For a building to maintain positive pressure with various fuel-burning appliances operating, a(n) _____ should be used.
Answer:
A fan/blower should be used
Explanation:
In a building the air pressure could be positive or negative and each if these depends on the air tightness of the building and could also be caused sometimes by wind and other factors.
When there is positive pressure, we have it that the pressure in the building is more than the outside pressure. Positive pressure also helps with an improvement in the quality of air in a building since it would take out smokes and other particulates.
Therefore to maintain positive pressure a fan or blower should be used.

the string of a helium balloon slips from your hand and rises up into the air. when this happens
When the string of a helium balloon slips from your hand and rises into the air, the balloon rises until it reaches an altitude where its weight equals that of the same volume of air.
When a helium balloon is released, it rises until it reaches an altitude where its weight equals that of the same volume of air. This is due to the principle of buoyancy.
Helium gas is lighter than air, which causes the balloon to initially ascend. As the balloon rises, the surrounding air pressure decreases, and so does the density of the air. Eventually, the balloon reaches an altitude where the density of the surrounding air matches the density of the helium-filled balloon.
At this point, the upward buoyant force acting on the balloon becomes equal to the downward gravitational force (weight) acting on the balloon. This balance of forces causes the balloon to stop rising further and instead float at a relatively stable altitude.
Option c) accurately describes this behavior, where the balloon rises until it reaches an altitude where its weight equals that of the same volume of air.
The question should be:
The string of a helium balloon slips from your hand and rises into the air. when this happens
a) the balloon rises indefinitely because helium is lighter than air
b) the balloon rises until it reaches an altitude where the air and helium densities are equal.
c) the balloon rises until it reaches an altitude where its weight equals that of the same volume of air
d) the balloon rises continually but slows down to the effect of viscosity

Off the southern coast of Andorra in the Mediterranean Sea lies the island of Duosomata (pronounced DOO-oh-so-MAH-ta). It is populated exclusively by short people and tall people. No people of average height live on the island. We can use the following predicates to say things about the people of Duosomata.
person(x)
≡
x is a person.
short(x)
≡
Person x is short.
tall(x)
≡
Person x is tall.
taller(x, y)
≡
Person x is taller than person y.
Answer the following questions by writing expressions in predicate calculus that use these predicates. Assume that quantified variables range over all possible objects, not just people, and not just people from Duosomata.
1a. (5 points.) Write an expression that means ‘‘If there are any two people, and the first person is taller than the second person, then the first person is tall, and the second person is short.’’
1b. (5 points.) Write an expression that means ‘‘At least one tall person is taller than any short person.’’
1c. (10 points.) Suppose that this is true:
¬ ∃s ∃t [person(s) ∧ person(t) ∧ short(s) ∧ tall(t) ∧ taller(s, t)]
Then prove that this is true:
∀s ∀t [(person(s) ∧ person(t) ∧ short(s) ∧ tall(t)) → ¬ taller(s, t)]
Your proof must be written as a series of steps. Each step must be an expression in predicate calculus. You must give a reason for each step.
1a. (∀x)(∀y)((person(x) ∧ person(y) ∧ taller(x, y)) → (tall(x) ∧ short(y)))
1b. (∃x)(tall(x) ∧ (∀y)(short(y) → taller(x, y)))
How can we show the proof?1c.
Proof:
Step 1:
Assume (person(s) ∧ person(t) ∧ short(s) ∧ tall(t))
Step 2:
From Step 1, we know that (person(s) ∧ person(t) ∧ short(s) ∧ tall(t)) is true.
Step 3:
Assume ¬ taller(s, t) is false, i.e. taller(s, t) is true.
Step 4:
From Step 3, taller(s, t) is true, which contradicts the assumption in (1c) that ¬ ∃s ∃t [person(s) ∧ person(t) ∧ short(s) ∧ tall(t) ∧ taller(s, t)].
Step 5:
From Step 4, it follows that ¬ taller(s, t) must be true, i.e. (person(s) ∧ person(t) ∧ short(s) ∧ tall(t)) → ¬ taller(s, t) is true.
Step 6:
Since Step 5 holds for any s and t that satisfy (person(s) ∧ person(t) ∧ short(s) ∧ tall(t)), it follows that
(∀s)(∀t)((person(s) ∧ person(t) ∧ short(s) ∧ tall(t)) → ¬ taller(s, t)) is true.
Hence, the proof is complete.

Exact answer
Answer:
The correct choice is C
Explanation A:
Shock Absorbers are best replaced in pairs if the car is relatively old. For new cars, however, one may elect to do the replacements as the need arises given that the other part is not worn out yet.
Explanation B:
It also recommended to bleed shock absorbers by moving the piston rod up and down several times. The reason is that sometimes, whilst in a horizontal position the hydraulic fluid and the gas get mixed up. This dampens the ability of the device to absorb shocks until the vehicle has been bounced up and down several times.

a high-pass rc filter is connected to an ac source with a peak voltage of 9.00 v . the peak capacitor voltage is 6.4 v
A high-pass R C filter is a filter that allows signals above a certain frequency, the cutoff frequency, to pass through while rejecting signals below that frequency. In this case, the filter is connected to an AC source with a peak voltage of 9.00 V and the peak capacitor voltage is 6.4 V.
The ratio of the peak capacitor voltage to the peak source voltage is known as the voltage gain of the filter.
The voltage gain is given by the equation:
Voltage Gain = Peak Capacitor Voltage/Peak Source Voltage
Voltage Gain = 6.4 V/9.00 V Voltage Gain = 0.711 or 71.1 %
The voltage gain is less than 1, which means that the output voltage is less than the input voltage.
This is because the high-pass RC filter attenuates the low-frequency signals while allowing the high-frequency signals to pass through. The output voltage of the filter is reduced, resulting in a voltage gain of less than 1.

Maximize Z = 3x1 + 2x2
Subject to: x1 ≤ 4, x2 ≤ 6, 3x1 + 2x2 ≤ 18, x1 ≥ 0, x2 ≥ 0.There are mainly four possible cases:Case 1: If the feasible region is bounded, and the objective function is bounded in that region, then the LPP has a unique optimal solution. Case 2: If the feasible region is bounded but the objective function is unbounded in that region, then the LPP is unbounded. Case 3: If the feasible region is empty (i.e., no feasible solution exists), then the LPP is infeasible. Case 4: If the feasible region is bounded and the objective function is not bounded in that region, then the LPP has multiple optimal solutions.Now, let's determine the case for the given LPP:Since all the constraints have non-negative coefficients, the feasible region must be in the first quadrant.

A 240-ton tugboat is moving at 6 ft/s with a slack towing cable attached to a 100-ton barge that is at rest. The cable is being unwound from a drum on the tugboat at a constant rate of 5.4 ft/s and that rate is maintained after the cable becomes taut.
The velocity of the tugboat after the cable becomes taut is:_________
The velocity when the cable becomes taut can be obtained by assuming
that the tugboat collides with a barge moving in the same direction.
Response (approximate value):
The velocity of the tugboat after the cable becomes taut is: 5.824 ft./s.How is the law of conservation of linear momentum used to calculate the speed of the tugboat?Weight of the tugboat, m₁ = 240–ton
Speed of the tugboat, v₁ = 6 ft./s
Weight of the barge, m₂ = 100–ton
Rate at which the towing cable is being unwound, v₂ = 5.4 ft./s
Required:
Velocity of the tugboat after the cable becomes taut.
Solution:
m₁ = 240 ton = 240,000 kg
m₂ = 100 ton = 100,000 kg
The velocity of the barge at rest is assumed to be the rate at which the cable is being unwound, and in the direction of the tugboat.
According to the law of conservation of linear momentum, we have;
m₁ × v₁ + m₂ × v₂ = (m₁ + m₂) × v₃
Which gives;
240 × 6 + 100 × 5.4 = (240 + 100) × v₃
1980 = 340 × v₃
Which gives;
\(v_3 = \dfrac{1980}{340} = \dfrac{99}{17} = 5\frac{14}{17} \approx \mathbf{ 5.824}\)
