Explanation:

PE= mgh

6 J= (3m) (9.81 m/s2) (mass)

mass=( 6)/(3×9.81)

mass= 0.20 Kg

As the gas is cooled, it will make a phase transition from gas into liquid, and upon further cooling from liquid to solid (ie. freezing). Some gases, such as carbon dioxide, skip the liquid phase altogether and go directly from gas to solid.

Not really understanding this, wouldn't mind some help. : )
ddd [48]

Explanation:

Given

Mass (m) = 1200 kg

Acceleration (a) = 3 m/s²

Force (F) = ?

We know

F = m * a

= 1200 * 3

= 3600 Newton.

Therefore the force acting on the car is 3600 Newton.

Hope it will help):)

Mary takes 6.0 seconds to run up a flight of stairs that is 102 meters long. If Mary's weight is 87 newtons, what power has Mary
fredd [130]

Answer: 1479watts

Explanation:

Power is defined as the energy expended or work done in a specific time.

Mathematically,

Power = Workdone/time taken

Since work done is force × distance

Power = force × distance/time

Force = Mary's weight = 87N

Distance = height of the flight = 102meters

Time = 6.0seconds

Substituting in the formula we have;

Power = 87 × 102/6

Power = 1,479watts

Note that the time must be in seconds before usage. If its given in minutes, you will have to convert to seconds

When an object is at rest, it might have several forces acting on it. however,?
SSSSS [86.1K]
For the object to be moving, there must be a value for the forces acting on this object in a certain direction to cause the object to move.

On the other hand, when an object is at rest, despite the possibility of having several forces acting on it, these forces balance out to a net force of zero which keeps the body still with no motion.
