An astronaut awakes in her closed capsule, which actu- ally sits on the Moon. Can she tell whether her weight is the result of g

ravitation or of accelerated motion? Explain.

Answer:

No, she cannot tell due to the theory of the relatively.

Explanation:

As for this to happen the capsule has to be of constant acceleration in order to move without being noticed.

If the capsule slows down the speed would be reduced and the gravitation effects would be seen and another way would be for the capsular to spin constantly and have an acceleration motion of the outwards direction.

As the capsule would have to the fairly small size and thus create a strong feeling of the gravity.

Because those places want a secure population and don't want to over populate so u are only allowed to have 2 kids I believe but that always change plus kids go to war and kids are getting killed

A bandleader randomly select's 2 students out of 100 band members. if you and your brother are both bandmembers what is the prob

sladkih [1.3K]

Probability of an event happening=(numbers of ways it can happen) / (total numbers of outcomes)

P=probability that we are both selected
P₁=probability that I am selected and my brother is selected after.
P₂=probability that my brother is selected and I am selected afer.

P=P₁+P₂

P₁=(1/100)*(1/99)=1/9900
P₂=(1/100)*(1/99)=1/9900

P=1/9900 + 1/9900=2/9900≈0,0002≈0.02%

solution: P=2/9900≈0.02%

6. What is the velocity of deep-water waves that have a wavelength of 46 meters and a wave period of

BlackZzzverrR [31]

Answer:

velocity = 7.30 m/sec

23 m depth wave will feel bottom

Explanation:

given data

wavelength = 46 meters

wave period = 6.3 second

to find out

velocity and At what water depth will a deep water wave begin to feel bottom

solution

we get here velocity that is express as

velocity = $\frac{wave\ length}{wave\ period}$ .............1

velocity = $\frac{46}{6.3}$

velocity = 7.30 m/sec

and

wave base = $\frac{1}{2}$ × wavelength .................2

wave base = $\frac{1}{2}$ × 46

wave base = 23 m

here water depth more than 23 m will producer will circular wave less than elliptical wave

so 23 m depth wave will feel bottom
