We can determine the ____________ of a wave when given the frequency and the wavelength.

1 answer:

7 0

Since the equation for frequency is:
frequency = velocity/wavelength, then the correct answer is B. velocity.
In order to calculate the velocity, we just need to multiply frequency and wavelength.

How long would it take you to travel 163 meters at a speed of 33 meters per second?

Leviafan [203]

Speed=

$33m {s}^{ -1}$

Distance=

$163m$

speed= distance/time

So,

Time= distance/speed

Time= 163/33

a train has a velocity of 44 metre per second and an acceleration of 4 metre per second square. its velocity after 10 seconds is

myrzilka [38]

Acceleration=Final velocity-Initial velocity /time.

Acceleration=a=4m/s².

Initial velocity= u= 44m/s

Final velocity=v= let it be v, since we are to look for the final velocity.

Time=t=10seconds.

Mathematically:

a=v-u/t

Substituting the givens into the equation.

4=v-44/10

cross multiply.

4×10 = v-44

40=v-44

40+44=v

v=84m/s

Anyone know what solution this is?

Pavel [41]

Answer:a means of solving a problem or dealing with a difficult situation.

Explanation:Some examples of solutions are salt water, rubbing alcohol, and sugar dissolved in water. When you look closely, upon mixing salt with water, you can't see the salt particles anymore, making this a homogeneous mixture. Let's make use of our salt water example to talk about the two main parts of a solution.

Define average velocity and instantaneous velocity when are they same

Vlada [557]

Answer:

Look to the explanation

Explanation:

Average velocity: is the average rate of change of displacement with

respect to time

Average velocity is a measure for distance traveled in a given time

We can calculate the average velocity by the rule $v=\frac{s}{t}$

where s is the displacement and t is the time

Instantaneous velocity: is the velocity of an object in motion at a

specific point (x , t)

instantaneous velocity is the limit of velocity as the change in time

approaches zero

We can calculate the instantaneous velocity by the rule $v=\frac{ds}{dt}$

Average velocity is equal to the instantaneous velocity when

acceleration is zero
