15) The diagram below represents the sequence of events (steps 1 through 10) resulting in the production of a D' meson and a D*
zubka84 [21]

A statement which describes the changes that occur in this sequence of events is: 2. matter is converted into energy and then energy is converted into matter.

<h3>What is the law of conservation of matter?</h3>

The law of conservation of matter (LOCOM) states that mass can neither be created nor destroyed in any chemical reaction.

Similarly, the energy possessed by a matter can neither be created nor destroyed, but it can only be converted from one energy form to another.

In this context, we can logically deduce that a statement which best describes the changes that occur in this sequence of events is that matter is converted into energy and subsequently, energy is converted into matter.

a child is swinging on swing, describe what happens to both the kinectic energy and potential enegry of the child as she swings
Igoryamba

Answer:

The K.E is maximum when the child is at the vertical position and the P.E is maximum at the extreme deviated position from the vertical.

Explanation:

  • A child is swinging on swing up and down has both kinetic and potential energy.
  • The total mechanical energy of the system is conserved throughout the system. At any instant the total mechanical energy is given by,

                                      E = K.E + P.E

  • The K.E is maximum when the child is at the vertical position.
  • The P.E is maximum at the extreme deviated position from the vertical.
  • And when K.E is maximum P.E becomes minimum and vice versa as per the law of conservation of energy.

If you are standing at Earth’s North Pole, which of the following will be directly overhead?
Sidana [21]

The north celestial pole (and also the south) are described as two imaginary points that project on the axis of rotation of the earth, indefinitely towards space and that intersects with the celestial sphere (Remember that the earth has a slight inclination with respect to to its axis of rotation). The north and south celestial poles are directly above the head of someone located at the north or south pole of the earth.

Correct Answer is A.
