Estimate the peak wavelength for radiation emitted from ice at -4.0 degrees celsius, assuming black body emission.

m

Explanation:

T = temperature of ice = - 4 °C

In kelvin, temperature is given as

T = -4 + 273 = 269 K

λ = Wavelength of radiation emitted

b = Wien's constant = 2.898 x 10⁻³ m K

peak wavelength is given as

inserting the values

m

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
