As we know that centripetal acceleration is given as
here we know that
linear speed = 35 m/s
here radius of path is same as length of arm
R = 0.7 m
now from above above formula we have
so acceleration is 1750 m/s/s
<span>As long as both mirrors are set at 45% and the same size then you see the same as is reflected in the upper mirror </span>

<span>? </span>
<span>We use mirrors when we drive cars ect </span>
<span>Normally they are set across from a concealed entrance or one that is hard to see both ways like the inside of a hairpin bend. Sometimes only to help in one direction. </span>
<span>Sonar which is sound waves that are sent out at a set rate then reflected by objects. The longer the gap between the two the further away it is, They still use periscopes to target boats though. </span>
<span>The periscope can only reflect what is outside so if you could see it because there is enough light then Yes. If you could not see it because it is dark then No unless you get into Info-Red light or Image Intensifying systems as well </span>

Answer: D) none of the above
Explanation: This is a classic problem of thermodynamics, and refers to the principle of conservation of energy to give a correct answer
Option A) can be ruled out since no matter how much friction is reduced, it will always exist and therefore some energy will be lost
option B) and C) are out of context since the loss of work or energy will continue to exist even if those values are modified, so they do not answer the question
D) is the correct one since it should be said that this is not possible (so far...) as it goes against the conservation of energy and this option is none of the above
