Answer:
Kinetic energy
Explanation:
Kinetic energy is a function of velocity. Since the rider is moving at a certain speed, he's demonstrating kinetic energy. It can't be potential energy because potential energy encompass mgh
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:
Explanation:
Kinematics equation for constant acceleration:
Answer:
volume
Explanation:
Identical size means volume will be the same in each calculation of
density = mass / <u>volume</u>
Answer:
angular resolution = 0.07270° = 1.269 × 
rad
greatest distance from the camera = 118.20 m = 0.118 km
Explanation:
given data
diameter = 0.50 mm = 0.5 × m
distance apart = 15 cm = 15× 
m
wavelength λ = 520 nm = 520 × 
m
to find out
angular resolution and greatest distance from the camera
solution
first we expression here angular resolution that is
sin θ = 
.......................1
put here value λ is wavelength and d is diameter
we get
sin θ = 
θ = 0.07270° = 1.269 × rad
and
distance from camera is calculate here as
θ = 
.................2
I = 
I = 118.20 m = 0.118 km
