Answer:

1 light year= 9.5 trillion km

Explanation:

Light year is distance traveled by light in one year.

Distance =  speed x time = speed of light x 1 year

1 light year= 3 x 10⁸ x 365 x 24 x 60 x 60 = 9.5 x 10¹⁵m=9.5x 10¹²km

1 light year= 9.5 trillion km

Luba_88 [7]

Answer:

F = 4399 KN

Explanation:

given,

mass of automobile = 890 kg

initial speed = 48 km/h

                     = 48 × 0.278 = 13.34 m/s

using equation of motion

v² = u² + 2 a × s

0 = 13.34² - 2 a ×0.018

a = \dfrac{13.34^2}{0.036}

a = 4943.21 m/s²

F   = m × a

F   = 890 × 4943.21

F   =  4399456.9 N

F = 4399 KN

hence, the  Net force is F = 4399 KN

How are tensional forces created?
dezoksy [38]
Tensional forces are created on a piece of string or rope or anything similar when it is pulled tight from both sides, that is, when forces are acting on both ends, thus tightening it. <span>The tension force is directed along the length of the wire and pulls equally on the objects on the opposite ends of the wire.</span>
