the velocity of sound in a certain medium is 1000 m/s. If sound wave has a frequency of 500 Hz, the wavelength would be _.

Two stars that are in the same constellation: 1. Two stars that are in the same constellation: must both be part of the same cluster of stars in space. 2. must both have been discovered at about the same time. 3.

A ball is thrown up into the air with an initial velocity of 64 ft/sec. The ball is 4 ft above the ground when it is released. Its height, in feet, at time t seconds is given by: h (t) = - 16t^2 + 64t + 4.

Consider a system of an 85.0 kg man, his 14.5-kg dog, and the earth. The gravitational potential energy of the system increases by 1.85 103 J when the man climbs a spiral staircase from the first to the second floor of an apartment building.

The resolution of the eye is ultimately limited by the pupil diameter. What is the smallest diameter spot the eye can produce on the retina if the pupil diameter is 3.93 mm? Assume light with a wavelength of λ = 550 nm.

Calculate the approximate force on a square meter (1.00 m3) of sail, given the horizontal velocity of the wind is 6.00 m/s parallel to its front surface and 3.50 m/s along its back surface. Take the density of air to be 1.29 kg/m3.
