Answer:
The question is incomplete. Here is the complete question:
A Blu-ray disc is approximately 8 centimeters in diameter. The drive motor of the Blu-ray player is able to rotate up to 10,000 revolutions per minute, depending on what track is being read. (a) Find the maximum angular speed (in radians per second) of a Blu-ray disc as it rotates. (b) Find the maximum linear speed (in meters per second) of a point on the outermost track as the disc rotates.
Answer:
(a) 1047.2 rad/sec
(b) 41.9 m/s
Explanation: Please see the attachments below
We know, F = m*a
Here, F = 600-400 = 200 N downwards
m = 60 Kg
Substitute their values,
a = 200/60
a = 20/6
a = 10/3
a = 3.33 m/s² downwards
In short, Your Answer would be 3.33 m/s² downwards
Hope this helps!

Explanation:
1. Mass of the proton, 
Wavelength, 
We need to find the potential difference. The relationship between potential difference and wavelength is given by :
V = 45.83 volts
2. Mass of the electron, 
Wavelength,
We need to find the potential difference. The relationship between potential difference and wavelength is given by :
V = 84109.27 volt
Hence, this is the required solution.
The answer to this question would be: <span>A) animals that live in deserts
</span>Desert temperature is high, especially in the day, <span>An animal that lives in the desert needs to adapt to the high temperature either by reducing the heat or by increasing heat loss. By becoming nocturnal, the animal also able to evade the sunlight so it was less exposed to the heat.
Unlike other option, the desert is lacking water. Desert is mostly dry and water would be a resource that hard to find. In this case, k</span><span>idneys adapted to check water loss would be a great help</span>
