Impulse is just the product of mass and speed!
I = 1700 * 22.5 = 38,250 kg m/s
It does not have any special name for its units :(
It goes from positive to negative
Answer:
![F_{net} = 6.879\times 10^{- 7}\ N](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%206.879%5Ctimes%2010%5E%7B-%207%7D%5C%20N)
Solution:
As per the question:
Mass of first object, m = 120 kg
Mass of second object, m' = 420 kg
Mass of the third object, M = 69.0 kg
Distance between the m and m', d = 0.380 m
Now,
To calculate the gravitational force on the object of mass, M placed mid-way due to mass, m:
To calculate the gravitational force on the object of mass, M placed mid-way due to mass, m':
To calculate the gravitational force on the object of mass, M placed mid-way due to mass, m and m':
![F_{net} = F + F'](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%20F%20%2B%20F%27)
![F_{net} = 1.529\times 10^{- 7} + 5.35\times 10^{- 7} = 6.879\times 10^{- 7}\ N](https://tex.z-dn.net/?f=F_%7Bnet%7D%20%3D%201.529%5Ctimes%2010%5E%7B-%207%7D%20%2B%205.35%5Ctimes%2010%5E%7B-%207%7D%20%3D%206.879%5Ctimes%2010%5E%7B-%207%7D%5C%20N)
Answer:
The interference of two sound waves of similar amplitude but slightly different frequencies produces a loud-soft-loud oscillation we call <u>beats</u>.
Explanation:
When two objects vibrate at different frequencies, a fluctuating sound is heard, (loud-soft-loud). This phenomenon is known as beating. Loud sound is caused by constructive interference, and soft sound is caused by destructive interference.
