The manufacturer should manufacture 130 units per week to minimize the cost. To find the number of units that should be manufactured to minimize the cost, we need to use the concept of calculus and find the minimum point of the function c(x).

First, we need to take the derivative of the function c(x) with respect to x: c'(x) = 0.3x - 39

Next, we set c'(x) = 0 to find the critical point(s) of the function:
0.3x - 39 = 0
0.3x = 39
x = 130

Now, we need to check whether this critical point is a minimum point or not. To do this, we take the second derivative of c(x) with respect to x:
c''(x) = 0.3
Since c''(x) is positive for all values of x, we can conclude that the critical point x = 130 is indeed a minimum point.

Therefore, the manufacturer should manufacture 130 units per week to minimize the cost.

The water budget equation for the Creek drainage basin is: Precipitation = Stream discharge + Evapotranspiration ± Change in storage.

To develop the water budget equation for this problem, we need to account for the inputs and outputs of water in the Creek drainage basin. The water budget equation can be expressed as,

P = Q + ET ± ΔS

P = Precipitation input (mm)

Q = Stream discharge (m³/s)

ET = Evapotranspiration (mm)

ΔS = Change in storage (mm)

First, let's convert the units of the given values,

Precipitation input (P) = 550 mm

Stream discharge (Q) = 1.8 m³/s

Now, let's determine the evapotranspiration (ET) and change in storage (ΔS) terms. However, the problem doesn't provide information about ET, so we cannot calculate it accurately. The problem doesn't provide information about ΔS, so we cannot calculate it accurately.

Given these limitations, we can write the simplified water budget equation for this problem,

550 mm = 1.8 m³/s + ET ± ΔS

Please note that without information about evapotranspiration and changes in storage, we cannot fully determine the water budget for the Creek drainage basin.

From the calculation, there is a net force that acts on the car and then the acceleration that is produced by the net force is 0.296 m/s^2.

The term net force refers to the force that is acting on an object that makes it to move. We have to recall that the force of friction is the force the limits the motion of an object. In other words, it is the force of friction that makes a body not to be able to move and this must be overcome by the forward force when it is greater than the friction force.

Now;

Mass of the car = 1352 kg

Forward force = 7820 N

Coefficient of friction = 0.56

Frictional force = μmg

= 0.56 * 1352 kg * 9.8 m/s^2

= 7419.8 N

Net force = Forward force - Frictional force

= 7820 N -  7419.8 N

= 400.2 N

Then;

Net force = ma

We have the free body diagram below:

To find the distance, let's first find the x-component and y-component of the velocity.

x-component:

y-component:

To find the distance travelled west, we are to find the distance in the x direction.

Apply the formula:

Where:

|Vx| = |-2.378 m/s| = 2.378 m/s

t is the time is seconds = 25 x 60 = 1500 seconds

Thus, we have:

The distance traveled west in 25 minutes is 3.6 km.

• (b) How far north has the sailboat traveled in 25 minutes.

Here, we are to find the vertical distance using the y-component.

Apply the formula:

Where:

Vy = 2.141 m/s

Thus, we have:

The sailboat traveled 3.2 km in the north direction.

ANSWER:

(a) 3.6 km

As the height of the hole increases, the velocity of the stream increases, results in a higher distance from the beaker. Therefore, the distance of the stream from the hole Y will be less than that from X thus, less than 5 cm is correct.

The speed of stream can be determined using the height and acceleration due to gravity g. We can use the equation for velocity using the parameters g and h.

v = √2gh

Therefore, as the height h increases, v increases.

Similarly the distance s = vt

therefore, the distance increases with v.

Here, the hole x is above the hole Y. Then the stream from X will have the greater speed and it covers greater distance (5 cm )from the beaker. Stream from Y slow compared to that in X hence covers a distance less than 5 cm. Hence, option 2 is correct.

The angular velocity of a rigid body rotating in the x-y plane can be represented as a vector perpendicular to the plane of rotation and pointing in the direction of rotation.

For a counterclockwise (CCW) rotation, the direction of the angular velocity vector is given by the right-hand rule, which states that if you curl the fingers of your right hand in the direction of rotation, your thumb points in the direction of the angular velocity vector.

For a rigid body rotating CCW at 20 rad/s on the x-y plane, the angular velocity vector can be represented as:

w = 20 * i (where i is the unit vector in the x-direction)

This means that the angular velocity vector points in the positive x-direction, perpendicular to the x-y plane.

Explanation:

The EMF of a cell represents its maximum potential difference, while the potential difference across the cell when passing a current through an external resistance is reduced due to the internal resistance of the cell.

The electromotive force (EMF) of a cell refers to the maximum potential difference that the cell can provide when it is not connected to any external circuit. It is essentially the voltage produced by the chemical reactions occurring within the cell. On the other hand, the potential difference across the cell when it is passing a current through an external resistance is often lower than the EMF.

This difference in values can be attributed to the internal resistance of the cell. When a current is drawn from the cell, it encounters resistance within the cell itself due to factors such as the resistance of the electrolyte and the internal structure of the cell. This internal resistance causes a voltage drop within the cell, reducing the potential difference across the external circuit.

According to Ohm's Law (V = I * R), when current flows through a resistance (R), a voltage drop (V) occurs. In this case, the internal resistance of the cell causes a voltage drop within the cell itself. Hence, the potential difference across the external resistance is slightly lower than the EMF of the cell.

For cadmium, Cd, the heat of fusion at its normal melting point of 321 °C is 6.1 kJ/mol. The entropy change when 2.16 moles of solid Cd melts at 321 °C, 1 atm is 22.2 J/K.

To calculate the entropy change when 2.16 moles of solid Cd melts at 321 °C, we need to use the formula:
ΔS = ΔH_fus / T
Where ΔH_fus is the heat of fusion (6.1 kJ/mol) and T is the melting point in Kelvin (594 K).
First, we need to convert the moles of Cd to grams:
2.16 moles Cd x 112.41 g/mol = 242.8 g Cd
Next, we can use the heat of fusion to calculate the amount of energy required to melt this amount of Cd:
ΔH = n x ΔH_fus = 2.16 mol x 6.1 kJ/mol = 13.18 kJ
Finally, we can plug these values into the entropy change formula:
ΔS = ΔH / T = 13.18 kJ / 594 K = 22.2 J/K
Therefore, the entropy change when 2.16 moles of solid Cd melts at 321 °C, 1 atm is 22.2 J/K.

No, a 10msun black hole is not larger than a 1msun black hole. The size of a black hole is determined by its mass, and a 10msun black hole is simply ten times more massive than a 1msun black hole.

However, both black holes have a singularity (the point of infinite density) that is infinitely small and surrounded by an event horizon (the point of no return) that expands proportionally to the mass of the black hole. Therefore, both black holes have the same "size" in terms of their event horizon.
1. The term "Msun" represents a unit of mass, specifically the mass of the Sun. So, a 1Msun black hole has the mass of one Sun, while a 10Msun black hole has the mass of 10 Suns.
2. A black hole's size is typically characterized by its event horizon, which is the boundary beyond which nothing, not even light, can escape its gravitational pull.
3. The size of a black hole's event horizon (also known as the Schwarzschild radius) is directly proportional to its mass. Therefore, a black hole with a higher mass will have a larger event horizon.

In summary, a 10Msun black hole has a larger event horizon and is thus larger than a 1Msun black hole.

This formula shows that the energy stored on a parallel plate capacitor is directly proportional to the capacitance of the capacitor. Therefore, option C accurately describes the energy stored on a parallel plate capacitor.

Option A is incorrect because the energy stored is directly proportional to the potential difference across the capacitor, not inversely proportional to the charge stored.

Option B is incorrect because although the energy stored is related to the potential difference across the capacitor, it is not directly proportional to it.
