Given that the physical quantities s, v,a, and t have dimensions[s]= L, [v]= LT-1,[a] = LT-2, and [t] = T. Determine whether each of the following equations is
dimensionally consistent:
(a) s = vt + 1/2at²
(b) s = vt² + 1/2 at
(c) v = sin(at² /s).

Acar travels along a highway with a velocity of 24 m/s, west. the car exits the highway; and 4.0 s later, its instantaneous velocity is 16 m/s, 45° north of west. what is the magnitude of the average acceleration of the car during the four-second interval?

Starting with only the balmer series light (visible light), how could we ensure that the solar panels generate a current that mark can use for his power station? a)by gradually increasing the brightness (amount) of light that we shine on it. b)by gradually increasing the frequency of the light we shine on it. c)by gradually increasing the wavelength of the light that we shine on it.
