A wire is stretched to double its length .what happened to its resistance and resistivity?​

Physics

Resistivity of wire remains constant. As the length of wire gets doubled, the cross-sectional area will become half of its previous value because volume of wire remains constant. Hence, we can see that the new resistance is four times the previous resistance.

svet-max [94.6K]
<h3><u>Solution</u><u>:</u></h3>
  • Distance (d) = 112 m
  • Time (t) = 4 seconds
  • Let the speed be v.
  • We know, speed = Distance / Time
  • Therefore, v = d/t

or, v = 112 m ÷ 4 s = 28 m/s

<h3><u>Answer</u><u>:</u></h3>

<u>The </u><u>speed </u><u>of </u><u>the</u><u> </u><u>cheetah</u><u> </u><u>is </u><u>2</u><u>8</u><u> </u><u>m/</u><u>s.</u>

Saturn exerts a much greater force on the moon Pan than Pan exerts on saturn. true or false
shtirl [24]

Answer: False

Explanation:

because according to universal law of gravitation, every object attracts every other object in the universe.

according to the newton's third law, for every action there is equal and opposite reaction.

So, both the saturn and pan exerts same force on each other

But from the newton's second law we have, F = ma   &   a = F/m

so, from the above equation acceleration produced by pan is high compared to the acceleration produced by saturn.

Therefore, acceleration produced by saturn is lower than the acceleration produced by pan

but force exerted by saturn is equal to the force exerted by pan

So, the answer is false
