Answer
given,
F₁ is horizontal = 40 N
F₂ is normal = 20 N
F₃ is parallel = 30 N
work done by
W₂ = 0 as force is acting perpendicular to the direction of motion.
as the motion moved to 0.8 cm
W₃ = F₃ x d
W₃ = 30 x 0.8
W₃ = 24 J
W₁ = F₁ x d
W₁ = F₁ cos ∅ x d
W₁ = 40 cos 30⁰ x 0.8
W₁ = 27.21 J
Nuclear decay is spontaneous.
Nuclear fission does occur spontaneously but at a
very low level in fissionable materials. The main difference between fission
and nuclear decay is that fission can occur by neutron bombardment. And when
the neutron source is also other fissioning atoms, a chain reaction can may
happen. <span>
No chain reaction is possible with nuclear decay.
<span>That would be a much better characteristic to look at.</span></span>
The answer for this question would be option A) TRUE or the first choice because one's perception DOES depend on the way the brain interprets the stimuli.
A tsunami wave is different than a normal wave because it is caused by an sudden displacement in the ocean. a earth quake below the ocean floor, a landslide, or a meteorite impact. normal waves are caused by the wind, weather and tides, unlike tsunamis. the long wavelengths from the impact from a earthquake can make the wave slow down and increase the amount of water + height for the wave, making a larger impact wave, a tsunami
It depends where its saying this. If its and advertisment then the purpose is to use health facts in order to persuade the reader to buy the fruit drink,if its in an artical then probably someone with a bias against soda is trying to convince you to switch to drinking fruit juice.
