Two ice skaters stand next to each other on a frozen pond. The first skater has a mass of 65 kg and the second skater has a mass of 82 kg. If the first skater pushes against the second with a force of 35 N, south, what are their respective

accelerations?

A. First skater: 0. 27 m/s2, north; Second skater: 0. 21 m/s2, south

B. First skater: 0. 27 m/s2, south; Second skater: 0. 21 m/s?, north

C. First skater: 0. 54 m/s2, north; Second skater: 0. 43 m/s2, south

D. First skater: 0. 54 m/s2, south; Second skater: 0. 43 m/s?, north

Answers

Answer 1

Their respective accelerations are D: First skater: 0.54 m/s², south; Second skater: 0.43 m/s², north.

How to calculate acceleration?

To solve this problem, use the formula F = ma, where F = force applied, m is the mass of the skater, and a is the acceleration.

First find the acceleration of the first skater. The force is 35 N, south, and the mass is 65 kg.

F = ma

35 N = 65 kg × a

a = 35 N / 65 kg

a = 0.54 m/s², south

So the first skater has an acceleration of 0.54 m/s², south.

Now find the acceleration of the second skater. The force is the same 35 N, south, but the mass is 82 kg.

F = ma

35 N = 82 kg × a

a = 35 N / 82 kg

a = 0.43 m/s², south

So the second skater has an acceleration of 0.43 m/s², south.

Therefore, the answer is option D: First skater: 0.54 m/s², south; Second skater: 0.43 m/s², north.

Traveling through a wormhole transports an individual to another location in spacetime. option D

Why would this happen?

These hypothetical tunnels could join far-off points within the vast universe or even distinct universes, as predicted by Einstein's general theory of relativity.

Although entering one is largely speculative and mysterious, it would likely induce rapid acceleration and resultant temporal shifts, possibly causing time dilation among other relativistic phenomena.

The journey's precise nature depends on unique attributes intrinsic to the wormhole as well as external circumstances relevant throughout traversal.

The test statistic based on the information will be option C.

How to explain the information

It should be noted that to test the hypothesis the most appropriate test is two independent samples t-test (unequal population variances) for mean.

Where, x1, x2 are sample mearns, s1, s2 are sample standard deviations and n1, n2 are sample sizes.

We are given the following informations :

x1 = 4.05, x2 = 3.99

s1 = 0.039, s2 = 0.025

n1 = 61, n2 = 61

Hence the test statistic will be Option C.

Answers

The correct answer is D. You would end up in another point in spacetime.

A wormhole is a hypothetical tunnel-like structure that connects two separate points in spacetime. If you were to pass through a wormhole, you would essentially be taking a shortcut through spacetime, allowing you to travel vast distances in a shorter amount of time.

The concept of a wormhole is purely theoretical, and there is currently no experimental evidence to support the existence of wormholes. However, if wormholes do exist, passing through one would likely result in you ending up in another point in spacetime, potentially in a different part of the universe or even a different universe altogether. The experience of passing through a wormhole is purely speculative, and there is no scientific consensus on what would actually happen.
