Camille is driving her boat down the coast to the East (90 deg) at a steady 20 meters/sec. Her raft is
being pushed by a 3 meter/sec current to the South. After 5 minutes, what is her displacement from her
original position?
Answers
The displacement is 900 meter current to the South.
What is the displacement?We know that velocity is the ratio of the displacement of a body to time. Displacement is a vector quantity just as velocity. We know that given the fact that velocity and displacement are vectors, the direction of the movement is very important.
Thus, we can see that;
Velocity = 3 meter/sec current to the South
Time = 5 minutes or 300 sec
Velocity = displacement/ time
displacement = velocity * time
displacement = 3 meter/sec current to the South * 300 sec
= 900 meter current to the South

in some mountain belts the crust breaks into fault-bounded blocks resulting in ____ mountain ranges
Answers
In some mountain belts, the crust breaks into fault-bounded blocks resulting in block mountain ranges. This type of mountain range is also referred to as a horst and graben terrain.
A horst is the raised block of land that is bordered by two parallel faults while a graben is the sunken block of land that is bordered by two parallel faults. The faulting occurs due to tectonic plate movements and can lead to the formation of steep-sided mountain ranges.
Block mountain ranges are common in regions where there is a lot of tensional stress in the Earth's crust. The tensional stress causes the rocks to crack and break along fault lines. Over time, the blocks of land between the faults can be lifted upwards, creating a horst, or lowered downwards, creating a graben. The movement along the faults can also create earthquakes.
Block mountain ranges can be found in many parts of the world, including the Rocky Mountains in North America and the Atlas Mountains in North Africa. They are often associated with volcanic activity and can be important sources of mineral resources. In addition, these mountains can create unique habitats for plants and animals that are adapted to the challenging environments created by the steep slopes and variable climates.

what observations about disks of dusty material around young stars suggest that planets may be forming in such disks?
Answers
Planets may be forming from dust disks because these disks are filled with completely empty lanes.
We can arrive at this answer because:
The existence of empty lanes allows the dust disks to transform into many different materials, including new planets.In this case, there is a cooling of the dust disk, which cools more and more over time.This cooling causes all the particles in that disk to clot.Coagulation increases the density of the particles and if they are dense enough they can form escape accretions.Escape accretions allow for the formation of planetary embryos, which may form planets in the future.

where should the paper be placed relative to the lens to get a sharp image? express your answer with the appropriate units.
Answers
The paper should be placed at the focal point of the lens to obtain a sharp image.
The focal point of a lens is the point where parallel rays of light converge or diverge after passing through the lens. Placing the paper at this point ensures that the incoming light rays from the object on the other side of the lens converge precisely onto the paper, resulting in a focused and sharp image.
The distance between the lens and the paper should be equal to the focal length of the lens. The unit of focal length is typically measured in millimeters (mm) or meters (m), depending on the scale of the lens. Therefore, the paper should be positioned at the focal point of the lens to achieve a sharp image, with the distance measured in units of length such as millimeters or meters.

14. 12 The timber box section (a) of Problem 14. 29 is used as a simply supported beam on an 18-ft span length. The beam carries a uniformly distributed load of 500 lb/ft, which includes its own weight. Calculate the maximum induced to bending stress
Answers
The maximum induced bending stress in the timber box section (a) of Problem 14.29, when used as a simply supported beam on an 18-ft span length carrying a uniformly distributed load of 500 lb/ft, is approximately 433 psi.
Mmax = (wL²)/8
where w is the uniformly distributed load, L is the span length, and Mmax is the maximum bending moment.
In this case, w = 500 lb/ft and L = 18 ft. Substituting these values into the formula, we get:
Mmax = (500 lb/ft)(18 ft)² / 8 = 22,500 lb-ft
Now, to calculate the maximum bending stress, we use the bending stress formula:
σmax = Mmax * y / I
For the timber box section (a), the moment of inertia can be calculated as:
I = 2[(1/12)(b)(h³) + (1/12)(h)(b³)]
where b is the width of the section and h is the height.
Substituting the values of b = 6 inches and h = 8 inches, we get:
I = 2[(1/12)(6 in)(8 in)³ + (1/12)(8 in)(6 in)³³] = 208 \(in^4\)
The distance y from the neutral axis to the outermost fiber can be taken as half the height of the section, i.e., y = 4 inches.
Substituting the values of Mmax, y, and I into the bending stress formula, we get:
σmax = (22,500 lb-ft) * (4 in) / 208 \(in^4\) = 432.7 psi
Bending stress is a type of mechanical stress that occurs in a beam or any other structural element when it is subjected to a load or force that causes it to bend. This stress arises as a result of the internal forces that develop in the material due to the applied load, which causes the beam to deform or bend.
When a beam is subjected to a bending load, the top surface is compressed, and the bottom surface is stretched. The stress at any point on the cross-section of the beam varies linearly from zero at the neutral axis to a maximum value at the extreme fiber.The maximum bending stress that a beam can withstand before it fails is known as the yield strength of the material. The bending stress can be calculated using the formula M*y/I, where M is the bending moment, y is the distance from the neutral axis to the extreme fiber, and I is the second moment of area of the cross-section of the beam.

B. It is 100 m/s2 downward.
C. It is 3 m/s2 upward.
D. It is 3 m/s2 downward.
Answers
Answer:
It is 3 m/s² downward.
Explanation:
The mass of an object, m = 30 kg
Upward force, F = 200 N
Downward force, F' = -300 N
We need to find the magnitude and direction of its acceleration.
Net force = F+F'
= 200+(-300)
= -100 N
We know that,
Force, F = ma, a is acceleration of the object
\(a=\dfrac{F}{m}\\\\a=\dfrac{-100}{30}\\\\a=-3.33\ m/s^2\approx -3\ m/s^2\)
Hence, the acceleration is -3 m/s² and it is acting in the downward direction.
We can roughly model a gymnastic tumbler as a uniform solid cylinder of mass 75 kg and diameter 1.0 m. If the tumbler rolls forward at .50 rev/s.A) how much total kinetic energy does he have? B) what percent of his total kinetic energy is rotational?
Answers
The gymnastic tumbler has a total kinetic energy of 0.9375 J, and 38.46% of that total kinetic energy is due to rotational motion.
What is kinetic energy?
Kinetic energy is the energy possessed by an object due to its motion. It is defined as the work required to accelerate an object of a certain mass from rest to its current velocity.
Given:
Mass of the tumbler (m) = 75 kg
Diameter of the tumbler (d) = 1.0 m
Angular velocity (ω) = 0.50 rev/s
The radius (r) of the tumbler is half of its diameter, so r = d/2 = 0.5 m.
Linear velocity (v) = ω * r
v = (0.50 rev/s) * (0.5 m)
v = 0.25 m/s
a) Total kinetic energy (K_total) of the tumbler consists of both translational and rotational kinetic energy. The translational kinetic energy (K_trans) can be calculated using the formula:
K_trans = (1/2) * m * v^2
K_trans = (1/2) * (75 kg) * (0.25 m/s)^2
K_trans = 0.9375 J
b) The rotational kinetic energy (K_rot) can be calculated using the formula:
K_rot = (1/2) * I * ω^2
I = (1/2) * m * r^2
I = (1/2) * (75 kg) * (0.5 m)^2
I = 4.6875 kg·m²
K_rot = (1/2) * (4.6875 kg·m²) * (0.50 rev/s)^2
K_rot = 0.5859 J
Percentage of rotational kinetic energy = (K_rot / K_total) * 100
Percentage of rotational kinetic energy = (0.5859 J / (0.9375 J + 0.5859 J)) * 100
Percentage of rotational kinetic energy ≈ 38.46%
Therefore, the gymnastic tumbler has a total kinetic energy of approximately 0.9375 J, and approximately 38.46% of that total kinetic energy is due to rotational motion.

An object with a charge of -3C is touched to an object with a charge of -1C. What is the new charge on each object?
Answers
After connecting the conducting wire, the spheres will redistribute charges until they both have a charge of -1C.
To determine the new charges on the spheres, we need to consider the principle of charge conservation, which states that the total charge before and after an interaction remains the same.
Let's assume that the spheres have charges Q1 and Q2 initially. In this case, Q1 = -3C and Q2 = +1C.
When a conducting wire is connected between the spheres, charge can redistribute until the system reaches equilibrium. Since the spheres are conducting, charges are free to move within them.
In the final state, the charges on the spheres will redistribute to reach a new equilibrium. Let's assume the new charges on the spheres are Q1' and Q2'.
According to the principle of charge conservation, the total charge before and after the connection remains the same:
Initial total charge = Q1 + Q2 = -3C + 1C = -2C
Final total charge = Q1' + Q2'
Since the total charge remains the same, we can write the equation:
Q1' + Q2' = -2C
Since the spheres are of equal size, we can assume that the charges redistribute equally:
Q1' = -1C
Q2' = -1C

Answers
Answer:
\(t = 0.75 \ hr = 0.75 *60 = 45 \ minutes\)
Explanation:
From the question we are told that
The hydraulic conductivity is \(Ks = 10\ mm/hr\)
The effective matrix potential \(Ns = 20 \ mm\)
The intensity of rainfall is \(I = 30 \ mm/hr\)
The runoff rate \(R = 15 \ mm/hr\)
Generally the run off rate is mathematically represented as
\(R = (I - Ks) t\)
Here t is the amount of runoff generated

converting to minutes
\(t = 0.75 \ hr = 0.75 *60 = 45 \ minutes\)
Consider a telescope with a small circular aperture of diameter 2.0 centimeters.Calculate the angular separation θ1 at which two point sources of wavelength 600 nanometers are just resolved when viewed through a circular aperture of diameter 1.5 centimeters. Express your answer in radians to three significant figures.
Answers
The angular separation θ1 at which two point sources of wavelength 600 nanometers viewed through a circular aperture of diameter 1.5 centimeters are just resolved can be calculated using the formula θ1 = 1.22λ/D, where λ is the wavelength of light and D is the diameter of the aperture. In this case, θ1 = 0.00197 radians, which is equivalent to 1.13°.
The angular resolution of a telescope determines the level of detail that can be seen in an image. A higher angular resolution will allow for finer details to be seen, while a lower angular resolution will make it more difficult to distinguish between objects. In this case, the angular resolution is 0.00197 radians, which is quite high and should allow for two point sources of light of wavelength 600 nanometers to be just resolved when viewed through a circular aperture of diameter 1.5 centimeters.
