Answer:
Unlike hard disks, which use magnetic charges to represent 1s and 0s, Compact Disks, DVD's or Blue Rays use reflected light.
Explanation:
The way CD's work is that they are hit by a laser beam which is reflected on the surface of the disc. These disks have some valleys and mountains that reflect light differently so the CD player will interpret these differences in reflection as data which will then be turned into music, videos or computer files.
Answer:
charge, q = ± 1.1 mC
Given:
Capacitance, 
Voltage, V = 110 V
Solution:
The charge on the capacitor plates can be calculated by using the definition of capacitance as :
q ∝ V
where
q = charge
V = potential difference or Voltage
Therefore,
q = CV
Now, charge, q :
q = 
Therefore, the charge on the positive plate is:
q = + 1.1 mC
the charge on the negative plate is:
q = - 1.1 mC
Answer:
-7.03645640575 Nm²/C
2.34548546858 Nm²/C
Explanation:
S = Surface area
Electric flux through the base is given by
The electric flux through the base is -7.03645640575 Nm²/C
Inside the tetrahedron there is no charge so total flux will be zero
The electric flux through the sides is 2.34548546858 Nm²/C
Answer: (1) Putrefaction
(2) Biodegradable
(3) Refuse.
Putrefaction refers to <u>decomposition of organic substances</u> usually dead plants' and animals' bodies <u>by microorganisms</u>.
Therefore, it matches with first definition that states the decay of organic matter caused by microorganisms.
Biodegradable substances are <u>decomposed by living organisms such as microorganisms.</u>
Therefore, it matches with the second definition that states susceptible to decomposition by living organisms.
Refuse refers to something which is <u>no longer useful</u>.
Therefore, it matches with the third definition of waste.
