Answer:
They have homologous structures because they have a common ancestor.
Explanation:
<h2>Answer: The Medium </h2><h2 />
<u>The medium is the main factor that differentiates a mechanical wave from an electromagnetic wave,</u> since the first can not propagate without its existence, while the second can propagate regardless of whether the medium exists or not.
In addition, it is the medium that will define, the propagation speed of the wave, according to its specific physical characteristics.
Answer:
the answer is c
Explanation:
melting = become liquefied by heat
solubility = a new bond formation
conductivity = electric transmitter
flammability = burnable
Answer:
0.4
Explanation:
A concave lens is a diverging lens, so it will always have a negative focal length. Image distance is always negative for a concave lens because it forms virtual images.
From the lens formula;
1/f = 1/u+ 1/v
- 1/2 = 1/3 - 1/v
1/v = 1/3 + 1/2
v= 6/5
v= 1.2 cm
Magnification = image distance/object distance
Magnification = 1.2cm/3cm
Magnification = 0.4
Answer:
0.8084g/cm³
Explanation:
For calculating density, mass is divided by volume.
Its units is commonly in grams per cubic centimeters.
Therefore,
density= mass/volume
= 404.2/500
=0.8084g/cm³
