When it comes to hair-cutting, electric tools have become a staple for most stylists. The fine finish work and detail that is required to achieve a desired hairstyle is often accomplished with the use of electric clippers or trimmers.
These tools provide a precise and clean cut that is difficult to achieve with traditional scissors. Additionally, electric tools can often cut through thicker and coarser hair with ease, making them a versatile option for a variety of hair types. That being said, it's important for stylists to have a variety of tools in their arsenal and to choose the appropriate tool based on the task at hand. While electric tools are certainly useful, they are not always necessary for every cut or style. It's ultimately up to the stylist to determine the best approach for achieving the desired look.

CAN I GET ANSWERS PLEASE, I TRY THE FORMULA AND MY TEACHER HAS A FAMILY EMERGENCY SO HE CANT RESPOND BACK SO PLEASE HELP ME
Explanation:
I won't answer each of these, but will give you an explaination of how to solve for each.
You'll need to use Ohm's Law and Kirchhoff's Voltage Law.
Remember Ohm's Law as \(V = IR\).
Kirchoff's Voltage Law says that the sum of voltages for a given circuit "loop" must equal zero. In the circuit shown, this means that the voltage provided by the battery (E_T) equals the voltage drop across each of the three resisters in the loop.
\(E_T = E_1 + E_2 + E_3\)
A couple of other helpful notes:
These three resistors are in series which means that the current flowing through them is equal.
So it is easy to see that... \(V = IR \rightarrow E_1 = 4*2 = 8 V\)
Solve for the voltage across E_2 and E_3. The sum of the three voltages equals the voltage of the battery (E_T).

How to reflect a triangle about the line y=x+4 ?
To reflect a triangle about the line y=x+4, follow these steps: find the line's perpendicular, intersect the line, and reflect the vertices.
Reflecting a triangle about a given line involves finding the perpendicular line to the given line and then determining the new positions of the triangle's vertices. In this case, the given line is y=x+4.
To find the perpendicular line, we need to determine its slope. Since the given line has a slope of 1, the perpendicular line will have a slope of -1 (the negative reciprocal).
Next, we find the point of intersection between the given line and the perpendicular line. To do this, we set the equations of the two lines equal to each other and solve for x and y. Let's call the coordinates of the intersection point (a, b).
Now, we can determine the new positions of the triangle's vertices. For each vertex of the original triangle, we calculate the distance between the vertex and the intersection point. Then, we move the same distance in the opposite direction to obtain the reflected position. This is done for all three vertices of the triangle.
Once we have the new positions of the vertices, we can connect them to form the reflected triangle. The resulting triangle will be a mirror image of the original triangle with respect to the line y=x+4.

b) Calculate the value of the vibration, v after a time of t1 second.
c) Calculate the time when the vibration reaches the first maximum and minimum value
d) Sketch one cycle of the vibration function and clearly show the points calculated earlier.
a) The maximum value of the vibrations is 60 mm, and the angular frequency is 0.45π radians/second.
b) Calculate the value of the vibration, v, after a time of t1 second.
c) Calculate the time when the vibration reaches the first maximum and minimum value.
d) Sketch one cycle of the vibration function and indicate the calculated points.
How can we determine the maximum value, angular frequency, value after a given time, and the time when the vibration reaches its first maximum and minimum?a) The maximum value of the vibrations is 60 mm, representing the amplitude of the sinusoidal function. The angular frequency, 0.45π radians/second, determines the rate at which the vibrations oscillate.
b) To calculate the value of the vibration, v, after a time of t1 seconds, substitute the value of t1 into the given equation.
c) The vibration function completes one full cycle when the argument inside the sine function, 0.45πt - θ, equals 2π. By setting this equation equal to 2π, we can solve for the time at which the vibration reaches its first maximum and minimum value.
d) Sketching one cycle of the vibration function involves plotting the displacement of the motor over time, starting from a point where the vibration is at its maximum. Indicate the calculated points, such as the maximum and minimum values and the time when they occur, on the graph to visually represent the behavior of the vibration.
By understanding the maximum value, angular frequency, value after a given time, and the time of first maximum and minimum, we gain insights into the characteristics and behavior of the mechanical vibrations in the factory.

A battery with an f.e.m. of 12 V and negligible internal resistance is connected to a resistor of 545 How much energy is dissipated by the resistor in 65 s?
Answer:
When are resistors in series? Resistors are in series whenever the flow of charge, called the current, must flow through devices sequentially. For example, if current flows through a person holding a screwdriver and into the Earth, then
R
1
in Figure 1(a) could be the resistance of the screwdriver’s shaft,
R
2
the resistance of its handle,
R
3
the person’s body resistance, and
R
4
the resistance of her shoes.
Figure 2 shows resistors in series connected to a voltage source. It seems reasonable that the total resistance is the sum of the individual resistances, considering that the current has to pass through each resistor in sequence. (This fact would be an advantage to a person wishing to avoid an electrical shock, who could reduce the current by wearing high-resistance rubber-soled shoes. It could be a disadvantage if one of the resistances were a faulty high-resistance cord to an appliance that would reduce the operating current.)
Two electrical circuits are compared. The first one has three resistors, R sub one, R sub two, and R sub three, connected in series with a voltage source V to form a closed circuit. The first circuit is equivalent to the second circuit, which has a single resistor R sub s connected to a voltage source V. Both circuits carry a current I, which starts from the positive end of the voltage source and moves in a clockwise direction around the circuit.
Figure 2. Three resistors connected in series to a battery (left) and the equivalent single or series resistance (right).
To verify that resistances in series do indeed add, let us consider the loss of electrical power, called a voltage drop, in each resistor in Figure 2.
According to Ohm’s law, the voltage drop,
V
, across a resistor when a current flows through it is calculated using the equation
V
=
I
R
, where
I
equals the current in amps (A) and
R
is the resistance in ohms
(
Ω
)
. Another way to think of this is that
V
is the voltage necessary to make a current
I
flow through a resistance
R
.
So the voltage drop across
R
1
is
V
1
=
I
R
1
, that across
R
2
is
V
2
=
I
R
2
, and that across
R
3
is
V

=
I
R

. The sum of these voltages equals the voltage output of the source; that is,
V

This equation is based on the conservation of energy and conservation of charge. Electrical potential energy can be described by the equation

Determine whether each relation is an equivalence relation. Justify your answer. If the relation is an equivalence relation, then describe the partition defined by the equivalence classes. (a) The domain is a group of people. Person x is related to person y under relation P if x and y have a common parent (i.e., x and y have the same biological mother or the same biological father or both). You can assume that there is at least one pair in the group, x and y, such that xPy. (b) The domain is a group of people. Person x is related to person y under relation M if x and y have the same biological mother. You can assume that there is at least one pair in the group, x and y such that xMy. (d) The domain is the set of all integers. xEy if x + y is even. An integer z is even if z = 2 k for some integer k.
1. The relation is not an equivalence relation.
2. The relation is an equivalence relation.
3. The relation is an equivalence relation.
How to determine if it is an equivalence relation1. If person x and person y share the same biological mother or father, then x and y also share the same biological mother or father.
If person x and person y share the same same mother or father and if person y shares the same biological mother or father as person z, then it is not necessarily the case that person x shares the same biological mother or father as person z.
2. If person x and person y share the same biological mother, then so does person y.
If person x and person y have the same biological mother and if person y and person z share the same biological mother, then person x must share the same biological mother as person z.
As a result, the relationship P is one of equivalence. All offspring of a single mother are regarded as belonging to the same class.
3. The relation E is an equivalence relation for the set of all even numbers and the set of all odd numbers. there are two equivalence classes as a result.

The steam generator provides a 10^6 kg/h of steam at 8 MPa, 480 degree C, of which 4 times 10^5 kg/ h is extracted between the first and second turbine stages at 1 MPa and diverted to a process heating load. Condensate returns from the process heating load at 0.95 MPa, 120 degree C and is mixed with liquid exiting the lower- pressure pump at 0.95 MPa. The entire flow is then pumped to the steam generator pressure. Saturated liquid at 8 kPa leaves the condenser. The turbine stages and the pumps operate with isentropic efficiencies of 86 and 80%, respectively. Determine a) the heating load, in kJ /h. b) the power developed by the turbine, in kW. c) the rate of heat transfer to the working fluid passing through the steam generator, in kJ /h. d) Sketch the processes on T- S diagram.
The analysis involved calculating the heating load, power developed by the turbine, rate of heat transfer to the working fluid, and sketching the processes on a T-S diagram.
To analyze the given system, we need to determine the heating load, power developed by the turbine, rate of heat transfer to the working fluid passing through the steam generator, and sketch the processes on a T-S diagram.
For the heating load, we calculate the heat transferred using mass flow rate and specific enthalpy difference.
To find the power developed by the turbine, we consider the isentropic efficiency of the turbine and use the same equation as for the heating load.
The rate of heat transfer to the working fluid passing through the steam generator is determined using mass flow rate and specific enthalpy difference.
Lastly, to sketch the processes on a T-S diagram, we plot the states of the working fluid at different points in the system and connect them with lines, labeling each process and state.

For the circuit shown in Figure below:
R1 = 10KOmega, R2= 1MOmega,
R3 = 10KOmega, R4 = 10KOmega, R5 = 150KOmega, R6 = 10KOmega. Find Av=Vo/Vi
Answer:
Av = -800
Explanation:
The gain to the output of the first op-amp is ...
A1 = -R2/R1 = -1000/10 = -100
The gain of the voltage divider R3/R4 is ...
A2 = R4/(R3+R4) = 10/(10+10) = 1/2
The gain of the second op-amp circuit from the positive terminal to the output is ...
A3 = 1+ R5/R6 = 1 + 150/10 = 16
Then the total circuit gain is ...
Av = A1×A2×A3 = (-100)(1/2)(16)
Av = -800

Additional comment
In the above, we have assumed ideal op-amps, with infinite gain and infinite input impedance. The resistor values used in the calculations are all Kohms, so we can avoid writing unnecessary zeros.
