Albert is on earth and measures the speed of light from the sun as 3 e8 m/s. he then gets in a spaceship and speed toward the sun at 1 x e8 m/s. he will then measure the speed of light as 2 e8 m/s 3 e8 m/s 4 e8 m/s none of the above

The speed of light remains the same.

Explanation:

It is given that, Albert is on Earth and measures the speed of light from the sun as 3 × 10⁸ m/s. He then gets in a spaceship and speed toward the sun with a speed of 1 × 10⁸ m/s.

In this case, the speed of light remains the same i.e. 3 × 10⁸ m/s. It is a universal constant. Albert Einstein was the first scientist who has written his first research paper on relativity. According to him, the speed of light remains the same. It does not depend on how fast the observer moves.

Hence, the correct option is (b).

1.195000

explanation:

total mass=0.0117+0.0137+0.0881+0.0111

total mass= 0.01172kg

total velocity = 0.283-0.743+0.871-0.799+0.155+0.637+0.301=0.102

momentum=mv=0.1172*0.102=1.195000//
