Answer:
The maximum displacement ,A= 0.047 m
Explanation:
Given that
Mass, m = 45 g= 0.045 kg
spring constant ,K= 240 N/m
Initial velocity at equilibrium ,v= 3.5 m/s
Lets take the maximum displacement is A
As we know that when the mass reached at the extreme position then the velocity of the mass will become zero.
From energy conservation
Now by putting the values
A=0.047 m
The maximum displacement ,A= 0.047 m
The answer is C :), I think.
The best way to treat CO poisoning is to breathe in pure oxygen. This treatment increases oxygen levels in the blood and helps to remove CO from the blood. Your doctor will place an oxygen mask over your nose and mouth and ask you to inhale.
Is that what you mean? Treat the poisoning? It’s a gas, so you can dispose of the gas. Unless you mean dispose of the detector?
Answer:
v = 1.224 m/s
Explanation:
given,
distance between the two successive maxima = 1.70 m
number of crest = 8
time = 11 s
frequency is equal to number of cycle per secod
velocity of wave
v = f x λ
v = 0.72 x 1.70
v = 1.224 m/s
Hence, the wave speed is equal to v = 1.224 m/s
