Answer:
Group and Periods of the Periodic Table of Elements. The three major groups on the Periodic Table are the metals, nonmetals and metalloids. Elements within each group have similar physical and chemical properties.
The correct answer would be 1.35m/s sw.
Higher resolution cannot be achieved with a light microscope because wavelength of light is larger that wavelength of electrons.
<h3>What is light microscope?</h3>
Light microscope is defined as the type of microscope that makes use of visible light to magnify objects into images that can be observed.
The wavelength of light is larger than that of the electrons, therefore, higher resolution cannot be achieved with a light microscope.

Answer:
The magnetic field is
Explanation:
From the question we are told that
The mass of the metal rod is 
The current on the rod is 
The distance of separation(equivalent to length of the rod ) is 
The coefficient of kinetic friction is 
The kinetic frictional force is 
The constant speed is 
Generally the magnetic force on the rod is mathematically represented as

For the rod to move with a constant velocity the magnetic force must be equal to the kinetic frictional force so

=> 
=> 
=> 
Answer:
measurement of force amplification
