Communication circuit  <em>(D)</em> is becoming more common in residential electrical design and construction.  

LAN Ethernet cables, outlets, and even hubs and bridges, are being built into the walls of new homes, along with the usual electrical outlet wiring, to give the owner the networking infrastructure and internet access that everybody needs now ... without stringing a mess of cables on the floor and through doors all over the house.

andreev551 [17]

Answer:

C)

Explanation:

The buoyancy and weight of the wood have to be equal for the system to be in equilibrium. The total mass (then, weight) of the wood is the same, so the total buoyancy has to be the same. Since buoyancy is the weight of the liquid displaced, the volume of liquid displaced will be the same in either case, which means that the water level will remain unchanged.

In the illustration, the block on the table is at rest. Then, unbalanced forces act on the block. What is the result? Question 3
erastovalidia [21]

The block on the table will move towards the right when the given unbalanced force act on the object. Option C is correct.

<h2></h2><h2>Unbalanced Force:</h2>

When the force acting on the object is not equalized by the opposite force.

<h3>Net force: </h3>

It is defined as the vector sum of all forces acting on the object at an instance.

F = \vec F_1+\vec F_2+.....

Where,

F - net force

\vec F_1 - Force acting on the right = 10 N

\vec F_2 - Force acting towards left = -8 N

Put the values in the formula,

F = 10 +(-8)\\\\F = 2

Since the net force is positive it means the move towards the right.

Therefore, the block on the table will move towards the right when the given unbalanced force act on the object.
