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.
Answer:

Explanation:
Given that,
If the mass of a body is 15 kg and produced an 4.2 m/s², we need to find the acceleration if the mass is 10 kg and the same force is applied.
Force is given by :
F = ma
Since force is same

So, if the mass is 10 kg, acceleration is 
B. all of nature follows uniform, unchaining laws.
Yes is the answer for you
Answer

Explanation:
given,
Side of square coil = 3.2 cm
Number of turns = 2720
magnetic field in the coil increases to = 0.45 T
time interval = 1.7 s
average induced voltage in the coil = ?
length = 0.032 m
