In order to have a verified or reliable answer to this question, they should take the watch apart and test the mechanism to see what causes failure.

Answer: Option D

<u>Explanation: </u>

For dropping a similar watch to record results, we need to buy another one. So, it becomes expensive. And, calling the manufacturer will give accurate results, but no knowledge. It is like getting multiple choices by luck.

Consulting senior faculty won’t result in any progress, because they may not have conducted these. So, one should rip off the watch, and study the mechanism, and its limitations.  The testing of mechanism gives the actual results.

Answer: B) Drop a similar watch multiple times and record the results.

Explanation:

In order to have a verified or reliable answer to this question, investigators must drop a similar watch multiple times and record the results. By doing this and repeatedly getting the same result(s), they are able to determine that their answer is in fact true.

How can the rate of a reaction be increased?
olya-2409 [2.1K]
<h3><u>Answer and explanation;</u></h3>

-Rate of reaction is the speed at which the reactants are converted to products.

-Rate of reactions depends on a number of factors which includes<u>;</u>

  • <em><u>Concentration of reactants</u></em>;<u><em> increasing the concentration of reactants</em></u> increases the rate of reaction.
  • <u><em>Temperature;</em></u><u><em> </em></u>An <u><em>increase in temperature results to an increased rate of reaction.</em></u> Increase in temperature increases the kinetic energy of molecules thus the collision per unit time also increases and hence the rate of reaction increases.
  • <u><em>Decreasing the size of particles of solid reactants</em></u> also increases the rate of reaction. This is because smaller particles increases the surface area on which more collisions can occur thus a faster rate of reaction.
  • <em>Adding a catalyst also increases the rate of reaction.</em> This is because catalysts lower the activation energy of reactants, minimum energy require by reactants for the reaction to take place. This thus increases the rate of reaction.

sergeinik [125]

The force of gravity increases with an increase in the mass of objects. . . . A large, massive dog weighs more than a small dog.

Acceleration due to gravity is independent of the mass of objects. . . . Two falling inflated balls of different masses land at the same time.

Air resistance increases with an increase in the surface area of objects. . . . A crumpled ball of paper falls faster than a sheet of paper of the same mass.

New stars form from ?
allsm [11]
Stars form from an accumulation of gas and dust, which collapses due to gravity and starts to form stars. The process of star formation takes around a million years from the time the initial gas cloud starts to collapse until the star is created and shines like the sun
