The length by which the guy wire stretches is; δ = 0.091 in
We are given;
Length of guy wire AB = 6ft = 72 in
Diameter of wire = 0.2 in
UDL = 200 lb/ft
From the free body diagram of the rigid beam system and the guy wire attached, we can say that;
Taking moments about point C gives;
∑Mc = 0; -(2000 * 5) + (F_BA * cos 30 * 10) = 0
-10000 + 8.66F_BA = 0
8.66F_BA = 10000
F_BA = 10000/8.66
F_BA = 1154.73 lb
Now, the length which it stretches is gotten from the formula;
δ = PL/AE
Where;
δ is change in length
P is Force
L is length of wire
A is area
E is modulus of elasticity of wire(steel) = 29000 ksi = 29000000 psi
A = πd²/4
A = π * 0.2²/4
A = 0.0314 in²
Thus;
δ = (1154.73 * 72)/(0.0314 * 29000000)

Draw a diagram to show what happens to plane waves when they strike a flat reflector placed at 45° to their direction of travel.
Since the angle of incidence is 45° using the law of reflection we can conclude the reflective ray will also make an angle equal to the angle of incidence i.e. 45° with the normal.
What are the three laws of reflection?1)The angle between the incident ray and the normal is equal to the angle between the reflected ray and the normal.
2)The incident ray, the normal and the reflected ray are all in the same plane.
3) Incident ray and refracted ray are on different sides of the normal.
Given:
Light rays strike at an angle of 45° to the plane.
Using the law of reflection we can easily draw the reflective wave.
Important terms:
Angle of incidence - it is the angle at which the light way strikes the plane mirror.
Angle of reflection- it is the angle at which the light way is reflected back by the plane mirror.
Now since the angle of incidence is 45° using the law of reflection we can conclude the reflective ray will also make 45° with the normal.

An object undergoes simple harmonic motion with time period of 2s and amplitude 0.5m. At time t=0 the displacement of the object is a maximum. What is the displacement of the object from the equilibrium position at time t=1.5s. Give your answer in meters, to one significant figure and without a unit
The correct answer is The object must be at equilibrium position. So, the displacement is obtained zero.
Given,
The simple harmonic motion has a time period of T = 2s
The amplitude of oscillation is A = 0.5 m
The displacement of the object from the equilibrium position at time t= 1.5 s should be determined.
At time t = 0 , the displacement of the object is maximum. For objects in SHM, the maximum displacement is equal to its amplitude.
The general equation of a particle in simple harmonic motion can be written as x = A sin(ωt + Φ) where A is the amplitude ω = 2π/T is the angular frequency and Φ is its initial phase which can be determined considering time t= 0 as follows,
x = A sin(ωt + Φ)
A = A sin ( ω × 0 + Φ )
sin Φ = 1
Φ = π/2
Therefore, the equation of the object in SHM becomes,
x = A sin(ωt + π/2)
x = A cos ωt ______(1)
Substituting, t = 1.5s the displacement can be obtained as,
x = 0.5 cos (2π/T × 1.5)
x = 0.5 cos (2π/2 × 1.5)

An ideal gas is in a sealed container. By what factor does the gas temperature change if the volume is halved and the pressure is tripled?.
The gas temperature change if the volume is halved and the pressure is tripled by factor 6.
What is an ideal gas?An ideal gas is theoretical gas composed of many randomly moving point particles that are not subject to interparticle interactions. The ideal gas concept is useful because it obeys ideal gas law, a simplified equation of state, and is amenable to analysis under statistical mechanics.
Considering combined law equation:
Temperature increases by factor of 6.
Gay-Lussac's Law
Gay-Lussac's Law indicates that, as long as volume of the container containing the gas is constant, as the temperature increases, the gas molecules move faster. Then number of shocks against the walls increases, that is, the pressure increases. That is, gas pressure is directly proportional to its temperature.
In summary, when there is constant volume, as the temperature increases, the gas pressure increases. And when temperature decreases, gas pressure decreases.
Gay-Lussac's law can be expressed as mathematically as follows:
where:
P= pressure
T= temperature
k= Constant
Boyle's Law
Pressure and volume are related by Boyle's law, which says that volume occupied by a given mass of gas at constant temperature is inversely proportional to pressure.
Boyle's law is expressed mathematically as follows:
P× V=k
where:
P= pressure
V= volume
k= Constant
Charles's Law
Finally, Charles's Law consists of the relationship that exists between the volume and the temperature of certain amount of ideal gas, which is maintained at a constant pressure.
This law says that for given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases. That is, volume is directly proportional to the temperature of the gas.
In summary, Charles' law is a law that says that when amount of gas and pressure are kept constant, the ratio between volume and temperature will always have the same value:
where:
V= volume
T= temperature
k= Constant
Combined law equation
Combined law equation is combination of three gas laws called Boyle's, Charlie's and Gay-Lussac's law:
Studying the two different states, an initial state 1 and an final state 2, the following will be true:
In this case, you know that:
Volume is double: V2= 2×V1
Pressure is tripled: P2= 3×P1
So, replacing in combined law equation:
Solving:
T2= 6×T1
Finally, temperature increases by a factor of 6.

Gay-Lussac's Law
According to Gay-Law, Lussac's the gas molecules move more quickly as the temperature rises as long as the volume of the container holding the gas remains constant. The pressure then rises as a result of an increase in the number of shocks striking the walls. In other words, the relationship between a gas's pressure and temperature is direct.
In conclusion, when the volume remains constant, the pressure of the gas increases as the temperature rises. Additionally, gas pressure falls as temperature drops.

But as mentioned in question Solar Constant is received at a location if insolation is measured at 343
W/m^2
Therefore,
Percentage of the Solar Constant is received = (343 / 1372) × 100
= 25 %

When the voltage applied at the drain terminal is small, the mosfet channel behaves like a:___.
When the voltage applied at the drain terminal is small, the mosfet channel behaves like a Current controlled voltage source.
An active load is created when the drain and gate of a MOSFET are coupled together, creating a two-terminal device known as a "diode-connected transistor." An active load is created when the drain and gate of a MOSFET are coupled together, creating a two-terminal device known as a "diode-connected transistor." The drain-source (or source-drain) connection of the MOSFET can be made open or connected by adjusting the charge distribution between the gate and body. Both NMOS and PMOS transistors function as switches in this way, but the specifics of the operation vary between the two types.

Furthermore, how can it calculate its profit if revenue is in u.s. currency and most of its costs are in canadian currency?
A company can calculate its profit by using the foreign currency exchange rates prevailing in the market. The cost incurred in foreign currency can be converted into domestic currency first. The spot rates prevailing in the market can be used for such conversion. Once the expenses are converted into the domestic currency, the profits can be computed in the normal manner as now both the revenues and the cost are in domestic currency.
What is meant by foreign exchange rate?Foreign Exchange Rate is defined as the cost of the residential currency with regard to another currency. The reason of foreign trade is to compare one currency with another for appearing their relative values.
Foreign exchange rate can also be said to be the rate at which one currency is traded with another or it can be said as the price of one currency that's expressed in terms of another currency.
Exchange rates of a currency can be either fixed or floating. Fixed trade rate is decided by the central bank of the nation whereas the floating rate is decided by the flow of market request and supply.

What was larry's acceleration at take-off? assume a take-off mass of 210 lb (including helium)
Larry's acceleration at take-off is 23.38 m/s.
Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both.
Formula for acceleration ->
a= Δu / Δt = [tex]u_{f} - u_{i}[/tex] / Δt
Now, Given
m = 200Lb = 90.71kg
D = 2m / s
[tex]N_{0}[/tex] = 42
volume of balloon = (4/3)π[tex]r^{3}[/tex]
= 4/3 * pi * (1) ^ 3 = 4 . 188 m t ^ 3
Total volume 42 x 4-188 = 175.9 mt3
Buoyancy force = P g x volume of air displaced
= 1.229 * 9.81 * 175 * 9
= 2121N
Force = mass x acceleration
acceleration = F /m = 2121 / 96.71 = 23.38 m/s
Therefore, the required acceleration is 23.38 m/s.
