The boat has a lot of parts that has a necessary part in order for it to move and for it to stop. But as the question above asks, the part where the gasoline and the propane fumes accumulate is in the bilge, which is one of the parts of the boat that is considered to be important.
D. density is your answer because density is an intensive property. By the way is this for FLVS?
Answer:
The speed of the car B after the collision is same as the speed of the car A before collision.
Explanation:
lets take the mass of the car A = m kg
Initial speed of the car A = u m/s
The mass of the car B = m kg
Initial speed of the car A = 0 m/s
The final speed of the car A = 0 m/s
The final speed of the car B = v
There is no any external force on the masses that is why the linear momentum will be conserve.
Initial linear momentum = Final linear momentum
P = mass x velocity
m u + m x 0 = m x 0 + m v
m u + 0 = 0 + m v
m u = m v
v= u
Therefore we can say that ,the speed of the car B after the collision is same as the speed of the car A before collision.
I might be incorrect but I’m pretty confident that all of it is right. I think you’re good.
