Anit [1.1K]

Answer:

The 2 light bulbs can be connected in parallel to each other to avoid disconnection when one bulb burns out.

Explanation:

The parallel connection is required not series. A parallel connection is the connection of electronic components (e.g bulbs, LED, resistors, capacitors etc) in such a way that the same voltage is supplied across the ends of the components.  While in a series connection, the components are connected to each other end-to-end.

As regard the question, parallel connection ensures that the brightness any of the bulbs is not affected with respect to the other bulbs. And other bulbs continue to function when any burns out. The 2 light bulbs should be connected in parallel to the baterry to avoid disconnection of all the bulbs.

alukav5142 [94]

Since the two trains are passing in opposite directions, so this means that their relative velocities will be the sum of the two trains that is: 

<span>
relative velocity = (13 + 28) = 41m/s</span>

<span>
a. The passengers aboard on train B will see that train A is moving at 41m/sec due east</span>
