Earth houses are predominantly illuminated with natural light. TRUE or FALSE.

Answers

Answer 1

It is true that earth houses are predominantly illuminated with natural light. There aren't many electrical installations in earth houses, which is why people living in these homes mostly rely on natural light to illuminate their rooms. They light their rooms by opening their windows and letting the sunshine enter the house so as to bring them some light since there is no electricity.

Answer 2

Earth houses are predominantly illuminated with natural light. this is TRUE

A 50 g sample of an unknown metal is heated to 90.0C. It is placed in a perfectly insulated container along with 100 g of water at an initial temperature of 20C. After a short time, the temperature of both the metal and water become equal at 25C. The specific heat of water is 4.18 J/gC in this temperature range. What is the specific heat capacity of the metal? Record your answer with two significant figures. J/gC

Answers

Q = mcΔT
Qwater = -Qmetal

(100 g)(4.18 J/g°C)(25°C - 20°C) = -(50 g)c(25°C - 90.0°C)

2090 J = (3250 g °C)c

c = 0.643 J/g °C

The specific heat capacity of the metal, given the data is 0.6 J/gºC

Data obtained From the question

Mass of metal (M) = 50 g
Temperature of metal (T) = 90 °C
Mass of water (Mᵥᵥ) = 100 g
Temperature of water (Tᵥᵥ) = 20 °C
Equilibrium temperature (Tₑ) = 25 °C
Specific heat capacity of the water (Cᵥᵥ) = 4.18 J/gºC
Specific heat capacity of gold (C) =?

How to determine the specific heat capacity of the metal

Heat loss = Heat gain

MC(T –Tₑ) = MᵥᵥC(Tₑ – Tᵥᵥ)

50 × C × (90 – 25) = 100 × 4.18 × (25 – 20)

C × 3250 = 2090

Divide both side by 3250

C = 2090 / 3250

C = 0.6 J/gºC

A ball rolls up a ramp until it stops and turns around. It then rolls back down. At what position is its potential energy the greatest? when it reaches the highest point on the ramp

when it is traveling fast at the bottom of the ramp heading up

as it slows down halfway up the ramp

as it speeds back up, heading back down the ramp

Answers

Potential energy is the energy possessed by an object due to its position relative to a reference line. Potential energy is given as

PE = mgh

where m = mass of the object

g = acceleration due to gravity

h = height from the reference line.

from the formula , we see that potential energy is directly proportional to the height. hence greater the height, larger will be the potential energy.

hence the potential energy is greatest when

when it reaches the highest point on the ramp

When it reaches the highest point on the ramp

The vertical displacement of the wave is measured from the ? equilibrium to the crest and is called the frequency.

crest to the trough and is called the amplitude.

trough to the trough and is called the wavelength.

equilibrium to the crest and is called the amplitude.

Answers

The whole question is talking about the amplitude of a wave
that's transverse and wiggling vertically.

Equilibrium to the crest . . . that's the amplitude.

Crest to trough . . . that's double the amplitude.

Trough to trough . . . How did that get in here ? Yes, that's
   the wavelength, but it has nothing to do
   with vertical displacement.

Frequency . . . that's how many complete waves pass a mark
   on the ground every second. Doesn't belong here.

Notice that this has to be a transverse wave. If it's a longitudinal wave,
like sound or a slinky, then it may not have any displacement at all
across the direction it's moving.

It also has to be a vertically 'polarized' wave. If it's wiggling across
the direction it's traveling BUT it's wiggling side-to-side, then it has
no vertical displacement. It still has an amplitude, but the amplitude
is all horizontal.

the answer is A.

A solid aluminum cube has sides each of length L . A second cube of the same material has sides two times the length of the first cube; i.e., 2 L . Compared to the first cube, what is the density of the second cube?

Answers

Density is a material property, so the second cube will have the same density as the first.

Density is a property of the substance, no matter how much of it you have. A microscopic speck of it and a truckload of the same stuff have the same density.

C. shift to a higher gear
D. adjust your speed to the current road conditions

Answers

The question is asking us what you should do "For safety concerning a curve. The correct answer is that you should : A. decelerate before the curve, this would reduce your speed, and also the time needed to break, so you will have more time to react to the environment and also you would need less time if you see someone on the road and decide to break.
