5.66 seconds after it is thrown, the position of the rock is approximately 157.266 meters below the initial position at the edge of the cliff.

To calculate the position of the rock 5.66 seconds after it is thrown, we can use the equations of motion.

First, let's break down the problem into two parts: the upward motion and the downward motion of the rock.

1. Upward motion:

During the upward motion, the acceleration due to gravity acts in the opposite direction of the initial velocity. We can use the equation of motion for displacement:

s₁ = u₁t + (1/2)at²

where s₁ is the displacement, u₁ is the initial velocity, t is the time, and a is the acceleration.

Since the rock is thrown straight up, the initial velocity u₁ is 24.8 m/s, the acceleration a is -9.8 m/s² (taking it as negative due to the opposite direction), and the time t is 5.66 seconds.

Plugging in the values:

s₁ = (24.8 m/s)(5.66 s) + (1/2)(-9.8 m/s²)(5.66 s)²

s₁ = 140.448 m + (-78.633 m)

s₁ = 61.815 m

2. Downward motion:

During the downward motion, the rock is in free fall, so we can use the equation for displacement again:

s₂ = u₂t + (1/2)at²

where s₂ is the displacement, u₂ is the final velocity (which is the negative of the initial velocity due to the change in direction), a is the acceleration due to gravity (taking it as -9.8 m/s²), and t is the time.

Since the rock starts from rest at its highest point during the upward motion, the final velocity u₂ is -24.8 m/s.

Plugging in the values:

s₂ = (-24.8 m/s)(5.66 s) + (1/2)(-9.8 m/s²)(5.66 s)²

s₂ = -140.448 m + (-78.633 m)

s₂ = -219.081 m

To find the total displacement, we sum the upward and downward displacements:

s_total = s₁ + s₂

s_total = 61.815 m + (-219.081 m)

s_total = -157.266 m

Therefore, 5.66 seconds after it is thrown, the position of the rock is approximately 157.266 meters below the initial position at the edge of the cliff.

The resultant of two displacement vectors having opposite directions is the difference of the two displacements, having the same direction as the smaller vector.

When two displacement vectors have opposite directions, it means they are pointing in opposite ways. In other words, one vector is in the opposite direction of the other. To find the resultant of these vectors, we need to subtract one vector from the other.

If we consider two displacement vectors, let's say vector A and vector B, and they have opposite directions, we can represent them as A and -B.

To find the resultant, we subtract vector B from vector A: A - (-B) or A + B.

The resultant will have the same direction as the smaller vector. This is because when we subtract a larger vector from a smaller vector, the resultant will have the direction of the smaller vector.

Therefore, the correct option is: "The resultant is the difference of the two displacements, having the same direction as the smaller vector."

Answer:

The value of the inductance is 4.75 H

Explanation:

Given;

initial current through the inductor, I₁ = 2.4 A

final current through the inductor, I₂ = 0.3 A

duration of change of current, dt = 1.75 s

voltage change of the inductor, V = 5.7 Volts

The voltage change of the inductor is given by;

\(V_L = -L\frac{di}{dt}\\\\ V_L = -L(\frac{I_2-I_1}{dt} )\\\\V_L = L(\frac{I_1-I_2}{dt} )\\\\\)

Where;

L is the inductance of the coil;

\(5.7 = L(\frac{2.4-0.3}{1.75} )\\\\5.7 = 1.2 L\\\\L = \frac{5.7}{1.2}\\\\ L = 4.75 \ H\)

Therefore, the value of the inductance is 4.75 H

Based on the information, it should be noted that the resistance R is 0.5 Ω.

When S1 and S2 are open, i leads e by 30°. In this case, the circuit consists of only the inductor (L) and the capacitor (C) in series. Therefore, the impedance of the circuit can be written as:

Z = jωL - 1/(jωC)

Since i leads e by 30°, we can express the phasor relationship as:

I = k * e^(j(ωt + θ))

Z = jωL - 1/(jωC) = j(120π)L - 1/(j(120π)C)

Re(Z) = 0

By equating the real parts, we get:

0 = 0 - 1/(120πC)

Let's assume that there is a resistance (R) in series with the inductor and capacitor. The impedance equation becomes:

Z = R + jωL - 1/(jωC)

Z = R + jωL

Im(Z) = ωL > 0

Substituting the angular frequency and rearranging the inequality, we have:

120πL > 0

L > 0

This condition implies that the inductance L must be greater than zero.

When S1 and S2 are closed, i has an amplitude of 0.5 A. In this case, the impedance is:

Z = R + jωL - 1/(jωC)

Since the amplitude of i is given as 0.5 A, we can express the phasor relationship as:

I = 0.5 * e^(j(ωt + θ))

By substituting this phasor relationship into the impedance equation, we can determine the value of R. The real part of the impedance must be equal to R:

Re(Z) = R

Since the amplitude of i is 0.5 A, the real part of the impedance must be equal to 0.5 A: 0.5 = R

Therefore, the resistance R is 0.5 Ω.

Answer:

To calculate the work done by a force, we can use the formula:

Work = ∫F dx

In this case, the force is given by Fx = (2x + 7) N, and the particle moves along the X-axis from X1 = 1 m to X2 = 5 m. Let's calculate the work done.

Work = ∫(2x + 7) dx

Integrating the function (2x + 7) with respect to x, we get:

Work = (x^2 + 7x) evaluated from X1 to X2

Plugging in the values X2 = 5 and X1 = 1 into the expression, we have:

Work = (5^2 + 7 * 5) - (1^2 + 7 * 1)

= (25 + 35) - (1 + 7)

= 60 - 8

= 52

Therefore, the work done by the force is 52 Joules (J).

Explanation:

The pressure applied by the man to the ground is 551812.5 Pa or 5.06 psi.

Force applied per unit area is what is referred to as pressure. It can be calculated mathematically using P=FA, where F is the force acting perpendicular to surface area A. The pascal (Pa), or one newton per square metre (N/m 2), is the common unit of pressure.

The following formula can be used to determine how much pressure the man is exerting on the ground:

Pressure = Force / Area

where Area is the portion of the stilts that are in touch with the ground and Force is the man's weight.

Weight equals mass multiplied by gravitational acceleration yields the man's weight.

Weight = 90 kg * 9.81 m/s²

Weight = 882.9 N

The area of each stilt is:

Area = length * width

Area = 0.04 m * 0.04 m

Area = 0.0016 m²

As a result, the man is exerting the following pressure on the ground:

Pressure = Force / Area

Pressure = 882.9 N / 0.0016 m²

Pressure = 551812.5 Pa

The one that is accurate is that when the phosphate is broken down into ADP, ATP releases energy.

The energy that cells need is produced through the breakdown of glucose. More energy cannot be stored by ATP molecules than is released by the cells. In actuality, ATP doesn't retain as much energy as a glucose molecule. See the equation in the question; roughly 38 ATP molecules are produced for every glucose molecule.

The cell stores extra energy by reattaching a free phosphate molecule to ADP, converting it back into ATP. This extra energy can come from the breakdown of food that has been ingested or, in the case of plants, energy produced during photosynthesis.

The given statement "static electricity is caused by moving electrical charges" is false.

Static electricity is not caused by moving electrical charges but by stationary charges. When an object builds up a static electric charge, it has an excess of electrons or a deficiency of electrons.

The charge is stationary and does not move through the object like in a current.The imbalance of charge occurs when there is friction between two surfaces, which can be two objects or an object and the ground. Electrons move from one object to the other, creating a static electric charge on each object.

The amount of charge depends on the types of materials involved, the humidity, temperature, and other factors.Static electricity can be dangerous and cause damage to electrical equipment.

To prevent static electricity, grounding is used. Grounding provides a safe and efficient path for the charge to move through and prevents the buildup of charge on the object.

Static electricity can also be used for useful purposes. Photocopiers and printers use static electricity to transfer ink to paper, and air filters use static electricity to attract and trap pollutants. In industry, static electricity is used to attract and hold materials during the manufacturing process.

Answer:

a)40 meters

b)2 m/s

c)2 m/s

d)0 m/s

e)45 degrees northeast

Explanation:

a) The displacement from C to A is the distance directly across the river, which is 40 meters.

b) The speed of the boat as seen by people standing at A is the magnitude of the boat's velocity vector, which is equal to the displacement divided by the time taken:

Speed = displacement / time = 40 m / 20 s = 2 m/s.

c) Let v be the speed of the water in the river. The boat is moving at right angles to the flow of the river, so the water exerts a perpendicular force on the boat. The time taken for the boat to travel from A to C is 20 seconds, during which time the boat will have been carried downstream by the river by a distance equal to v times the time taken.

Distance carried downstream = v × time = v × 20 m.

Since the boat landed at C, which is directly across the river from A, the distance it traveled horizontally is 40 meters. Therefore:

40 m = (boat speed) × (time taken) = (boat speed) × 20 s.

Hence, the speed of the boat is:

Boat speed = 40 m / 20 s = 2 m/s.

So, we have two equations:

Distance carried downstream = v × 20 m

Boat speed = 2 m/s

From the first equation, we get:

v × 20 m = 40 m

Therefore, the speed of the water in the river is:

v = 40 m / 20 m = 2 m/s.

d) The speed of the boat as seen by a fish drifting with the river is the difference between the speed of the boat and the speed of the water in the river:

Boat speed - Water speed = 2 m/s - 2 m/s = 0 m/s.

So, the speed of the boat as seen by a fish drifting with the river is zero.

e) The boat should head in a direction that makes its velocity vector point directly from A to B. Since A and B are directly opposite each other, this means the velocity vector should be perpendicular to the line connecting A and B.

We know the boat's velocity vector has a magnitude of 2 m/s and is at right angles to the velocity vector of the water in the river, which has a magnitude of 2 m/s. So, we can draw a vector diagram with the velocity vector of the boat pointing straight up and the velocity vector of the water pointing straight to the right. The vector connecting the tail of the water velocity vector to the head of the boat velocity vector will then point directly from A to B.

The angle between the boat's velocity vector and the line connecting A and B can be found using trigonometry. Let θ be this angle. Then:

tan(θ) = (boat speed) / (water speed) = 2 m/s / 2 m/s = 1.

Taking the inverse tangent of both sides gives:

θ = tan^(-1)(1) = 45°.

So, the boat should head in a direction 45 degrees to the right of straight up, or northeast.

a) The mass of the water displaced by the boat = 149.3 kg

b) The weight of the boat = 1463.14 N

Volume of water displaced, V = 6.7 m³

The density of water, ρ = 1000 kg/m³

The mass of the water displaced by the boat = m

The relationship between density, mass, and volume is:

ρ = mv

Substitute ρ = 1000, and V = 6.7 into the equation above, and solve for m

ρ = mV

1000 = m x 6.7

m = 1000/6.7

m = 149.3 kg

The mass of the water displaced by the boat = 149.3 kg

B) The weight, W, is calculated as:

W = mg

Substitute m = 149.3kg and g = 9.8 m/s^2 into the formula:

W = 149.3 x 9.8

W = 1463.14 N

The weight of the boat = 1463.14 N
