Answer:
D, using a spring scale to exert a force on the block. Measure the acceleration of the block and the applied force
Explanation:
For this you would use the net force equation acceleration=net force * mass however you will want to isolate mass so it would be acceleration/ net force to get mass. Then process of elimination comes to play.
Answer:

Explanation:
Velocity can be found using the following formula:

where p is the momentum and m is the mass.
The woman has a mass of 55 kilograms and a momentum of 200 kilogram meters per second.

Substitute the values into the formula.

Divide. Note that the kilograms, or kg, will cancel each other out.


The woman's velocity is 3.63636364 meters per second.
Melting: as mantle material rise toward the divergent plate boundary the pressure is reduced which causes melting
