So as two objects are separated from each other, the force of gravitational attraction between them also decrease. if the separation distance between 2 objects is doubled (increased by a factor of 2), then the force of gravitational attraction is decreased by a factor of 4 (2 raised to the second power).
Hope this helps :)
Answer:
Fn = 246.2 N
Explanation:
I assume you meant meters per second squared for acceleration of the elevator. All you have to after your picture/free-body diagram is made is add the forces together. You could do this by finding them separately like I did or use Fn = m(Fg + Fe). I just calculated magnitude and didn't worry about signs.
Explanation:
The answer is D. Drivers must always yield to pedestrians and bicylists coming off a main road and always yield to emergency vehicles with lights on. Vehicles in a funeral must have lights on to alert other drivers of their pace and procession.
Yeah what the guy above me said
A pipe's length is equal to 1⁄2 of the wavelength of the sound waves produced by a tuning fork vibrating over one end of the pipe that's open to the air at both ends.
