Answer:
decreases.
Explanation:
When the aircraft is flies from the warm air into the colder air then its speed will be decreases.
as we know that
we know mach number is constant
so that here Mach number M is expressed as
M = .............................1
here u is Local flow velocity with respect to the boundarie and v is the speed of sound in the medium
If the aircraft flies from hot air to cold air, the speed of sound in the medium will decrease. But the Mach number remains constant. Therefore, the local flow velocity relative to the boundaries also decreases.
Answer:
a.
Explanation:
Remeber speed and velocity are the same concept, it just speed is scalar, meaning it doesn't have a direction nor it negative.
So technically thr car had a constant speed over 75 seconds.
If thr car has a constant speed, the car isn't speeding up or slowing down so it has accleration of 0 so the answer is a.
1. Naturally occurring
2. Inorganic
3. Crystalline structure
4. DEFinite chemical composion
5. Solid
