Answer:

Structural adaptation

Explanation:

When any physical body part of an organism helps it in surviving, then this mechanism of survival is called a structural adaptation. For example short tail of penguins helps them in balancing on their heels and tails due to which they are able to reduce heat released from their feet. Thus, any physical parts of an organism that helps them in coping with the surrounding physical environment /predators are refereed to as a mode of structural adaptation.

Answer:

$330.635$ meter per second square

Explanation:

Given

Height ,h $= 2.50$ m

Radius, r $= 1.50$ m

Distance travelled, $d = 15.9$ m

Since, the stone is released and it falls towards the sky, its initial velocity is zero

As per equation

$h = ut + \frac{1}{2} gt^2\\$ , we will evaluate "t"

Substituting the given values in above equation, we get

$2.5 = 0 *t + 0.5 * 9.81 * t^2\\t^2 = \frac{2.5}{0.5*9.81}\\ t = \sqrt{0.5096} \\t = 0.714$

Velocity

$= \frac{d}{t} \\= \frac{15.9}{0.714}\\= 22.27$

centripetal acceleration

$= \frac{v^2}{r} \\= \frac{22.27^2}{1.5}\\ = 330.635\\$

Answer: amplitude

Explanation: This describes the maximum amount of the displacement of a particle from it rest position. Usually, it is measured in metres

Since we are considering AM which is amplitude modulation, a technique used in electronic communication, most commonly for broadcasting information through a radio carrier wave. In amplitude modulation, the amplitude (signal strength) of the carrier wave is diversified in proportion to that of the message signal being broadcasted.
