Oxygen has a molar mass of 32.0g/mol.
Part A What is the root-mean-square speed of an oxygen molecule at a temperature of 298K?
Part B What is its average translational kinetic energy at that speed? (In Joules)
A rope applies a horizontal force of 193 N to pull a crate a distance of 1.89 m across the floor. What is the work done by the frictional force
If a car traveling at 66 km/h will skid 22 m when its brakes lock, how far would it skid if it is traveling at 120 km/h when its brakes lock.
Initially, a swift-moving hawk is moving due west (in the -x direction) with a speed of 60 m/s; 5.0 s later it is moving due north (in the +y direction) with a speed of 25 m/s.
An ancient club is found that contains 120.00 g of pure carbon and has an activity of 7 decays per second. Determine its age assuming that in living trees the ratio of 14C/12C atoms is about 1.10x10-12. Note that half life of carbon-14 is 5700 yea..
What average thermal power is produced as rock stops?
what horizontal force is required to move the crate. If the coefficient of kinetic friction between a 33 kg crate and the floor is 0.26, what horizontal force is required to move the crate at a steady speed across the floor? Which is 84 I just help..
