A pulsar is a type of rotating neutron star that emits a beam of electromagnetic radiation. Imagine a pulsar that is moving toward Earth at a speed of 880.500 km/s. It emits mostly radio waves with a wavelength (at the source) of 123.500 cm.
What is the observed wavelength of this radiation on Earth? (Assume the Earth is stationary. Consider the speed of light c = 3.00000 x 10^8 m/s. Give your answer to at least six significant figures.)

The observed wavelength of this radiation on Earth is 123.1 cm.

Explanation:

Given that,

A pulsar is a type of rotating neutron star that emits a beam of electromagnetic radiation.

A pulsar that is moving toward Earth at a speed of 880.500 km/s,

It emits mostly radio waves with a wavelength (at the source) of 123.500 cm,

We need to find the observed wavelength of this radiation on Earth. The observed wavelength is given by :

So, the observed wavelength of this radiation on Earth is 123.1 cm.

this could be newton#'s law of cooling. the cooling curve is exponential

find the surface area of the sphere to the nearest square unit. use a calculator.
