I dont get why its c i dont under the graph for the vertical component in option c

Answers

Answer 1

Answer: The vertical component grows at an increasing rate because
gravity is ACCELERATING the object vertically. So its speed
keeps growing. Speed is the slope of the displacement graph.

d. Tension gravity centripetal force and frictional force

One light beam has wavelength, λ1, and frequency, f1. Another light beam has wavelength, λ2, andfrequency, f2. Write a proportion that shows how the ratio of the wavelengths of these two light beams is
related to the ratio of their frequencies.

Answers

One light beam has wavelength, λ1, and frequency, f1. Another light beam has wavelength, λ2, and frequency, f2. Write a proportion that shows how the ratio of the wavelengths of these two light beams is related to the ratio of their frequencies as λ1/ λ2 = f1/ f2.

What is frequency?

The number of vibrations counted per second is called frequency. A wave is a group of vibrations that are referred to as energy. The bottom node is known as the crest, and the top node is known as the trough.

A proportion that shows how the ratio of the wavelengths of these two light beams is related to the ratio of their frequencies as λ1/ λ2 = f1/ f2.

The height of the Empire State Building is 318.00 meters. If a stone is dropped from the top of the building, what is the stone's velocity just before it strikes the ground?

Answers

This is a free-fall problem. This can be answered using one of the free-fall equations:

V^2 = 2gh or V = √(2gh)

Where V = velocity ; h = total height (given as 318m) ; g = acceleration due to gravity (as this is on Earth, let us use 9.8 m/s^2)

With the given values, we can substitute it into the equation directly like so:

V = √(2gh)
V = √(2 x 9.8 x 318)
V = √(6232.8)
V = 78.94808 or approximately 78.95 m/s

Therefore the stone's velocity just before hitting the ground is 78.95 m/s.

A horse has a kinetic energy of 29,400 j if the horse has a mass of 300 kg what is the horses speed?

Answers

If a horse has a kinetic energy of 29,400 Joules if the horse has a mass of 300 kilograms, then the speed of the horse would be 14 m / s.

What is mechanical energy?

Mechanical energy is the combination of all the energy in motion represented by total kinetic energy and the total stored energy in the system which is represented by total potential energy.

The expression for total mechanical energy is as follows

ME = PE + KE

As given in the problem a horse has a kinetic energy of 29,400 j if the horse has a mass of 300 kg,

The kinetic energy of the horse = 0.5 × 300 × v²

29400 = 150 × v²

v = 14 m / s

Thus , If a horse has a kinetic energy of 29,400 Joules if the horse has a mass of 300 kilograms, then the speed of the horse would be 14 m / s.

kinetic energy = 29.400 j
m= 300 kg

kinetic energy = ½• m• v²
kinetic energy = ½•300•v²
29400= 150•v²
29400 : 150 = V²
196 = V²

√196 = V

14 = V

What is the frequency of radiation emitted by a photon of light if the energy released during its transition to ground state is 3.611 × 10-15 joules? (Planck's constant is 6.626 × 10-34 joule seconds) 5.50 × 10-11 Hz 2.39 × 10-50 Hz 5.45 × 1018 Hz 1.633 × 1027 Hz

Answers

If i was feeling harsh today, I'd say the answer to your question is impossible to obtain due to the fact that photons do not emit radiation, photons ARE the radiation emitted. Though for the sake of it, here is the method...

The simple method:

E=hf

therefore f=e/h

f=(3.611x10^-15) / 6.63x10^-34)

Answer: 5.45x10^18
