This is a problem that can be solved using free-fall motion analysis. Since the displacement (2.9m) is given, we can use the following equation to solve for the impact speed:
V^2 = 2gh
V = sqrt (2*9.8*2.9)
V = 7.54 m/s
The answer is modulation. In modulation a radio wave (also called the "carrier signal") is changed by the signal we want to send to the receiver, for example a song, or, in a wireless network, some data from a computer.
Answer:
Definiton 1.the refusal to accept or comply with something; the attempt to prevent something by action or argument
Definition 2. the ability not to be affected by something, especially adversely
Definition 3. the impeding, slowing, or stopping effect exerted by one material thing on another
Definiton 4: the degree to which a substance or device opposes the passage of an electric current, causing energy dissipation. Ohm's law resistance (measured in ohms) is equal to the voltage divided by the current.

Answer:
15.68 m/s
Explanation:
Given that,
She catches the ball 3.2 s later at the same height from which it was thrown.
When it reaches the maximum height, its height is equal to 0.
It will move under the action of gravity.
2 here comes for the time of ascent and descent.
So,
So, the initial upward speed of the ball is 15.68 m/s.
