I’m trying to get things expanded graph explanation sorry
Answer:
Different star constellations are visible from Earth at different seasons of the year.
Explanation:
The reason the fact that we can see different constellations in the sky during different seasons on earth is the most compelling reason we travel around the sun is because if the sun travelled around the earth, certain constellations would only be visible in certain places. You’d have to travel to see certain ones.
However, you don’t have to do that because we travel around the sun, therefore travelling around other stars too.
Answer:
V=2.8 ml
Explanation:
volume of the cube is it would be 20.3 - 17.5 ml so 2.8 ml.
Nearly 14 billion years, according to astronomers. Happy to help!
Answer:
When he weight of the car is 8.55 x 
N then power = 314.012 KW
When he weight of the car is 1.10 x 
N then power = 43.76 KW
Explanation:
Given that
Initial velocity 
= 0
Final velocity 
= 24.8 
Time = 7.88 sec
We know that power required to accelerate the car is given by
P = 
Change in kinetic energy Δ K.E = 
Since Initial velocity = 0
⇒ Δ K.E = 
⇒ Power P = 
⇒ Power P = 
-------- (1)
(a). The weight of the car is 8.55 x N = 8550 N
Put all the values in above formula
So power P = 
P = 314.012 KW
(b). The weight of the car is 1.10 x N = 11000 N
Put all the values in equation (1) we get
P = 
P = 43.76 KW
