Abolt is threaded onto one end of a thin horizontal rod, and the rod is then rotated horizontally about its other end. an engineer monitors the motion by flashing a strobe lamp onto the rod and bolt, adjusting the strobe rate until the bolt appears to be in the same eight places during each full rotation of the rod. the strobe rate is 2000 flashes per second; the bolt has mass 50 g and is at radius 3.5 cm. what is the magnitude of the force on the bolt from the rod?

hello from mrbilldoesmath!

answer:

the domain is the set { -2, 0, 2, 3}

discussion:

the domain is the set of x values in the ordered pairs (x,y). taking the x, or first component, of each ordered pair gives   -2, 0, 2, 3.

answer would be 8.64 or s = 11π/4 inches

step-by-step explanation:

s = r θ  

where s = arc length  

r = radius = 3 inches  

θ = central angle in radians = ( π /180)*165  

s = 3(π/180)*165  

= 8.64 inches

you go to prefence in the settings and youll see a "i want to delete my account.
