Travelling energy = kinetic energy = half m v squared.
33750=(1/2)m 30^2
33750=15x30m
3375=15x3m
m=75kg

F=dP/dt. So you want the momentum to change as slowly as possible in time to minimize the force. So as you catch the egg, let your hand move backward with it for awhile, slowly bringing it to a stop. If you hold your hand steady when you catch it the force due to the impact could break it.

What is the relationship between the wavelength of the peak (maximum) of the Gaussian curve and the temperature in degrees Kelvi

Tomtit [17]

Answer:

$\lambda_{max}=\frac{b}{T}$

Explanation:

Wien's displacement law states that the radiation of the black body curve for different temperatures will give peak values at different wavelengths and this wavelength is related inversely to the temperature.

Formally the law of Wien displacement states that the black body's spectral radiation per unit of wavelength, will give peaks at the wavelength of $\lambda_{max}$ which is given by the mathematical expression.
