An electrician is creating a wiring plan for a small house. He needs to create a plan that will allow the homeowners to turn off

lights in one room without turning off the lights in another. What should he do to assure that each room's lights function independently of one another?
A) He should wire each room in series with the next.
B) He should wire each room in parallel with the next.
C) He should make sure each room's lights provide the same resistance.
D) He should wire the room with the most lights directly to the circuit breaker box.

So the answer is B) he should wire each room in parallel. This is because when the bulbs are in parallel if one part of the parallel circuit is broken (eg when you switch a light off) then the current can still flow to all the other bulbs, meaning they stay turned on. Hope this helps :)

A Carnot engine has an efficiency of 0.537, and the temperature of its cold reservoir is 379 K.
katen-ka-za [31]

Answer:

(A) Th = 818.6 K

(B) Qh = 14211.7 J

Explanation:

efficiency (n) = 0.537

temperature of cold reservoir (Tc) = 379 K

heat rejected (Qc) = 6580 J

(A) find the temperature of the hot reservoir (Th)

 n = 1 - \frac{Tc}{Th}

0.537 = 1 - \frac{379}{Th}

\frac{379}{Th} = 1 - 0.537 = 0.463        

Th = \frac{379}{0.463}

Th = 818.6 K

(B) what amount of heat is put into the engine (Qh) ?

from \frac{Tc}{Th} = \frac{Qc}{Qh}

Qh = 6580 ÷ \frac{379}{818.6}

Qh = 14211.7 J

A 97.6-kg baseball player slides into second base. The coefficient of kinetic friction between the player and the ground is μk =
Mila [183]

Answer:

v=6.65m/sec

Explanation:

From the Question we are told that:

Mass m=97.6

Coefficient of kinetic friction  \mu k=0.555

Generally the equation for Frictional force is mathematically given by

 F=\mu mg

 F=0.555*97.6*9.8

 F=531.388N

Generally the  Newton's equation for Acceleration due to Friction force is mathematically given by

 a_f=-\mu g

 a_f=-0.555 *9.81

 a_f=-54455m/sec^2

Therefore

 v=u-at

 v=0+5.45*1.22

 v=6.65m/sec

Vedmedyk [2.9K]

I don't know the choices but...

Answer:

Sedimentary rock is a rock formed underground, usually under a source of water too. The rock is made up of smaller rock that, over the years, fused together and solidified.
