the reason is certainly related to the fact that the speech is put in frame of 20ms. And when the GSM was invented, 20ms could be encoded/compressed/etc. into 4x0.577 ms.20ms => 4x0.577ms = 2.3mseach 20ms, one user needs 2.3ms.So during 20ms on the air, only 8 calls can be multiplexed.20/2.3 = 8.7The remaining is used for in band signalling (sacch).
6,000 joules at 20m/s
To calculate the acceleration, you need to divide the net force by the mass.
500kgx9.81=Ax20=x
Can't be answered w/o knowing the mass.
-5 m/s² (APEX)
20ms east
The speed of the object is given as "20 m/s", period, and there is no information given concerning the direction of its motion, or any change in the direction.. Since the speed of the object and its direction are constant and not changing, the net forces on it ... the resultant of all gravitational, frictional, and horizontal forces ... is zero.
a few things missing: - How fast is the acceleration? - How long does it take to go from 4ms to 20ms?
To find out an average for anything, you need to take 20 and 50, multiply the two numbers, divide by how many numbers there is, which there is only 2, so it averages to 50ms. I am still in school so I know this is the correct answer
Initial kinetic energy = 1/2 M Vi2 Final kinetic energy = 1/2 M Vf2 Difference = 1/2 M (Vf2 - Vi2) = 2,500(302 - 202) = 2,500(900 - 400) = 2,500 x 500 = 1,250,000 joules
The response rate is how quickly the pixels are able to change colors. This is important if you have moving images, such as in websites or gaming. The response rate is measured in milliseconds. A response rate should be a lower number for a better performance. An 8ms response time works very well for gaming and a 20ms response time works fine for things like word processing.
