Answer:
C and D
Explanation:
But really, You should be able to answer this with the tech knowledge of a tomato. You're given four answers, and are to choose which two are explain the reliability of digital storage.
The first two describe bad nasty things, the second two describe beneficial things.
So logically....
We are given the equation:
<span>x = 11t^2
</span>
We use that equation to calculate for the distance traveled.
For (a)
At t=2.20 sec,
x =53.24 meters
At t=2.95 sec,
x =95.73 meters
Velocity = (95.73 meters - 53.24<span> meters) / (2.95 s - 2.20 s ) = 56.65 m/s
</span>For (b)
At t=2.20 sec,
x =53.24 meters
At t=2.40 sec,
x =63.36 meters
Velocity = (63.36 meters - 53.24<span> meters) / (2.40 s - 2.20 s ) = 50.6 m/s</span>
Frequency = velocity/wavelength
Frequency = 10/20
Frequency = 0.5 Hz
Hi there!
I believe the answer is transversal or transverse.
