in a string given by,
, T = tension , m = linear density
For longitudinal waves in a solid,
, ξ = modulus of elasticity, ρ = density
Like wise for different media, different properties and parameters govern the speed of waves moving through them.
It is important to mind in v = fλ ,f or λ does not influence on speed of wave in a medium but shows how f and λ varies as a wave propagate in a medium(/media).
Answer:
The answer should be C
Explanation:
An exothermic process releases heat, causing the temperature of the immediate surroundings to rise. An endothermic process absorbs heat and cools the surroundings.

A motion diagram represents the motion of an object by displaying its location at various equally spaced times on the same diagram. Motion diagrams are a pictorial description of an object's motion. They show an object's position and velocity initially, and present several spots in the center of the diagram.
