That states that the blackhole ends are working like bridges between one space to another.

  • And you can travel through them in 5-10s
  • The distance is thousands of lightyears but we can travel it..

This may be possible

a0.155 kg arrow is shot from ground level, upward at 31.4 m/s. what is its kinetic energy (ke) when it is 30.0 m above the groun
swat32

The kinetic energy (KE) of a 0.155 kg arrow that is shot from ground level, upward at 31.4 m/s, when it is 30.0 m above the ground is 30.85 J

Assuming air friction is negligible,

a = - 9.8 m / s²

u = 31.4 m / s

s = 30 m

v² = u² + 2 a s

v² = 31.4² + ( 2 * - 9.8 * 30 )

v² = 985.96 - 588

v² = 397.96 m / s

KE = 1 / 2 m v²

KE = 1 / 2 * 0.155 * 397.96

KE = 0.0775 * 397.96

KE = 30.85 J

Therefore, the kinetic energy ( KE ) when it is 30.0 m above the ground is 30.85 J

What happens when a car that weighs 300 lbs. driving at speeds of 80 mph collides with a bystander that weighs 180 lbs.
EleoNora [17]

Answer:

Basically, at these speeds, the car will, at random times, swerve a bit to one side or the other as if hit by some huge wind (even on the calmest of days). It doesn't happen at slower speeds driving mechanically identical cars, managed to accelerate to a formidable 150 mph and stay there for most of the journey, shifting to higher gears and remaining.

Hope this helped you!

It takes a car 1.75 h to go from mile marker 10 to mile marker 115. What is the average speed of the car? Someone who took this
givi [52]

The distance from mile-mark 10 to mile-mark 115 is (115-10) = 105 miles.

Speed = (distance covered) / (time to cover the distance) .

Speed = (105 miles) / (1.75 hours)

Speed = (105/1.75) (mi/hr)

<em>Speed = 60 mph</em>  (B)

A tree is 257 ft high. To the nearest tenth of a meter, how tall is it in meters? There are 3.28 ft in 1 m.
olga2289 [7]

Answer:

Height of tree = 78.35 meters.

Explanation:

We have

          1 meter = 3.28 feet

That is

          1 ft = \frac{1}{3.28}=0.3048m

Here height of tree = 257 ft

Height of tree = 257 x 0.3048 = 78.35 m

Height of tree = 78.35 meters.
