Ari uses a tool called calipers to measure the diameter of different cylinders he is using in an experiment. His old calipers co
Vladimir [108]

Answer:

Explanation:

Different measuring instruments have different level of precision . For example , our usual scale can measure upto 1 mm. Callipers can measure upto .1 mm. screw gauge can measure upto .01 mm.etc The deeper it can measure , the more precise it is. Hence screw gauge is most precise among the three.

On this basis we can say that , new caliper is less precise than old one.

Accuracy tells us about our result , how close our result is to the true measurement. It is dependent on  the manner in which  we take reading , So measuring methods , rather than measuring instruments , decide the accuracy of our result.

Hence we can say that the new caliper is less precise only.

A person in a wheelchair exerts a force of 25 newtons to go up a ramp that is 10 meters long. The weight of the person and wheel
Natali [406]

The work output of the procedure is given as,

W_O=wh

Substitute the known values,

\begin{gathered} W_O=(60\text{ N)(3 m)(}\frac{1\text{ J}}{1\text{ Nm}}) \\ =180\text{ J} \end{gathered}

Thus, the work output is 180 J.

The work input of the procedure is,

W_i=Fd

Substitute the known values,

\begin{gathered} W_i=(25\text{ N)(10 m)(}\frac{1\text{ J}}{1\text{ Nm}}) \\ =250\text{ J} \end{gathered}

Thus, the work input is 250 J.

The efficiency of the person is given as,

e=\frac{W_O}{W_i}

Substitute the known values,

\begin{gathered} e=\frac{180\text{ J}}{250\text{ J}} \\ =0.72 \end{gathered}

Thus, the efficiency of person is 0.72 or 72%.
