The primary energy exhibited is:

friction: Heat energy

Due to friction. there is heat loss in mostly all machines.

nuclear power plant: Nuclear energy

In nuclear power plant, fission or fusion of radio-active substances produces large amount of nuclear energy.

toaster element: Heat energy

Heat energy is produced in the toaster when electricity passes through the element. This is used to heat the toasts.

welding torch: Heat energy

The heat energy produced in the welding torch is used in welding.

eraser sitting on a desk edge: Potential energy

Potential energy is possessed by a body due to virtue of its height.

light bulb: Heat energy and light energy.

The element inside the bulb gets heated first and then light energy is produced.

campfire: Heat energy

Heat is produced and then light energy in case of campfire.

moving car: Kinetic energy

A moving body has kinetic energy.

lump of coal in a storage bin: Potential energy

A lump of coal in a storage bin has potential energy.

stick of TNT: potential energy

Stick of TNT is formed of explosive mixture. It contains potential energy.

A discharge lamp rated at 25 W (1 W = 1 J/s) emits yellow light of wavelength 580 nm. How many photons of yellow light does the

Scrat [10]

Answer:

the number of photons of yellow light does the lamp generate in 1.0 s is 7 x $10^{19}$

Explanation:

given information:

power, P = 25 W

wavelength. λ - 580 nm = 5.80 x $10^{-7}$ m

time, t = 1 s

to calculate the number of photon(N), we use the following equation

N = λPt/hc

where

λ = wavelength (m)

P = power (W)

t = time interval (s)

h = Planck's constant (6.23 x $10^{-34}$ Js)

c = light's velocity (3 x $10^{8} m/s^{2}$ )

So,

N = λPt/hc

= (5.80 x $10^{-7}$ )(25)(1)/(6.23 x $10^{-34}$ )(3 x $10^{8} m/s^{2}$ )

= 7 x $10^{19}$
