The average acceleration of the ball, while it is in contact with the wall, is -3969.27 m/s².

Acceleration is the rate of change of velocity per unit of time. Its S.I. unit is m/s². It is equal to the change in velocity divided by the time taken to change the velocity.

Acceleration a =  Change in velocity/ Time taken

Given in the question

Initial Velocity = u = + 20.6 m/s ( towards the wall is positive direction )

Final Velocity = v = - 11.948 m/s (away from the wall is negative direction)

Change in Velocity = Final Velocity - Initial Velocity

                                = (- 11.948) - ( + 20.6)

                                = -11.948 - 20.6

                                = -32.548 m/s

So Change in velocity = 32.548 m/s

Time Taken = Time of contact with the wall

                    = 0.0082 seconds

Put in the Formula: a =  Change in velocity/ Time taken

a = -32.548/0.0082

a = -3969.27 m/s²

Therefore the average acceleration of the ball, while it is in contact with the wall, is -3969.27 m/s².

Newton's Third Law

Explanation:

According to Newton's third law of motion, forces always act in equal but opposite pairs. Another way of saying this is for every action, there is an equal but opposite reaction. This means that when you push on a wall, the wall pushes back on you with a force equal in strength to the force you exerted.

The magnitude of car's displacement is 17.78 m.

Given that, distance travelled due north is 11.8 m

Distance travelled due east is 13.3 m

As it is said that the car travels north and then east, it forms the two sides of a right-angled triangle. The magnitude of third side is the magnitude of car's displacement.

From Pythagoras theorem, the expression for car's displacement can be written as,

AC² = AB² + BC²

where, AB and BC are the sides of the right triangle

AC is the displacement of the car

Making AC as subject, we have,

AC = √(AB² + BC²) = √(11.8² + 13.3²) = √(139.24 + 176.89) = 17.78 m

Thus, the magnitude of car's displacement is 17.78 m.

To make the study blind, the researchers should randomly assign participants to two groups: one wearing the magnetic bracelet and the other wearing a placebo bracelet without magnetic properties. In a double-blind study, both the participants and the researchers measuring motion sickness should be unaware of which bracelet each participant is wearing.

In a blind study, the researchers aim to eliminate bias by preventing participants from knowing whether they are receiving the actual treatment or a placebo. To achieve this, the research team should randomly assign participants to two groups. One group will wear the magnetic bracelet, while the other group will wear a placebo bracelet that looks identical but lacks any magnetic properties. The participants should not be informed about the nature of the bracelets to ensure unbiased results.

To conduct a double-blind study, both the participants and the researchers who are assessing motion sickness levels need to be unaware of which bracelet each participant is wearing.

This additional measure prevents the researchers from inadvertently influencing the outcome by treating participants differently based on their bracelet assignment. By keeping both the participants and the researchers blind to the bracelet conditions, the study can minimize bias and ensure more reliable results.

Answer:

Approximately \(2.69\; {\rm A}\).

Explanation:

Ensure that all values are measured in standard units. Charge should be measured in coulombs, while time should be measured in seconds:

\(\begin{aligned}t &= 3.0\; {\rm hr} \times \frac{3600\; {\rm s}}{1\; {\rm hr}} = 10800\; {\rm s}\end{aligned}\).

Electric current \(I\) is the rate of flow of electric charge.

In order to find the electric current, divide electric charge \(q\) by the time \(t\) required to transfer these charge. If charge \(q\!\) is measured in coulombs and time \(t\!\) is measured in seconds, the unit of current \(I\)would be amperes:

\(\begin{aligned}I & = \frac{q}{t} \\ &= \frac{29000\; {\rm C}}{10800\; {\rm s}} \approx 2.69\; {\rm A}\end{aligned}\).

One of the options that are the most appropriate choice of Gaussian surface to use in this problem is a finite closed cylinder whose axis coincides with the axis of the rod and whose cross section has radius r.

This is because the charged cylinder which is of infinite length as mentioned and hence there won't be any electric flux coming out of the top and bottom flat surfaces.

Now, to find out the magnitude of the electric field, we shall have to apply Gauss's law,

The orbital velocity an aircraft orbiting around a heavenly body is found as follows;

At the orbital velocity, \(F_G\) = \(F_C\)

Where;

\(F_G\) = The gravitational force = \(\dfrac{G \cdot M \cdot m}{R_E^2}\)

\(F_C\) = The centripetal force = \(\dfrac{m \cdot v_0^2}{R_E}\)

According to Hawthorne, there were few physicians in Boston due to the Puritan belief that physical ailments were a punishment from God and therefore should not be interfered with. Additionally, medical education was not highly valued in Puritan society, leading to a shortage of trained doctors in the area.

According to Nathaniel Hawthorne, the acclaimed American author of the 19th century, there is no explicit statement suggesting that there were few physicians in Boston. Hawthorne is renowned for his literary works like "The Scarlet Letter" that explore various aspects of Boston society. However, his writings do not specifically address the number of physicians in Boston.

It is important to recognize that the availability of physicians and medical professionals can differ based on historical circumstances and other factors within a particular city or region.

Since the mass is attached to an ideal spring, the system will undergo simple harmonic motion. The maximum distance the mass will fall is equal to the amplitude of the oscillation.

The period of oscillation can be calculated as:

T = 2π√(m/k)

where m is the mass and k is the spring constant.

Substituting the given values, we get:

T = 2π√(0.7 kg / 86 N/m) ≈ 0.887 s

The maximum distance the mass will fall is equal to half the amplitude of the oscillation, which can be calculated using the equation:

x = A cos(2πt/T)

where x is the displacement of the mass from its equilibrium position at time t, and A is the amplitude of oscillation.

At the maximum displacement, cos(2πt/T) will be equal to -1. Therefore,

A = -x

The velocity of the mass at the maximum displacement will be zero. Therefore, the total energy of the system will be equal to the potential energy at the maximum displacement:

1/2 k A^2 = m g A

where g is the acceleration due to gravity.

Solving for A, we get:

A = (m g / k) = (0.7 kg x 9.81 m/s^2) / 86 N/m ≈ 0.0807 m

Therefore, the maximum distance the mass will fall is approximately 0.0807 m.

A person weighing 60 kg can lift a maximum weight of 300 kg with a class one lever if the force arm is 1.2 m long, and the resultant arm is 20 cm long. Here is an explanation of how this answer is obtained First, we need to calculate the mechanical advantage of the lever.

The mechanical advantage of a class one lever is given by the ratio of the length of the force arm to the length of the resultant arm:MA = Force arm length / Resultant arm lengthIn this case, the force arm length is 1.2 m and the resultant arm length is 20 cm = 0.2 m, so:MA = 1.2 / 0.2MA = 6Next, we need to use the formula for calculating the maximum weight that can be lifted with a lever: Maximum weight = Effort force x Mechanical advantageIn this case, the effort force is the force that the person can exert, which we can assume is equal to their body weight.

The effort force is 60 kg x 9.8 m/s² (acceleration due to gravity) = 588 N.Maximum weight = 588 N x 6Maximum weight = 3528 NFinally, we convert this force to weight by dividing by the acceleration due to gravity:Maximum weight = 3528 N / 9.8 m/s²Maximum weight = 360 kgSo, a person weighing 60 kg can lift a maximum weight of 360 kg with a class one lever if the force arm is 1.2 m long, and the resultant arm is 20 cm long.

(a) 0.2 A.

(b) 100 A.

(c) 10 e^(-2t) A.

(d) 0.5 sin(5t) A.

(e) 0 A.

To determine the magnitude of the current flowing through a conductance, we need to use Ohm's Law, which states that the current (I) flowing through a conductor is equal to the voltage (V) across it divided by its conductance (G).

Ohm's Law equation: I = V / G

Given the voltage across the conductance in each case, we can calculate the current magnitude using the given conductance values.

(a) Voltage = 2 mV, Conductance = 10 mS (10 ms)

I = (2 mV) / (10 mS)

I = 0.2 A

The magnitude of the current flowing through the conductance is 0.2 A.

(b) Voltage = -1 V, Conductance = 10 mS (10 ms)

I = (-1 V) / (10 mS)

I = -100 A

The magnitude of the current flowing through the conductance is 100 A.

(c) Voltage = 100 e^(-2t) V, Conductance = 10 mS (10 ms)

I = (100 e^(-2t)) / (10 mS)

I = 10 e^(-2t) A

The magnitude of the current flowing through the conductance is 10 e^(-2t) A.

(d) Voltage = 5 sin(5t) V, Conductance = 10 mS (10 ms)

I = (5 sin(5t)) / (10 mS)

I = 0.5 sin(5t) A

The magnitude of the current flowing through the conductance is 0.5 sin(5t) A.

(e) Voltage = 0 V, Conductance = 10 mS (10 ms)

I = (0 V) / (10 mS)

I = 0 A

The solubility of silver carbonate in water at 25°C is approximately

1.28 x 10⁻⁴ g/L

To calculate the solubility of silver carbonate (in water at 25°C, we need to use the solubility product constant (Ksp) and the balanced chemical equation for the dissociation of silver carbonate.

The balanced chemical equation for the dissociation of Ag2CO3 is

Ag₂CO₃(s) ⇌ 2Ag+(aq) + CO₃²-(aq)

Using the Ksp expression for Ag₂CO₃

Ksp = [Ag+]² [CO3²-]

substituting the equilibrium concentrations:

8.4 x 10⁻¹² = (2x)² * x

Simplifying the equation

8.4 x 10⁻¹² = 4x³

2.1 x 10⁻¹²  = x³

It is because the weight W = 0, due to g = a, the person falling during the free fall will therefore experience weightlessness.

A free fall is a situation where a body or an object fall solely under the influence of gravity.

Why does a person feel weightlessness during freefall​ ?

The weight of a body = mg

When a person is falling, the person will be falling with a certain acceleration. The weight W of the person will be;

W = m( a - g )

During free fall, acceleration a will be equal to acceleration due to gravity g. That is, a = g

W = m( a - a )
