A spectrophotometer would be useful in experiments involving determining the concentration of a solution by measuring its absorbance, studying the kinetics of enzyme reactions by monitoring changes in absorbance over time, and identifying unknown substances by comparing their absorbance spectra to known compounds.
What else can I help you with?
What method would best allow these three different scientists to demonstrate their concepts?
For a physicist, conducting controlled experiments and analyzing data would be the best method to demonstrate their concepts. For a biologist, conducting field studies and experiments on living organisms would be ideal. For a psychologist, conducting experiments, surveys, and observational studies to gather data on human behavior would be the method of choice.
What energy is useful and what energy is wasted in a bungee jumper?
Useful energy would be the potential energy stored in the bungee cord when it is stretched out at the top of the jump, which is converted to kinetic energy as the jumper falls. Energy that is wasted would include any sound, heat, and other forms of energy dissipated as the bungee cord stretches and returns to its original length.
What example evaporation is not useful to us?
Evaporation in a puddle in a deserted area where there is no immediate need for the water evaporating would be an example of evaporation that is not useful to us.
How did Albert Einsten conduct his experiment?
Some of Einstein's experiments were called thought experiments. So he thought about what would happen under unusual circumstances, like a train speeding up to a velocity near the speed of light.
What is the efficiency of a machine that miraculously converts all the input energy to useful output energy?
The efficiency of such a machine would be 100%, as all the input energy is converted to useful output energy without any losses. This would be an ideal scenario but is not practically achievable due to factors such as friction, heat dissipation, and other forms of energy loss in real-world machines.
When would an airplane be useful?
In WWII an airplane would be useful to bomb the other countries.
Why are experiments on human illegal?
If people used experiments on each other, there would be a lot more deaths on innocent people.
How would you measure a subatomic particle?
These measurements are the result of experiments or are derived from other physical data.
What properties are least useful in identifying a mineral?
Color and streak would be the least useful, because they may be shared by a multitude of other minerals.
Should programmers create programs that are useful to themselves and other people?
Why would they create programs if it won't even be useful for themselves...Ofcourse they should create programs that are useful to themselves and other people..that's why programming is invented for advantages....
Would the little albert research study be conducted today?
no because of the board of ethics in the US today does not allow for these kind of experiments to be performed. European countries on the other hand may allow for such experiments.
Is Toilet paper useful?
Exceedingly. Other than that you would just use leaves or your hands!!
Why would a graph be useful for an experiment?
yes....it would be very useful
What is true controlled experiments produce valid data valid experiments produce controlled data controlled data produces valid experiments?
With controlled experiments it is taken into consideration what possible variables there could be and it is taken into account when conducting the experiment. This would mean that controlled experiments would produce more valid data.
What would happen if laboratory workers did not sterilise their equipment?
Then constantly, experiments and tests would produce "un-accurate" answers, because of the other foreign microbes on their equipment.
Did Galileo do experiments with his children?
no it would be dangeras
What information would be most useful for classifying elements by how they bond with each other?
I consider that this information is the electronegativity.
