It's difficult to measure that because it's hard to make sure it is only a uniform layer of gas in whatever you're measuring it in
Answer:
Given:
Input Power (
)= 1000 W
Mass (m) = 100 kg
Height (h) = 10 m
Time (t) = 16 s
To Find:
Efficiency of the motor
Explanation:
Efficiency of the motor = 62.5 %
The best thing to do in this case is to redo the experiment and re record the info, it has to be precise and accurate so you also have to check if your procedure is correct. If the results are both accurate and precise then you have to report your findings to the committee of that specific field. <span />
An Independent Group/ between-subjects design differs from a within-subjects design in that a between-subjects design. The correct option is B.
<h3>What is independent measure design?</h3>
Studying between subjects (or between groups): As various subjects are used to test each condition, each subject is only exposed to a single user interface. internal topic (or iterative measurement) The same topic evaluates every circumstance (that is, all user interfaces).
Each participant in a topic or intergroup design only encounters one condition, and the group differences between individuals under various conditions are compared. The in-subject design, in which every participant is exposed to every condition, is the antithesis of this.

Answer:
B) Amplitudes
Explanation:
The equations of the electric and magnetic fields given are sinusoidal functions. he sine function varies between the value of -1 and 1 when is multiplied by a number A then varies from -A to A. In this case the variation goes from -E0 to E for the electric field and from -B0 to B0 for the magnetic field. Because the amplitude is half of the distance between the highest and the lowest value of the sinusoidal function. In the electric field is: E0-(-E0)/2=E0 and in the magnetic field B0-(-B0)/2=B0.
