What of a wave is a measure of the energy it carries

1 answer:

8 0

The amplitude of a wave is a measure of the energy it carries. The amplitude of a wave is the distance between the midline of a wave and its crest or trough.

Amplitude measures the amount of energy being transported by a wave. The larger the amplitude, the more the energy that a wave has.

Wave such as water waves have energy. Smaller waves have less energy because they have a smaller amplitude. Tsunamis have very high amplitudes and thus have a huge amount of energy

A cyclist is travelling eastwards at a velocity

VMariaS [17]

Answer:

0.02 m/s^2

Explanation:

change in velocity= 4.5m/s - 2.3m/s = 2.2 m/s

acceleration= change in velocity/change in time

acceleration= 2.2/120= 0.0183

= 0.02 (to 2 significant figures)

· A car moves at 12 m/s and coasts up a hill with a

Zigmanuir [339]

Explanation:

Given that,

Initial speed of a car, u = 12 m/s

Aceleration, a = -1.6 m/s²

(a) The displacement of car after 6 seconds is :

$d=ut+\dfrac{1}{2}at^2\\\\d=12\times 6+\dfrac{1}{2}\times (-1.6)\times 6^2\\\\d=43.2\ m$

(b) The displacement of the car after 9 seconds is :

$d=ut+\dfrac{1}{2}at^2\\\\d=12\times 9+\dfrac{1}{2}\times (-1.6)\times 9^2\\\\d=43.2\ m$

Hence, this is the required solution.
