<h2>The frequency of tuning fork B is 475 Hz</h2>
Explanation:
The number of beats produced is equal to the frequency difference between the two tuning forks .
The frequency of A = 480 Hz
Thus the frequency of B can be = 485 or 475 Hz
When B is filed , its frequency increases and it start producing 2 beats with A .
Thus it frequency must be 475 Hz , by filing , it increases to 478 Hz .
By which it gives 480 - 478 = 2 beats per second .
This cannot happen with frequency 485 , because by filing this difference increases in place of decreasing .
Answer:
The final velocity of the second player is 6.1 m/s.
Explanation:
The final velocity of the second player can be calculated by conservation of linear momentum (p):
(1)
Where:
: is the mass of the first football player = 110 kg
: is the mass of the second football player = 90 kg
: is the initial velocity of the first football player = 5.0 m/s
: is the initial velocity of the second football player = 0 (he is at rest)
: is the final velocity of the first football player = 0 (he stops after the impact)
: is the final velocity of the second football player =?
By solving equation (1) for
we have:


Therefore, the final velocity of the second player is 6.1 m/s.
I hope it helps you!
Should be 4x5x4!! If you take 8•15, you get 120!! There are six sides on a rectangular prism!! Thus leaving a value of 20 per side!! And I noted to properly equal out with the maximum volume it should mean 4•5=20!! Thus being 4•4•5
Answer:
When a color (colored fabric) absorbs light, it turns the light into thermal energy (heat). The more light a color absorbs, the more thermal energy it produces. Black fabric absorbs all colors of light and is therefore warmer than white fabric which reflects all colors.
