Which evidence is lost likely used to indicate the beginning of solar system formation?

Physics
1 answer:
deff fn [24]4 years ago
7 0

Explanation :

Our solar system was formed about 4.6 billion years ago. It is formed when gravity exerted low-density cloud of interstellar gas and dust. The massive cloud of gas and dust is called as Orion Nebula.  

In a small area, the overdensity of clouds occurs. This caused the contraction, to begin. Due to this contraction the potential energy gets converted into kinetic energy of individual gas particles.

Hence the correct option is " materials were pulled together by the gravity". This is the one of the evidence used to indicate the beginning of the solar system.

A bird has kinetic energy of 3 J and the potential energy of 25 J what is the mechanical energy of the bird 3 J Because mechanic
tiny-mole [99]

Answer:

The total mechanical energy of the bird is, E = 28 J

Explanation:

The total mechanical energy of the system is the sum of the potential and kinetic energy of the system.

When a bird is flying at a certain height from the ground, it posses partial potential and kinetic energy.

The total energy,

                                           E = P.E + K.E

                                           P.E = mgh J

                                           K.E = ½ mv²

The total mechanical energy of the bird at any instant of time is equal to its potential and kinetic energy.

Hence, the mechanical energy of the bird is, E = 25 J

Why a steel ship becomes magnetized as it is constructed?
Inessa [10]
<em>Iron, and to a lesser degree, steel, can only become magnetised by passing an electrical current through it (an electromagnet). So a steel ship does not become magnetised in the accepted sense during construction. </em>

<span><em>However, any large mass of iron will affect the accuracy of a magnetic compass, causing it to deviate wildly from magnetic North. This problem was encountered when iron ships were first constructed in the mid-19 Century. It was overcome by mounting the compass in a 'binnacle', a housing containing two large soft iron balls either side of the compass itself, which counteracted the effect of the hull and balanced the compass so that it read correctly</em></span>

During the time that the blocks are in contact, describe whether the center of mass of the two-block system is speeding up, slow
iVinArrow [24]

Answer:

The center of mass of the two-block system is staying the same and it can be explained with the help of linear momentum equation.

Explanation:

The center of mass of the two-block system is staying the same and it can be explained with the help of linear momentum equation.

Equation:

P=mv

This equation holds if no external force is acting on the system it means the momentum of the system is constant.

In our case, there is no external force which means the total momentum of system is constant:

P=constant

Total mass of system is also constant:

m=constant

It means the velocity of the system is constant (from above equation) thus center of mass of the two-block system is staying the same
