When developing an experimental design, the action that would improve the quality of the results is to ensure that it answers a question about cause and effect.
<h3>What is experimental design?</h3>
Experimental design is a concept used to organize, conduct, and interpret results of experiments in an efficient way, making sure that as much useful information as possible is obtained by performing a small number of trials.
Thus, when developing an experimental design, the action that would improve the quality of the results is to ensure that it answers a question about cause and effect.

For a diverging lens, the focal length is negative while it is positive for a converging lens
b) True
Image distances for virtual images are always negative and it also forms on the the same side of the lens as the object and is enlarged
c) True
d) False

Answer:
11.5
Explanation:
you do 12(sin 73.3) because its on the y you do sin
Classically and Newtonianly, it's the sum of the chemical energy if any,
the electrical energy if any, the thermal energy if any, and the mechanical
energy consisting of potential and kinetic energy if any.
The mechanical energy, consisting of potential and kinetic energy if any, is
0.001 x [ (acceleration of gravity x height) + (1/2) (speed)² ] .
But I've got a sneaky hunch that you're not talking about any of these.
You want to know how much [ <em><u>mc</u>² </em>] there is in 1 gram of mass. No prob.
E = m c² = (0.001) x (3 x 10⁸)² = <em>9 x 10¹³ joules</em>
That's the energy that a 1,000-watt toaster uses
in <em>2,852 years</em> of continuous toasting.
