What are the conditions for maximum work done in physics?
The conditions for maximum work done are when the force applied is in the same direction as the displacement, as well as when the force has the maximum magnitude possible. This results in the maximum transfer of energy from one form to another.
How can we use the work-energy theorem to determine the maximum height reached by an object?
The work-energy theorem states that the work done on an object is equal to the change in its kinetic energy. By calculating the work done on an object as it moves against gravity, we can determine the maximum height it reaches by setting the object's kinetic energy to zero at that point.
What should be the angle between force and displacement to get the minimum work and maximum work?
To minimize work, the angle between force and displacement should be 90 degrees (perpendicular). This is because work done is calculated as the dot product of force and displacement vectors, and the cosine of 90 degrees is 0, resulting in zero work. To maximize work, the angle should be 0 degrees (parallel), as the cosine of 0 degrees is 1, resulting in maximum work done.
Which thermodynamic process gives maximum work?
Reversible adiabatic expansion/compression
WHAT IS FORMULA TO CACULATE WORK DONE PER PERSON?
The formula to calculate work done per person is: Work done = Total work / Number of people. This formula divides the total work required to be done by the number of people doing the work to determine the work done per person.

What can be said about a situation in which work done is negative?
the formula F.S cos angle is used (the dot product) so if angle is 0,cos angle=1 hence work done is positive and maximum if angle is 90 so cos 90 is 0 hence work done is minimum if work done is negative the angle is 180 The work done by friction is always negative (opposite the force) Since work is force x displacement, a negative value for work could mean that the displacent was negative
What is the maximum amount of work that a gas can do during a constant-volume process?
The maximum amount of work that a gas can do during a constant-volume process is zero, because work done by a gas is given by the formula W = PΔV and volume change (ΔV) is zero in a constant-volume process.
Why are managers important to an organization?
He gets things done. He manages the work, staff, and administration and strives always for maximum efficiency and savings.
Who has done maximum donation of blood?
a person
What is the maximum wind speed OSHA allows for personnel to work outdoors?
Most outdoor work has no maximum wind speed. Crane lifting and the like will have maximum speed criteria, but this will depend on the specific crane and the work being done and will be set by the crane manufacturer..
Have you done your work What is the passive voice of this sentence?
Has your work been done?
What is work done if there is nodisplacement is 0?
Work Done = Force x Displacement, so if the displacement is zero, the work done will be zero. There will be no work done.
Which is A 2 kg ball is thrown upward with a velocity of 10 m s What is the work done by gravity when the ball reaches its maximum height?
force = mass * acceleration = 2 * -9.82 = -19.64 newtons work done = force * distance = -19.64 * 5.092 metres = -100 joules
Is it possible to have more than ten jobs at the same time?
It is not physically possible to work 10 jobs. Three is about the maximum that a person can work at one time. I have done it as well as go to school full time..
