Answer:
1. the difference between a series circuit and parallel are if a bulb goes out in a series circuit all go out and in a parallel if one goes out all the others stay on.
2. the function of a switch is to determine if the circuit is closed or open and how is stays on.
Explanation:
Answer:
v = √(25/m)
Explanation:
KE = ½mv²
v = √(2KE/m)
We know the kinetic energy, but not the mass
v = √(25/m)
Answer:
1) The angle of deflection will be less than 45° ( C )
2) The angle of deflection will be greater than 45° but less than 90° ( E )
Explanation:
1) Assuming that the force applied has a direction which is perpendicular to the Earth's magnetic field
∴ Fearth > Fapplied hence the angle of deflection will be < 45°
2) when the Fearth < Fapplied
the angle of deflection will be : > 45° but < 90°
