Answer:
Explanation:
density of the solid box material = 
density of the liquid material = 
Given that
solid box floats with two thirds of its volume submerged in a liquid
let V be the volume of the box
then,
⇒
so, the ratio of densities of solid and and the liquid is 2/3
Answer:
a= g sinθ
Explanation:
Given that
Angle ,θ = 15° (from the horizontal)
Lets take the mass of the block = m
The acceleration due to gravity = g
The acceleration of the block = a
When block slide down :
The gravitational force on the block = m g sinθ
By using Newton's second law
F= m a
F=Net force ,a acceleration ,m=mass
m g sinθ = ma
a= g sinθ
Therefore the acceleration of the block will be g sinθ.
