Is visible light a form of radiation? Explain.

Physics
1 answer:
natali 33 [55]3 years ago
6 0

Answer:

Yes,in fact visible 'light' is a form of radiation, which can be defined as an energy that travels in the form of electromagnetic waves. It can also be described as a flow of particle-like 'wave-packets', called photons, that travel constantly at the speed of light (about 300 000 kilometres per second).

Kinect energy is expressed using the unit
Lorico [155]
Joule
The standard unit for kinetic energy is the joule (J). The joule is the standard unit for energy in general. Other units for energy include the newton-meter (Nm) and the kilogram meter squared over seconds squared (kg m2/s2).

A cyclist racing in the keiran is riding at the top of the track at 5m/s. Then he sprints downhill in the sprinting to the finis
kumpel [21]
The cyclist is moving by uniformly accelerated motion, with an initial velocity of v_i=5~m/s and an acceleration of a=9~m/s^2. 
The acceleration is given by
a= \frac{v_f-v_i}{\Delta t}
where v_f is the final velocity and \Delta t is the time between the end and the beginning of the motion, and in our case it is 1.75 s. Therefore, from this relationship we can find the final velocity:
v_f=v_i + a \Delta t=5~m/s+9~m/s^2 \cdot 1.75~s=20.75~m/s

If a point charge is located at the center of a cylinder and the electric flux leaving one end of the cylinder is 20% of the tot
zheka24 [161]

The portion of the flux leaves the curved surface of the cylinder is 60%.

<h3 /><h3>What are electrons?</h3>

The electrons are the spinning objects around the nucleus of the atom of the element in an orbit.

If a point charge is located at the center of a cylinder and the electric flux leaving one end of the cylinder is 20% of the total flux leaving the cylinder.

If 20% of the flux leave from one end, then another 20% will leave from another end.

So, the net flux through curved surface is

100 -20 -20 = 60%

Thus, the total flux  leaves the curved surface of the cylinder is 60%

How many minutes does it take light from the sun to reach earth? (the distance from the sun to earth is 93 million mi; the speed
LenKa [72]

The speed of light is given which is 3*10˄8 = 300,000,000 m/s <span>
93,000 miles = 149,668,992 000 meters - distance from sun to earth 
149,668,992,000/300000000 = 498.9 seconds - time for light from sun to reach earth 
498.9 seconds/60 seconds per minute = 8.3 minutes - time for light from sun to reach earth </span>

<span>So the answer is approximately 8 minutes.</span>
