Answer:
Friction can be increased the longer two objects are rubbed together, since the longer they are rubbed is the more heat produced.
Explanation:
Answer: The correlation between all of these examples would be They are all earths natural energy balance. To maintain a constant global average temperature, all of the sun’s radiation that enters Earth’s atmosphere must eventually be sent back to space. The greenhouse effect plays a significant role in Earth's energy budget. With the natural greenhouse effect, the energy budget is balanced as thermal radiation is re-radiated towards the ground, trapping thermal energy and warming the Earth. However, with the greenhouse effect being enhanced by humans, the energy budget of the Earth is shifted to an imbalance. It is important to understand that a certain amount of energy being retained due to the greenhouse effect is necessary, but too much results in conditions that account for increased global temperatures and climate change.
Explanation:
In this area the convection is taking place inside the water which is inside the utensils.
<u>Explanation:</u>
- Convection is the type of heat transfer method which is usually taking place through the liquid and gases. In this convection process, the liquid acts as the medium for the heat transfer.
- From the given picture we can see both convection and conduction. The conduction process which occurs in the solid objects. Here the heat is directly given to the pan which is a solid conductor so the pan conducts the heat.
- Inside the pan there happens to be the liquid which favors the convection process and again the eggs are heated by the conduction process as the outer part of the egg is solid.
Answer:
132.22 N
Explanation:
Weight at the surface of a planet is:
W = GMm / r²
where G is the gravitational constant,
M is the mass of the planet,
m is the mass of the object,
and r is the radius of the planet.
On Earth:
680 N = GMm / r²
If Earth's mass and radius were changed:
W = G (7M) m / (6r)²
W = 7/36 GMm / r²
W = 7/36 (680 N)
W = 132.22 N
