Where does the material for new mountain ranges come from

Answers

Answer 1
Answer: In the formation of mountain ranges and all other landforms, there is always a cycle involved. As one mountain comes up, another land gets pushed down into the hot mantle, where the rock will melt. Due to convection currents, the tectonic plates move and their boundaries cause them to interact with each other. As mountain ranges are formed, other land gets pushed up forming what we know are mountains, with rising magma from other parts of the world solidifying creating new rock to fill the empty space.

A weight is connected to a spring that is suspended vertically from the ceiling. If the weight is displaced downward from its equilibrium position and released, it will oscillate up and down.If air resistance is neglected, will the total mechanical energy of the system (weight plus Earth plus spring) be conserved?

A. Yes
B. No

Answers

Answer:

Yes

Explanation:

Neglecting air resistance, the total mechanical energy of the system would be conserved because the two forces acting on the weight are the spring force and the gravitational force, and both are conservative in nature.

What is electrical energy?

Electrical energy is the power an atom's charged particles have to cause an action or move an object. The movement of electrons from one atom to another is what results in electrical energy.

There is a dissipation of electrical energy in the resistor when an electric current flows through it. It depends on the resistance of the resistor and the applied voltage.

The expression of the power dissipation is as follows ;

P=(V^2)/(R)

V is the applied voltage.

R is the resistance.

Given

P  = 60 W

30days * 24h/day = 720 Hours kW * h

Therefore by putting the values in the given formula,

= (60/1000)kW * 720h

= 43.2 kWh

Hence,

The cost is  42.2 kWh42.2 kWh x 0.1

= 4.22 dollars

Which statement explains why a blue house looks blue?The house reflects mostly red and green light
The house absorbs mostly blue light
The house reflects mostly blue light
The house reflects every color expect blue

Answers

Answer: The house reflects mostly blue light.

Explanation: The color of an object as seen by our eyes is determined by the color of the light that they reflect.

In case of a blue painted house, all the other colors of white light ( which is a combination of multiple colors) falling on the house are absorbed and only the blue colored light gets reflected back. Hence the house appears to be blue to our eyes.
The house reflects mostly blue light

A rigid, 2.50 L bottle contains 0.458 mol He. The pressure of the gas inside the bottle is 1.83 atm. If 0.713 mol Ar is added to the bottle and the pressure increases to 2.05 atm, what is the change in temperature of the gas mixture?The initial temperature of the gas is ______ K.

Answers

These are inert gases, so we can assume they don't react with one another. Because the two gases are also subject to all the same conditions, we can pretend there's only "one" gas, of which we have 0.458+0.713=1.171 moles total. Now we can use PV=nRT to solve for what we want.

The initial temperature and the change in temperature. You can find the initial temperature easily using PV=nRT and the information provided in the question (before Ar is added) and solving for T.

You can use PV=nRT again after Ar is added to solve for T, which will give you the final temperature. The difference between the initial and final temperatures is the change. When you're solving just be careful with the units!
 
SIDE NOTE: If you want to solve for change in temperature right away, you can do it in one step. Rearrange both PV=nRT equations to solve for T, then subtract the first (initial, i) from the second (final, f):

PiVi=niRTi --> Ti=(PiVi)/(niR)
 
PfVf=nfRTf --> Tf=(PfVf)/(nfR)

ΔT=Tf-Ti=(PfVf)/(nfR)-(PiVi)/(niR)=(V/R)(Pf/nf-Pi/ni)

In that last step I just made it easier by factoring out the V/R since V and R are the same for the initial and final conditions.
