I believe it is A. Electrons reside in known positions in fixed orbits around the nucleus
Answer: The complexity of filter is the order of the filter. Greater the order of the filter, more efficient the filter is. Roll of value of one filter is 20dB/dec. So the roll-off value of 8th order filter is 160dB/dec. 8th order filter is more efficient than the second order low-pass filter.
Answer:Train A is 90 m long and running at 72 km/h.
Train B is 120 m long and running at 36 km/h.
When the trains are running in opposite directions, their relative speed gets added: 72+36 = 108 km/h.
The total length of A and B = 90+120 = 210 m
So the time taken to cross each other = 210 m*60*60/108*1000m
= 7 seconds
Explanation:
Answer:
Energy Bill fluctuations are inevitable and depend on a variety of different factors. Two of the most important are the current weather your home is experiencing and the current price per Kilowatt Hour (which fluctuates more than you might think).
By definition we have that the linear moment is
p = m * v
Where
m = mass
v = speed.
Clearing the mass we have
m = p / v
Substituting the values
m= (13,300 kgm/s)/(14 m/s)=950Kg
the mass of the car is 950 Kg
