Answer:
A complete circuit is a complete loop with electricity flowing the way it's supposed to flow: from the battery, to the component, and back to the battery again. An open circuit is an incomplete loop, where the loop is broken at a particular point and electricity can't flow at all
Explanation:
So, you can show one with how the electricity flows right through and then how the loop is broken so the electricity wont really flow.
Answer: A medium in which speed of light is more is known as optically rarer medium and a medium in which speed of light is less is said to be optically denser medium. For example in air and water, air is raer and water is a denser medium.
Explanation:
Answer:
Magnetic force, 
Explanation:
It is given that,
Magnetic field, B = 2 T
Velocity of the proton, v = 300 m/s
Charge on the proton, 
The magnetic field is oriented perpendicular to the proton’s velocity. The magnetic force on the charged particle is given by :
The magnetic field is oriented perpendicular to the proton’s velocity, 
So, the magnitude of the force that the proton experiences while it moves through the magnetic field is 
. Hence, this is the required solution.
Explanation:
Vi = 12 m/s
a = 3 m/s^2
t = 2 s
Vf = Vi + a × t = 12 + 3 ×2 = 18 m/s
