I have two (2) brilliant ideas:
1). Inside the metal that the body of the car is made of, and also between the two sheets of glass that the windows are made of, install a thin layer of material that absorbs RF (radio-wave) energy . . . like the material in the glass window of your microwave oven. Then, no radio waves from the cellular base station can get INTO the car, and no radio waves from your phone can get OUT of the car. The phone can't make a connection to the cellular network, you can't make or receive calls, and you can't connect to Instagram or Brainly, so you might as well just turn it off and save your battery until next time you're outside your car.
2). Somewhere inside the car, like under the dash or in the glove box, install a teeny tiny radio receiver that can recognize the signals coming OUT of your phone. Connect it to the car's electrical system so that when it hears signals from phones inside the car, it it shuts down the car's motor so you can't start or drive. The car only works when phones inside the car are either turned off or in Airplane Mode.
My ideas are so brilliant that I really should patent them, or copyright them, or whatever you do so that other people have to pay you to use your idea. But if you want to use them, that's OK. Just go ahead. I won't mind.
Answer:
The combined gas equation relates three variables pressure, temperature and volume when the number of moles is constant.
The equation is PV / T = constant. Which is valid for a fixed number of moles of the gas.
You can derive the combined gas equation from the combination of Bolye's law, Charles' law and Gay-Lussac's law, which needs some algebra.
Explanation:
Angular acceleration = (change in angular speed) / (time for the change)
Change in angular speed = (speed at the end) - (speed at the beginning)
For this fan, speed at the end = 7700 rpm, speed at the end = 0 .
Change in angular speed = -7700 rpm
Angular acceleration = (-7700 rpm) / (2.5 sec)
<em>Angular acceleration = -3,080 rev per minute / sec</em>
That's a perfectly good and true answer to the question, but the units are ugly. We really need to fix the units, and convert them into something prettier before we hand in this assignment.
1 rev = 2π radians, and
1 minute = 60 seconds .
So
Angular acceleration =
(-3,080 rev/min-sec) · (2π rad/rev) · (1 min/60 sec)
AngAccel = (-3,080 · 2π · 1 / 60) · (rev·rad·min / min·sec·rev·sec)
AngAccel = ( -102 and 2/3 · π) · (rad/s²)
<em>AngAccel = -322.5 radian/s²</em>
The answer is slightly left and slightly right of the curved end of the horseshoe.
