What is the acceleration of a falling skydiver? Near the surface of the Earth, any object falling freely will have an acceleration of about 10 m/s 2. What happens to a skydivers acceleration? The skydiver accelerates towards the ground. As the skydiver gains speed, their weight stays the same but the air resistance increases. There […]
How do you know if a graph is direct or inverse?
How do you know if a graph is direct or inverse? Numerically: Direct Variation: Because k is positive, y increases as x increases. So as x increases by 1, y increases by 1.5. Inverse Variation: Because k is positive, y decreases as x increases. Is addition and subtraction inverse relationship? Addition and subtraction are inverse […]
What foods promote neurogenesis?
What foods promote neurogenesis? Intake of flavonoids, which are contained in dark chocolate or blueberries, will increase neurogenesis. Omega-3 fatty acids, present in fatty fish, like salmon, will increase the production of these new neurons. Conversely, a diet rich in high saturated fat will have a negative impact on neurogenesis. How does neurogenesis affect memory? […]

What temperature does it need to be to sunbathe?
What temperature does it need to be to sunbathe? 88° F: Perfect beach temperature. Hot enough that you have motivation to get in the water, not so hot that you bake too quickly. 90° F: Excellent sunbathing temperature. Is 25 degrees warm enough for the beach? Refreshing, but after a while it still feels too […]
What is the effect on the pressure of a gas if you simultaneously?
What is the effect on the pressure of a gas if you simultaneously? According to the combined gas law, When we halve the pressure and double the Kelvin temperature of a gas simultaneously, then the volume of the gas will be increased by a factor of 4. Chapter 8, Problem 65AP is solved. Does water […]
What causes changes in seasons?
Which of the following has the smallest atomic radius group of answer choices?
Which of the following has the smallest atomic radius group of answer choices? Helium What is the trend for atomic radius down a group? In general, atomic radius decreases across a period and increases down a group. Across a period, effective nuclear charge increases as electron shielding remains constant. Why does atomic radius increase as […]
What are the selection rules for vibrational transitions?
What are the selection rules for vibrational transitions? Thus, the selection rule for a harmonic oscillator transition is ∆v = ± 1. The physical meaning of the vibrational selection rule is this: The vibration must change the molecular dipole moment to have a non-zero (electric) transition dipole moment. Which transition between rotational energy levels is […]
