Answer:
Current would decrease 9 times.
Explanation:
Assume all others (potential difference U, resistivity ρ, and length L) are the same, only change in the diameter, we would have the following ratio


So the current would decrease 9 times.
Answer:
To see objects smaller than microscopic limits
Explanation:
The theory of Relativistic Quantum mechanics can be applied to particles that are massive and propagates at all velocities even those which are comparable to the speed of light and is capable to accommodate particles that are mass less. This theory find its application in atomic physics, high energy physics, etc.
It is necessary to use relativistic quantum mechanics when it is desired to see the objects that are too small to be seen with the help of microscope.
KE=1/2 mv²
60,500,000 = 1/2 m ( 11,000 m/s )²
60,500,000= 1/2 ( 11,000 )² m
60,500,000= 60,500,000 x m
m= 60,500,000/60,500,000
m= 1 kg
Answer : a rock that contains a metal resource
Reason :
Ore - a naturally occurring solid material from which a metal or valuable mineral can be profitably extracted.
Answer:
Meteorologists use a variety of tools to help them gather information about weather and climate. Some more familiar ones are thermometers which measure air temperature, anemometers which gauge wind speeds, and barometers which provide information on air pressure.
