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...
The period T equals 1/f. Refer once more to Fig. 2.7 which is drawn for t = 0. The instantaneous particle velocity is at its maximum (as a function of time). By comparison, in Fig. 2.8 at t = 0, the instantaneous sound pressure is zero. At a later time t = T/4 = 1/(4f...
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...
Outside of lattice simulations, studies invariably consider the terminal bubble wall velocity; that is, bubbles have reached a steady state where the driving pressure equals the friction from the plasma. The wall velocity of an individual bubble is a time-dependent quantity, with bubble walls ...
Velocity is the change in position (x), or distance, over time. If you know the change in position and the amount of time taken to complete the journey, you can determine velocity. If you have two of these variables, you can always solve for the third. T
The area of a rectangle is length times height. On the v vs. t graph, length is equal to time and height is equal to velocity. Therefore, area on this graph equals velocity multiplied by time, which is the distance traveled. This is an important result! Area on a v vs. t graph ...

mass and acceleration in the equation force (F) equals mass (m) times acceleration (a), written as F = ma. Another formula, acceleration (a) equals change in velocity (Δv) divided by change in time (Δt), calculates the rate of change in velocity over time. This formula may be wri...
Average velocity=change in distancechange in time=δsδt=s(t2)−s(t1)t2−t1 where t2 and t1 are the times between which we are finding the average. δs (‘delta s’) is used to represent a change in s and δt (‘delta t’) is used to represent a change in t....
The horizontal line is the velocity–time relation for an object moving at a constant velocity of 8 m/s. In 12 s the object moves 96 m, which is also represented by the shaded area in appropriate units. For motion with constant velocity the average velocity equals the instantaneous velocity...
