Amplitude is affected by the energy wave in the instrument. High energy wave means high amplitude and low energy wave means low amplitude.

<u>Explanation:</u>

The amplitude of a periodic variable is a measure of its change over a single period. There are various definitions of amplitude, which are all functions of the magnitude of the differences between the variable's extreme values.

The amount of energy carried by a wave is related to the amplitude of the wave. Amplitude of an instrument is directly affected by the wave of the energy in the instruments. High energy wave means high amplitude and low energy wave means low amplitude in the instrument.

A man is standing on the shore of a beach, up to his knees in water. Every second two waves hit him. What is the frequency of th

laila [671]

Answer:

f = 2 Hz

Explanation:

The frequency of a wave is defined as the no. of waves passing per unit of time. Therefore, the frequency of a wave can be calculated by the following formula:

$f = \frac{n}{t}$

where,

f = frequency of the wave = ?

t = time passed = 1 s

n = no. of waves passing in time t = 2

Therefore,

$f = \frac{2}{1\ s}$

An object has rotational inertia I. The object,initially at rest, begins to rotate with a constant angularacceleration of magnit

Tresset [83]

Answer:

L = I α t

Explanation:

given,

rotational inertia = I

initial velocity = ω₀

magnitude of acceleration = α

angular momentum = L

time = t

angular acceleration

$\alpha = \dfrac{\omega-\omega_0}{t}$

$\alpha = \dfrac{\omega - 0}{t}$

$\alpha = \dfrac{\omega}{t}$

ω = α t..............(1)

angular momentum

L = I ω

putting value from equation (1)

L = I α t

A transform boundary occurs where two tectonic plates _____.?

gladu [14]

Where they slide over each other.

Transform boundaries are formed or occur when two plates slide past each other in a sideways motion. They do not tear or crunch into each other (but the rock in between them may be ground up) and therefore none of the spectacular features are seen such as occur in divergent and convergent boundaries.

In a transform boundary, neither plate is added to at the boundary nor destroyed. They are marked in some places by features like stream beds that have been split in half and the two halves moved in opposite directions.
