<u>Frequency is the number of waves that passes at a given point every second.</u> The lower the frequency, the less waves there are. The higher the frequency, the more waves. <u>A wavelength is the distance between two frequency waves. </u>The higher the frequency, the less distance from two waves. The lower the frequency, the longer distance from two waves.

Wavelength=velocity/frequency

Explanation:

Wavelength is inversely proportional to frequency

Wavelength=velocity/frequency

A rifle has a mass of 7-kg and the bullet has a mass of 0.7-kg. If the velocity of the bullet is 350-m/s after the rifle is fire
nevsk [136]

Answer:

-35 m/s

Explanation:

Momentum is conserved.

Momentum before firing = momentum after firing

m₁u₁ + m₂u₂ = m₁v₁ + m₂v₂

Before the bullet is fired, the bullet and rifle have no velocity, so u₁ and u₂ are 0.

0 = m₁v₁ + m₂v₂

Given m₁ = 0.7 kg, v₁ = 350 m/s, and m₂ = 7 kg:

0 = (0.7 kg) (350 m/s) + (7 kg) v

v = -35 m/s

The rifle recoils at 35 m/s in the opposite direction.

You are in a tall building located near the equator. What happens to your tangential speed due to the earth's rotation as you ri
8_murik_8 [283]

Answer:increases

Explanation:

If we are going upward in an elevator from the ground floor to the top floor then it indicates that your distance from the center of the earth is increasing while the time period remains the same.

If the radial distance is increased then the tangential velocity of the object must be increased because the time period is the same.

This can be best explained by taking an example of a car moving in a circle of radius r. If radial is increased for the same period then the car has to travel at a higher velocity to make in time.

A trombone has a variable length. When a musician blows into the mouthpiece and causes air in the tube of the horn to vibrate, t
tiny-mole [99]

Answer:

B) The frequency will increase

Explanation:

The length of the instrument is given by

L=\dfrac{\lambda}{2}\\\Rightarrow \lambda=2L

Wavelength is given by

\lambda=\dfrac{v}{f}

\dfrac{v}{f}=2L\ or\ L\propto \dfrac{1}{f}

It can be seen that the length is inversely proportional to the frequency.

Here, the length of the trombone is decreasing so the frequency will increase.

What is the difference between mechanical advantage and distance advantage? ​
eimsori [14]
A machine's distance mechanical advantage shows the effectiveness of the machine in moving an object a greater distance than the input distance. The equation for the distance mechanical advantage is the output distance divided by the input distance. Note: Most science books only consider force mechanical advantage. I HOPE THIS HELPS!
