The thickness of the air column above 1 m² of the Earth's surface that would have a weight of about 100,000 N is equal to 8,680.56 meters assuming the density of air remained constant at 1.2 kg/m³.

If the density of air were a constant 1.2 kg/m³ throughout the atmosphere, we can calculate the thickness of the air column that would have a weight of about 100,000 N on an area of 1 m².

The weight of the air column can be calculated using the formula:

Weight = density × volume × gravitational acceleration

We can rearrange the formula to solve for the volume:

\(\text{{Volume}} = \frac{{\text{{Weight}}}}{{\text{{density}} \times \text{{gravitational acceleration}}}}\)

Substituting the given values:

Weight = 100,000 N

Density = 1.2 kg/m³

Gravitational acceleration (g) ≈ 9.8 m/s²

\(Volume = \frac{100000 N}{(1.2 kg/m^3) \times (9.8 m/s^2)}\)

Volume ≈ 8,680.56 m³

Therefore, if the density of air were a constant 1.2 kg/m³, the thickness of the air column above 1 m² of the Earth's surface that would have a weight of about 100,000 N is approximately 8,680.56 meters.

The ratio of the mass density of girder a to the mass density of girder b is 1/2.

It is possible to measure a materials density by how closely it is packed. The mass per unit volume is how it is formally defined. The density is expressed as follows: = m/V, where m is the object's mass and V is its volume.

A material substance's density is defined as its mass per unit volume. D is density, M is mass, and V is volume, and the formula for density is d = M/V. Most often, grammes per cubic centimetre are used to express density.

Since they are made of same material, their mass density is same. Their mass is different but not mass density.

The airline will need to have at least 167 passengers on each flight to break even.

To calculate the number of passengers needed to break even, we need to consider the total costs and the revenue generated per flight.

The total cost per flight consists of the fixed costs (£25,000) and the variable costs (£75 per passenger). The revenue per flight is determined by the ticket price (£225) multiplied by the number of passengers.

Let's denote the number of passengers as 'P'. The total cost per flight is given by:

Total Cost = Fixed Costs + (Variable Cost per Passenger * Number of Passengers)

Total Cost = £25,000 + (£75 * P)

The revenue per flight is given by:

Revenue = Ticket Price * Number of Passengers

Revenue = £225 * P

To break even, the total cost should equal the revenue:

£25,000 + (£75 * P) = £225 * P

Now, we can solve this equation for P to find the number of passengers needed to break even:

£25,000 + (£75 * P) = £225 * P

£25,000 = £225 * P - £75 * P

£25,000 = £150 * P

P = £25,000 / £150

P ≈ 166.67

Since the number of passengers must be a whole number, we round up to the nearest whole number:

P = 167

The airline will need at least 167 passengers on each flight to break even. However, since the maximum capacity of the aircraft is 200 passengers, the airline will need to fill the aircraft to its maximum capacity to break even on each flight.

Explanation:

μ = coefficient of friction.

F = Frictional force = 12N

R = Normal reaction = mg = Weight = 240N

The Weight of an object is more at pole and less at equator of the earth because the distance of the pole is less than the distance of the equator from the centre of the earth.

Answer:

height = 1.5 x 10⁶ m = 1500 km

Explanation:

We can use the formula of gravitational force from the Newton's Gravitational Law:

\(F = \frac{Gm_{1}m_{2}}{r^2}\)

where,

F = Gravitational Force = 6.6 x 10³ N

G = Universal Gravitational Constant = 6.67 x 10⁻¹¹ N.m²/kg²

m₁ = mass of earth = 6 x 10²⁴ kg

m₂ = mass of satellite = (1.02 tons)(1000 kg/1 ton) = 1.02 x 10³ kg

r = distance between center of earth and satellite = ?

Therefore, using these values in the equation, we get:

\(6.6\ x\ 10^3\ N = \frac{(6.67\ x\ 10^{-11} N.m^2/kg^2)(6\ x\ 10^{24} kg)(1.02\ x\ 10^3\ kg)}{r^2}\\\\r^2 = \frac{(6.67\ x\ 10^{-11} N.m^2/kg^2)(6\ x\ 10^{24} kg)(1.02\ x\ 10^3\ kg)}{6.6\ x\ 10^3\ N}\\\\\)

\(r = \sqrt{61.84\ x\ 10^{12}\ m^2 }\)

\(r = 7.86\ x\ 10^6 m\)

The distance between center of earth and the satellite is equal to the sum of height of satellite and radius of earth:

\(r = height + radius\ of\ earth\\7.86\ x\ 10^6 m = height + 6.36\ x\ 10^6 m\\height = 7.86\ x\ 10^6 m - 6.36\ x\ 10^6 m\)

height = 1.5 x 10⁶ m = 1500 km

Answer:

The total frictional force equals 60 N

Explanation:

We know that F - f = ma where F is the applied force, f is the frictional force, m the mass of the object and a its acceleration.

Now, since the cart moves with constant velocity, its acceleration is zero. So, a = 0.

So F - f = ma

F - f = m(0) = 0

F - f = 0

So, F = f

From the above, we see that the frictional force equals the applied force which is equal to 60 N.

So, f the total frictional force equals 60 N

Explanation:

The mutual inductance between the coils is 6.25μH. the coefficient of coupling between the coils is approximately 0.447.

The mutual inductance between the coils can be determined using the formula:M = (Δφ_Y) / (N_X * ΔI_X)
Where M represents the mutual inductance, Δφ_Y is the change in flux in coil Y, N_X is the number of turns in coil X, and ΔI_X is the change in current in coil X.
Plugging in the values given, we have: M = (5mWb) / (200 * 4A)

M = 5mWb / 800A

M = 6.25μH. Therefore, the mutual inductance between the coils is 6.25μH.

(b) The coefficient of coupling (k) can be calculated using the formula:

k = M / √(L_X * L_Y)

Where k represents the coefficient of coupling, M is the mutual inductance, L_X is the self-inductance of coil X, and L_Y is the self-inductance of coil Y.
Substituting the given values: k = (6.25μH) / √((80mH) * (60mH))

k = 6.25μH / √(4.8mH^2)

k ≈ 0.447. Therefore, the coefficient of coupling between the coils is approximately 0.447.

Answer:

Please feel free to edit this:

A lunar eclipse can be photographed sometimes when Earth is in between the sun and the moon.

A lunar eclipse is when Earth prevents sunlight from reaching the moon (when the moon passes through Earth's shadow). There are (at least) two reasons that a lunar eclipse cannot be photographed every time the Earth is between the Sun and the moon. One concerns the shadow(s) and the other concerns the orbit of the moon around Earth.  A lunar eclipse occurs when the earth's shadow falls on the moon. For this to happen, the earth has to be between the sun and the moon. During a total eclipse, the sun, earth, and moon are perfectly lined up, and the only light hitting the moon is what is scattered by the edges of our atmosphere. It is mostly red light that makes it through, which is why during a total lunar eclipse, the moon appears red. During a partial eclipse, the earth is still between the sun and moon, but they are not perfectly lined up, so only part of the moon is in shadow.

Here's my message to Eric Wu telling him when a lunar eclipse can be photographed:

A lunar eclipse can occur only at full moon. A total lunar eclipse can happen only when the sun, earth and moon are perfectly lined up anything less than perfection creates a partial lunar eclipse or no eclipse at all. And you can only photographed Lunar Eclipse when the Moon passes through the Earth's shadow, just as a solar eclipse occurs when part of the Earth passes through the Moon's shadow. First, regarding shadows. There are three "types" of shadow cast by Earth called the Umbra, Penumbra, and Antumbra. The umbra is the darkest part of the shadow and is where all illuminate from the Sun is blocked by Earth. The penumbra is the lighter outer part of the shadow where only a portion of the Sun is covered. The Antumbra is another lighter shadow which occurs where Earth appears smaller than the Sun so that the edges of the Sun can be seen as a ring around Earth. The Antumbra occurs at large distances from Earth. In Earth or Moon lunar eclipses, only the umbra and penumbra are important because the antumbra begins outside of the moon's orbit.

Lunar eclipses involving the umbra are readily apparent because the moon becomes nearly invisible. These eclipses are called total and partial lunar eclipses (depending on how much of the moon passes through the umbra.) Eclipses where the moon passes through Earth's penumbra (accordingly designated "penumbral lunar eclipses" ) produce only a slight darkening of the moon. Thus, while penumbral lunar eclipses are still eclipses, the shadowing is so subtle that they can be difficult to see and photograph. Now, regarding the moon's orbit and the sun, moon & Earth arrangement. At every full moon, Earth is essentially between the Sun and the moon. But lunar eclipses do not occur at every full moon (and analogously, solar eclipses do not occur at every new moon). This is because the plane in which the moon orbits Earth is not the same as the plane in which Earth orbits the Sun (called the ecliptic). Instead, the moon's orbit is inclined at ~5° from the ecliptic. As the moon orbits Earth, it changes between being above and below the ecliptic, necessarily crossing the ecliptic twice per lunar cycle (i.e., full moon-to-full moon cycle). This means that the moon is only in the same plane as the Sun and Earth twice per orbital revolution and thus there are only two times per cycle for which the Sun, Earth, and the moon are all in the same plane. But they may not be on the same line, the moon also must be in the "full" position, otherwise Earth will not be between it and the Sun. The timing of full and new moons do not always align with that of the moon reaching the crossing points called "nodes" because the time for the moon to complete a cycle of phases (29.5 days) is slightly different from the time to complete one orbit of Earth (27.3 days).

These are the most common allergens during this time that leads to sneezing and suffering from allergic reactions. Pollens are too heavy to be airborne for a longer time or they are inhaled from the air and lead to allergic reactions.

Lamar's average velocity is 1 m/s

We know that,

Average Velocity = Total distance travelled / Total time taken

Given that,

Distance travelled west = 20 m

Distance travelled East = 20 m

Total time taken = 40 s

Total distance travelled = 20 + 20 = 40 m

Average Velocity = 40 / 40 = 1 m/s

Average velocity is total rate of change of displacement.

Explanation:

The units of pressure is called derived units because it is simply derived from base unit which is distance and a derived unit which is force, which is derived from acceleration, a derived unit as well, and mass, a base unit. As we all know, work is defined as the force x distance. Thus making work a derived unit.

To calculate the divergence of a vector field, in this case, the gravitational force field F, we need to take the dot product of the gradient (∇) operator with the vector field. In Cartesian coordinates, the divergence (∇ ·) of a vector field F = Fx i + Fy j + Fz k can be calculated as follows:

∇ · F = (∂Fx/∂x) + (∂Fy/∂y) + (∂Fz/∂z)

F = Gp²

To calculate the divergence, we need to find the partial derivatives of each component of F with respect to its corresponding coordinate. In this case, p = (px, py, pz), and each component is squared:

Fx = G(px)²

Fy = G(py)²

Fz = G(pz)²

∂Fx/∂x = 2Gpx

∂Fy/∂y = 2Gpy

∂Fz/∂z = 2Gpz

∇ · F = (∂Fx/∂x) + (∂Fy/∂y) + (∂Fz/∂z)

= 2Gpx + 2Gpy + 2Gpz

= 2G(px + py + pz)

Therefore, the divergence of the gravitational force field F is 2G times the sum of the components of the vector p, which is (px + py + pz).
