Answer:
It is centripetal force i think hope it helps:)
Explanation:
Answer:
t=0 is t
t=8= 8t
Explanation:
because 0 is means "nothing" so that's why t=0 is t
Answer:
D. Friction
Explanation:
"Friction is caused by microwelds that form between two surfaces. Microwelds are stronger when the two surfaces are pushed together with a greater force." - ( Module 3 • Forces and Newton’s Laws) quoted
hope this helps and is right. p.s. i really need brainliest :)
Answer:
20°C
Explanation:
Heat gained by the colder water = heat lost by the warmer water
m₁ C (T − T₁) = m₂ C (T₂ − T)
m₁ (T − T₁) = m₂ (T₂ − T)
(500) (T − 10) = (100) (70 − T)
5 (T − 10) = 70 − T
5T − 50 = 70 − T
6T = 120
T = 20
The final temperature is 20°C.
Answer:
Gay-Lussac’s law, because as the pressure increases, the temperature increases
Explanation:
First of all, we can notice that the volume of the tank is fixed: this means that the volume of the air inside is also fixed.
This means that in this situation we can apply Gay-Lussac's law, which states that:
"for a gas kept at constant volume, the pressure of the gas is proportional to the absolute temperature of the gas".
Mathematically:
where p is the pressure in Pascal and T is the temperature in Kelvin.
In this case, the tank is filled with air: this means that the pressure of the gas inside the tank increases. And therefore, according to Gay-Lussac's law, the temperature will increase proportionally, and this explains why the tank gets hot.
