Why do astronauts need to wear pressurized suits in space? a. because air pressure is so great in space they could be crushed without the suits. b. because without the pressure in the suits the astronauts could freeze to death. c. because space is a vacuum, the astronauts' bodies could explode without the suits. d. the pressure protects them from solar radiation.

What is a possible result of higher air temperature caused by global warming

The scalar triple product computes the magnitude m of the moment of a force vector f about a specified line. it is m = (r × f) · n, where r is the position vector from the line to the point of application of the force and n is a unit vector in the direction of the line. use matlab to compute the magnitude m for the case where f = [12, −5, 4] n, r = [−3, 5, 2] m, and n = [6, 5, −7].

Which of the following examples illustrates static friction? a box sits stationary on a ramp. a ball rolling on the lawn eventually comes to rest. a car rounds a curve on a road. a fish swims upstream.
