Which statement is true for the hang time of a projectile?

Physics
1 answer:
Neporo4naja [7]3 years ago
8 0
The hang time of a projectile can be calculated solely by knowing the vertical component of the velocity of projection.

This is because all projectiles with the same vertical component of velocity are in flight for the same time.This is possible only if we are able to find the vertical component of velocity and the flight time with the given information.

What is the kinetic energy of a 478 kg object that is moving with the speed of 15 m/s
Tpy6a [65]
Kinetic energy = (1/2)*mass*velocity^2
KE = (1/2)mv^2
KE = (1/2)(478)(15)^2
KE = 53775J

After a match has burned which of these is not proof that a chemical reaction occurred?
mixas84 [53]
In my estimation I would say C, I was leaning towards A, but I believe that would merely be "incomplete combustion." I hope this was semi-helpful!

What is the difference between amplitude and wavelength?
jasenka [17]

Answer:

Letter b is wavelength. Letter a is amplitude.

Explanation:

Let's imagine a simple experiment. Imagine you have a long thick rope which one end is at your hands, and you start an oscillatory motion in it, moving your hand up and down. Then a friend of you take a picture of the rope in motion, looking at the rope laterally. Now let's find the wavelength and amplitude. Amplitude is "The distance from the center of the oscillation of the rope (when the rope was not in motion) to its high or low point", or the vertical displacement, in our experiment. On the other hand, wavelength is "The distance between one high point /low point and the next high point /low point". Take a look at a photo of a wave in your textbook and you will find the answer as well. ; )
