A sound wave has a speed of 340 m/s and a frequency of 1000 hz. The period of the sound is closest to?

harina [27]

<h2>Relationship Between Frequency and Period</h2>

The frequency and the period are inversely proportional.

$f=\dfrac{1}{T}$ where T is the period

<h2>Solving the Question</h2>

We're given:

<em>v</em> = 340 m/s
<em>f</em> = 1000 Hz

Because the frequency and the period are reciprocals of each other, we can find the period of the sound by finding the reciprocal of the frequency:

$T=\dfrac{1}{1000}$

<h2>Answer</h2>

$T=\dfrac{1}{1000}$

A force of 6.0 N is applied horizontally to a 3.0 kg crate initially at rest on a horizontal frictionless surface. After the cra

Savatey [412]

Answer:

a. Yes, because the acceleration of the crate is 2.0 m/s².

Explanation:

Given

$Force = 6N$ --- f

$Mass = 3kg$ --- m

$Time = 1.5s$ --- t

$Velocity = 3.0m/s$ --- v

Required

Does the system support $F=ma$

Yes, it does and this is shown below

The crate is initially at rest; so:

$u = 0$

Using the first equation of motion

$v = u + at$

Substitute values for v, u and t

$3 = 0 + a*1.5$

$3 = 1.5a$

Make a the subject

$a = 3/1.5$

$a = 2$

Using $F = ma$

Substitute values for F and m

$6 = 3 * a$

Divide both sides by 3

$6/3 = 3/3 * a$

$2 = a$

$a = 2$

In both cases:

$a = 2$

<em>Hence, option (a) is correct.</em>

Why is physics used to study the heat absorbed by the ocean?

Wewaii [24]

Answer:

Explanation:

It absorbs gases, but also heat energy from the atmosphere, distributes them in its depths and thus slows down changes in the entire Earth system. The amount of energy absorbed by the ocean is therefore also an indication of the total heat absorbed by the planet.

What is force. what is a net force

algol13

Answer:

The net force is the vector sum of all the forces that act upon an object. That is to say, the net force is the sum of all the forces, taking into account the fact that a force is a vector and two forces of equal magnitude and opposite direction will cancel each other out.
