Give 2 reasons where does the lost energy and elements in a water heater go.

That process is it when hot water flows from the bottom to the top inside a tank

What are the measurement errors associated with coaxial cylindrical rotational viscometer

A box of mass m is stacked on the top of a box of mass 3m. The surface of the table on which they sit is extremely smooth, but the surfaces of the boxes are not. If a force F is applied to the larger box, and the boxes do not move relative to each other, what is the static friction force on the less massive box?

An object slides on the flat ground. It comes to a stop under the influence of friction with a constant acceleration magnitude of 2.45 m/s2. What is the coefficient of kinetic friction between the object and the ground?

A wooden block slides directly down an inclined plane with a constant speed of 6.0 m/s. What is the coefficient of kinetic friction if the incline is angled at 25º.

Find the magnitude of the dot product of the two vectors B=6i+j+2k,D=-i+3j.what is the angle between B and D.

If the displacement of a body at an instant is given by:
X=22+At+B root t
Where(x)is measured in meters and (t)is measured in seconds.
Find dimensions of A and B

What is the angle at which both the height and the range of projectile is maximum?

A mass of 165 kg is hanging on an extension of the pole(L-shaped pole) and i want to calculate the forces of distribution on various points of the pole so that it will not collapse

1.) Explain the difference between average velocity and instantaneous velocity. Is it possible for these two values to be different?

2.) Given a position-time graph, describe how you would determine the average velocity and instantaneous velocity,
