The angular velocity is defined as "the angle changing over time."
From the given of the problem:
m = 100g
rate of revolution = 50 rev / min
Therefore, using the formula:
angular velocity = rate of revolution x 2*pi / revolution
Substituting:
angular velocity = (50 revs / min) x ( 2*pi radians / rev ) = 100*pi radians / min
As you can see, mass is not a part of the equation for solving the angular velocity therefore the amount of mass does not affect its value.
Answer: 7.5 ml
Explanation: Density= mass/ volume.
So, volume = mass / density
= 15g / 2 g/ml
= 7.5 ml
Answer:
W = 343.2 J
Explanation:
Given that,
Mass of bale of hay = 26 kg
Horizontal force exerted = 88 N
Distance moved, d = 3.9 m
Work done, W = Fd
Put all the values,
W = 88 N × 3.9 m
= 343.2 J
So, the work done is 343.2 J.
The Vapor Pressure of water increases by 5.1%. when the temperature increases by 1 °c from 14°c to 15°c.
The vapor pressure of a liquid, sometimes referred to as the equilibrium pressure of a vapor above its liquid, is the pressure of the vapor produced by the evaporation of a fluid (or solid) over a sample of the liquid (or solid) in such a closed container (or solid).
Vapor pressure is the term for the force that is produced as liquids evaporate. Three factors commonly have an effect on a vapor press: surface area, intermolecular forces, and temperature. The vapor pressures of molecules change with temperature.
