Answer: The fundamental frequency of the slinky = 8Hz
An input frequency of 28 Hz will not create a standing wave
Explanation:
Let Fo = fundamental frequency
At third harmonic,
F = 3Fo
If F = 24Hz
24 = 3Fo
Fo = 24/3 = 8Hz
If an input frequency = 28 Hz at 3rd harmonic
Let find the fundamental frequency
28 = 3Fo
Fo = 28/3
Fo = 9.33333Hz
Since Fo isn't a whole number, it can't create a standing wave

The heat capacity is given by the expression:






When the
is measured in the calorimeter, we obtain a value, and since we know the mass of the material and we control the change in
, we can then determine the specific heat "C" by simply remplazing in the expression.
Answer:
option B) is correct
Explanation:
perception distance is the distance traveled by the vehicle when the driver perceive the hazard situation.
reaction distance is the distance traveled by the vehicle after seeing the hazard situation and reacting to it.
Braking Distance is the distance traveled by the vehicle after applying the brake.
so, the sum of Perception Distance + Reaction Distance + Braking Distance is called the total stopping distance
hence option B) is correct .
First we need to know the equation which is P=mv
Use the formula- 3.2 kg x m/s = 762 x V
divide 762 in both side to get the v by itself
now we will have 0.004193971166 and lets round it!
then we will have the answer of .0042
