Answer:
The term used when one objects heat transfers to another would be known as: Convection.
Explanation:
Convection: <em>"the movement caused within a fluid by the tendency of hotter and therefore less dense material to rise, and colder, denser material to sink under the influence of gravity, which consequently results in transfer of heat."</em>
The article I skimmed over explains, <em>"The outside surface of the cup is obviously hot or warm to the touch. Heat is not carried away fast enough from the cup to make the temperature of the outside surface of the cup equal to room temperature. Clearly, the cooling of the hot water in the cup involves conduction of heat through the cup followed by convection of the hot air associated with the outside surface of the cup away from the surface of the cup."</em>
In short, when a warm or cold liquid in a glass is set onto a table (the table is room temperature), then the temperature of that liquid will transfer into the table, causing the liquid to be room temperature after a certain time.
I hope this makes sense to you! Have a great rest of your night!

Answer:
the speed acquired by the man is:
Explanation:
Use conservation of linear momentum to solve this problem, and make sure you start by converting the 63 g stone mass into kilograms = 0.063 kg.
Now from conservation of linear momentum, the momentum imparted to the stone (which is the product of the stone's mass time its speed) must equal in magnitude that of the 90 kg man. Then we need to find the unknown speed of the man:
therefore the speed acquired by the man is:
Answer:
a) x = (0.0114 ± 0.0001) in
, b) the number of decks is 5
Explanation:
a) The thickness of the deck of cards (d) is measured and the thickness of a card (x) is calculated
x = d / 52
x = 0.590 / 52
x = 0.011346 in
Let's look for uncertainty
Δx = dx /dd Δd
Δx = 1/52 Δd
Δx = 1/52 0.005
Δx = 0.0001 in
The result of the calculation is
x = (0.0114 ± 0.0001) in
b) You want to reduce the error to Δx = 0.00002, the number of cards to be measured is
#_cards = n 52
The formula for thickness is
x = d / n 52
Uncertainty
Δx = 1 / n 52 Δd
n = 1/52 Δd / Δx
n = 1/52 0.005 / 0.00002
n = 4.8
Since the number of decks must be an integer the number of decks is 5
