<span>P= work/time and work is = to force x distance so its 500x4 =2000joules
and 2000/4 =500 watts</span>
Answer:
f_tympanum = 256 Hz.
Explanation:
The eardrum is the vibrating membrane of the human ear, it works by resonance, that is, an external stimulus (force) makes it vibrate, as the eardrum is extremely light it can vibrate at the same frequency of the incident sound.
Consequently if the incident vibration is f = 256 hz, the eardrum resonates at the same frequency
f_tympanum = 256 Hz.
As a reference the response of the eardrum goes from f = 20 Hz f = 20000 Hz
Answer:A) he needs to find the net force acting on an object in a direction.
Explanation:
Properly input current above 40 voltage or 100 for example elecrical fan machine is used to perform a task, work output is always more than work
172 + 115 cos 31 +115 cos 48 horizontally
115 sin 31 - 115 sin 48 vertically
possibly need some drawing
