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.

HELP PLEASE!!!!

azamat

Answer:

read a pleasant story to him Because if you threaten him meaning abusing him then you could go to jail for that if you read him a pleasant story to him then he will go to bed faster if you play an activity game he'll stay up longer and if you watch an exciting TV show he'll stay up longer too soon you just want him to go to bed sleep peacefully and that's why you read him a pleasant story So yeah my answer is read a pleasant story to him so he can go to bed and not be threatened or play an activity game or watch an exciting TV show if you want them to go to sleep That is why I put read a pleasant story to him

Bridget is riding her bicycle up a hill. Which statements are correct? Check all that apply.

Svetlanka [38]

Answer:

Bridget is transferring energy to the bicycle.

The bicycle is using energy to do work.

Bridget has kinetic energy.

The bicycle has potential energy.

The bicycle has mechanical energy.

Explanation:

Energy can be transformed from one form to another. A body possess kinetic energy due to virtue of its motion. Potential energy is possessed by a body due to virtue of its position. mechanical energy is the sum of potential energy and kinetic energy. Nuclear energy is produced when atoms split or two atoms fuse together.

When Bridget is riding bicycle up a hill. Energy involved is both kinetic energy due to motion and potential energy due to gain in height up the hill. Bridget is pedaling, hence he is transferring energy to the bicycle. Bridget is in motion along with the bicycle. Hence, both Bridget and Bicycle have kinetic energy and potential energy. We can say both have mechanical energy. Thus correct options are:

Bridget is transferring energy to the bicycle.

The bicycle is using energy to do work.

Bridget has kinetic energy.

The bicycle has potential energy.

The bicycle has mechanical energy.

2. Above right: The four positions of the thrown ball with no gravity are

padilas [110]

The characteristics of the projectile launch allows to find the results for the questions about the movement of the ball are:

In the attached we see the vertical speed decreases with height and the curve is of the parabolic type.

In the movement is several dimensions, each one is independent of the others, the movement in the x axis does not affect the movement in the y axis.

Kinematics studies the motion of bodies looking for relationships between position, velocity and acceleration. In the case of vertical and projectiles launch the acceleration on the vertical axis is the acceleration of gravity directed downward.

In the attachment we can see the position of the ball for two distances in the case of projectile launching.

We can see that the speed of the ball decreases with height according to the relation

y = go t - ½ g t²

Where y is the height, g is the initial vertical velocity, g is the acceleration of gravity and t is time.

In all movements in various dimensions we assume that each movement in an . axis is independent

In the case of projectile launching, on the vertical axis there is an acceleration of gravity and on the horizontal axis there is no acceleration, the only parameter that this gives the two movements is the time, which is a scalar.

In conclusion, using the characteristics of the projectile launch, we can find the results for the questions about the movement of the ball are:

In the movement is several dimensions, each one is independent of the others, the movement in the x axis does not affect the movement in the y axis.

In the attached we see the vertical speed decreases with height and the curve is of the parabolic type.

A 1-kg rock is suspended from the tip of a horizontal meterstick at the 0-cm mark so that the meterstick barely balances like a

tigry1 [53]

Explanation:

Given that,

Mass if the rock, m = 1 kg

It is suspended from the tip of a horizontal meter stick at the 0-cm mark so that the meter stick barely balances like a seesaw when its fulcrum is at the 12.5-cm mark.

We need to find the mass of the meter stick. The force acting by the stone is

F = 1 × 9.8 = 9.8 N

Let W be the weight of the meter stick. If the net torque is zero on the stick then the stick does not move and it remains in equilibrium condition. So, taking torque about the pivot.

$9.8\times 12.5=W\times (50-12.5)\\\\W=\dfrac{9.8\times 12.5}{37.5}$

W = 3.266 N

The mass of the meters stick is :

$m=\dfrac{W}{g}\\\\m=\dfrac{3.266}{9.81}\\\\m=0.333\ kg$

So, the mass of the meter stick is 0.333 kg.
