When a large rock is weathered into tiny pieces which add up the weight of the original rock, this demonstrates the law of conservation of matter.
According to this law the mass of an object doesn't change with time and also it does not depends on how the particles are arranged themselves.
Hence, option (C) is correct.
wavelength = speed/frequency
==> freq. = speed/wavelength = 342.5/0.75 = 456.67 Hz.
Since the circuit is incomplete or not closed, no current flows in the circuit. as per ohm's law , Voltage is directly proportional to current and is given as
V = Voltage = i R where i = current , R = resistance
as no current flows in the circuit, i = 0
the resistance R can not be zero. hence
V = 0 (R)
V = 0 Volts
so the magnitude of the Voltage is zero Volts
A type O star is likely to appear blue.
