Physics
1 answer:
Pachacha [2.7K]3 years ago
5 0

Answer and Explanation:

The binary system is a star system about half of the star are the part of the binary system

The important binary systems are

  • Visual binary : in visual binary system the two stars resolved visually with nay sort of optical device the orbit of binary orbit is very large about center of mass.
  • Spectroscopic binary : in this binary system the stars are detected by close analysis of light and after detection it is found that there are two seller spectrum present instead of one.
  • Eclipsing binary : eclipsing binary system is a several types of variable stars this binary system is very important in astrophysics

A plastic box has an initial volume of 2.00 m 3 . It is then submerged below the surface of a liquid and its volume decreases to
nikitadnepr [17]

Answer:

Volume strain is 0.02

Explanation:

Volume strain is defined as the change in volume to the original volume.

It is given that,

Initial volume of the plastic box is 2 m³

It is then submerged below the surface of a liquid and its volume decreases to 1.96 m³

We need to find the volume strain on the box. It is defined as the change in volume divided by the original volume. So,

\delta V=\dfrac{V_f-V_i}{V_i}\\\\\delta V=\dfrac{1.96-2}{2}\\\\\delta V=0.02

So, the volume strain on the box is 0.02.

Jane, looking for tarzan, is running at top speed (5.2 m/s) and grabs a vine hanging 4.5 m vertically from a tall tree in the ju
kumpel [21]
While Jane is running has a kinetic energy, which is Ek = 1/2*m*v^2 where m is mass and v is velocity  When she grabs a vine, she is going to change the kinetic energy to potential energy.  
We know that potential energy is given by Ep = m*g*h where m is mass, g is gravity constant and h is height  
So while running the kinetic energy is Ek = 1/2 * m * 5.2^2 = 13.52*m 
Then all that energy is used to swing upward and gain potential energy 
Ep = m*g*h = Ek = 13.52*m  
m*9.8*h = 13.52*m 
h = 13.52/9.8 = 1.38 meters  
So Jane will swing 1.38 meters upward

Imagine that you are an industrial worker in a city in China. What would you put in an e-mail to a relative in the United States
Mumz [18]

In that email, I will tell my relative in the United states that the transition to capitalism now implies that we work for longer hours with less pay.

<h3>What is capitalism?</h3>

The term capitalism means a system in which the means of production is controlled by individuals rather than by the state. Hence, monopoly is possible in a capitalist economy.

In that email, I will tell my relative in the United states that the transition to capitalism now implies that we work for longer hours with less pay and we do not have the social and job security that was once guaranteed in a socialist/communist economy.
