If an object is dropped from a tall building and hits the ground 3.0 s later, what is the velocity of the object when it hits the ground? (Remember that the velocity is downward)

Lory of two metals, nickel and chromium, which are not too similar to each 5. Material - A copper wire has less resistance compared to a nichrome wire, even if they are the same size.

In the absence of friction, gravity, and all other external forces, what kind of speed will an object display if it travels from the bottom to the top of an inclined plane?

What is the main function of the nuclus

How does the force of gravity change as the distance between 2 objects change?

The force that one massive object exerts to attract another object is called

How do mountins building and volcanos relate to plate motion at convergent boundaries

A 20kg box is dropped 13m. how much work is done

Suppose a person whose mass is m is being held up against the wall with a constant tangential velocity v greater than the minimum necessary. Find the magnitude of the frictional force between the person and the wall

A ball is being rolled by a normal push of 1000N. it is opposed by friction which has a force of 0.3kN and air resistance which has a force of 23N. Calculate the resultant force.

Consider a Young's two-slit experiment in which the wavelength of light is 37% smaller than the distance between the slits.
