Answer:
K = kg/m
Explanation:
as velocity has units of m/s V³ has units of m³/s³
power has units of J/s = N•m/s = kg•m/s²•m/s = kg•m²/s³
kg•m²/s³ = K(m³/s³)
K = kg•m²/s³•s³/m³
K = kg/m
Answer:
(A) Spring constant will be 126.58 N/m
(B) Amplitude will be equal to 0.177 m
Explanation:
We have given mass of the block m = 200 gram = 0.2 kg
Time period T = 0.250 sec
Total energy is given TE = 2 J
(A) For mass spring system time period is equal to 
So 
Now squaring both side
K = 126.58 N/m
So the spring constant of the spring will be 126.58 N/m
(B) Total energy is equal to 
, here K is spring constant and A is amplitude
So 
A = 0.177 m
So the amplitude of the wave will be equal to 0.177 m
Answer:
The relation between frequency and time period is given by:
f = 1/T
Explanation:
In a wave motion, the particle move about the mean position with the passage of time. The particles rise to reach the highest point which is crest, and similarly falls to reach the lowest point which is trough. The cycle keeps on repeating.
The time period of the wave can be defined as the time taken to complete one such cycle. Time period is given by:
T = 2π/ω
Frequency can be defined as the number of cycles completed in unit time, which can be taken as the inverse of time period. frequency is given by
f = ω/2π
or
f = 1/T
This has to do with independent and dependent variables. The independent variable is what affects the dependant variable, so the question is, does a students mark on a test affect their hours of sleep or does their hours of sleep affect their test results? Which one makes more sense? I would say the latter.
