Answer:
When two balls are raised from one end and released, they strike the row and two balls pop out from the other end. If instead, one ball popped out with twice the speed of the two, this would violate <u>law of conservation of energy</u>.
Explanation:
"According to law of conservation of energy, energy can neither be created nor destroyed it only changes it's states."
we can prove it as
the initial momentum = 2mv
if one ball popped out with 2v then the momentum would be conserved.
But the initial kinetic energy of these two balls are given as
but if the speed of one ball is twice then that of other one then the kinetic energy won't remain conserved.
thus it violates the law of conservation of energy.
Answer:
The answer is "Speed".
Explanation:
In the question, the Speed is the correct answer because it can be viewed as its rate from, which a length is covered via an object. It is also divided by time into other components of distance. Its SI unit of speed seems to be the meter/second, but still, the kilometer/hour or, in the Us UK, miles per hour is the most basic fundamental of speed in everyday use.
The electrical is dominant.
In the hydrogen atom, the electrical force is vastly stronger than the gravitational. It is roughly 39 orders of magnitude greater, i.e. ratio of the electrical to gravitational force is on the order of 10^39.
Answer:
the statement is true
Explanation:
The bonds in the molecules give rise to irrational energy levels, are quantized, that is, they are discrete
In order for a photon to create a transition between the given levels it has to have the same energy as these two levels, it is in this case if the photon has the energy of the bond can be promised to the electron and be absorbed.
In summary the statement is true
Answer:
Energy transformation is when energy changes from one form to another – like in a hydroelectric dam that transforms the kinetic energy of water into electrical energy. While energy can be transferred or transformed, the total amount of energy does not change – this is called energy conservation.
