Answer:
frequency = 0.5 Hz and speed = 2 m/s
Explanation:
Given that,
The period of a wave, T = 2 s
Wavelength, 
If f be the frequency. So,
f = 1/T

Speed of a wave is given by :

So, the frequency of the wave is 0.5 Hz and speed is 2 m/s.
No. What most people call 'terminal velocity' is the speed of the falling
object when the downward force of gravity is equal to the upward force
of air resistance. At that speed, the vertical forces on the object are
balanced, so it stops accelerating, and falls at a constant speed.
If there were no atmosphere, there would be no upward force due to
air resistance. The falling object would continue to accelerate all the
way down until it went 'splat'.
This is exactly the situation for meteoroids or asteroids falling onto the Moon.
Answer:
The correct answer is the sea
<span>a. A solid will gain kinetic energy and become a liquid.</span>
The correct answer is A) entrepreneurs organize the other factors, which are land, labor, and capital. The basic premise is that having land, labor, and capital, without someone pushing to develop a new product or service out of it, does not result in production per se.
