Answer:
Part of the question is missing but here is the equation for the function;
Consider the equation v = (1/3)zxt2. The dimensions of the variables v, x, and t are [L/T], [L], and [T] respectively.
Answer = The dimension for z = 1/T3 i.e 1/ T - raised to power 3
Explanation:
What is applied is the principle of dimensional homogenuity
From the equation V = (1/3)zxt2.
- V has a dimension of [L/T]
- t has a dimension of [T]
- from the equation, make z the subject of the relation
- z = v/xt2 where 1/3 is treated as a constant
- Substituting into the equation for z
- z = L/T / L x T2
- the dimension for z = 1/T3 i.e 1/ T - raised to power 3
Answer:
Change in potential energy is 700.7 J.
Explanation:
Given:
Mass of the object is, 
kg
Height to which the object is raised above his head, 
m
Acceleration due to gravity is, 
m/s²
We know that for a mass 
raised to a height 
, the change in potential energy is given as:
, where, 
Now, plug in the given values and solve.
Therefore, the change in the potential energy is 700.7 J.
