An empty paint tin of diameterv0.150m and height0.120m has amass of 0.22 kg it is filled with paint to within 7mm of the top its total mass is then 6.50kg calculate for the paint in the tin the mass the volume and the density

Explanation:

1. Mass of paint

2. Volume of paint

The paint is contained in a cylinder.

V = πr²h

(a) Radius of can

r = d/2 = (0.150 m)/2  = 0.0750 m

(b) Height of paint

h = 0.120 m - 0.007 m = 0.113 m

(c) Volume of paint

3. Density of paint

answer; /// the above statement is (true);

when two balls of the different masses are dropped from equal height, they reach the ground at the same time .this is because they experience the same acceleration.

the acceleration is independent of mass.

thus when they are dropped they will always maintain the same velocity and travel the same distance (neglect air resistance of course) at the same time.
