For states with larger values of n that admit a d subshell, the d subshell is at even higher energy than the p subshell. in fact, its energy is higher than that of the s subshell for the n+1 state. with this in mind, which of the following are valid ground-state electron structures? 1. 1s2 2s2 2p63 s2 3p6 3d22. 1s2 2s2 2p6 3s2 3p6 3d113. 1s2 2s2 2p6 3s2 3p6 4s2 3d5a. 1b. 2c. 3d. 1 and 2e. 1 and 3f. 2 and 3

Assume similar data for the motion of the blood in your aorta. estimate how many beats of the heart it will take the blood to get from your heart to your brain. (assume that the distance from your heart to your brain is 30 cm)

The speed of sound in ice, water, and steam is shown. what best explains the speed of sound in different states of matter? sound travels fastest in ice because energy is easier to transfer when the molecules are close together. sound travels slowest in steam because the sound has to move around the gas molecules that are far apart. sound travels fastest in ice because the temperature of solids is always greater, so the heat transfers the sound energy. sound travels slowest in steam because the pressure is so great the sound cannot travel though the steam particles.

During a car accident, a 125kg driver is moving at 31m/s and in 1.5s is brought to rest by an inflating air bag. what is the magnitude of the change in momentum to the driver
