Six grams of water changes from liquid to
vapor at a pressure of one atmosphere. In the
process, the volume changes from 0.9 cm^3
to2387 cm^3. The latent heat of vaporization of
water is 2.26 × 10^6 J/kg
Find the increase in internal energy of the
water.
Answer in units of J

A 534 g mass is connected to a light spring of
force constant 6 N/m that is free to oscillate
on a horizontal, frictionless track. The mass
is displaced 2 cm from the equilibrium point
and released from rest.
What is the maximum speed of the mass?
What is the maximum acceleration of...
Assume you are on a planet similar to Earth
where the acceleration of gravity is approximately 10 m/s
and the positive directions for
displacement, velocity, and acceleration are
upward.
At time t = 0 s, an elevator is at a displacement of x = 0 m with a velocity of v = 0 m/s.
A student whose...
A 2.5 kg mass accelerates at 6.1 m/s
in adirection 37◦north of east. One of the two
forces acting on the mass has a magnitude of
6.05 N and is directed north.
Determine the magnitude of the second
force.
Answer in units of N
I know you have to break it up into multiple components, but otherwise...
