Answer:
GPE is directly proportional to mass as
U=mgh
hence more mass more gpe
ans is one with 500N
Answer:
c
Explanation:
While people are working, they need to have a strong bond with their teammates,to face all the hardships .
thus, teammates work together, win and lose together, and often eat and live together.
The kinetic molecular theory of matter offers a description of the microscopic properties of atoms (or molecules) and their interactions, leading to observable macroscopic properties (such as pressure, volume, temperature). An application of the theory is that it helps to explain why matter exists in different phases (solid, liquid, and gas) and how matter can change from one phase to the next.
Answer:
3565 J
Explanation:
F = Force applied = 1550 N
s = Displacement caused by the applied force = 2.3 m
= Angle at which the force is applied = 0°
When we multiply force, displacement and the angle at which the force is applied we get work
Work done is given by
The work done by team A is 3565 J
Answer:<span>Humid air is lighter, so it has lower pressure.
The reason is the molecules of water are H2O, whose molar mass is 18 g/mol.
These molecules displaces molecules of N2 and O2, whose molar masses are:
N2: 2*14g/mol = 28 g/mol, and
O2: 2*16g/mol = 32 g/mol.
Then molecules of 28g/mol and 32 g/mol are being replaced with molecules of 18g/mol, leading to a lower weight of the same volume of air, which results in lower pressure.
