C = 9.70 + 0.46(w - 5). This is a linear equation where C is the total cost, 9.70 is the fixed base fee, w is the weight of the package in pounds, and 0.46 is the additional cost per pound over 5 lbs. The term (w - 5) represents the weight of the package that exceeds 5 lbs, and the 0.46 is multiplied by this value to calculate the additional cost.

A linear equation is an equation that can be written in the form of y = mx + b, where y is the dependent variable, x is the independent variable, m is the slope of the line, and b is the y-intercept. In this equation, the slope represents the rate of change of the dependent variable with respect to the independent variable, and the y-intercept is the point where the line crosses the y-axis. Linear equations can be represented graphically as a straight line, and the slope and y-intercept can be used to determine the equation of the line.

In the case of the cost equation provided, C is the dependent variable, and w is the independent variable. The slope is represented by the coefficient of w, which is 0.46, which means the cost will increase by 0.46 dollars for every pound added to the weight of the package.

The average velocity can be calculated as 3455.8 m/s.

Average velocity is the rate at which an object's position changes over time. It is calculated by taking the displacement (change in position) over the change in time. Average velocity can be thought of as the object's overall speed in a certain direction.

The average velocity of the blade tip in the helicopter's frame of reference can be calculated by taking the circumference of the circle of rotation (2*pi*5.00 m) and dividing it by the time it takes for the blade to make one revolution (1/110 revolutions per minute). So the average velocity can be calculated as:
Average velocity = (2 * pi * 5.00 m) / (1/110 revolutions per minute)

Answer:

c

Explanation:

The position vs. time graph of an object with constant acceleration is a parabolic curve. The curvature is upward for positive acceleration and downward for negative accelerations.

Answer:

C

Explanation:

The relationship between distance and acceleration is dependent of the square of the time the unit is accelerating:  (1/2)*a*t^2, where a is the acceleration and t is the time.  Since the time is squared, and it falls on the x axis, each increse in time produces a squared impact on distance.

The noise from a 1.0 t mri scanner is five times more intense than the noise from a vacuum cleaner. Intensity of sound is measured as the quantity of sound per unit of perpendicular space.

W/m2, the SI unit for sound intensity, indicates I, the direction in which sound waves travel (watt per square meter). Sound intensity is often measured in Watts per square metre (W/m2). In order to determine how much sound energy a certain amount of noise emits in the air where the listener is standing, the standard definition incorporates calculation.

The work done by the gravitational force on rock 1 can be calculated using the work-energy theorem. This theorem states that the net work done on an object is equal to the change in its kinetic energy.

Gravitational force is the attractive force between two objects that is proportional to their masses and inversely proportional to the square of the distance between them. It is the weakest force in nature and is the reason why objects with mass are attracted to each other. This force was first described by Isaac Newton in his law of universal gravitation, which states that the force between two objects is proportional to the product of their masses and inversely proportional to the square of the distance between them.

Since the rock is launched from rest at a height of h0 and then returns to the same height, its kinetic energy does not change and therefore the net work done on the rock is zero. This means that the work done by the gravitational force on the rock is also zero, since the only force acting on the rock is the gravitational force.

The spring stiffness constant is 26.2 N/m and the unstretched length of the bungee cord is 0.69 m.

The definition of the spring constant is related to Hooke's law and simple harmonic motions. In order to define the spring constant and comprehend how it operates, we must first examine Hooke's law. As long as the applied load is below the elastic limit, the theory of elasticity states that when a load is applied to a spring, it will naturally extend proportionally. We now understand that when an object is subjected to force, it tends to deform in some way.

Given that;

mass of the bungee jumper, m = 65 kg

time of motion, t = 43 s

distance to come to rest, d = 25 m

The period of oscillation of bungee jumper is calculated as;

T = t/n

T = 43/7

T = 6.14 s

The spring stiffness constant is calculated as;

T = [tex]$ 2\pi \sqrt{\frac{m}{k} }[/tex]

[tex]$ 6.14 = 2(\frac{22}{7}) \sqrt{\frac{25}{k} }[/tex]

k = 26.2 N/m

The extension of the cord is calculated as;

F = kx

mg = kx

x = mg/k

x = [tex]$\frac{\left(65\times 9.8\right)}{26.2}[/tex]

x = 24.31 m

The unstretched length of the bungee cord is calculated as;

Δx = l₂ - l₁

l₁ = l₂ - Δx

l₁ = 25 - 24.31

One way to determine which black box is a voltage source and which is a current source is by measuring the voltage and current at different points in the circuit, or using multimeter to measure voltage and current.

A voltage source will maintain a constant voltage across its terminals regardless of the current flowing through it, while a current source will maintain a constant current through its terminals regardless of the voltage across it.

Another way is to observe the behavior of the circuit when a load is connected. If the circuit behaves as if the voltage across the terminals is constant, it is likely a voltage source. If the circuit behaves as if the current through the terminals is constant, it is likely a current source.

Additionally, you can use a multimeter to measure the open-circuit voltage and short-circuit current of the black boxes.

Speed is defined as the rate of change of position of object in any direction. Speed is measured as the ratio of distance to the time in which that distance was covered.

The circumference of a circle is 2 * pi * radius, where pi is approximately 3.14. Therefore, circumference of the circle with a radius of 2700 m is:

2 * pi * 2700 m = 16,800 m

Given, constant speed of 180 m/s

As, distance = speed * time

So, time = distance / speed

The fraction of its electrons which have been removed is calculated to be 0.02442 × 10⁻⁹.

Given that,

Diameter of the copper ball = 2.00 mm = 0.002 m

Charge on ball = 40 nC = 40 × 10⁻⁹ C

Density of copper = 8900 Kg/m³

Now let us calculate,

The number of electrons removed, n = charge on the ball/charge of an electron

Charge on a single electron = 1.6 × 10⁻¹⁹ C

Thus, n = (40 × 10⁻⁹)/(1.6 × 10⁻¹⁹) = 25 × 10¹⁰ electrons

Mass of copper ball = volume × density = 4/3 π × (d/2)³× 8900 = 4/3 π × (0.02/2)³× 8900 = 0.03726 gm

Molar mass of copper = 63.546 g/mol

Number of mol of copper in  0.03726 grams = 0.03726 / 63.546 = 5.86 × 10⁻⁴ mol

1 mol of a substance has = 6.022 × 10²³ atoms

5.86 × 10⁻⁴ mol of copper contains = 5.86 × 10⁻⁴ × 6.022 × 10²³ atoms = 35.88 × 10¹⁹ atoms

A neutral copper atom has 29 electrons.  

So, number of electrons in ball = 29 × 35.88 × 10¹⁹ = 1023.37 × 10¹⁹ electrons.

Hence, the fraction of electrons removed = (25 × 10¹⁰)/(1023.37 × 10¹⁹) = 0.02442 × 10⁻⁹
