Using the solubility curve, choose all of the statements that are correct. The solubility of NaCl is least affected by temperature you can completely dissolve 60 g of KBr in 100 g of water at 20 °C the solubility of KNO3 is the least affected by changes in temperature 100 g of KBr will dissolve completely in 100 g of water at 75 °C if you mix 120 g of NaClO3 in 100 g of water at 10 °C, approximately 30 g will not dissolve

The two stars in a certain binary star system move in circular orbits. the first star, alpha, has an orbital speed of 36 km/s. the second star, beta, has an orbital speed of 12 km/s. the orbital period is 137 d. a) what is the mass of the star alpha? b) what is the mass of the star beta?

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.
