Answer:
for the body to float, the density of the body must be less than or equal to the density of the liquid.
Explanation:
For a block to float in a liquid, the thrust of the liquid must be greater than or equal to the weight of the block.
Weight is
W = mg
let's use the concept of density
ρ_body = m / V
m = ρ_body V
W = ρ_body V g
The thrust of the body is given by Archimedes' law
B = ρ_liquid g V_liquid
as the body floats the submerged volume of the liquid is less than or equal to the volume of the block
ρ_body V g = ρ_liquid g V_liquid
ρ_body = ρ liquid Vliquido / V_body
As we can see, for the body to float, the density of the body must be less than or equal to the density of the liquid.
Answer:
9.22 m/s
Explanation:
Vertical height, y = 36 m
Horizontal distance, d = 25 m
Let the initial velocity of projection is u and it is projected horizontally.
Let t be the time taken by the ball to hit the ground.
For horizontal motion
horizontal distance = horizontal velocity x time
d = u x t
25 = u x t .... (1)
Use second equation of motion for vertical direction
y = 0.5 x g t², as the initial vertical velocity is zero.
36 = 0.5 x 9.8 x t²
t = 2.7 second
Put in equation (1)
25 = u x 2.7
u = 9.22 m/s
Thus, the initial velocity with which the ball is projected horizontally is 9.22 m/s.
