Aplane whose air speed is 150 mi/h flew from abbot to blair in 2h with a tail wind. on teh return trip against the same wind, the plane was still 60 mi from abbot after two hours. find the wind speed and the distance between abbot and blair

Lets say that an object of a certain volume has a certin mass. what happens to its mass when you double its volume?

As a pendulum bob swings back and forth several times, the maximum height it reaches becomes less and less. this is because more and more of the pendulum bob's energy is being transformed into a. heat energy b. kinetic energy c. potential energy d. kinetic energy and potential energy

During the experiment if you could triple the breakaway magnetic force with all other quantities left unchanged, what is the new value for the critical velocity if it was v0 (initial velocity), initially? (b) now if you halved the radius with all other quantities left unchanged, what is the new critical velocity if it was v0 (initial velocity), initially? (c) if during the experiment, critical velocity quadrupled with all other quantities left unchanged, what is the new breakaway force if its magnitude was initially f0,?
