Answer:
A series circuit has a direct flow of current and because of that, the current is constant throughout the circuit, while the voltage is what changes.. In a parallel circuit, the current travels through multiple paths, so the current is divided among those paths. The voltage, on the other hand, is constant.
Explanation:
Definition of series and parallel circuits.

The difference between a fuse and a circuit breaker is that a fuse is a one time circuit element while a circuit breaker is a multiple use device. If you were designing a circuit for a reading lamp, you should include a circuit breaker so you don't have to replace it every time.
The magnetic field of Earth is caused by currents of electricity that flow in the molten core. ... The currents flow in the outer core, and the lines of force shown in yellow, travel outwards through the rest of the earth's interior. If the earth rotated faster, it would have a stronger magnetic field.
Answer:
the value of vA that will allow the car to coast in neutral so as to just reach the top of the 150 m high hill at B with vB = 0 is 31.3 m/s
Explanation:
given information
car's mass, m = 1200 kg
= 100 m
=
= 150 m
= 0
according to conservative energy
the distance from point A to B, h = 150 m - 100 m = 50 m
the initial speed
final speed = 0
thus,
² = ² - 2 g h
0 = ² - 2 g h
² = 2 g h
= √2 g h
= √2 (9.8) (50)
= 31.3 m/s
We will first convert all units to meters and then solve the problem.
We are given that:
1000 mm = 1 m
120 mm = ?? meters
using cross multiplication:
120 mm = (120*1) / 1000 = 0.12 m
Now, when the two objects are placed over each other, their total height is the result of summation of both heights, therefore:
total height = 0.12 + 1.5 = 1.62 m
Based on the above calculations, the correct choice is:
<span>b) 1.62 m </span>
