Due to the photon's energy, which is higher in blue light than green. When you point to the right, you can see that blue light can produce bigger amounts of energy than green light now does. The current of blue light is, therefore, greater than that of green light. Wit, Gore predicts that we will have most of the color violet and the least of the color red. Violet has more energy, and as we descend, energy declines since blue have more energy.

What is the photoelectric effect and how did it change our concept of light and matter?

Heinrich Rudolf Hertz, a German physicist, developed the photoelectric phenomenon in 1887. Hertz discovered that when ultraviolet light shines on two metal electrodes with a voltage put across them, the light alters the voltage at which sparking occurs. This discovery is related to his work on radio waves.

What colors of light would cause the photoelectric effect?

The photoelectric effect refers to the finding that, under some circumstances, light striking a metal surface can result in the ejection of electrons. The light in the animation gains energy as it transitions from red to orange to yellow to green to blue.

To convert centimeters to kilometers, which conversion factors would you need?
Lelechka [254]

Answer:

The last option is the only correct one if you like to multiply

The second last option is good if you like to divide.

Explanation:

Each fraction in the last two options has a value of 1

example

dividing by 1

15 cm /(100 cm/ 1 m) = 0.15 m          0.15 m / (1000 m/ 1km) = 0.00015 km

and

multiplying by 1

15 cm(1 m / 100cm) = 0.15 m         0.15m(1 km/1000m) = 0.00015 km

only one of the two fractions in each of the top two options has a value of 1.

A 3.5-kg object placed on an inclined plane (angle 30? above the horizontal) is connected by a string going over a pulley to a 1
Blababa [14]

Answer:

a= 0.22 m/s²

Explanation:

Given that

M = 3.5 kg

θ = 30°

m = 1 kg

μ= 0.3

The force due to gravity

F₁= M g sinθ

F₁=3.5 x 10 x sin 30

F₁= 17.5 N

F₂ = m g

F₂ = 1 x 10 = 10 N

The maximum value of the friction force on the incline plane

Fr = μ M g cosθ

Fr = 0.3 x 2.5 x 10 cos30°

Fr= 6.49 N

Lets take acceleration of the system is a  m/s²

F₁ - F₂  - Fr =  (M+m) a

17.5 - 10 - 6.49 = (3.5+1)a

a= 0.22 m/s²
