Answer:
B) Bb × Bb I think I can't promise that's right
When a match stick is struck, some of the chemical energy is transformed into heat and light and the rest is converted into matter. A match stick has a lot of chemical energy stored in it. When its struck, It start burning. The chemical energy stored in it is transformed into heat energy and light energy. The rest of it turn into ashes and reaction gases.
Hi there!
The energy that is about to or can be released from an object after energy has been transferred to it is called potential energy. In this case, as the diver jumps, potential energy is stored in the board as it bends. The potential energy is then released as kinetic energy when the board springs back up and the diver actually jumps.
Hope this helps!
Honed I don’t know where the question is
Answer:
To the right relative to the original frame.
Explanation:
In first reference frame <em>S</em>,
Spatial interval of the event,
Temporal interval of the event,
In the second reference frame <em>S'</em>, the two flashes are simultaneous, which means that the temporal interval of the event in this frame is
The speed of the frame <em>S' </em>with respect to frame <em>S</em> = v.
According to the Lorentz transformation,
And positive v means the velocity of the second frame<em> </em><em>S'</em> is along the positive x-axis direction, i.e., to the right direction relative to the original frame <em>S</em>.
