Answer:

Air kerma

Explanation:

The acronym for the word 'kerma' is \($\text{"kinetic energy released per unit mass"}$\). It is the sum or the total of the kinetic energies of the \($\text{charged particles}$\) that is liberated by the uncharged ionizing radiation in the small sample of a matter, and is divided by the mass of that sample.

It is sometimes used for expressing the radiation concentration that is delivered to a point.

It is used to specify the intensity of the x-rays for any given point in the air at some known distance form the local spot. The total air kerma can be monitored in the fluoroscopic procedure.

The torque experienced by a small bar magnet can be calculated using the equation τ = m × B × sinθ, where τ is the torque, m is the magnetic moment of the magnet, B is the magnetic field, and θ is the angle between the magnet's axis and the magnetic field. In this case, we know that the torque is 2.50×10−2 n⋅m, the magnetic field is 9.00×10−2 t, and the angle between the magnet's axis and the magnetic field is 45.0∘. We can solve for the magnetic moment of the magnet by rearranging the equation: m = τ / (B × sinθ). Plugging in the values, we get m = (2.50×10−2 n⋅m) / (9.00×10−2 t × sin45.0∘) = 3.54×10−2 A⋅m². Therefore, the magnetic moment of the small bar magnet is 3.54×10−2 A⋅m².

To solve this problem, we can use the formula for torque (τ) in a magnetic field:

τ = μ * B * sinθ

where τ is the torque (2.50 × 10^(-2) N⋅m), μ is the magnetic moment of the bar magnet, B is the magnetic field strength (9.00 × 10^(-2) T), and θ is the angle between the magnetic moment and the magnetic field (45.0°).

We want to find the magnetic moment μ. First, convert the angle to radians:

θ_rad = (45.0°) * (π / 180) = π / 4 radians

Now, rearrange the formula to solve for μ:

μ = τ / (B * sinθ_rad)

Plug in the values:

μ = (2.50 × 10^(-2) N⋅m) / ((9.00 × 10^(-2) T) * sin(π / 4))

Compute the result:

μ ≈ 3.54 × 10^(-2) A⋅m²

So, the magnetic moment of the small bar magnet is approximately 3.54 × 10^(-2) A⋅m².

The reason why a change in physical properties would change the capacitance includes the fact that capacitance is affected by the distance between plates, dielectric constants, and dielectric thickness.

Physical properties affect capacitance in so many ways. One of those ways is in the plate area. There is a direct proportional relationship between the capacitance of a substance and the area of its plates.

So an increase in plate area will most likely cause an increase in capacitance and vice versa. Also, there is an inverse relationship between the distance of plates and the capacitance.

4. Doubling the voltage, doubles the strength of the electromagnet

5. The number of paper clips a 7.5 V battery would pick is approximately 28 paper clips

The number of paper clips a 7.5 V battery would pick is 59 paperclips

6. For the 50-coil electromagnet, the average number of paper clips a 1 V battery would pick is approximately 7 paperclips

For the 50-coil electromagnet, the average number of paper clips a 1 V battery would pick is 16 paperclips

Explanation:

3. The Magnetomotive Force, MMF = The Number of Turns on the Coil, N × The Current I Flowing in the Coil, I

∴ MMF = N × I

When the number of turns, N is doubled, the magnetomotive force, MMF is also doubled, and the strength of the electromagnet is doubled

4. Given that the voltage, V applied to the coil = The current, I flowing × The resistance, R of the coil, we have

V = I × R

Therefore, for a given constant resistance in the coil, doubling the voltage, doubles the current and therefore doubles the strength of the electromagnet

5. The average slope for the 25-coil electromagnet = (23 - 12)/(6 - 3) = 3.\(\bar 6\)

The number of paper clips a 7.5 V battery would pick = 12 + (7.5 - 3) × 11/3 = 28.5 paperclips  ≈ 28 paper clips

The average slope for the 50-coil electromagnet = (48 - 26)/(6 - 3) = 7.\(\bar 3\)

The number of paper clips a 7.5 V battery would pick = 26 + (7.5 - 3) × 22/3 = 59 paperclips

6. The slope calculated from a start point of approximately 0.4 V, is given as follows;

The slope for the 25-coil electromagnet = (12 - 6)/(3 - 0.4) = 30/13

Therefore, for the 25-coil electromagnet,  the average number of paper clips a 1 V battery would pick = 6 + (1 - 0.4) × 30/13) = 96/13 ≈ 7 paperclips

The slope for the 50-coil electromagnet = (26 - 13)/(3 - 0.4) = 5

Therefore, for the 50-coil electromagnet,  the average number of paper clips a 1 V battery would pick = 13 + (1 - 0.4) × 5 = 16 paperclips

3. When the number of revolutions, N, is twice, the electromagnet's strength is doubled as well.

4. Doubling the voltage doubles the electromagnet's strength.

5. The number of paper clips selected by a 7.5 V battery is 59.

6. For a 50-coil electromagnet, a 1 V battery would pull up around 7 paperclips on average. The average number of paper clips picked by a 1 V battery for a 50-coil electromagnet is 16 paperclips.

The number of paper clips selected by a 7.5 V battery is;

\(\rm n = 12+ (7.5-+3)\times \frac{11}{3}\\\\n = 28.5\)

For the 50-coil electromagnet, the average slope;

\(\rm (m_{avg})_{50}= \frac{48-26}{6-3} \\\\\ \rm (m_{avg})_{50}= 7\)

The number of paper clips selected by a 7.5 V battery is;

No, conversion of wood to sawdust is an irreversible change, because a block of wood after grounding into sawdust cannot be changed into the same block of wood

The Zenith angle at 45 degrees North during the Spring Equinox is 45 degrees.

The Zenith angle is measured as the angle between the vertical line (directly overhead) and the line connecting the observer to the Sun. During the Spring Equinox, when the Sun is directly above the Equator, the Zenith angle at any latitude is equal to the latitude itself.

To calculate the Zenith angle, Solar elevation angle, and beam spreading at a site located at 45 degrees North on the Autumnal equinox (September 22nd), additional information is needed, such as the time of day and the observer's exact location (longitude). These factors affect the position of the Sun in the sky. The Zenith angle is the angle between the vertical line and the line connecting the observer to the Sun. The Solar elevation angle is the complement of the Zenith angle (90 degrees minus the Zenith angle). Beam spreading refers to the divergence of the solar beam as it travels through the atmosphere, which is influenced by factors such as atmospheric conditions and the Sun's position.

The latitude at which daylight hours have the least variability is the Equator (0 degrees latitude). At the Equator, the length of daylight hours remains relatively constant throughout the year, with minimal variation. In contrast, as you move farther away from the Equator towards the poles, the variability in daylight hours becomes more pronounced, with significant changes between the seasons.

False. The spread of the solar beam, known as beam spreading, is actually greater at higher solar angles (closer to 90 degrees) compared to lower solar angles (closer to 0 degrees). At higher solar angles, the solar beam covers a larger area due to the greater incidence angle, resulting in a larger spread of solar radiation. As the solar angle decreases and approaches 0 degrees, the solar beam becomes more concentrated and focused on a smaller area, leading to a higher intensity of solar radiation at that point.

Distance s=ut+1/2 at^2

If it’s released then this becomes

s=1/2at^2

s=1/2 *9.81*9

s=44.1 m

Explanation:

Answer:

At \(t = (70 / 3) \; {\rm s}\) (approximately \(23.3 \; {\rm s}\).)

Explanation:

Note that the acceleration of the car between \(t = 0\; {\rm s}\) and \(t = 20\; {\rm s}\) (\(\Delta t = 20\; {\rm s}\)) is constant. Initial velocity of the car was \(v_{0} = 0\; {\rm m\cdot s^{-1}}\), whereas \(v_{1} = 35\; {\rm m\cdot s^{-1}}\) at \(t = 20\; {\rm s}\!\). Hence, at \(t = 20\; {\rm s}\!\!\), this car would have travelled a distance of:

\(\begin{aligned}x &= \frac{(v_{1} - v_{0})\, \Delta t}{2} \\ &= \frac{(35\; {\rm m\cdot s^{-1}} - 0\; {\rm m\cdot s^{-1}}) \times (20\; {\rm s})}{2} \\ &= 350\; {\rm m}\end{aligned}\).

At \(t = 20\; {\rm s}\), the truck would have travelled a distance of \(x = v\, t = 20\; {\rm m\cdot s^{-1}} \times 20\; {\rm s} = 400\; {\rm m}\).

In other words, at \(t = 20\; {\rm s}\), the truck was \(400\; {\rm m} - 350\; {\rm m} = 50\; {\rm m}\) ahead of the car. The velocity of the car is greater than that of the truck by \(35\; {\rm m\cdot s^{-1}} - 20\; {\rm m\cdot s^{-1}} = 15 \; {\rm m\cdot s^{-1}}\). It would take another \((50\; {\rm m}) / (15\; {\rm m\cdot s^{-1}}) = (10/3)\; {\rm s}\) before the car catches up with the truck.

Hence, the car would catch up with the truck at \(t = (20 + (10/3))\; {\rm s} = (70 / 3)\; {\rm s}\).

ANSWER and EXPLANATION

We want to determine why a person weighs lighter at the equator.

At the equator, an object will weigh slightly less as a result of the slightly greater centripetal force and the slight increase in distance from the center of gravity of the earth due to the equatorial bulge. This would imply a decrease in the gravitational force that an object experiences.

In other words, the earth is not a perfect sphere, and so, at the equator, an object will be slightly farther from the center.

That is the answer.
