Aplane comes out of a power dive, turning upward in a curve whose center of curvature is 1300 m above the plane. the plane's speed is 260 m/s.

a. calculate the upward force of the seat cushion on the 100 kg pilot of the plane.

b. calculate the upward force on a 90.0 g sample of blood in the pilot's head.

Aboat radioed a distress call to a coast guard station. at the time of the call, a vector a from the station to the boat had a magnitude of 45.0 km and was directed 15.0° east of north. a vector from the station to the point where the boat was later found is = 30.0 km, 15.0° north of east. what are the components of the vector from the point where the distress call was made to point where the boat was found? in other words, what are the components of vector c = b - a?

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,?

What happens to the vapor pressure of a substance when its surface area is increased at constant temperature?
