Answer:
Explanation:
The planet in the orbit with the largest major axis takes the longest
to complete one orbital revolution.
Since for closed system moles of the gas is always conserved
so as per idea gas equation we can say
so here we can say
so here we have
as we know that
now from above equation
on solving above equation we have
so here pressure will be 0.78 atm
Based on the combined form of the ideal gas law, the final pressure of the gas, given the changes in volume and temperature, would be approximately 0.725 atm.
The question concerns the change in conditions of a gas and asks you to determine the final pressure. This deals with the combined form of the ideal gas law, which states that the product of the initial pressure and volume, divided by the initial temperature, equals the product of the final pressure and volume, divided by the final temperature (P₁V₁/T₁ = P₂V₂/T₂).
Given that the initial pressure P₁ is 1 atm, initial volume V₁ is 24 L, initial temperature T₁ is 263 K, final volume V₂ is 35 L, and final temperature T₂ is 298 K, we can substitute these values into the equation to solve for the final pressure P₂.
Therefore, P₂ = P₁V₁T₂ / V₂T₁ = (1 atm × 24 L × 298 K) / (35 L × 263 K) ≈ 0.725 atm. So, the final pressure of the gas would be approximately 0.725 atm.

Answer
The force on the left across the lab table.
Explanation
The Newton's third law of motion states that; action and reaction are equal but a ct in opposite direction.
When the block of is pulled on the right with a force of X Newtons then there is a force -X Newtons applying and equal force on the left. For every action there must be a reaction with is equal and applying in the opposite direction.
So, if the block is pulled on the right by a force of 8 N there is another equal force applying on the left.
Answer:
1.Cp₁ = 1.2 J/g.⁰C
Explanation:
For new material:
m₁ = 25 g
T₁ = 80⁰C
specific heat of water = Cp₁
For water :
m₂ = 100 g
T₂ = 20⁰C
The final temperature T=24⁰C
We know that specific heat of water Cp₂ = 4.187 kJ/kg.K
The heat lost new material = Heat gain by Water
m₁ Cp₁ ( T₁ - T ) = m₂ Cp₂ (T- T₂)
25 x Cp₁ (80- 24 ) = 100 x 4.817 (24 - 20 )
Cp₁ x 56 = 4 x 4.187 x 4
Cp₁ = 1.19 kJ/kg.K
Cp₁ = 1.2 J/g.⁰C

-- Buoyancy is used to bring crude oil from Saudi Arabi to refineries in the US. The oil is loaded into tanks that are part of supertanker ships. Buoyancy is created by their ship-shape, so they float on water, and they can be dragged across the ocean on top of the water.
-- Buoyancy is used for a cheap thrill on the weekend. People drive out in the country and find a place where they can buy a ride under a hot-air balloon. The balloon is filled with hot air from a propane burner under its opening, and then it rises up off the ground because of its buoyancy in cool air.
-- Buoyancy is used cleverly by factories, to get rid of their gaseous and particulate wastes. The wastes are heated, and then blown into tall "smokestacks" connected to the factory. Then they rise because of the buoyancy created by hot stuff in cool air. When they leave the top of the smokestack, they keep rising for a while. Then, weather systems blow them away from the factory, over into other people's neighborhoods, where they finally sink to the ground in places where nobody knows where they came from.
-- Buoyancy is used in teapots, coffee makers, and lava lamps. A heat source is placed under the bottom of the container. Heat is conducted through the bottom of the container, and it heats the fluid that's in contact with the inside of the container on the bottom. The hot fluid rises to the top of the container, because of the buoyancy created by hot stuff surrounded by cool stuff. At the same time, cool stuff flows in to take its place at the bottom.
In pots and pans and tanks where buoyancy is used this way, the motion of the fluids up and down and around is called "convection".
