Which two ways can light be understood

1 answer:

3 0

Around 1700, when Mechanics was made for the first time by Sir Isaac Newton, he said about the nature of the light that it resembles thiny particles. Somewhat latter , around 1865, Maxwell discovered that the Electromagnetic waves have the same speed as the speed of light. From this resemblance he deduced that light should be an Electromagnetic wave. Latter than this, at around 1900, when trying to explain some peculiarities of the Photoelectric effect, Eistein postulated that light behaves like thiny particles (the older Newton Theory from 1700).
Today we say that LIGHT HAS A DUAL CHARACTER. It is also a wave and a particle. In some experiments light behaves like an Electromagnetic wave (diffraction, reflection, refraction), in other experiments light behaves like thiny particles (quanta): the Photoelectric effect and the Compton effect.

N capacitors are connected in parallel to form a "capacitor circuit". The capacitance of first capacitor is C, second one is C/2

liberstina [14]

Answer:

Explanation:

The equivalent capacitance of a parallel combination of capacitors is the sum of their capacitance.

So, if the capacitance of each capacitor is half the previous one, we have a geometric series with first term = C and rate = 0.5.

Using the formula for the sum of the infinite terms of a geometric series, we have:

Sum = First term / (1 - rate)

Sum = C / (1 - 0.5)

Sum = C / 0.5 = 2C

So the equivalent capacitance of this parallel connection is 2C.

Wilma can mow a lawn in 80 minutes. Rocky can mow the same lawn in 120 minutes. Construct an equation that would allow you to de

xeze [42]

Answer:

$t = 96 minutes$

Explanation:

Time to mow 1 lawn by Wilma is 80 minutes

so work done in 1 minute by Wilma is given as

$W_1 = \frac{1}{80}$

Similarly Rocky mow same lawn in 120 minute

so work done in 1 minute by Rocky is given as

$W_2 = \frac{1}{120}$

now we know that they both worked by "t" time

so total work performed by them

$W = \frac{t}{80} + \frac{t}{120}$

they both mow 2 lawns then it is given as

$2 = (\frac{1}{80} + \frac{1}{120})t$

$t = 96 minutes$

Answer

Gravity is what holds us down on the earth's (or moon's) surface. If you were to weigh yourself on a scale on Earth and then on the moon, the weight read on the moon would be 1/6 your earth weight
