Answer : The volume of a sample of 4.00 mol of copper is 
Explanation :
First we have to calculate the mass of copper.
Now we have to calculate the volume of copper.
Formula used :
Now put all the given values in this formula, we get:
Conversion used :
Therefore, the volume of a sample of 4.00 mol of copper is
Explanation:
there is no relationship between small mass and the bigger mass, but it can be related with the acceleration. Since Force is constant, acceleration is inversely proportional to the mass. Greater the mass, lesser is the acceleration and vise versa
<span>B). it will decrease.
But, you should keep the temperature constant, 'cause according to Boyle's law, pressure of the ideal gases is indirectly proportional to it's volume but at constant temperature. So, don't confuse in that.
Hope this helps!

Answer:
I = M*(0.5R^2 + h^2)
w = sqrt [2*g*h / (0.5R^2 + h^2)]
Explanation:
Given:
- The radius of the cylinder R
- The mass of the cylinder M
- The distance between horizontal axis h
- The moment of inertia of cylinder I_c
Solution:
- When the axis of rotation and axis with respect to rotation inertia is required do not coincide then we have to apply parallel axis theorem to calculate the moment of inertia about the required axis which is at a distance h from body rotational axis as follows:
I = I_c + M*h^2
- Where I_c of a cylinder is = 0.5*M*R^2
I = 0.5*M*R^2 + M*h^2
I = M*(0.5R^2 + h^2)
- From conservation of total mechanical energy of the cylinder, the change in gravitational potential energy ΔP.E plus the change in kinetic energy ΔK.E of the cylinder must be zero:
ΔP.E = ΔK.E
M*g*h = 0.5*I*w^2
M*g*h = 0.5*M*(0.5R^2 + h^2)*w^2
w^2 = 2*g*h / (0.5R^2 + h^2)
w = sqrt [2*g*h / (0.5R^2 + h^2)]
Where,
w: The angular speed of the cylinder
