Answer:
FALSE
Explanation:
Temperature inversion usually refers to the situation where a warm air lies over a cooler air that is present from the surface of the earth up to a certain height.
Normally, the temperature increases with increasing height. But, in the case of temperature inversion, the reverse of it takes place. This layer of inversion may occur at any place within the level of the troposphere.
This temperature inversion obstructs the atmospheric flow due to which the air mass present over a particular area become stable, resulting in a number of weather patterns.
On the other hand, greenhouse gases are those gases that can hold the incoming solar energy and radiate back into the atmosphere, thereby resulting in an increase in temperature of the atmosphere. Example, CO₂, CFC, H₂O and CH₄.
Hence, the above-given statement is false.
Answer: Stars
Explanation: Some stars have remained intact since the Big Bang. These stars are shown in something called the HR diagram with portrays the brightness and largeness of the star. Also, white dwarfs and black dwarfs can be traced back which may correspond with the initiation of the universe.
Momentum = mass x velocity
So both mass and velocity affect an object's momentum.
1110 atm
Let's start by calculating how many cm deep is 36,000 feet.
36000 ft * 12 in/ft * 2.54 cm/in = 1097280 cm
Now calculate how much a column of water 1 cm square and that tall would mass.
1097280 cm * 1.04 g/cm^3 = 1141171.2 g/cm^2
We now have a number using g/cm^2 as it's unit and we desire a unit of Pascals ( kg/(m*s^2) ).
It's pretty obvious how to convert from g to kg. But going from cm^2 to m is problematical. Additionally, the s^2 value is also a problem since nothing in the value has seconds as an unit. This indicates that a value has been omitted. We need something with a s^2 term and an additional length term. And what pops into mind is gravitational acceleration which is m/s^2. So let's multiply that in after getting that cm^2 term into m^2 and the g term into kg.
1141171.2 g/cm^2 / 1000 g/kg * 100 cm/m * 100 cm/m = 11411712 kg/m^2
11411712 kg/m^2 * 9.8 m/s^2 = 111834777.6 kg/(m*s^2) = 111834777.6 Pascals
Now to convert to atm
111834777.6 Pa / 1.01x10^5 Pa/atm = 1107.2750 atm
Now we gotta add in the 1 atm that the atmosphere actually provides (but if you look closely, you'll realize that it won't affect the final result).
1107.274 atm + 1 atm = 1108.274 atm
And finally, round to 3 significant figures since that's the accuracy of our data, giving 1110 atm.
Answer:
A) A warm wire
Explanation:
A warm wire has the most resistance. Heating the metal wire causes atoms to vibrate more, which in turn makes it more difficult for the electrons to flow, increasing resistance. Heating the wire increases resistivity.
