Answer:
v = 12.79 m/s
Explanation:
Given that,
The mass of a car, m = 1200 kg
Momentum of the car, p = 15 350 kg-m/s
We need to find the velocity of the car. We know that, the formula for the momentum of an object is given by :
p = mv
Where
v is the velocity of the bject
So,
So, the velocity of the car is 12.79 m/s.
Answer:
A - Sublimation
B - Evaporation
C - Melting
Explanation:
The state of change present in A is Sublimation. Dry Ice is the most common example of Sublimation of everyday life
The state of change present in B is evaporation. Boiling water into water vapor is something that anyone can see.
The state of change present in C is called Melting. Think of Ice melting into a pool of water as the ice heats up.
