Answer:
to be precise in the calculations
Explanation: for example your cell phone has a gps inside it, the gps is responsible for providing direction data like a compass, if the equipment is not calibrated, the gps will not find the correct direction.
Answer:
The most correct option is A
Explanation:
The correct option is A because <u>all objects emit thermal radiation when there temperature is higher than absolute zero</u> - this is based on the Stefan-Boltzmann law. Hence, when the rods in an oven heat up above absolute zero, they begin to start emitting radiation. It should noted at this point that objects do not "emit" conduction and thus all options that involved "emitting conduction" are subsequently wrong.
Answer:
90%
Explanation:
Data obtained from the question include:
Actual yield = 585g
Theoretical yield = 650g
%yield =?
%yield = Actual yield /Theoretical yield x100
% yield = 585/650 x 100
% yield = 90%
Answer:
Basic oxides are oxides that show basic properties in opposition to acidic oxides and that either react with water to form a base; or react with an acid to form a salt and water which are called neutralization reactions.
