The communication or data circuit is becoming increasingly popular in residential electrical design and construction, thanks to the rise of smart homes and home automation systems.
In the realm of residential electrical design and construction, the type of circuit becoming increasingly popular is the D. Communication circuit. This type of circuit, also known as a data circuit, is being more commonly used thanks to the surge in use of smart homes and home automation systems. These systems require a complex network of communication circuits to function, hence their amplified use in recent years.
Contrarily, A. Hazardous-area circuits, B. Three-phase circuits, and C. 480-volt circuits are not typically found in residential properties. They are usually used in commercial or industrial settings where the electrical demand is significantly higher.

Communication circuit (D) 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.
A.
Forces are defined by strength but not direction.
B.
Forces are defined by direction but not strength.
C.
Forces are defined by both strength and direction.
OD. Forces act only on objects that are in contact.
Answer:
C
Explanation:
Force is a vector quantity. So, it has magnitude and direction which can also be describe as strength and direction
Answer:
C.
Explanation:
Force has both direction and magnitude due to it being a vector quantity. Think of it this way--if I push you, what will happen to you?
Doesn't it depend on 1) how hard I pushed you, and 2) what direction I pushed you? Did I push you towards the wall? Towards a bed? How hard? Hard enough for you to fall?
What is the final speed of the car after this work is performed?
Answer:
9.4 m/s
Explanation:
The work-energy theorem states that the work done on an object is equal to the change in kinetic energy of the object.
So we can write:
where in this problem:
W = -36.733 J is the work performed on the car (negative because its direction is opposite to the motion of the car)
is the initial kinetic energy of the car
is the final kinetic energy
Solving for Kf,
The kinetic energy of the car can be also written as
where:
m = 661 kg is the mass of the car
v is its final speed
Solving, we find
Conduction
Electromagnetism
Convection
Answer:
CONDUCTION
Explanation:
When a driver touches a cars steering wheel on a hot day heat is transferred to the drivers hand by conduction
The heat is transferred to the driver's hand by conduction because his hand touched the steering wheel (i.e physical contact involved), the heat is transferred through the driver's hand as against radiation that doesn't require any physical contact.
I hope this helps.
a. Calculate the Force Friction
FN
The force of friction is 213.2 N
Explanation:
The frictional force acting on an object sliding on a surface is given by:
where:
is the coefficient of friction
m is the mass of the object
g is the acceleration of gravity
In this problem we have
m = 29 kg
Therefore, the force of friction is

As we know that mass of the box is given as
m = 9.5 kg
acceleration of the box is given as
so by Newton's II law we can say
now we can substitute all the values in it
So it required 9.5 N force to slide it
Answer:
True........................
Yes, it has a speed and a direction, and that makes a velocity. So it's True.
