As a consultant to a theme park, your job is to ensure the safety of the children's rides. You are able to calculate the net force of the roller coasters acting on a 16 kg child over time given a few select data points. At t = 18.48s the position was < 4.53, 2.25, -11.82 > m.
At t = 18.53s the position was <3.5100000000000002, 3.2600000000000002, -11.950000000000001 > m.
At t = 18.580000000000002s the position was <3.99, 3.95, -10.33 > m.

In the first time interval, from 18.48 to 18.53s, what was the average momentum?

These models show the electron structures of two different nonmetal elements. which element is likely more reactive, and why? element 1 is more reactive because it has fewer electron shells and is toward the top of its group on the periodic table. element 1 is more reactive because it has more electrons in its valence shell and is farther to the right on the periodic table. element 2 is more reactive because it does not have a valence shell close to the nucleus, so it will attract electrons. element 2 is more reactive because it does not have a full valence shell, so it will attract electrons.

What is the single most important equation in all of physics?

Awave has a wavelength of 7 mm and a frequency of 19 hertz. what is its speed?
