Explanation:

The quality of the saturated liquid-vapor mixture in the closed piston-cylinder device is 0.888.

Using the given information, we can first determine the initial state of the water using a table of thermodynamic properties of water. Since the water is initially a saturated vapor at 300 kPa, its specific volume can be found to be 0.1473 m3/kg.

Next, we know that the water is cooled isobarically (at constant pressure) until it becomes a saturated liquid-vapor mixture. At this stage, the specific volume of the water is given to be 0.1 m3/kg. We can use this value to determine the quality (x) of the mixture, which is the fraction of the mixture that is in the vapor phase.

The specific volume of the mixture can be expressed as:

v_mix = x * v_g + (1 - x) * v_f

where v_g and v_f are the specific volumes of the vapor and liquid phases, respectively. At the saturated state, the specific volume of the vapor and liquid phases are equal, so we can simplify the equation to:

v_mix = v_f = v_g

Solving for x, we can rearrange the equation to:

x = (v_mix - v_f) / (v_g - v_f)

Plugging in the values, we get:

x = (0.1 - 0.00104) / (0.1943 - 0.00104) = 0.888

Therefore, the quality of the saturated liquid-vapor mixture in the closed piston-cylinder device is 0.888.

The total distance traveled by the cyclist between 0 and 6.0 s is 37.435 m.

A motorcyclist who is moving along an x axis directed toward the east has an acceleration given by a = (6.1 - 2.0t) m/s2 for 0 t 6.0 s. At t = 0, the velocity and position of the cyclist are 3.1 m/s and 7.3 m. We can use the following kinematic equations of motion to solve the problem: v = u + at

Here, v, u, a and t represent final velocity, initial velocity, acceleration, and time, respectively. s = ut + 0.5 at²Here, s, u, a, and t represent displacement, initial velocity, acceleration, and time, respectively.

(a)To find the maximum speed of the cyclist, we first need to find the time at which the acceleration becomes zero. Therefore, 6.1 - 2.0t = 0⇒ t = 3.05s

Now, we can find the maximum speed using the kinematic equation: v = u + at= 3.1 + (-2.0 × 3.05)= -3.8 m/s

Therefore, the maximum speed achieved by the cyclist is 3.8 m/s.(b)Total distance covered by the cyclist between 0 and 6.0 s is given by the area under the velocity-time graph in the given interval.

The velocity of the cyclist as a function of time is given by the following equation: v = 3.1 + (6.1 - 2.0t)⇒ v = 3.1 + 6.1 - 2.0t⇒ v = 9.2 - 2.0t

So, we can draw a velocity-time graph using the above expression. We have, Taking the area under the curve between 0 to 6.0 s, we get the total distance traveled by the cyclist between the time interval of 0 to 6.0s. We can find this area by breaking it down into two areas.

Area 1: It is a rectangle of width 3.05 s and height 3.8 m/s.

Area 2: It is a trapezium with the following parameters: Height = (9.2 - (-3.8)) m/s = 13 m/s Width = (6 - 3.05) s = 2.95 s Area of trapezium = 0.5 × (3.8 + 13) × 2.95= 25.575 m²

Total distance traveled = area of rectangle + area of trapezium= 3.05 × 3.8 + 25.575= 37.435 m

Therefore, the total distance traveled by the cyclist between 0 and 6.0 s is 37.435 m.

Increasing the pressure would increase the boiling point of water at 100°C and at 1 atmospheres as increasing pressure will cause molecules to come close together and boil  at a higher temperature.

Pressure is defined as the force applied on an object perpendicular to it's surface per unit area over which it is distributed.Gauge pressure is a pressure which is related with the ambient pressure.

There are various units by which pressure is expressed most of which are derived units which are obtained from unit of force divided by unit of area . The SI unit of pressure is pascal .

The object was moved 46.3 cm closer to the mirror.

Let the object distance be 'u' and the image distance be 'v' for the first case where the image is twice the size of the object.

Using the mirror formula:

1/f = 1/v + 1/u

Since the mirror is concave, the focal length is negative, f = -v/2.

Plugging this into the formula gives:

-2/v = 1/v + 1/u

-3/v = 1/(v+70.9) + 1/u

Solving these two equations simultaneously, we get:

u = -46.3 cm

The two possible angles θ1 and θ2 between the rifle barrel and the horizontal such that the bullet will hit the target are given by:θ1 = (-1/2) [arctan(2a/(-b - √(b^2 - 4ac))) + π/2 + nπ] andθ2 = (-1/2) [arctan(2a/(-b + √(b^2 - 4ac))) + π/2 + nπ]where n is an integer.

In the given case, the figure shows an exaggerated view of a rifle that has been sighted in for a 91.4-meter target. Let the muzzle speed of the bullet be v0 = 427 m/s.

Now, we are required to find the two possible angles θ1 and θ2 between the rifle barrel and the horizontal such that the bullet will hit the target.

It is known that the horizontal displacement of the bullet from the gun can be given by the equation: x = v0 t cosθ ..........(i)and the vertical displacement of the bullet from the gun can be given by the equation: y = v0 t sinθ - (1/2) g t^2..........(ii).

Here, t is the time of flight of the bullet and g is the acceleration due to gravity.

As the bullet hits the target, its final vertical displacement from the gun is equal to the height of the target, i.e.,y = 91.4m.Now, we can substitute equations (i) and (ii) in place of t and y in equation (ii) to get:x tanθ - (g/2v0^2) x^2 sec^2θ = 91.4 ..........(iii)This is a quadratic equation in tanθ.

On solving this equation using the quadratic formula, we get:tanθ = [-b ± √(b^2 - 4ac)]/2aWhere,a = -gx^2/(2v0^2) = -4.9x^2/v0^2, b = x, and c = -91.4.

Rearranging the terms, we get:2a tanθ^2 + b tanθ - 91.4 = 0On substituting the given values, we get:2(-4.9x^2/v0^2) tanθ^2 + x tanθ - 91.4 = 0θ1 and θ2 are the two possible angles which can be found by solving the above quadratic equation.

Using the trigonometric identity given in the hint, we can write: sin 2θ = 2 sinθ cos θ = 2 tanθ/ (1 + tan^2θ)Now, we can substitute tanθ = (-b ± √(b^2 - 4ac))/2a in the above equation to get: sin 2θ = (-4bx ± 2x√(b^2 - 4ac))/(b^2 + 4a^2)Now, we can substitute the given values to get: sin 2θ1 = -0.999sin 2θ2 = 0.998.

Thus, we get two values of sin 2θ, one is close to -1 and the other is close to 1. As sin 2θ = -1 when 2θ = -π/2 + nπ and sin 2θ = 1 when 2θ = π/2 + nπ, where n is an integer, we get two possible values of θ for each of these two cases.

Hence, the two possible angles θ1 and θ2 between the rifle barrel and the horizontal such that the bullet will hit the target are given by:θ1 = (-1/2) [arctan(2a/(-b - √(b^2 - 4ac))) + π/2 + nπ] andθ2 = (-1/2) [arctan(2a/(-b + √(b^2 - 4ac))) + π/2 + nπ]where n is an integer.

As one of these angles is so large that it is never used in target shooting, we only need to consider the other angle.

Assuming the cooking time for a slice of toast is 2 minutes (120 seconds), the electrical energy consumed by a 1,575 W, it would require 189,000 joules of electrical energy.

The electrical energy (E) can be calculated using the formula:

E = P × t

Where:

E = Electrical energy in joules (J)

P = Power of the toaster in watts (W)

t = Cooking time in seconds (s)

Substituting the given values:

E = 1,575 W × 120 s

Calculating the product:

E = 189,000 J

Velocity is the pace and direction of an object's movement, whereas speed is the time rate at which an object is travelling along a path. In other words, velocity is a vector, whereas speed is a scalar value.

For instance, 50 km/hr west denotes the velocity of a car whereas 50 km/hr (31 mph) denotes the speed at which it is moving down a route.

The average speed of an object is determined by dividing the distance traveled by the amount of time it takes the object to reach the distance.

The escape velocity of the planet = 2 Escape velocity of the earth
