Answer:
a loud explosive noise caused by the shock wave from an aircraft traveling faster than the speed of sound.
Explanation:
Answer:
1) 0.51 seconds.
2) 1.45 m/s.
Explanation:
given, height from which cat falls = 1.3 m
we know that, s = ut + 
at².
here if we consider cat moment only in downward direction,
intial velocity of cat in downward direction , u = 0.
so, time, t = 
.
⇒ t = 
= 0.51 seconds.
t = 0.51 seconds.
now, consider cat moment only in forward direction
s = ut , since acceleration is zero in forward direction
⇒ u = 
.
so, u = 
= 1.45 m/s .

I gotchu, the answer’s elastic potential energy.
Answer:
2. much hotter and much denser than its surface
Explanation:
We know that the temperature around the center of the Sun is about 1.57×10⁷ K and its density is about 162 g/cm³.
Now, the temperature and the density decrease as one moves outward from the center of the Sun, the temperature at the surface of the sun is about 5×10³ K and the density as an average in the surface is about 1.4 g/cm³.
Therefore the answer is:
2. much hotter and much denser than its surface.
I hope it helps you!
Have a nice day!
