Awatch with a second hand will always be considered more than a watch with just an hour hand.
a. inaccurate
c. significant
b. expensive
d. precise

d) Precise

Explanation:

As we know that accuracy of the reading depends on the factors like how the device is used while measuring the things.

Also it will depend on the error that initial present in the device

But let say if we used the device properly with all the correct measures then the error in the reading is not there.

Now the another parameter of the measurement is Preciseness

If the reading is taken upto large number of decimals then it is known as precise reading because we can find its value for large end of readings.

So here if a clock is having hours hand while another clock is also having seconds hand so it means the with second hand must be Precise clock as it will give us the time in seconds also

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.
