Juliette [100K]

Answer:

None of the stars give of light that is red-shifted

Explanation:

Motion of the observer or the source will cause a change in the wavelength of a wave. This is known as the Doppler effect. When an object and observer are getting close, blue shift occurs i.e., the wavelength gets shorter. When an object and observer are getting farther red shift occurs i.e., the wavelength gets longer.

Here, both the stars are getting closer to us so blue shift will occur.

Calculate the Work done if the force is 2000 Newtons<br> and the distance is 5 km.
kodGreya [7K]

Answer:

10 million joules or 10,000 KJ

Explanation:

Work= Force x Displacement

convert 5km into meters -5km=5000m

W= 2000N x 5000m

w=10,000,000 Joules

or 10,000KJ

What is the difference between a homogeneous mixture and heterogeneous mixture?
Semenov [28]
Homogenous mixtures don't have visible constituents. An example of this would be water.

Heterogenous ones have visible constituents and an example would be if you put some dirt in water and then it wouldn't mix properly and you could see the dirt in it.

An electrical short cuts off all power to a submersible diving vehicle when it is a distance of 28 m below the surface of the oc
skelet666 [1.2K]

Answer:

F=126339.5N

Explanation:

to find the necessary force to escape we must make a free-body diagram on the hatch, taking into account that we will match the forces that go down with those that go up, taking into account the above we propose the following equation,

Fw=W+Fi+F

where

Fw=   force or weight produced by the water column above the submarine.

to fint Fw we can use the following ecuation

Fw=h. γ. A

h=distance

γ= specific weight for seawater = 10074N / m ^ 3

A=Area

Fw=28x10074x0.7=197467N

w is the weight of the hatch = 200N

Fi is the internal force of the submarine produced by the pressure = 1atm = 101325Pa for this we can use the following formula

Fi=PA=101325x0.7=70927.5N

finally the force that is needed to open the hatch is given by the initial equation

Fw=W+Fi+F

F=Fw-W+Fi

F=197467N-200N-70927.5N

F=126339.5N
