If a machine allows us to apply less force to do work what is the cost?
Answers
If a machine allows us to apply less force to do work, the cost is that we must apply the force over a greater distance.
What is machine?The above is so because, according to the principle of work and energy, the amount of work done remains constant, but the force and distance can be traded off. In other words, if we decrease the force required to do a certain amount of work, we must increase the distance over which the force is applied in order to compensate.
Therefore, For example, consider a simple lever. By using a lever, we can apply less force to lift a heavy object, but we must move the lever over a greater distance in order to do so. The work done, which is the product of the force and the distance, remains constant. In this case, the force is reduced, but the distance over which it is applied is increased.

a 0.33[kg] pendulum bob is attached to a string that is 1.2[m] long. what is the change in potential energy of the system as the bob swings from point a to point b?
Answers
The change in potential energy of the system as the pendulum bob swings from point A to point B is given by ΔU = mgΔh, where m is the mass of the bob, g is the acceleration due to gravity, and Δh is the change in height between A and B.
The potential energy of a pendulum depends on its height above some reference point. In this case, we can assume that the reference point is at the lowest point of the pendulum's swing, which we'll call point C. As the bob swings from point A to point B, it rises to a height h above point C. The potential energy gained by the bob is equal to the work done on it by gravity, which is given by mgh, where m is the mass of the bob, g is the acceleration due to gravity, and h is the height above point C. To calculate the change in potential energy, we need to subtract the potential energy at point A from the potential energy at point B. At point A, the bob is at its lowest point, so its potential energy is zero. At point B, the height above point C is h = L - Lcos(θ), where L is the length of the pendulum and θ is the angle between the string and the vertical. Thus, the change in potential energy is ΔU = mg(L - Lcos(θ)), where g = 9.81 \(m/s^2\).

What would be the due point if the temperature outside increased 10 ºc?
Answers
Although the relative humidity value would drop, the dew point would remain constant (because dew point is not dependent on temperature).
The dew point is the temperature at which water vapor in the air begins to condense into liquid water droplets. The due point would increase 10 ºC if the temperature outside increased 10 ºC. The dew point is the temperature at which water vapor in the air condenses into liquid water, meaning that if the atmospheric temperature increases, the amount of water vapor that can remain in the air will also increase, and the dew point temperature will increase accordingly. In other words, the new dew point will be 10 ºC higher than it was before. This means that any water vapor in the air will begin to condense at a higher temperature than before.

A particle moves in a straight line with the given velocity v(t)=4t−²−1( in m/s). Find the displacement and distance traveled over the time interval [1/2,3].
(Use symbolic notation and fractions where needed.)
displacement:
total distance traveled:
Answers
The total distance traveled by the particle over the time interval [1/2, 3] is 19/6 units (meters). The total distance traveled by the particle over the time interval [1/2, 3] is 19/6 units (meters).
To find the displacement and total distance traveled by the particle over the time interval [1/2, 3], we need to integrate the given velocity function.
The displacement can be found by evaluating the definite integral of the velocity function with respect to time over the given time interval:
Displacement = ∫[1/2 to 3] (4t^(-2) - 1) dt
Integrating the velocity function, we get:
Displacement = [-2t^(-1) - t] evaluated from 1/2 to 3
= [(-2/(3) - 3) - (-2/(1/2) - (1/2))]
= [(-2/3 - 3) - (-4 + 1/2)]
= [-2/3 - 3 + 4 - 1/2]
= -2/3 - 5/2
= -4/6 - 15/6
= -19/6
Therefore, the displacement of the particle over the time interval [1/2, 3] is -19/6 units (meters).
To find the total distance traveled, we need to consider the absolute value of the velocity function and integrate it over the given time interval:
Total distance traveled = ∫[1/2 to 3] |4t^(-2) - 1| dt
Integrating the absolute value of the velocity function, we get:
Total distance traveled = ∫[1/2 to 3] (4t^(-2) - 1) dt
Since the absolute value of the velocity function is the same as the given velocity function, the total distance traveled is the same as the displacement, which is | -19/6 | = 19/6 units (meters).
Therefore, the total distance traveled by the particle over the time interval [1/2, 3] is 19/6 units (meters).

Calculate the fractional decrease in volume (Δ0) for seawater at 5.00 km depth, where the force per unit area is 5.00×107N/m2 .
Strategy
Equation Δ=10 is the correct physical relationship. All quantities in the equation except Δ0 are known.
Answers
Given that at a depth of 5.00 km, the force per unit area is 5.00×10^7 N/m², we can calculate the pressure at that depth.
In Example 5.6 of the mentioned chapter, we are asked to calculate the fractional decrease in volume of seawater at a certain depth. The depth is given as W meters, and we need to find the force per unit area and solve the example accordingly.
Pressure (P) is defined as force per unit area, so we have:
P = 5.00×10^7 N/m²
To express the pressure in atmospheres, we can use the conversion factor:
1 atm = 1.013×10^5 N/m²
Therefore, the pressure at 5.00 km depth is:
P = (5.00×10^7 N/m²) × (1 atm / 1.013×10^5 N/m²) ≈ 4.93×10² atm
Now, we can proceed to calculate the fractional decrease in volume (Δ₀) using the equation Δ = V/V₀ - 1, where Δ represents the fractional change in volume and V₀ is the initial volume.
Solving the equation for V, we find:
Δ = V/V₀ - 1 = 10⁻⁶
Simplifying, we get:
V/V₀ - 1 = 10⁻⁶
V/V₀ = 1 + 10⁻⁶
V/V₀ ≈ 1.000001
Therefore, Δ₀ = V/V₀ - 1 - 1 ≈ -6.00×10⁻⁶.
Since pressure is usually expressed in atmospheres, we can rewrite the result as:
Δ₀ ≈ -2.96×10⁻³ atm⁻¹.
The negative sign indicates that as the pressure increases, the volume decreases. Hence, the fractional decrease in volume of seawater at the given depth is approximately -2.96×10⁻³ atm⁻¹.

Speed and depth sensing in submarines. The Pitot and Prandtl tubes are equally effective underwater. Suppose a submarine is equipped with a forward- pointing Prandtl tube. Two independent sensors are used, one to sense static pressure and the other to sense total pressure. The density of water is assumed constant with depth, equal to 1,025 kg/m³ and independent of temperature. (a) If the submarine is expected to descend to 1,000 m, what is the span required from each pressure sensor? The maximum speed of the sub- marine is 25 knots (1 knot = 1.854 km/h). (b) Show that these two measurements are sufficient to provide both the velocity and the depth of the submarine.
Answers
To measure submarine velocity and depth underwater, a forward-pointing Prandtl tube and two pressure sensors are used. Sensor span depends on maximum depth and speed.
(a) To determine the span required for each pressure sensor, we need to consider the maximum depth and speed of the submarine. The pressure difference sensed by the Prandtl tube is equal to the dynamic pressure, which can be calculated using the formula:
Dynamic Pressure = 0.5 * ρ * V²
Where ρ is the density of water and V is the velocity of the submarine. As the maximum speed is given in knots, we need to convert it to m/s:
Maximum Speed = 25 knots = 25 * 1.854 km/h = 46.35 m/s
Assuming the submarine is moving at its maximum speed at the maximum depth, the pressure difference sensed by the Prandtl tube should be equal to the pressure difference due to the depth. The pressure difference due to the depth can be calculated using the formula:
Pressure Difference = ρ * g * h
Where g is the acceleration due to gravity and h is the depth. Substituting the given values:
Pressure Difference = 1,025 kg/m³ * 9.8 m/s² * 1,000 m = 10,049,000 Pa
Since the pressure difference sensed by the Prandtl tube is equal to the pressure difference due to depth, the span required for each pressure sensor would be half of this value, resulting in a span of 5,024,500 Pa.
(b) The two measurements, static pressure and total pressure, obtained from the independent sensors can be used to determine both the velocity and depth of the submarine. By subtracting the static pressure from the total pressure, we can obtain the dynamic pressure sensed by the Prandtl tube. From the dynamic pressure, we can calculate the velocity of the submarine using the formula mentioned earlier:
V = √(2 * Dynamic Pressure / ρ)
Once the velocity is known, the depth can be determined using the pressure difference due to depth formula mentioned earlier:
h = Pressure Difference / (ρ * g)
Therefore, by utilizing the measurements from the two independent sensors, it is possible to accurately determine both the velocity and depth of the submarine underwater.

A) Work done = Fd cosθ = 71.392 × 9.2 × cos32 = 557 J
B) the increase in thermal energy of the block-floor system = 557J since the frictional force is equal to the force in the horizontal direction.
The force acting on the body has vertical and horizontal component
the vertical component of the acting on the body = F sinθ
the horizontal component of the force acting on the block = F cosθ
since the block is moving with constant speed
then the frictional force = F cosθ in the opposite direction
