The centre of mass of the objects is (0,1)m .

What do you mean by Centre of mass?

The centre of mass is a position defined relative to an object or system of objects .

We have given

m1=2kg , y1= 3

m2= 3kg ,y2=2.5m

m3=2.5kg ,y3= 0m

m4=4kg , y4= -0.5m

Ycm=mixi/mi

→2×3+3×2.5+2.5×0+4×0.5/4.5

→1m

Centre of mass of these object is at (0,1)m .

A flat circular plate of copper has a radius of 0.262 m and a mass of 61.5 kg.
Evgesh-ka [11]

Answer:

0.031 m

Explanation:

Density of copper = ρ =  8960 kg/m³

r = Radius = 0.262 m

m = Mass of plate = 61.5 kg

v = Volume of plate = Volume of cylinder = πr²h

\rho=\frac{m}{v}\\\Rightarrow 8940=\frac{61.5}{\pi r^2h}\\\Rightarrow h=\frac{61.5}{\pi 0.262^2\times 8940}\\\Rightarrow h=0.031\ m

So, thickness of plate is 0.031 m

7. A rightward force is applied to a book in order to move it across a desk at
Snezhnost [94]

Answer:

See the explanation below

Explanation:

In the attached image we can see the free body diagram and forces acting on the book.

Force F, which acts to the right, the friction force which acts in the opposite direction to the movement, i.e. to the left.

The force exerted by the weight of the book that is equal to the product of the mass of the book by the gravity of the book. The normal force that is equal in magnitude to the weight of the book but in the opposite direction.
