Mass always stays the same therefore it can’t be c and d. Volume stays the same because she is not removing anything. Therefore it is a
The intensity of a sound wave is defined as the amount of energy passing through a unit area of the wave front in unit of time.
terminal velocity ... greater speed ... acc is 10m/s/s
You should trust the primary source more.
This is because the primary source is make its conclusion from direct observation, while the secondary source is possibly making reference to another secondary source or to another primary.
The primary source should be trusted more because it is from direct observation.
Answer:
Acceleration = 9 × 10^5 m/s^2 ( deceleration )
Explanation:
From the first equation of motion:
V = u + at
15000 = 30000 + 60a
a = ( 15000-30000)/60
a = 9 × 10^5 m/s^2
