7. A satellite's speed is 5,000 m/s. After 1 min it is 10,000 m/s. What is the satellite's acceleration?

Why is there friction between objects

Determine the maximum r-value of the polar equation r =3+3 cos 0

Africtionless piston-cylinder contains 50 l of saturated liquid r-134a. the piston has a mass and an area resulting in an applied pressure of 500 kpa on the refrigerant. the refrigerant is now heated until its temperature rises to 70∘c. calculate the work (in kj) done during this process.
