Answer:
Sound intensity is measured with a sound level meter or Sound pressure Level (SPL) Meter.
Explanation:-
It measure sound intensity is the sound pressure level. The unit of measurement is decibels.
<span>The question is asking us to fill in the gap in: (gap) is a force of attraction that occurs between objects due to their mass.The correct answer is b. gravity. People don't know that gravity works both ways: both objects atract each. The reason why we're more attracted to Earth than Earth is pulled to us is that Earth has a much higher mass - the bigger the mass, the stronger the atraction</span>
Answer:
2 m/s and -2 m/s
Explanation:
The object travels with an angle of
60.0°
with the positive direction of the y-axis: this means that it lies either in the 1st quadrant (positive x) or in the 2nd quadrant (negative x).
If it lies in the 1st quadrant, the value of vx (component of v along x direction) is:
![v_x = v cos \theta = (4.0 m/s) cos 60.0^{\circ}=2 m/s](https://tex.z-dn.net/?f=v_x%20%3D%20v%20cos%20%5Ctheta%20%3D%20%284.0%20m%2Fs%29%20cos%2060.0%5E%7B%5Ccirc%7D%3D2%20m%2Fs)
If it lies in the 2nd quadrant, the value of vx (component of v along x direction) is:
![v_x = -v cos \theta = -(4.0 m/s) cos 60.0^{\circ}=-2 m/s](https://tex.z-dn.net/?f=v_x%20%3D%20-v%20cos%20%5Ctheta%20%3D%20-%284.0%20m%2Fs%29%20cos%2060.0%5E%7B%5Ccirc%7D%3D-2%20m%2Fs)
Answer:
It is made up of molecules which are pulled down to Earth by gravity. That pull makes molecules bump into each other, exerting pressure. Our bodies are specially adapted to living under 1 kilogram per square centimeter (14.7 pounds per square inch) of pressure pushing down on us at sea level!
