I believe that L is in feet while t is in seconds. To
find for the hang time, all we have to do is to plug in the value of L in feet
in the equation.
4 inches is equivalent to 4/12 feet or 0.33 feet,
therefore the total L is:
L = 4.33 ft
Using the equation to find for t:
L = 4 t^2
4.33 = 4 t^2
<span>t = 1.04 s</span>
Answer:
Atoms are composed of electrons (charge -1), protons (charge +1), and neutrons (no charge). So in a neutral atom the correct answer is "D".
Answer:
Push and pull both are forces , but the difference is in their direction at which it is applied . If the force applied in the direction of motion of the particle then we call it as push . If that force applied in the direction OPPOSITE to the motion of particle then it is termed as pull

Answer:
James Webb has been designed to focus on the infrared part of the spectrum from 0.6 (red light) to 28 microns (infrared). This means it won't be able to see in ultraviolet light like Hubble, but will be able to focus on infrared bright objects like extremely distant galaxies.
