Hmm, I got that the wavelength is 500 meters.
Answer:
neutrinos and seismic vibrations
Explanation:
Answer:
The correct answer is option B.
Explanation:

f = focal length
P = -5.5 D (negative power means that lens is concave)

1 m = 100 cm
f = -0.1818 m = -0.1818 × 100 cm= -18.18 cm



v = -18.18 cm
v = 1.8 cm - far point
far point = 1.8 cm - v =1.8 cm - (-18.18 cm) = 19.98 cm
But closest answer from the given options is option B.Hence, 20 cm is the correct answer.
Answer:
False, When an object rolls over a surface, the kind of friction that occurs is called <em><u>ROLLING FRICTION</u></em>
Explanation:
Spectroscopy is the study of the absorption and emission of light and other radiation by matter.
<h3>How can we conclude the statement?</h3>
Spectroscopy is the interaction of lights and atoms and the study of the emission and absorption of light.
Spectroscopy can be defined as the study of light absorption as well as its emission. It is also uses to study of structure of atoms.
It offers techniques that has to do with how a sample responds to the radiation of light.
Its applications are:
- Used to determine atomic structure To determine metabolic functions
- studies spectral emissions
- Helps to improve the effectiveness of drugs
