Comparing this tension value with the breaking strength of the vine (1000 N), we can see that the tension in the vine (1377 N) is indeed greater than the breaking strength. Therefore, the archeologist does make it across the river without falling in.

The archeologist's ability to swing across the river without falling in depends on whether the tension in the vine exceeds the breaking strength. To determine this, we need to analyze the forces acting on the archeologist during the swing.

At the highest point of the swing, the archeologist's velocity is perpendicular to the vine, so the tension in the vine is the force responsible for keeping him from falling. At this point, the gravitational force acting on the archeologist is equal to his weight, which can be calculated as mass times the acceleration due to gravity (m*g).

Using this information, we can calculate the tension in the vine at the highest point of the swing. The net force acting on the archeologist is the difference between the tension and the gravitational force, which is equal to mass times the centripetal acceleration (m*a). The centripetal acceleration can be calculated as (v^2)/r, where v is the velocity at the highest point and r is the length of the vine.

Now, we can set up an equation to find the tension in the vine:

Tension - \((m*g) = m*(v^2)/r\)

Plugging in the given values, we have:

Tension - \((85.0 kg * 9.8 m/s^2) = 85.0 kg * (8.00 m/s)^2 / 10.0 m\)

Simplifying, we find:

Tension - 833 N = 544 N

Rearranging the equation, we have:

Tension = 833 N + 544 N

Tension = 1377 N

Answer:

a) The velocity is 2.94m/s

b) 0.441

Explanation:

a) Assume gravity is 9.8m/s^2

Use the equation below to solve for the velocity at 0.30 seconds

\(vf=vi+at\),

vf =unknown velocity  vi= initial velocity vi=0m/s  a= 9.8m/s^2 t=0.30seconds

Step 1: Substitute the variables with the knowns

\(vf=0m/s+(9.8m/s^2)*0.30seconds\)

Step 2: Solve

\(vf=2.94m/s\)

b)

Use the equation below to solve for the displacement at 0.30 seconds

\(x=vit+\frac{1}{2} at^{2}\)

Step 1: Substitute the same variables with the knowns

\(x=\frac{1}{2}*(9.8m/s^2)*(0.30seconds)^{2}\)

Note that vi*t=0 as vi=0m/s

Step 2: Solve

The expression for the magnitude of the electric field in the upper right corner of the square, at the location of q, can be given as follows: e = \(k_e\)* q /\(r^2\), where \(k_e\) is the electrostatic constant, q is the charge, and r is the distance between the charge q and the upper right corner of the square.

In this expression, \(k_e\) represents the constant of proportionality, also known as Coulomb's constant, and it is equal to approximately 8.988 × \(10^9 N m^2/C^2\). The charge q represents the magnitude of the charge at the location of interest. The distance r is the distance between the charge q and the upper right corner of the square. The expression uses the inverse square law, which states that the magnitude of the electric field decreases with the square of the distance.

By plugging in the appropriate values for \(k_e\), q, and r into the expression, you can calculate the magnitude of the electric field in the upper right corner of the square.

Explanation:

The maximum acceleration of a platform is 92.7 m/s².

What is an oscillation?

Oscillation is the process of any quantity or measure repeatedly varying about its equilibrium value in time. A periodic variation of a substance between two values or around its center value is another definition of oscillation.

We know,

The acceleration amplitude = \(a_{m}\) = ω²\(x_{m}\)

Here,

ω = angular frequency (ω=2\(\pi\)f)

There are 2\(\pi\) radians in one cycle, so we obtain:

The combined momentum after the collision is M * v units, where M represents the combined mass of the putty and the bowling ball, and v represents their final velocity.

When the piece of putty moving with 1 unit of momentum strikes and sticks to the initially stationary heavy bowling ball, the law of conservation of momentum applies. According to this law, the total momentum before the collision is equal to the total momentum after the collision.

Before the collision, the momentum of the putty is 1 unit (as given), and the momentum of the bowling ball is 0 since it is initially at rest. Therefore, the total momentum before the collision is 1 + 0 = 1 unit.

After the collision, the putty sticks to the bowling ball, and they move together as a combined system. Let's assume the combined mass of the putty and the bowling ball is M, and the final velocity of the combined system is v.

The momentum of the combined system after the collision is the product of the total mass and the final velocity: M * v. Since the putty sticks to the bowling ball, the final velocity of the combined system will depend on the masses of the putty and the bowling ball and the conservation of momentum equation.

Therefore, the combined momentum after the collision is M * v units, where M represents the combined mass of the putty and the bowling ball, and v represents their final velocity.

The spring stiffness, or spring constant, of the given perfect spring is approximately 137.9623 N/m. This means that for every meter of extension, the spring will exert a force of 137.9623 N.

This value was obtained by applying Hooke's Law and calculating the ratio of the change in force to the change in extension using two data points from the table.

To determine the spring stiffness, we need to calculate the spring constant (k) using Hooke's Law, which states that the force applied on a spring is directly proportional to the extension it undergoes.

Hooke's Law can be represented as F = kx, where F is the applied force and x is the extension of the spring.

In the given table, we have the applied forces (F) and corresponding extensions (x). We can use any two data points from the table to find the spring constant.

Let's choose the first and last data points from the table:

(x1, F1) = (0.43 m, 59.34 N) and (x2, F2) = (0.96 m, 132.48 N).

Using Hooke's Law, we can calculate the spring constant (k) as follows:

k = (F2 - F1) / (x2 - x1)
  = (132.48 N - 59.34 N) / (0.96 m - 0.43 m)
  = 73.14 N / 0.53 m
  ≈ 137.9623 N/m (rounded to 4 decimal places)

Therefore, the spring stiffness, or spring constant, is approximately 137.9623 N/m.

Hooke's Law is a fundamental concept in physics that describes the relationship between the force applied on a spring and the resulting extension it undergoes.

The formula F = kx represents this relationship, where F is the applied force, k is the spring constant, and x is the extension of the spring.

By using two data points from the table, we can calculate the spring constant by finding the ratio of the change in force to the change in extension.

This calculation allows us to quantify the stiffness of the spring.

The equation of angular velocity does make sense based on correct units and dependence on time for rotating sign motion.

The proposed equation for angular velocity (ω) is:
\(ω(t) = (3g sin) / (2Ls) * t\)

where ω is angular velocity, g is acceleration due to gravity, sinº represents the sine of an angle, Ls is length scale, and t is time.

Let's examine if this equation makes physical sense:

1. Angular velocity should have units of radians per second (rad/s). In the given equation, the units of g are m/s², and the units of Ls are meters (m). The sine function is unitless. So, the units of the equation become:

(rad/s) = (\(m/s^2\) * unitless) / (m) * s

which simplifies to:

(rad/s) = (\(m/s^2\)) / (m) * s

This results in the correct units for angular velocity:

(rad/s) = 1/s

2. The equation should be dependent on time to describe the motion of a rotating sign. The given equation has a time variable, t, which means it does account for changes in the motion over time.

Considering these factors, the given equation does make physical sense. However, without additional context or information about the specific problem, it's not possible to determine whether the equation accurately models the scenario in question.

The final temperature that the steam reaches when 13553.8 kJ of heat is released is approximately 1126.8 °C.

To determine the final temperature that the steam reaches when 13553.8 kJ of heat is released, we can use the concept of heat transfer and the specific heat capacities of water and steam.

The formula for heat transfer is:

Q = m * c * ΔT

Where:

Q is the heat transferred (in kilojoules, kJ)

m is the mass of the substance (in kilograms, kg)

c is the specific heat capacity of the substance (in kilojoules per kilogram per degree Celsius, kJ/kg°C)

ΔT is the change in temperature (in degrees Celsius, °C)

We need to find the final temperature (ΔT) of the steam, so we rearrange the formula:

ΔT = Q / (m * c)

Given:

Q = 13553.8 kJ

c (specific heat of steam) = 2.010 kJ/kg°C

However, we don't have the mass (m) of the steam. To find it, we can use the heat of vaporization (L) and the equation:

Q = m * L

Given:

L (latent heat of vaporization) = 2260 kJ/kg

Let's solve for the mass (m) first:

m = Q / L

m = 13553.8 kJ / 2260 kJ/kg

m ≈ 6 kg (rounded to three decimal places)

Now we can substitute the values into the formula to find the final temperature:

ΔT = Q / (m * c)

ΔT = 13553.8 kJ / (6 kg * 2.010 kJ/kg°C)

ΔT ≈ 1126.8 °C (rounded to one decimal place)

Where:

I is the current (in Amperes),

n is the density of charge carriers,

A is the cross-sectional area of the wire,

v is the average drift velocity of electrons,

q is the charge of an electron.

In this case, we have been given current as 10A, cross-sectional area of the wire is 1mm². The density of charge carriers in the wire is 1027/m³. So, by substituting all the given identities in the equation and rearranging the equation to find out "v", we get:
