An alien spaceship 8x10^14m away sends us a radio wave signal. How long does it take for the signal to reach us?
Nata [24]
Time = distance/speed

Time = 8•10^14m / 3•10^8m/s

Time = about 2.7•10^6 seconds.

A uniform plank of length 6.1 m and mass 33 kg rests horizontally on a scaffold, with 1.6 m of the plank hanging over one end of
salantis [7]

Answer:

Explanation:

consider the principle of moment

when a system is in equilibrium, the clockwise moment (torque) about the pivot is equal to the counterclockwise moment ( torque). Since the plank is uniform the weight of the plank act at the middle which = 6.1 m / 2 = 3.05 m

the distance that can support the weight of the man = d

mass of the man = 70

70 × d = 33 × ( 3.05 - 1.6)

d = 47.85 / 60 = 0.798 m, if the man work beyond this point he will fall.
