When the Azimuth is 315° and the Bearing is N45°W, what is the
Cardinal direction?

The average temperature over the past 1000 years has been about 15∘c, from the graphs, you can conclude that the earth's average temperature during the past 800,000 years has varied between about 7∘C and 19∘C.

The earth’s average temperature record illustrates the variations in ocean and atmosphere temperatures throughout a range of historical periods. Since the end of the Pleistocene glacier, many estimations of temperature have been made, especially for the current Holocene epoch. Geologic data that dates back millions of years provides some temperature information. Ice core data, which is more recent, covers the time from 800,000 years ago to the present.

Paleoclimate research spans the time from 12,000 years ago to the present. The global temperature from 1,000–2,000 years ago till the present can be determined through observations taken from ice cores and tree rings. The most thorough records date back to 1850 when meticulous thermometer-based recordings first started.

Part A: When the object is at the focal point, an infinite angular magnification is obtainable

The angular magnification obtainable with a simple magnifier is given by the equation:

M = 1 + (D/f)

where D is the least distance of distinct vision (usually taken to be 25 cm) and f is the focal length of the lens.

If the object is at the focal point, then the image formed by the lens will be at infinity. In this case, D = infinity, and the angular magnification simplifies to:

M = 1 + (∞/5.70 cm) = ∞

Therefore, when the object is at the focal point, an infinite angular magnification is obtainable.

Part B:  When the lens is used as a simple magnifier, the object should be placed at a distance of 5.70 cm or more from the lens to ensure that the image is at infinity and can be viewed comfortably by the eye.

When an object is brought close to the lens, the image formed by the lens will also be close to the lens. To ensure that the image is at infinity (so that the eye can view it comfortably), the object should be placed at the least distance of distinct vision (D).

The formula for the distance between the object and the lens is given by the lens formula:

1/f = 1/\(d_o\)+ 1/\(d_i\)

where \(d_o\) is the object distance, \(d_i\) is the image distance, and f is the focal length of the lens.

Since the image is at infinity, \(d_i\) = infinity, and the formula reduces to:

1/f = 1/\(d_o\)

Solving for \(d_o\), we get:

\(d_o\) = f = 5.70 cm

Therefore, when the lens is used as a simple magnifier, the object should be placed at a distance of 5.70 cm or more from the lens to ensure that the image is at infinity and can be viewed comfortably by the eye.

Negative 3

Explanation:

Bc scientific notation is the zeros either ahead or behind the actual numbers

Answer:

Explanation:

To make a 20.0 mL solution with a density of 0.90 g/ml, you would mix water with the substance that has the closest density to 0.90 g/ml from the materials list. In this case, the substance is dishwashing liquid with a density of 0.908 g/ml.

To make 20.0 mL of the solution, you would need to determine the mass of the dishwashing liquid to add to the water. You can use the equation for density:

density = mass/volume

Rearranging the equation to solve for mass:

mass = density * volume

Plug in the known values:

mass = 0.90 g/mL * 20.0 mL = 18.0 g

So, you would mix 18.0 g of dishwashing liquid with 20.0 mL of water to make a solution with a density of 0.90 g/mL.

The approximate vertical component of the net force that is propelling the rocket away from Earth is 112,000 N. Option B is correct.

The net force acting on the rocket is the sum of the thrust force and the weight of the rocket. The thrust force is pointing upwards at an angle of 20 degrees, and the weight of the rocket is pointing downwards. The thrust force is the force that is generated by the rocket engine. It is the force that propels the rocket upwards.

The weight of the rocket is the force of gravity acting on the rocket. It is the force that pulls the rocket downwards. The net force acting on the rocket is the sum of the thrust force and the weight of the rocket. If the net force is positive, the rocket will accelerate upwards. If the net force is negative, the rocket will accelerate downwards. If the net force is zero, the rocket will remain at rest.

net force = thrust force + weight

vertical component of net force = thrust force * cos(angle)

vertical component of net force = 700,000 N * cos(20 degrees) = 112,000 N. Option B is correct.

Answer is c, they are equal:

Explanation:

A ball is dropped from a height of 10 m. Its velocity upon impact with the ground is (v) = (a) 14 m/s.

Velocity is a term that means that the object has changed its position by making a distance in a given time. That called the velocity of the object. It can be measured in m/s, cm/s.

To calculate the velocity we are using the formula,

v²-u²=2gh

As we know the ball start velocity from rest so, u=0

v²=2gh

Or, v=√2gh

Here we are given,

h= the height of the cliff from the ball fell. = 10m.

g= The acceleration due to gravity. = 9.8 m/s².

We have to calculate the velocity of the ball = v m/s.

Now we put the values in above equation, we get

v=√2gh

Answer:

Most energy crises have been caused by localized shortages, wars and market manipulation. Some have argued that government actions like tax hikes, nationalisation of energy companies, and regulation of the energy sector, shift supply and demand of energy away from its economic equilibrium.

Standard entropy (S°) is a measure of the distribution of energy in a system. It indicates the degree of randomness or disorder of a system.

For two monatomic species, the one with the larger molar mass will have a higher standard entropy.

This statement is correct because the standard entropy of an atom is proportional to its mass.

As the molar mass increases, the degree of freedom of the atoms also increases, resulting in a higher standard entropy.

For elements with two allotropic forms, the one that is more mobile will have a greater value for standard entropy.

This statement is also correct.

The entropy of a molecule depends on its freedom of movement.

The more mobile and flexible the molecule is, the more possibilities for entropy it has.

Therefore, the correct statements regarding the general trends in standard entropy are:

For two monatomic species, the one with the larger molar mass will have a higher standard entropy.

For elements with two allotropic forms, the one that is more mobile will have a greater value for standard entropy.

Answer:

Explanation:

The panel must have a span rating of at least 48.5 to meet the deflection limit requirement and the minimum thickness of the sheathing panel for the flat roof would be 2 1/2 inches

Based on the given information, the minimum span rating and thickness of the sheathing panel for the flat roof would be:

- The total load on the roof is 8 psf (dead load) + 50 psf (snow load) = 58 psf. - The deflection limit for the snow load is L/240, where L is the span of the joists.

Therefore, L = 240 x deflection limit / snow load = 240 x (1/240) / 50 = 0.0048 feet or 0.0576 inches.

- The deflection limit for the total load is L/180, which is more restrictive than the snow load deflection limit.

Therefore, we need to use L/180 as the deflection limit for the span rating and thickness calculation.

- The minimum required span rating for the sheathing panel can be calculated as follows:

Span rating = (1.15 x snow load x span^2) / (deflection limit x panel width) where panel width is 4 feet for APA rated sheathing panels.

Substituting the values, we get:

Span rating = (1.15 x 50 x 0.0576^2) / (0.00333 x 4) = 48.5

The minimum span rating for the sheathing panel is 48.5. This means that the panel must have a span rating of at least 48.5 to meet the deflection limit requirement.

- The minimum required thickness of the sheathing panel can be determined from the span rating and panel span as follows:

Thickness = span rating / 20 where span rating is in inches.

Substituting the values, we get:

Thickness = 48.5 / 20 = 2.425 inches or approximately 2 1/2 inches.

Therefore, the minimum thickness of the sheathing panel for the flat roof would be 2 1/2 inches

Explanation:

When a free positive charge q is accelerated by an electric field, such as shown in Figure 1, it is given kinetic energy. The process is analogous to an object being accelerated by a gravitational field. It is as if the charge is going down an electrical hill where its electric potential energy is converted to kinetic energy. Let us explore the work done on a charge q by the electric field in this process, so that we may develop a definition of electric potential energy.

The electrostatic or Coulomb force is conservative, which means that the work done on q is independent of the path taken. This is exactly analogous to the gravitational force in the absence of dissipative forces such as friction. When a force is conservative, it is possible to define a potential energy associated with the force, and it is usually easier to deal with the potential energy (because it depends only on position) than to calculate the work directly.

Answer:

Oh for number this is the one?

To make the total load seen by the generator purely resistive, the reactive component of the load must be canceled out. This can be achieved by adding a reactance with the opposite sign and equal magnitude to that of the reactive component of the load.

Let's assume that the load has a resistance R and a reactance X. The total impedance of the load is then given by Z = R + jX, where j is the imaginary unit.

To cancel out the reactive component of the load, we need to add a reactance -X in series with the load, which gives a total impedance of Z' = R + jX - jX = R. This means that the total load seen by the generator is purely resistive, with no reactive component.

Therefore, to find the value of reactance Qx that needs to be added, we just need to find the magnitude of the reactive component of the load, which is |X|. So, Qx = |X|.

Answer: 20m/s.

Explanation:

Remember the second Newton's law:

F = a*m

This is:

The net force acting on an object is equal to the mass of the object times the acceleration of the object.

In this case, we have a force of 5N pushing the object to the right.

We also have a force of 5N pushing the object to the left.

These forces act on opposite directions.

Then the net force will be equal to the difference of these forces, this is:

F = 5N - 5N = 0N

Then the net force is 0N, then we have:

0N = m*a

0N/m = 0m/s^2 = a

This means that the acceleration of the object is 0, then the velocity of the object does not change.

This means that if the object was moving at a constant velocity of 20m/s, the velocity of the object will still be equal to 20m/s. (because the net force acting on the object is zero)

When a brick with dimensions of 20cm x 15cm x 10cm and a mass of 2 kg is placed on a surface, the orientation of the brick can affect how it is supported by the surface.

If the brick is placed along its length and breadth, then the surface area that is in contact with the surface is 20cm x 15cm = 300cm². This means that the weight of the brick is distributed over this area, which results in a pressure of approximately 6.67 kPa. On the other hand, if the brick is placed along its breadth and height, then the surface area that is in contact with the surface is 15cm x 10cm = 150cm². This means that the weight of the brick is distributed over this smaller area, which results in a higher pressure of approximately 13.33 kPa. It is important to note that the surface area in contact with the surface is not the only factor that affects the pressure exerted by the brick. The load distribution within the brick can also play a role in the pressure exerted on the surface. In summary, the orientation of the brick can affect how it is supported by the surface and the pressure it exerts. When placing a heavy object on a surface, it is important to consider the load distribution and choose the orientation that will distribute the weight evenly for the best support and safety.
