A wagon has a mass of 100 grams and an
acceleration of 2m/s/s. What is the force on the
wagon?

A.) 25N
B.) 200N
C.) 50N
D.) 400N

Net force on the wagon is 200 N

Explanation:

As we know by Newton's II law that net force on the system of mass is given as product of mass and acceleration

Here we know that

mass = 100 kg

a = 2 m/s/s

now we have

graph slopes whilst gas cools, then it is flat whilst conensation to liquid happens, the coolong liquid then graphs as a slope when it solidifies graph is flat

latent heat

vapour or gas assuming atmospheriv pressure
