Answer:
The density of the material is defined as the mass of the material to its volume.
ρ = M / V
Explanation:
The density of the material is a scalar quantity.
If the mass and the volume of the material is known the density of the material can be calculated using the formula,
ρ = M / V
The mass of the material can be found using a physical balance.
The volume of a geometrically symmetrical material can be found using the geometrical measurement. For a brick,
V = l x b x h
For non-geometrically shaped material the volume can be found from the displacement method using water.
Answer:
The frequencies the other string could have are 258.4 Hz and 261.6 Hz.
Explanation:
Given;
beat frequency, Fb = 1.60 Hz
frequency of the first string, F₁ = 260.00 Hz
frequency of the second string, F₂ = ?
Beat frequency is given as;
Fb = F₂ - F₁ or Fb = F₁ - F₂
Fb + F₁ = F₂ or F₂ = F₁ - Fb
1.6 + 260 = F₂ or F₂ = 260 - 1.6
261.6 Hz = F₂ or F₂ = 258.4 Hz
Therefore, the frequencies the other string could have are 258.4 Hz and 261.6 Hz.
Answer:
The minimum feature size is 136.6 km.
Explanation:
It is given that,
Distance from planet Mars and Earth is, 
Diameter of the objective lens, d = 0.977 m
We need to find the minimum feature size, on the surface of Mars that your telescope can resolve for you. The expression for resolving distance is given by :
So, the minimum feature size is 136.6 km.

What is an agn outburst
?</h3>
An active galactic nucleus (AGN) is a compact area at the core of a galaxy with much higher-than-normal brightness throughout at least some section of the electromagnetic spectrum and features indicating that the luminosity is not created by stars. Excessive non-stellar emission has been reported in radio, microwave, infrared, optical, ultra-violet, X-ray, and gamma ray wavebands. The non-stellar radiation emitted by an AGN is thought to be the product of matter accretion by a supermassive black hole at the heart of its host galaxy.
Active galactic nuclei are the most brilliant and enduring sources of electromagnetic radiation in the cosmos, and as such, they may be utilised to find faraway objects.
