3.8 x1017 is the correct answer
never [62]3 years ago
3 0

Answer:

3.8 x 10¹⁷ in

Explanation:

Light speed= 982,080,000 ft/s

year(time)= 32,000,000 seconds

converting ft/s to in/s for the speed of light:

1ft/s = 12 in/s

982,080,000 ft/s x 12in/s = 11,784,960,000 in/s ( speed of light in inches)

using the standard formula for speed:

V=\frac{Distance}{Time}

Distance( inches)= V (speed in/s) x Time (seconds)

Distance = 11,784,960,000 x 32,000,000

Distance≅ 3.8 x 10¹⁷ in

What is the net force on a cart that is pulled to the right with 100 pounds of force and to the left with 30 pounds of force?
Arlecino [84]

Answer:

The answer to your question is: F = 70 pounds

Explanation:

To calculate the net force, only substract the left value to the right value.

                                F = F right  -  F left

                                F = 100 p - 30 p

                                F = 70 pounds
