Heya!!

For calculate final velocity, lets applicate formula

                                                \boxed{V=V_o+a*t}

                                                 <u>Δ   Being   Δ</u>

                                            V = Final Velocity = ?

                                         Vo = Initial velocity = 4,3 m/s

                                          a = Aceleration = 3 m/s²

                                                 t = Time =5 s

⇒ Let's replace according the formula:

\boxed{V=4,3\ m/s +3\ m/s* 5\ s}

⇒ Resolving

\boxed{V=19,3\ m/s}

Result:

The velocity after 5 sec is <u>19,3 meters per second (m/s)</u>

For calculate distance, lets applicate formula

                                              \boxed{x=V_o*t+\dfrac{a*t^{2}}{2}}}

                                                 <u>Δ   Being   Δ</u>

                                               x = Distance = ?

                                         Vo = Initial velocity = 4,3 m/s

                                          a = Aceleration = 3 m/s²

                                                 t = Time =5 s

⇒ Let's replace according the formula:

\boxed{x=4,3 * 5 +\dfrac{3*5^{2}}{2}}}

⇒ Resolving

\boxed{x = 59 \ m}

Result:

The distance is <u>59 meters.</u>

Good Luck!!

Two sets of Christmas lights are available. For set A, when one bulb is removed, the remaining bulbs remain illuminated. For set
Paul [167]

Explanation:

Bulbs are nothing but resistors that glow when current passes through them.

In Set A, the bulbs (resistors) are connected  parallely to each other, this means that even if one of the bulbs fuses or removed, the circuit will still be completed and others continue to glow.

And in parallel connection if the resistance of the two resistors are same  powered delivered to each is same.

In Set B, bulbs are in series connection, this means that when one of the bulb is removed or fuses, the circuit will break and other bulbs can not operate.In this situation as well  if the resistance of two resistors is same then the power delivered is same.
