Concept explainers
The terminals of a battery are connected across two resistors in parallel. The resistances of the resistors are not the same. Which of the following statements is correct? Choose all that are correct. (a) The resistor with the larger resistance carries more current than the other resistor. (b) The resistor with the larger resistance carries less current than the other resistor. (c) The potential difference across each resistor is the same. (d) The potential difference across the larger resistor is greater than the potential difference across the smaller resistor. (e) The potential difference is greater across the resistor closer to the battery.

- give a brief definition of the word "paradigm" as well as an example of a current scientific paradigmarrow_forward7. Are all scientific theories testable in the commonly understood sense? How does this make you feel? How should you proceed as a scientist or engineer with this understanding?arrow_forwardWhat is an an example of a hypothesis that sounds scientific but is notarrow_forward
- What is an example of a scientific hypothesisarrow_forwardMultiverse is called a theory. It has been proposed to account for the apparent and uncanny fine tuning of our own universe. The idea of the multiverse is that there are infinite, distinct universes out there - all with distinct laws of nature and natural constants - and we live in just one of them. Using the accepted definition of the universe being all that there is (matter, space and energy), would you say that multiverse is a scientific theory?arrow_forwardHow is a law usually different than a theoryarrow_forward
- A 1.50 mLmL syringe has an inner diameter of 5.00 mmmm, a needle inner diameter of 0.270 mmmm, and a plunger pad diameter (where you place your finger) of 1.2 cmcm. A nurse uses the syringe to inject medicine into a patient whose blood pressure is 140/100. Part A What is the minimum force the nurse needs to apply to the syringe? Express your answer with the appropriate units. View Available Hint(s)for Part A Hint 1for Part A. How to approach the question The force the nurse applies to the syringe can be determined from the fluid pressure and the area of the plunger. The minimum force corresponds to the patient's lowest blood pressure. Use the following equality 760mmofHg=1atm=1.013×10^5Pa760mmofHg=1atm=1.013×10^5Pa.arrow_forwardA 1.50 mLmL syringe has an inner diameter of 5.00 mmmm, a needle inner diameter of 0.270 mmmm, and a plunger pad diameter (where you place your finger) of 1.2 cmcm.

- what is the agenda of physicsarrow_forwardWatch the video of Cooper’s play, while conducting and documenting your observation using a chosen observation tool. Case Study 1b - Cooper Carol has asked you to support the babies and toddler’s room educators this week. She has requested that you complete an observation on Cooper, who is a 10-month-old toddler. Carol wants to see how well you conduct an observation and is interested in how you manage to communicate in any observations made, using a strengths-based, non-judgemental, anti-biased approach, as this is a fundamental part of creating a supportive and respectful culture at Little Catalysts ELC.
