Its C as gamma "rays" are high frequency electromagnetic waves not particles
Answer:
17%
Explanation:
Given parameters:
Atomic mass of nickel isotope = 57.9g/mol
Experimental value of atomic mass = 59.6g/mol
Unknown:
Percentage error in the measurement.
Solution:
The percentage error shows how much uncertainty was introduced into a measurement. To calculate this, we simply use the expression below:
Percentage error =
Percentage error = x 100 = 17%
Answer:
Measuring a pencil in meters would be very difficult, as a single meter is much longer than one pencil. Also, measuring a hallway in millimeters would be very difficult considering how small millimeters are in comparison to a hallway. However, if you switch these two then they would work very well.
C. All of the missing mass has been converted into heat energy. It doesn’t affect the Law of Conservation of Mass because it uses Einstein’s law E=MC2
