What properties of the wave define why it is found within this area of the spectrum?

MatroZZZ [7]

Answer:

Explanation:

Speed and medium are properties of a wave which is in common within an area of the spectrum of visible light. i.e;

Their medium of propagation

They both travel at the same speed ( speed of light )

The properties mentioned above are properties that define that wave is found within an area spectrum for visible light.

A 4.0kg bowling ball sliding to the right at 8.0 m/s has an elastic head-on collision with another 4.0 kg bowling ball initially

Kisachek [45]

We use the formula :

m1v1i + m2v2i = m1v1f + m2v2f

Substituting the values in:

4.0kg*8.0m/s + 4.0kg*0m/s = 4.0kg*0m/s +4.0kg*v2f

Calculating this we get:

32.0kg*m/s + 0kg*m/s = 0kg*m/s + 4.0kg*v2f

Rearrange for v2f:

v2f = $\frac{32.0kg*m/s}{4.0kg}$

This gives us 8.0 m/s as the final velocity of the second ball.

Since the collision is assumed to be elastic it means that the kinetic energy must be equal before and after the collision.

This means we use the formula:

Ek = $\frac{1}{2} *m*v^{2}$ + $\frac{1}{2} *m*v^{2}$ = $\frac{1}{2} *m*v^{2}$ + $\frac{1}{2}*m*v^{2}$

Substituting in values:

Ek = 0.5*4.0kg*(8.0m/s)^2 + 0.5*4.0kg*(0m/s)^2 = 0.5*4.0kg*(0m/s)^2 + 0.5*4.0kg*(8.0m/s)^2

This simplifies to:

Ek= 128J + 0J = 0J + 128J

This shows us that the kinetic energy is equal on each side therefore the collision is Elastic and no energy has been lost.

A bicycle has tires of radius 0.35 meters. If the bicycle is traveling at a constant speed of 7.8 m/s, at approximately what ang

lord [1]

22.3 rad/s

<h3>Further explanation</h3>

We will solve the question of uniform circular motion.

<u>Given:</u>

A bicycle has tires of radius $\boxed{ \ R = 0.35 \ meters \ }$
The bicycle is traveling at a constant speed of $\boxed{ \ v = 7.8 \ m/s \ }$

<u>Question:</u>

What angular speed are the tires rotating?

<u>The Process:</u>

Speed, angular speed, and radius are connected in the following formula:

$\boxed{\boxed{ \ v = \omega R \ }}$

The angular speed is worked out by

$\boxed{ \ \omega = \frac{v}{R} \ }$

All units are in the SI system so let us calculate the angular speed.

$\boxed{ \ \omega = \frac{7.8 \ m/s}{0.35 \ m} \ }$

Thus the value of the angular velocity of the rotating tire is $\boxed{\boxed{ \ \omega = 22.3 \ rad/s \ }}$

<u>An additional question:</u>

What is the frequency of tire rotation?

Recall this formula: $\boxed{ \ \omega = 2 \pi f \ } \rightarrow \boxed{ \ f = \frac{\omega}{2 \pi} \ }$

$\boxed{ \ f = \frac{22.3 \ rad/s}{2 \pi} \ }$

We get $\boxed{\boxed{ \ f = 3.55 \ Hz \ }}$
