The weight of an object is a measure of the force exerted on the object by gravity, or the force needed to support it whereas mass is the amount of matter contained in a body. The SI unit of weight is Newton whereas the SI unit of mass is Kilogram.
No idea about weightless maybe the objects not apparently acted on by gravity.
Answer:
Sound wave can be described by five characteristics: Wavelength, Amplitude, Time-Period, Frequency and Velocity or Speed.
Female flies are the one that are saddle with the responsibility of laying eggs during reproduction. The female usually look for a warm and moist place that have abundance food source for laying the eggs. The eggs laid by by the flies transformed into larva, which is also called maggots and the maggots turn into flies.

<u>Answer:</u> The charge on each plates is 
.
<u>Explanation:</u>
The magnitude of charge that flows through the plates is directly dependent on the capacitance and the voltage flowing through the plates.
Mathematically,
where,
Q = charge flowing = ? C
C = capacitance = 
(Conversion Factor: 
)
V = Voltage across the plates = 12 V
Putting values in above equation, we get:
Hence, the charge on each plates is .
