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. :)
Answer:
Because the weight depends of the gravity
Explanation:
This is because weight and mass are different, in order to better understand this problem we will apply an example with real values, which will help us to determine a person's weight.
A man has a mass of 80 [kg] on Earth when measuring his weight he realizes that it is 784.9 [N] and on the moon it is 130.8 [N]
<u>On Earth</u>
<u />
![g_{e} = 9.81[m/s^2]\\g_{m} = 1.635[m/s^2]](https://tex.z-dn.net/?f=g_%7Be%7D%20%3D%209.81%5Bm%2Fs%5E2%5D%5C%5Cg_%7Bm%7D%20%3D%201.635%5Bm%2Fs%5E2%5D)
Where:
g = gravity
<u>Weight on the moon</u>
<u />
Wm = 80 * 1.635
Wm = 130.8[N]
<u>Weight on the earth</u>
<u />
We = 80 * 9.81
We = 784.8[N]
<u />
In this way we can see that the weight depends on the gravity of where the person is located.
Answer:
average speed, accelerated speed
Explanation:
Pace was first moving at 38 km/h which was his average speed but the fastest speed he went was 60 km/h so he accelerated.
The efficiency of the steam engine is 78.9% because the rest of the work input is used to overcome friction.
<h3>What is efficiency of machines?</h3>
Efficiency of a machine expresses the useful work done by a a machine as a percentage.
- Efficiency of a machine = work output/work input × 100 %%
The efficiency of machines are always less than 100% percent due to energy losses due to friction and heat.
For the steam engine:
Work output = 225 J
Work input = 285 J
Efficiency = 225/285 × 100% = 78.9 %
Therefore, the efficiency of the steam engine is 78.9% because the rest of the work input is used to overcome friction.
