The horizontal force is m*v²/Lh, where m is the total mass. The vertical force is the total weight (233 + 840)N.
<span>Fx = [(233 + 840)/g]*v²/7.5 </span>
<span>v = 32.3*2*π*7.5/60 m/s = 25.37 m/s </span>
<span>The horizontal component of force from the cables is Th + Ti*sin40º and the vertical component of force from the cable is Ta*cos40º </span>
<span>Thh horizontal and vertical forces must balance each other. First the vertical components: </span>
<span>233 + 840 = Ti*cos40º </span>
<span>solve for Ti. (This is the answer to the part b) </span>
<span>Horizontally </span>
<span>[(233 + 840)/g]*v²/7.5 = Th + Ti*sin40º </span>
<span>Solve for Th </span>
<span>Th = [(233 + 840)/g]*v²/7.5 - Ti*sin40º </span>
<span>using v and Ti computed above.</span>
Answer:
The second answer from the top, no the energy in the wave pushed the water particles from above the earthquake in the opposite direction.
Explanation:
I believe this is the correct answer. Hope you do well
The true scientific way is the last: using the water displacement method
Answer:
Protons and electrons are charged particles. Neutrons have no charge.
Answer:
The white dwarf will start to get darker.
Explanation:
The white dwarf will keep is spherical shape, since electron degeneracy pressure (outward direction) will counteract the force of gravity due to its own mass (inward direction) which lead to hydrostatic equilibrium.
A nuclear reaction occurs when light elements combine into heavier elements (that is know as nucleosynthesis). Exist different ways in which that can happen, but the most common is the Proton-Proton chain. In that fusion reaction, two atoms of Hydrogen combine to form helium, while the fusion takes place, photons are created.
Photons are the elementary particles that constitute light and taking into account that in white dwarfs the production of photons has ceased because there are no nuclear fusions, then, it is clear that the white dwarf will start to get darker as it cools since is emitting into space the photons produced in the past.
