Answer:
Generally errors are classified into three types: systematic errors, random errors and blunders. Gross errors are caused by mistake in using instruments or meters, calculating measurement and recording data results.Measurement Error (also called Observational Error) is the difference between a measured quantity and its true value. It includes random error (naturally occurring errors that are to be expected with any experiment) and systematic error (caused by a mis-calibrated instrument that affects all measurements).
Answer: 1.62 m
Explanation: In order to solve this problem we have to use the definition of Coulomb force whic is given by:
F=(k*q1*q2)/d^2 where k is a constant 9*10^9 N/C^2*m^2. d is the distance between tha charges q1 and q2.
then we can:
d^2= (k*q1*q2)/F= (9*10^9*30.3*10^-6*68.2*10^-6)/7.09=1.62 m
(note we have considered q2 as positive because we are determining d^2 by using the magnitude of the electric Force bewteen the charges).
Answer:
I think the answer is a no. I guess
Explanation:
don't mind if it is write or wrong
1. true is the answer
2. The correct option is this: FIGURE II AND FIGURE IV ARE BOTH COMPOUNDS.Figure two and figure four have components that are of different colors, this means that different atoms had combined together to form a compound.3. dont know yet
4. The figure is a molecule and an element is the correct answer
5. Elements
6. Co2
7. Both are made of two or more atoms.
8. the answer is atom
Compared with an Earth year, a galactic year represents time on a grand scale but its not a consistent measurement across the galaxy
