The bolts on a cylinder head of an engine require a torque of 95 N*m. If a wrench is 28 cm (or 0.28 m) long, what force perpendicular to the wrench must the mechanic exert at its end?

Aphysical change is a change in the size, shape,, or stafe of matter true or false

Review multiple-concept example 7 in this chapter as an aid in solving this problem. in a fast-pitch softball game the pitcher is impressive to watch, as she delivers a pitch by rapidly whirling her arm around so that the ball in her hand moves in a circle. in one instance, the radius of the circle is 0.626 m. at one point on this circle, the ball has an angular acceleration of 66.1 rad/s2 and an angular speed of 12.6 rad/s. (a) find the magnitude of the total acceleration (centripetal plus tangential) of the ball. (b) determine the angle of the total acceleration relative to the radial direction.

If the pressure in a gas is doubled while its volume is held constant. true or false
