I’m guessing convection currents since you mention mantle and core, reminds me of heat
Answer:
The period would be 0.0034 seconds
Explanation:
The d string has a frequency of 293 Hz when it is in tune
So the period of D string is 0.0034 seconds
Answer: Option (a) is the correct answer.
Explanation:
When gases, liquids, or solids are in contact with a moving object then friction occurs due to the movement of objects in opposite directions.
During this opposite movement, bonds between the molecules of respective objects break and again their is formation of new bonds.
This breaking or making of bonds results in the formation of energy in the form of heat.
Thus, we can conclude that when gases, liquids, or solids are in contact with a moving object, the flow of heat occurs due to frictional forces.
Answer:
<em>A very high metabolism and a very small size.</em>
<em></em>
Explanation:
The pygmy shrew is a very small mammal, that forages day and night. The metabolism of the Pygmy shrew is so high that it must eat at least every 30 minutes or it might die. The best explanation for what happens to the food's mass and energy is that most of the food mass is rapidly used fro building up of the shrew due to its very high metabolism, and a bigger portion of the food is lost from the surface of the body of the shrew, due to its very small size. The combination of these two factors; a very high metabolism (rapidly uses up food material, and generates a large amount of heat in a very short time) and the very small size (makes heat loss due to surface area to volume ratio high) explains what happens to the food mass and energy.
Answer:
Correct answer: D = 10,800 m = 1.08 · 10⁴ m
Explanation:
None of the answers offered are correct.
The described motion is uniform with constant speed and the formula is:
D = v · t
Given: v = 15 m/s and time t = 12 min = 12 · 60 seconds = 720 seconds
D = 15 · 720 = 10,800 m = 1.08 · 10⁴ m
D = 10,800 m = 1.08 · 10⁴ m
