Answer:

A fluid in stability in a vessel applies pressure energy to the complete fluid, according to Pascal's principle.

Explanation:

Pascal's principal explains that Pressure changes applied to the outer part of an confined fluid are transferred uniformly throughout the fluid.

Pascal's law is a one of the laws in fluid mechanics.

This is given by Pascal. This law explains that a pressure change at any point in a limited close fluid is transferred throughout the fluid such that the same change occurs everywhere.

If you start with a substance as a solid, what will happen to the molecules as you add thermal energy (heat)?

AveGali [126]

Answer:

C. molecules speed up as more thermal energy is added

Explanation:

The molecules will simply speed up as more thermal energy is added to the solid.

Thermal energy is a form of kinetic energy which is set in motion.

Heat causes kinetic energy build up in a body.
As the molecules of the solid gains heat, they will continue to increase in thermal energy.
They are forced to start vibrating about their fixed point.
Thereafter, when they have enough energy, they break free from the forces holding them.
Therefore, they move from a state of rest to one with a very high kinetic energy where the molecules moves rapidly.
This is why a solid will change to liquid and sometimes eventually gas

Earth orbits the sun once every

Karo-lina-s [1.5K]

Answer:1 trip around the earth is an angular displacement of 2*pi

3.6525*10^2 days

Explanation:24 h/1 day * 3.600*10^3 s/1h = 3.156*10^7 s

Angular speed = angular displacement / time

Angular speed = 2*pi rads / 3.156*10^7 s = 1.9910*10^-7 rad/s

the specific heat of water is 4.2 j/c. if it takes 31,500 joules to heat to warm 750 g of water, what was the temperature change

defon

The amount of heat needed to increase the temperature of a substance by $\Delta T$ is given by
$Q=mC_s \Delta T$
where
m is the mass of the substance
$C_s$ the specific heat capacity
$\Delta T$ the increase in temperature

In our problem, the mass of the water is m=750 g, the specific heat is $C_s = 4.2 J/g ^{\circ}C$ and the amount of heat supplied is $Q=31500 J$ , so if we re-arrange the previous formula we find the increase in temperature of the water:
$\Delta T= \frac{Q}{m C_s}= \frac{31500 J}{(750 g)(4.20 J/g^{\circ} C)}=10^{\circ}C$
