Weight = mg where m = mass and g = gravity = 10 (9.81....)
so m = w/g = 4.9 / 10(9.81....) = 0.49 (0.49949....)
if you get given g as 10, answer is 0.49 kg 
if you get given g as 9.81, answer is 0.50 (1sf)

Answer:

The grapefruit's mass is 0.5 kg.

Explanation:

Given that,

Weight = 4.9 N

We need to calculate the mass

Using formula of newton's second law

F = mg

m = \dfrac{F}{g}

Where, F = weight on earth

g = acceleration due to gravity

Put the value into the formula

m = \dfrac{4.9}{9.8}

m =0.5\ kg

Hence, The grapefruit's mass is 0.5 kg.

The early workers in spectroscopy (Fraunhofer with the solar spectrum, Bunsen and Kirchhoff with laboratory spectra) discovered
Anestetic [448]

The hot gases produce their own characteristic pattern of spectral lines, which remain fixed as the temperature increases moderately.

<h3><u>Explanation: </u></h3>

A continuous light spectrum emitted by excited atoms of a hot gas with dark spaces in between due to scattered light of specific wavelengths is termed as an atomic spectrum. A hot gas has excited electrons and produces an emission spectrum; the scattered light forming dark bands are called spectral lines.

Fraunhofer closely observed sunlight by expanding the spectrum and a huge number of dark spectral lines were seen.  "Robert Bunsen and Gustav Kirchhoff" discovered that when certain chemicals were burnt using a Bunsen burner, atomic spectra with spectral lines were seen. Atomic spectral pattern is thus a unique characteristic of any gas and can be used to independently identify presence of elements.

The spectrum change does not depend greatly on increasing temperatures and hence no significant change is observed in the emitted spectrum with moderate increase in temperature.
