Explanation:
Below is an attachment containing the solution.
Answer:
<em>the acceleration is 9.8</em>
Explanation: <em>F = mA, 19.6 =2A, A = 9.8 m/s^2</em>
A positive charged atom has lost electrons.
Electrons are present in the outer shell of an atom, loosely bond to the nucleus, the only binding force on the electrons is the electric force, while the protons are inside the nucleus, and tightly bond to the nucleus by nucleus binding force, therefore an atom can only be positively charged when it loose electron from the shall.
Error is the difference between the true value of the measurand and the measured value.. Uncertainty characterizes the range of values within which the true value is asserted to lie with some level of confidence.
If that doesn’t help here’s the definition of both the terms,
Error:
A mistake
Uncertainty:
the state of being uncertain.
