Answer:
The force ratio of a machine is 5 and it velocity ratio is 5 means that the load moved is five times the effort applied and the distance moved by the effort is five times the distance moved by the load at the same time interval.
Explanation:
Answer:
For a gas held at constant temperature, we can apply Boyle's law, which states that the product between the gas pressure and its volume is constant:

where
P is the pressure
V is the volume
As we see from the equation, P and V are inversely proportional to each other: this means that when the volume is decreased, the pressure increases, and vice-versa. The reason for that is that when the volume is decreased, the gas is compressed, so the molecules of the gas come closer to each other, so they collide more frequently with the wall of the container, exerting therefore a greater pressure.
Answer:

Explanation:
The difference between parallel and anti parallel alignment of the z component of an electron's spin magnetic dipole moment is given by

where μ= dipole moment B= strength of magnetic field and θ= angle between direction of magnetic field and dipole
here θ_2 and θ_1 are 180 and 0° respectively.


here μ is bohr magnetron or magnetic moment of an electron = 9.27×10^{-24}
put this value we get
