  • Height=h=102m
  • Mass=m=120g
  • Acceleration due to gravity=g=10m/s^2

\\ \sf\longmapsto P.E=mgh

  • P E means potential energy

\\ \sf\longmapsto P.E=102(120)(10)

\\ \sf\longmapsto P.E=122400J

Since nuclear fusion in the sun creates energy from matter, why doesn't it violate the law of conservation of energy?
alexandr402 [8]

Since nuclear fusion in the sun creates energy from matter, Einstein's formula E=mc² states that matter and energy are equal.

To find the answer, we have to know more about the nuclear fusion.

<h3>What is nuclear fusion?</h3>
  • We are aware that the sun can achieve nuclear fusion by the fusion of hydrogen atoms.
  • These atoms need to get closer to one another in order to fuse.
  • Since both protons inside each nucleus are positively charged, they attempt to repel one another as they get closer to one another.
  • If this issue cannot be solved, nuclear fusion in the sun cannot occur.

Thus, we can conclude that, since nuclear fusion in the sun creates energy from matter, Einstein's formula E=mc² states that matter and energy are equal.

it takes 29.5 minutes to walk with an average velocity of 1.2 m/s to the north from the bus stop to the museum entrance what is
olasank [31]

Displacement is distance moved,so if you have your velocity in m/s you need your total time in seconds and multiply the two to get displacement so at 1.2m/s travelling (9.5*60(60seconds in a minute)=570 seconds is 570*1.2=684

What type of volcano only ever has quiet eruptions?
77julia77 [94]
In contrast to quiet eruptions, other volcanoes erupt explosively. Mount St. Helens, for instance, spewed lava high in the air when it erupted. Two things control the type of eruption: how much water vapor and other gasses are in the magma and whether the magma is basaltic or granitic. Basaltic magma tends to ooze out gently in a thin, quiet eruption, while granitic magma is thicker and becomes trapped inside the volcano's vents. Once the pressure grows enough to force out the magma, it explodes.
