The solar interior includes the core, radiative zone and convective zone. The photosphere is the visible surface of the Sun.
So the answers should be:
<u>A) Photosphere C) Core D) Radioactive zone </u>and<u> F) Convective zone.</u>
I hope this helps. Sorry if I made any mistakes. :)
The acceleration of the crate is 1.196 m/s².
<h3>What is acceleration?</h3>
This can be defined as the rate of change of velocity.
To calculate the acceleration of the crate, we use the formula below.
Formula:
- a = (F-mgμ)/m................. Equation 1
Where:
- a = acceleration of the crate
- m = mass of the crate
- F = Force applied to the crate
- μ = Coefficient of friction
From the question,
Given:
- m = 225 kg
- F = 710 N
- g = 9.8 m/s²
- μ = 0.20
Substitute the values above into equation 1
- a = [710-(225×9.8×0.20)]/225
- a = (710-441)/225
- a = 269/225
- a = 1.196 m/s²
Hence, The acceleration of the crate is 1.196 m/s²

Answer:
Overproduction can lead to other side effects, which can be considered an advantage or a disadvantage. When more offspring are produced, it increases the odds of a spontaneous variation.
Work needed = 23,520 J
<h3>
Further explanation
</h3>
Given
height = 12 m
mass = 200 kg
Required
work needed by the crane
Solution
Work is the transfer of energy caused by the force acting on a moving object
Work is the product of force with the displacement of objects.
Can be formulated
W = F x d
W = Work, J, Nm
F = Force, N
d = distance, m
F = m x g
Input the value :
W = mgd
W = 200 kg x 9.8 m/s²x12 m
W = 23520 J
