Which of the following would be the best hypothesis for this experiment? a) use of the ginko biloba extract improves clinical outcomes when administered to patients with t2d. b) ginko biloba improves clinical outcomes of diabetes patients when combined with metformin. c) diabetes in patients is worsened when ginko biloba is taken in conjunction with metformin. d)the use of ginko biloba to treat t2d in combination with metformin lowers the cost of t2d treatment. ginko biloba shows benefits against t2d when combined with plant extracts as compared to other treatments.
A photoelectric cell is an electronic device which is used to convert light energy into electric energy.The operation of this device is based on photoelectric effect.
Light of suitable frequency i.e greater or equal to threshold frequency will fall on the cathode maintained at negative potential.The electron emission will take place and these electrons are drifted towards the anode which is at positive potential.
Here,only those radiations will be capable of emitting electrons irrespective of surface barrier of metals whose energy is greater than the work function.
We know that the radiation having long wavelength has least energy as energy and wavelength are inversely proportional to each other.
Here h is the Planck's constant,c is the velocity of light.
Here we have been given red light and blue light.
In the visible spectrum of radiation, the red light has longer wavelength than all other colors of light.Hence blue light has more energy as it's wavelength is less as compared to red light.
Hence, the blue light will activate the most and red the least.
answer would be A becuz that's the only reasonable choice according to real life situations
It will be the third one.
The Answer is A. If the amount of sugar in a drink increases, then the number of bees it attracts will increase. It doesn't measure the temperature, and all hypothesis use (IF) and (THEN) in the sentence so it can't be the 2nd choice
"If photoelectric cells respond better to short wavelengths of light,the red light should activate it the least and blue the most."
Stated above in the question.
" if the shells are affected by the level of acidity, then they will be weaker."
That hypothesis refers directly to the theory being questions in the problem.
