Answer:
A) 854.46 kPa
Explanation:
P₁ = initial pressure of the gas = 400 kPa
P₂ = final pressure of the gas = ?
T₁ = initial temperature of the gas = 110 K
T₂ = final temperature of the gas = 235 K
Using the equation
![\frac{P_{1}}{T_{1}}=\frac{P_{2}}{T_{2}}](https://tex.z-dn.net/?f=%5Cfrac%7BP_%7B1%7D%7D%7BT_%7B1%7D%7D%3D%5Cfrac%7BP_%7B2%7D%7D%7BT_%7B2%7D%7D)
Inserting the values
![\frac{400}{110}=\frac{P_{2}}{235}](https://tex.z-dn.net/?f=%5Cfrac%7B400%7D%7B110%7D%3D%5Cfrac%7BP_%7B2%7D%7D%7B235%7D)
P₂ = 854.46 kPa
Work+Force*Distance. Rearranging, F=W/d. Calculating, the force must be 0.0215 N.
Answer:
Depending on where people are located in the world (Northern hemisphere, Southern hemisphere, etc) depends on the difference in direction (North, South, east, West) which is most likely why it'd look different.
Explanation:
I dunno if this is along the lines of an answer you're looking for, but hope this helps :)
Answer:
The strength of an electric field as created by source charge Q is inversely related to square of the distance from the source. This is known as an inverse square law. Electric field strength is location dependent, and its magnitude decreases as the distance from a location to the source increases.
Explanation:
Answer: c) the sun is the most massive object; gravitational attraction is related to mass.
Explanation:
Gravitational pull exists between any two objects having mass.
where symbols have their usual meaning.
All the planets including Earth revolve around the Sun because its the most massive object in the neighborhood and thus has high gravitational pull. This gravitational pull of Sun keeps the Earth in its orbit around it.
Hence, the correct answer is earth orbit the sun rather than any other body in the solar system because c) the sun is the most massive object; gravitational attraction is related to mass.
