The average velocity can be calculated as 3455.8 m/s.
What is average velocity?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)
= (2 * pi * 5.00 m) * (110 revolutions per minute)
= 3455.8 m/s

A bungee jumper with mass 65.0 kg jumps from a high bridge. After arriving at his lowest point, he oscillates up and down, reaching a low point seven more times in 43.0 s. He finally comes to rest 25.0 m below the level of the bridge. Estimate the spring stiffness constant and the unstretched length of the bungee cord assuming SHM.
The spring stiffness constant is 26.2 N/m and the unstretched length of the bungee cord is 0.69 m.
What is spring constant?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
l₁ = 0.69 m
Thus, The spring stiffness constant is 26.2 N/m and the unstretched length of the bungee cord is 0.69 m.

The rate of change of angle of elevation between the radar station and airplane is - 83.33rad / 109hr
The plane is traveling at 500 mph.
Over the radar station, the aircraft is flying at a height of 6 miles.
the airplane's distance after 10 minutes
distance = speed x time
= 500 mil/hr x 10 min
Since the speed is hour let us convert it to mins
= 500 x 10 x 1/60
= 5000 / 60
= 83.33 miles
Let's thus assume that the aircraft is exactly 3 miles above the radar station at that location.
therefore it is possible to determine the elevation angle between the radar station and the aircraft by
O represents the side that is opposed to the angle of elevation, and tan = O / A.
The angle of elevation's neighboring side is designated as A.
However, in order to determine the rate of change in angle of elevation, let's distinguish between the two sides with respect to time.
sec²∅ d∅/dt = (AdO/dt - O dA/dt)/ A²
d∅/dt =( A (AdO/dt - O dA/dt)) / sec²∅A²
d∅/dt =( 83.33(0)- 10(500mil/hr) ) / sec²( 83.33)²
Since the height will remain constant, the derivative of altitude will be zero while the airplane's travel distance varies over time.
d∅/dt =( 83.33(0)- 10(500mil/hr) ) / 109/100( 83.33)²
We had found the value of sec²θ = (hyp/adj)²
d∅/dt =- 5000rad / 109hr

you are on a desert island and there are two identical black boxes. one of them is a voltage source, the other is a current source. how can you tell which is which?
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.

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.

What fraction of its electrons have been removed? the density of copper is 8900 kg/m3.
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
The given question is incomplete. The complete question is 'A 2.0-mm-diameter copper ball is charged to 40 nC.'

Describe a situation in which work is done on an object.
Answer:
Explanation:
A situation in which work is done on an object would be when a mechanic is performing maintenance on a vehicle. The mechanic would be responsible for inspecting the vehicle, replacing necessary parts, and performing any necessary repairs. This would involve using tools such as wrenches, screwdrivers, and other specialized equipment to remove, replace, and repair the various components of the vehicle. Once the maintenance is completed, the mechanic would test the vehicle to make sure it is in proper working order before returning it to the owner.
Answer:
In order to accomplish work on an object there must be a force exerted on the object and it must move in the direction of the force. If either of those conditions are not met, then there is no work.
Explanation:
Work done by the gravity on a rocket going perpendicular upwards is an example of negative work.

When a car is at the top of a circular path, there are two forces acting on it. What is the Net Force towards the center of the circle
In order for the car to move inside the circular route, the net force acting on it at the peak of the motion is at the circle's centre.
Newton's second law states that acceleration requires a net force that is not zero. An item travelling along a circular path experiences acceleration that is focused on the circle's centre. As a result, the centre is also the direction of the net force. The centripetal force is a common name for this net force.
The centripetal force needed for circular motion is produced as an car turns by the friction force acting on the car's rotated wheels.
