Answer: The correct answer is "the wavelength will get shorter".

Explanation:

Red shift: In red shift, Light changes as the object in space (such as galaxies or stars) moves away from us then the light is shifted to red end. In this case, the light is shifted to longer wavelength.

Blue shift: In blue shift, Light changes as the object in space (such as galaxies or stars) moves towards from us then the light is shifted to blue end. In this case, the light is shifted to shorter wavelength.

In the given problem, the object moves towards us, then the wavelength of the object gets shorter.

\sqrt{2}Answer:

KE2 = 2 KE1

1/2 M V2^2 = 2 * (1/2 M V1^2)

V2^2 = 2 V1^2

V2 = \sqrt{2} V1

Since momentum = M V  the momentum increases by \sqrt{2}

Scorpion4ik [409]

Answer:

Explanation:

Writers periodically compete to see who can write the longest sentence in literature. James Joyce long held the English record with a 4,391 word sentence in Ulysses. Jonathan Coe one-uped him in 2001 with a 13,955 word sentence in The Rotter’s Club. More recently, a single-sentence, 469,375 word novel appeared.Writers periodically compete to see who can write the longest sentence in literature.

The weight of a body of certain mass becomes zero in space.why?write with reasons​
Anvisha [2.4K]

Answer:

Weight is what you get when a certain amount of gravity is acting on that mass, and something, like the surface of a planet, is resisting that action. In space, when falling freely, there's nothing resisting the pull of gravity so weight disappears. Mass however stays.

Zigmanuir [339]

Answer: The work is 1863 N*m

Explanation:

We can define work as:

W = F*d

Where F is the force that the mover needs to apply to the refrigerator, and d is the distance that the refrigerator is moved.

To move the refrigerator, the minimal force that the mover needs to do is exactly the friction force (In this case, the refrigerator will move with constant speed).

Then we will have:

F = 230 N

and the distance is 8.1 meters, then the work will be:

W = 230N*8.1 m = 1863 N*m
