Answer:
Explanation:
True
It is correct as the total rotational energy is the sum of transnational kinetic energy of each small piece of the object.
Consider a rigid body made of small particles each of mass dm have same angular velocity ω and the radius of the rotational path is r.
The velocity of each particle is v = r ω
So, the kinetic energy of each particle is
dK = 0.5 dm x v² = 0.5 x dm x r² x ω²
The total kinetic energy
K = 0.5 x I ω²
where, I is the moment of inertia
You are correct. Mountains are part of the lithosphere.
Answer: 0.176 m
Explanation:
Given
Pressure of glycerine, p = 2170 Pa
Density of glycerine, ρ = 1.26*10^3 kg/m³
Depth, h = ?
To solve, we use the formula of pressure
P = ρgh
Where
ρ = density of glycerine
P = pressure of glycerine
g = acceleration due to gravity
h = depth of glycerine
2170 = 1.26*10^3 * 9.8 * h
2170 = 12348 * h
h = 2170 / 12348
h = 0.176 m
Therefore, the depth below the surface at which the pressure of glycerine is greater than the atmospheric pressure is 0.176 m
Explanation:
The chemical formula of a compound is a representation which shows all the elements therein and the mole relationship between them expressed as subscripts.
Water H₂O Hydrogen peroxide H₂O₂
Contrast
Water is a compound made up of 2 moles of hydrogen and 1 mole of oxygen
Hydrogen peroxide is made up of two moles of hydrogen and and 2 moles of oxygen.
Comparison:
Water and Hydrogen peroxide are made up of two elements:
