I am quite sure that when a comet comes flying down to eart little chunks began to just come off or float away and meteoroids go where you can see it and meteors hit the ground

why can a thick atmosphere can help protect a planet from meteors

The atmosphere is created from a bunch of gases, it is held in place by the gravity, the friction of the atmosphere will cause the meteor to burn up before it even gets a chance to come in to view.

Which source of energy do refrigeration systems and heat pumps have in common? air ground water sunlight


A) Air


In refrigerator system the compressor will compress the gas at high pressure so that its temperature is too small and if is passed through the air inside the refrigerator.

When this low temperature gas is passed through the air inside the refrigerator then it will extract the heat from the space or air at high temperature and hence it is the source of energy inside the refrigerator.

Heat pumps are used in in cold atmosphere where we require thermal energy to keep the temperature high. Here compressor will work on the gas so that it will absorb the heat from surrounding air and release it to the room or inside space.

So here in both cases the source of energy here is Air which will give heat to the system.

A source of sound is kept in a jar in a vacuum .Air is slowly introduced to the jar . what happened to the sound coming out of the jar


The intensity of the sound increases


Sound is a mechanical wave, that is produced by the oscillations of the particles in a medium. In this case, for example, sound is produced by the vibrations of the air particles.

At the beginning, since there is no air in the jar, no sound is produced, because there are no air particles that can vibrate, to transmit the sound. As air is slowly introduced to the jar, the sound intensity starts to increase. More specifically, the sound gets louder as more air is introduced in the jar. This is because the sound intensity depends on the air density: the greater the density, the more the air particles are, so we have a larger number of vibrations and so the sound gets louder.

If E1 = 13.0 V and E2 = 5.0 V , calculate the current I2 flowing in emf source E2.

The solution would be like this for this specific problem:

KCL at Junction a. 

+ I1 + I2 + I3 = 0 (1) 

+ 13 V - 0.2 R I1 - 0.025 R I1 - 5 V + 0.02 R I2 = 0 (2) 
8 + 0.02 I2 = 0.225 I1 
I1 = 35.6 + 0.0889 I2 (2A) 


KVL (bottom loop - CCW direction) 
- 0.02 R I2 + 5 V + 0.5 R I3 = 0 (3) 
0.5 I3 = -5 + 0.02 I2 
I3 = -10 + 0.04 I2 (3A) 


Replace 2A and 3A into 1. 

+ I1 + I2 + I3 = 0 
( 35.6 + 0.0889 I2 ) + I2 + ( -10 + 0.04 I2 ) = 0 
1.129 I2 = -25.6 
I2 = -22.6A 

Solve 2A and 3A for other currents. 

I1 = 35.6 + 0.0889 I2 = 35.6 + 0.0889 * -22.6 = 33.5A 
I3 = -10 + 0.04 I2 = -10 + 0.04 * -22.6 = -10.9A

So the answer is letter D.

Describe the characteristics of the water at the mountain source: Speed: Temperature: Oxygen Level: Nutrient Level:

The characteristics of the water at the mountain source will be as follows:

- Speed; the speed will be bigger, and this due to the bigger fall through which the water passes down the mountain's steep slopes.

- Temperature; the temperature will be lower, and this is due to the lesser influence of the sun on the water, both, because of its speed, and because of the shade from the forest (assuming there's a forest on the mountain).

- Oxygen level; the oxygen level will be big, because the water in this part is the purest, and doesn't have debris in it, or it has it very small amounts.

- Nutrient level; the nutrient level will be relatively low, because the water is cold and quick, as well as steep, there isn't a big chance for large nutrition base to form in that part of the stream.

The ultimate source of energy that drives wind power is __________.

So we want to know what is the ultimate source of energy that drives wind power. The Sun is the ultimate source of energy because it heats up the Earth's atmosphere. Since the hotter air has lesser density, it starts to rise up. As it rises up it starts to cool. And as it gets cooler, it's density again rises and it gets heavier and starts to fall down. This is what we notice as wind. So the correct answer is: the Sun.

A source charge generates an electric field of 4286 N/C at a distance of 2.5 m. What is the magnitude of the source charge? 1.2 µC 3.0 µC 1.2 C 3.0 C

Answer : Charge, q=3.0\ \muC

Explanation :

It is given that :

Electric field, E=4286\ N/C

Distance, r=2.5\ m

We know that the electric field at any point is given by :


k is the electrostatic constant.

q is the electric charge

r is the distance.

q=\dfrac{E\times r^2}{k}

q=\dfrac{4286\ N/C\times (2.5\ m)^2}{9\times 10^9\ Nm^2/C^2}

q=0.0000029\ C

q=2.9\ \mu C


q=3.0\ \mu C

The correct option is (b).

Hence, this is the required solution.
