Answer:
A) Electrons only
Explanation:
In quantum mechanics, "electron cloud" refers to the region of space where electrons can be found in an atom. In fact, in quantum mechanics, it is not possible to predict the exact position of the electrons, so there is a region where electrons have a certain probability to be found.
True
1 newton of force is the force required to accelerate an object with a mass of 1 kilogram 1 meter per second each second.
Answer:
b. 1600 watts
Explanation:
Modulation is the process of impressing a low frequency signal unto a high frequency signal so a to transmit over long distance.
If the modulation index (m) for an AM wave is less than 1, modulation would occur with no distortion, if m = 1, modulation occurs but if m > 1, it leads to over modulation and loss in AM envelope.
The total output power of an AM is the sum of the carrier power, upper side band power and lower side band power.
Total output power of an AM 
Pc is the carrier power. Given that modulation (m) = 50% = 0.5:

Answer:
7976 Pascals significant figure= 7.9*10^3
Explanation:
formula of hpg = height*density*gravitational energy
.80*10*997=7976 pascals
