kumpel [21]

Answer:

Graph C

Explanation:

With the same force and more mass, the position in time will still be parabolic

i.e.  x = ½at², but the rate of acceleration will be lower so the position curve will be broader.

Water is contained in a closed, rigid 0.2 m 3 tank at an initial pressure of 5 bar and a quality of 50%. Heat transfer occurs un
elena55 [62]

Answer:

Final mass=0.89kg

Final pressure=5.6bar

Explanation:

To find mass,m=v/v1

But v1=vf + x(vg-vf)

Vf= 0.001093m^3/kg

Vg= 0.3748m^3/kg

V1= 0.001093+0.5(0.3748-0.001093)

V1= 0.225m^3/kg

M= 0.20/0.225 =0.89kg

Final pressure will be:

V/V1= P/P1

Cross multiply

VP1=V1P

P1= 0.225×5/0.2

P1=:5.6 bar

What does Newton's third law describe?<br> What does Newton's third law describe?
defon

Explanation:

<em>Sir Isaac Newton's third law of motion</em> says that every action has an equal and opposite reaction.

For example, when you fire a gun, the gun exerts a force on bullet. Even the bullet exerts an equal force on the gun, causing it to recoil.

The Earth revolves around the Sun as the Sun attracts it. The reason why Earth doesn't fall into it is because the Earth also attracts the Sun with an equal gravitational force.
