<span>Every falling object on Earth will experience air resistance,
unless it's falling inside a vacuum chamber.
The air resistance will increase as the speed of the falling object
increases.
At the point when the air resistance equals the weight, there is no
acceleration, and the object will fall with constant speed after that.</span>
<span>When the attraction of the strong force is weaker than the repulsion of the electrostatic force. </span>
The formula for speed is distance÷time. The distance in this situation is 27km and the amount of time taken to cover that distance is 5 hours. Now, we substitute the values into an equation:
Speed = 27km/5h
Speed = 5.4km/h
Therefore, Desmond's speed is 5.4km/h.
The wave travels at the speed of sound in water:
.
The frequency of the wave is
so we can find its wavelength
by using the basic relationship between frequency, wavelength and speed of the wave:
Answer: mammals may be relatively better at solving problems than birds.
