Imagine that a star-forming cloud collapses but retains all of its mass in a single blob. In order to conserve angular momentum, the cloud must spin faster.

Conservation of angular momentum is a physical characteristic of a rotational system that keeps its rotation constant unless it is affected by an external torque. In other words, the speed is constant as long as the net torque is zero.

In angular kinematics, conservation of angular momentum refers to the tendency of the system to preserve angular momentum in the absence of external torque. If the objects collide without net external torque, the angular momentum is constant. The two objects exert equal but opposite angular momentums to maintain the full angular momentum of the colliding system.

In the visible spectrum, red light has the lowest frequency and violet light has the highest. List the following colors in order
dalvyx [7]
The correct answer is:
<span>B) orange, yellow, green, blue 

the energy of the photons of light is directly proportional to the frequency of the light. This means that the lower the frequency, the lower the energy, and the higher the frequency, the greater the energy. 

Therefore, the order in increasing energy  is exactly the same as the order in increasing frequency, which is:

How high off the ground must you be if you mass is 75 kg and you have 11,025 J of energy stored inside?
pashok25 [27]

Answer:

15 m

Explanation:

Given,

Mass ( m ) = 75 kg

Potential energy ( P.E ) = 11,025 J

To find : Hight ( h )

Formula : -

P.E = mgh

[ Note : The value of g = 9.8 m/s² ]

h = P.E / mg

  = 11,025 / ( 75 x 9.8 )

  = 11,025 / 735

h = 15 m

Hence,

15 m is the high off the ground must you be if you mass is 75 kg and you have 11,025 J of energy stored inside.

Which one of the following materials would provide the most electrical resistance?
Lena [83]

Glass is the material that would provide the most electrical resistance.  

Elements which are good conductors of electricity are referred to as

Metals. They usually have low resistance.

<h3> Examples of Metals</h3>
  • Copper wire
  • Aluminium

Non metals are are low conductors of electricity and have high resistance.

Electrolytes such as salt water are also good conductors of electricity.

Glass are generally regarded as Insulators and are poor conductors of

electricity which makes it the material with the most electrical resistance.
