Answer:
The value is
The force will be outward
Explanation:
From the question we are told that
The diameter of the disk is
The external pressure on Mars is
From the question we are told that
Internal pressure = External pressure
Generally the external Force on earth is
Here is the atmospheric pressure with value
So
=>
=>
Generally the external Force on Mars is
=>
=>
Net force is mathematically represented as
=>
=> converting to pounds
=>
Given that that the value is positive then the force will be outward
Answer:
work done on the object by gravitational force = 0 joules
Explanation:
work = force × displacement
force = mass × acceleration
so,
work = mass × acceleration × displacement
we know that mass= 10 kg , gravitational acceleration= 9.8
and displacement= 0 m since the object is not moving vertically.
so,
work = 10 × 9.8 × 0 = 0 joules
