During its lifepsan, the sun's core would keep contracting and heating up.
The temperature will keep increasing to the point where the temperature outside the core will get to hydrogen fusion temperatures.
The sun will grow in surface and eventually became the Red Giant
Answer:
5 kg
Explanation:
PE = KE
mgh = KE
m (9.8 m/s²) (1 m) = 50 J
m = 5.1 kg
Rounded to one significant figure, the mass is 5 kg.
Answer:
The approximate displacement of the object is <u>23 </u>m.
Explanation:
Given that:
v = 4t + 5 (m/s) for 3< t< 7; n= 4
The approximate displacement of the object can be calculated as follows:
The velocities at the intervals of t are :
3
4
5
6
the velocity at the intervals of t = 7 will be left out due the fact that we are calculating the left endpoint Reimann sum
n = 4 since there are 4 values for t, Then there is no need to divide the velocity values
v(3) = 4(3)+5
v(3) = 12+5
v(3) = 17
v(4)= 4(4)+5
v(4) = 16 + 5
v(4) = 21
v(5)= 4(5)+5
v(5) = 20 + 5
v(5) = 25
v(6) = 4(6)+5
v(6) = 24 + 5
v(6) = 29
Using Left end point;
= 23 m

Answer:
The acceleration of a rock thrown straight upward on the way up, at the top of its flight and on the way down is called gravity, and it's denoted by the letter g.
Gravity change vary depending on the position on Earth or the planet that you are studying
Usually on earth we use
Explanation:
<u>If we analyze </u><u>Newton's second law</u>
<u>Then we have the force that is caused by the </u><u>weight</u><u> of the rock</u>
So, we have that
