Since the plane appears to be going in one direction (toward San Diego) in a straight line, you can assume that the change in position equals distance. Plug your known variables into the distance formula: \({\bigtriangleup x} =(150mph)(3.5h) = 525 miles\) TL;DR (Too Long; Didn't...
It is reasonable to assume that the echo time equals the time necessary for the radio wave to travel from the Earth to the Moon and back (that is, neglecting any time delays in the electronic equipment). Calculate the distance from Earth to the Moon given that the echo time was 2.56 s...
2. Since velocity times supply of money equals the gross domestic product, the money supply can be expected to grow comparatively rapidly to support GDP growth. 3. They panted with suspense as velocity sucked Di several meters underwater and the ferocious maelstrom whipped his figure to and fro...
FIG. 2.8. Variation of the sound pressure p (x,t) as a function of the distance along the tube for three frequencies, i.e., for three wavelengths. At x = l, the rms particle velocity is u0, and at x = 0, it is zero. The period T equals 1/f. Refer once more to Fig. 2.7...
Distance equals rate times time, but our problem is that the rate keeps changing. We must therefore approximate our answer. One way to approach the problem is to subdivide the time span into n intervals, to pick a time ti between each xi−1 and xi, and use g(ti) as the approximate...
In the position-time graph below identify the time or times at which the instantaneous velocity is zero. The figure shows the acceleration versus time graph of a particle moving along the x-axis. Its initial velocity is v_{0_{x = 8.00 m/...
For simplicity's sake, let's assume that old Gary ran to the west in a perfectly straight, 12-meter (32.8-foot) line, so his displacement equals the distance he traveled. We also know that it took him three seconds to cover the gap between his starting and ending points. Therefore, ...
1 yields the number of times the point oscillates each second, which is the frequency of the wave. Multiplying the wave's frequency by its wavelength, which is its physical length, yields the velocity of the wave. The relationship can be expressed as velocity equals frequency times wavelength....
it has no volume. Okay. Radius is 0. You could also write if you want volume equals 0. You can actually write out volume, so you don't think it's velocity. It's a point. It could be a small object that we simplified down to a point. So that's a point mass. The other one...
The swirl component of the predicted mean velocity, < uθ > is also in good agreement with the measurements to the same downstream distance. The predicted mean radial velocity, < ur >, however, is in poor agreement with the measurements close to the centreline in the near burner region, ...
