after catching the final out, an outfielder throws the baseball straight up in the air with an initial speed of 35 m/s. How long does it take to reach its highest point?


The wave function of the hydrogen atom in its ground state (1s) is ψ=(πa03)−12exp(−ra0 where a0=0.529×10−8 cm. The charge density is ρ(x,y,z)=−e|ψ|2, according to the statistical interpretation of the wave function.
Then the value of ⟨r⟩ is given by

a, 5a0^2

b, 2a0^2

c, 4a0^2

d, 3a0^2
The wave function of the hydrogen atom in its ground state (1s) is = (
1. A 2kg phonograph turntable with diameter 1.5m initially rotating at 4.5 rads makes 4 complete rotations before coming to a stop.

a) What is its angular acceleration

As a physicist, you are tasked to head the committee that will make a creative and interesting;

(a) a new system of units to describe something that interest you. Your unit should be described using at least two subunits. For example, you can decide to measure the quality of songs using a new unit called song awesomeness. Song awesomeness is measured and by: the number of songs downloaded and the number of times the song was used in movies. 

(b) create an equation that shows how to calculate your unit. Then using your equation, create a sample dataset that you could graph. Are your two subunits related linearly, quadratically, or inversely? Your output must be designed to apply scientific reasoning and critical thinking using physics principles.

A disoriented physics professor drives 3.25 km north, then 2.20 km west, and then 1.50 km south. Find the magnitude and direction of the resultant displacement using the component method.


Susan hikes 6 miles east, 15 miles north, 1 mile west and 3 miles south. What is her displacement?
