1 mile = 1.609 km
(135,000 km) x (1 mile / 1.609 km) = 83,885.1 miles
The work done on the box by the applied force is zero.
The work done by the force of gravity is 75.95 J
The work done on the box by the normal force is 75.95 J.
<h3>The given parameters:</h3>
- Mass of the box, m = 3.1 kg
- Distance moved by the box, d = 2.5 m
- Coefficient of friction, = 0.35
- Inclination of the force, θ = 30⁰
<h3>What is work - done?</h3>
- Work is said to be done when the applied force moves an object to a certain distance
The work done on the box by the applied force is calculated as;
where;
a is the acceleration of the box
The acceleration of the box is zero since the box moved at a constant speed.
The work done by the force of gravity is calculated as follows;
The work done on the box by the normal force is calculated as follows;

Answer:
Total work done in expansion will be
Explanation:
We have given pressure P = 2.10 atm
We know that 1 atm
So 2.10 atm
Volume is increases from 3370 liter to 5.40 liter
So initial volume
And final volume
So change in volume
For isobaric process work done is equal to
So total work done in expansion will be
Answer:10
Explanation:
You have to do speed divided by time so your answers 10
Answer:
As point B is located inside the copper block so net electric field at point B is j.
Explanation:
Consider the figure attached below. The net electric field at location B,that is inside the copper block is zero because when a conductor is charged or placed in an electric field of external charges, net charge lies on the surface of conductor and there is no electric field inside the conductor. As point B is located inside the copper block so net electric field at point B is zero as well direction of net electric field at point B is zero.
