The displacement of the engine in a Ford Mustang is 5.0L. Convert this to cubic inches

A horizontal disk with a radius of 10 cm rotates about a vertical axis through its center. The disk starts from rest at t = 0 and has a constant angular acceleration of 2.1 rad/s2. At what value of t will the radial and tangential components of the linear acceleration of a point on the rim of the disk be equal in magnitude?

A. 0.55 s B. 0.63 s C. 0.69 s D. 0.59 s E. 0.47 s

A Doppler red shift indicates

a. a shift toward higher frequencies. b. a shift toward shorter wavelengths. c. that a light source is receding relative to the observer. d. none of these.

As viewed from any place within the continental United States, noon on apparent solar time is defined as the moment when the Sun is

The Bernoulli effect is responsible for the lift force on an airplane wing. Wings must therefore be designed so as to insure that

A) air molecules will be deflected downward when they hit the wing. B) air molecules will be deflected upward when they hit the wing. C) air molecules move more rapidly past the upper surface of the wing than past the lower surface. D) air molecules move more rapidly past the lower surface of the wing than past the upper surface. E) wings are thick enough to create a significant pressure difference between the top and bottom surfaces of the wings because of the different heights of these surfaces.
