Billy did an investigation to learn whether bean plants will grow if they are given salt water. billy repeated his experiment three different times. each time, he used the same kind of been seeds, and he made the salt water by adding exactly 20 grams of salt to 1 liter of water. what is billy doing by using the same beans and making the salt water exactly the same way each time?
a. using consistency and precision
b. making hypotheses and inferences
c. using safety and observation
d. making predictions and conclusions

What is the internal energy of 4.00 mol of diatomic nitrogen gas n2 at 455k

You've already seen the value of 9.8 in this lesson. what's this value called? what quantity does it represent?

We will use a video to study faraday’s law of electromagnetic induction by analyzing the induction that occurs due a coil of copper wire sliding along an air track that passes through an external magnetic field. specifically, we will: examine some of the main principles behind faraday’s law. apply lenz’s law to determine the direction of the induced emf. take measurements of the induced emf from the voltmeter as the coil passes into and out of the external magnetic field. use the horizontal scale provided to determine the speed of the coil. calculate the magnetic field induced in the coil as it passes into and out of the external magnetic field.
