How is energy transfer related to the ozone layer and its temperature?

1 answer:

6 0

Energy is transferred between the earth's surface and the atmosphere via conduction, convection, and radiation. Conduction is the process by which heatenergy is transmitted through contact with neighboring molecules. ... During the day, solar radiation heats the ground, which heats the air next to it by conduction.

After an avalanche, a huge block of stone slid down a mountain and landed in the middle of a road. People in the nearby town had

jeka94

Answer:

Option (C)

Explanation:

From Newton's law of inertia, an object at rest tends to be at rest until there is an external force applied to it.

In the given question, the rock block that fell on the road due to the avalanche contains high mass and high inertia. Due to which the block was not able to move aside. The amount of energy required to push the block aside should be more than the mass of the block. So the block has high inertia value and it will need more force than its inertia value in order to move the block of rock towards the side of the road.

Thus, the correct answer is option (C).

Compare and contrast speed and velocity.

vlabodo [156]

Speed is the time rate of an object moving from one place to another, while velocity is the rate and direction of the object's movement. They are very similar but they don't mean the same thing.

two punds of water vapor at 30 psia fill the 4ft3 left chmaber of a partitioned system. The right chmaber has twice the volume o

tamaranim1 [39]

Answer:

pressure of water will be 49.7 atm

Explanation:

given data

pressure = 30 psi = 2.04 atm

water = 2 pound = 907.18

mole of water vapor = 907.19 /2 = 50.4 mole

volume = 4 ft³ = 113.2 L

temperature = 40 F = 277.59 K

to find out

pressure of water

solution

we will apply here ideal gas condition

that is

PV = nRT .......................1

put here all value and here R = 0.0821 , T temperature and V volume and P pressure and n is no of mole

and we get here temperature

PV = nRT

2.04 × 113.2 = 50.4×0.0821×T

solve it and we get

T = 55.8 K

so we have given right chamber has twice the volume of the left chamber i.e

volume = twice of volume + volume

volume = 2(113.2) + 113.2

volume = 339.6 L

so from equation 1 pressure will be

PV = nRT

P(339.6) = 50.4 × ( 0.0821) × (277.59)

P = 3.3822 atm = 49.7 atm

so pressure of water will be 49.7 atm

A moose runs through the woods and covers 825 m North in 118 s. What is the average velocity of the moose?

weqwewe [10]

Total displacement=825m
Total Time=118s

Average Velocity=Total Displacement/Total Time

$\\ \sf\longmapsto Average\: Velocity=\dfrac{825}{118}$

$\\ \sf\longmapsto Average\:Velocity\approx 8m/s$

I WILL CHOOSE YOU AS THE BRAINIEST PLEASE ANSWER MY QUESTION

Brilliant_brown [7]

Answer:

It's like the Earth pulling on you and keeping you on the ground. That pull is gravity at work. Every object in the universe that has mass exerts a gravitational pull, or force, on every other mass. The size of the pull depends on the masses of the objects.
