C. community
Explanation:
Community consists of a local residence, like a town.
Answer:
P = 5sin(880πt)
Explanation:
We write the pressure in the form P = Asin2πft where A = amplitude of pressure, f = frequency of vibration and t = time.
Now, striking the middle-A tuning fork with a force that produces a maximum pressure of 5 pascals implies A = 5 Pa.
Also, the frequency of vibration is 440 hertz. So, f = 440Hz
Thus, P = Asin2πft
P = 5sin2π(440)t
P = 5sin(880πt)
Answer:
The momentum before is equal to the momentum after
Explanation:
It is equal and should level out in an equation.
Jet streams are tied to global warming so I’m guessing hotter
Force= mass x acceleration
79=mass(3)
m=79/3
m=26.3 kg
