The product of wavelength and frequency is always the
speed of the wave.
For this particular wave,
Speed = (2 meters) x (6 per second) = 12 meters per second .
Answer:
Explanation:
A lot of physicist and many cosmologist believe by their research works on quantum fluctuation that it is possible for the universe to be created out of nothing. They believe and has almost proved that particle comes in and out of existence from empty space. This idea led them believe that big bang singularity also came out of nothing (hyperspace) by quantum fluctuation creating positive and negative energy of equal amount. Thus conserving law of energy. In this scenario, positive energy is matter and negative energy is gravity so total energy of universe/big bang singularity is zero. Therefore, it is plausible for our universe to come out of nothing on its own. But why universe came into existence it's own confirming the idea of 'why there is something rather than nothing' as Lawrence Maxwell Krauss hypothesized could be correct.
Answer:
18375g
Explanation:
Let's find the volume of the rectangular block.
Volume
= length ×breadth ×height
= 3.5 ×6 ×2.5
= 52.5cm³
Mass of the block
= 350(52.5)
= 18375g
Answer:
Density is determined by an object's mass and volume.
Explanation:
If two objects take up the same volume, but one has more mass, then it also has a higher density.
