Answer:
Diathermy and atmospheric pressure
Explanation:
When the energy from the Sun comes to the Earth, it hits first the atmosphere, but the air contained is almost unaffected by it because the molecules are not tight enough to absorb its incoming energy.
Later on, the sunlight reaches the soil, thus absorbing part of the energy and reflecting the rest. Because of this reflection, the air near to the ground begins to heat through convection and as it gains height the air pressure (thus the air molecules begin to separate more from each other) decreases and the energy transfer to them is more difficult. As a result, as you gain height, the air temperature decreases at a rate of 6.8 ºC every 1,000 meters.
Answer:
Average Velocity = - 1.22 cm/s = - 0.0122 m/s
Explanation:
The average velocity of an object is defined as the ratio of the total distance traveled by the object to the total time taken by the object to cover the distance. Therefore, the average velocity of an object can be found by the following formula:
Average Velocity = Total Distance Covered/Total Time Taken
Average Velocity = (Final Position - Initial Position)/Total Time Taken
Average Velocity = (3.7 cm - 6.5 cm)/(2.3 s)
Average Velocity = (- 2.8 cm)/(2.3 s)
<u>Average Velocity = - 1.22 cm/s = - 0.0122 m/s</u>
here, the negative sign indicates the direction of the velocity or the movement of the object is leftwards or towards the origin approaching from right.
The total work done is equal to 134 J.
<h3>Work</h3>
The work formula is characterized as the multiplication of the force performed and the distance in which the movement was performed, so that:
Thus, it is enough to calculate the value of the work in each movement and add to find the total work, so that:
So, the total work done is equal to 134 J.
