Answer:

option C

Explanation:

The correct answer is option C                        

There is no external force acting in the system hence the momentum will be conserved.                                    

As the milk is leaking out of the tank mass of the tanker is decreasing.

When the mass of the container will decrease to  conservation the momentum speed of the container will have to be increased.

So, the car carrying milk will speed up.

Eric has a mass of 80 kgkg. He is standing on a scale in an elevator that is accelerating downward at 1.7 m/s2m/s2. What is the
kolezko [41]

Answer:

The answer will be 936 N.

Explanation:

Given that

m = 80 kg

Acceleration of the elevator , a= 1.7 m/s²  ( upward)

The gravity force on the mass = m g

The reading on the scale = F N

Now by applying the Newton's second law

F - m g = ma

F= m g + m a

F= m ( g +a )

F= 80 ( 10 + 1.7 ) N                                  ( take g= 10 m/s²)

F=80 x 11.7 N

F= 936 N

Therefore the reading on the scale will be 936 N.

The answer will be 936 N.
