Abulldozer drags a log weighing 500 n along a rough surface. the cable attached to the log makes an angle of 30 degrees with the ground. the coefficient of static friction between the log and the ground is 0.500. what is the minimum tension required in the cable in order for the log to begin to move?

answer: the correct answer id option(d).

explanation:

snell's law refraction:

the angle of refraction =

the angle of incidence =

refractive index of air = = 1

refractive index of glycerol = 1.47

from the given options, the most closest answer to 63.72° is 65° of option (d).

false

explanation:

boats, things on boats luggage are way more heavy then water.
