Answer:
The answer to your question is 5.5 x 10¹² kg/km³
Explanation:
Data
density = rho = X
mass = 5.94 x 10²⁴ kg
volume = 1.08 x 10¹² km³
Process
To solve this problem use the density formula and simplify it to find the result.
Formula
density = 
Substitution
density = 
Simplification and result
density = 5.5 x 10¹² kg/km³
Answer:
c) depends only on the type of fluid
Explanation:
The pressure of a fluid at a specific depth is given by:
where
is the density of the fluid
g is the gravitational acceleration
h is the depth
We see that for a given depth h, the pressure of the fluid depends only on its density, so only on the type of fluid. Therefore, the correct choice is
a) depends only on the type of fluid
The other choices are wrong because:
b) the pressure is exerted in every direction
c) the pressure does not depend on the total volume of the fluid, but only on the depth h
Answer:
Momentum is define as the product of the mass and velocity of a body. It is measured in Kgm/s.
Explanation:
Momentum is the product of mass and velocity of an object. When an object or a body of mass 'm' is moving with velocity 'v', then its momentum can be determined as;
momentum (P) = mass × velocity
i.e P = m × v
= mv
It is measured in Kgm/s.
The change in momentum of a body is referred to as its impulse (Ft).
ΔP = m(v - u) = Ft
Where: P is the momentum of the object, m is its mass, v is its final velocity, u is the initial velocity, F is the force and t is the time in which the force acts.
