If the trophic efficiency for an ecosystem is 20% and secondary consumers have net production of 100 J, the net production of primary producers would be 2500 J..

An ecosystem with a trophic efficiency of 20% is an indication that only 20% of the energy available at a particular trophic level is transferred to the next trophic level.

In other words, the amount of available energy decreases progressively at every trophic level. Secondary consumers are at level 3 of the energy pyramid. Below them would be primary consumers and primary producers.

Now, we are saying that 100 J of energy is available at the secondary consumer level. This means that 100 J is 20% of the total amount of energy available at the primary consumer level.

If 20% = 100 J

  100% = 100 x 100/20

            = 500 J

At the level of the primary producers:

If 20% = 500 J

  100% = 500 x 100/20

            = 2500 J

In other words, the net production of primary producers in that ecosystem would be 2500 J.

Part A: The diameter of the path followed by the alpha particle is approximately 0.285 meters (to 3 significant figures).

The path followed by a charged particle in a magnetic field can be determined using the formula for the radius of the circular path: r = (m*v) / (q*B), where r is the radius, m is the mass of the particle, v is its velocity, q is its charge, and B is the magnetic field strength.

Given the mass of the alpha particle (m = 6.64x10^(-27) kg), its velocity (v = 35.6 km/s = 35.6x10^3 m/s), the charge of an alpha particle (q = 2 times the charge of an electron), and the magnetic field strength (B = 1.20 T), we can calculate the radius of the path.

Plugging in the values into the formula, we have: r = (6.64x10^(-27) kg * 35.6x10^3 m/s) / (2 * 1.60x10^(-19) C * 1.20 T) = 0.285 meters.

Therefore, the diameter of the path followed by the alpha particle is approximately 0.285 meters.

Part C: The magnitude of the acceleration of the alpha particle while it is in the magnetic field is 8.92x10^12 m/s^2 (to 3 significant figures).

The acceleration of a charged particle moving in a magnetic field is given by the formula: a = (q * v * B) / m, where a is the acceleration, q is the charge of the particle, v is its velocity, B is the magnetic field strength, and m is its mass.

Using the given values, we can calculate the acceleration: a = (2 * 1.60x10^(-19) C * 35.6x10^3 m/s * 1.20 T) / 6.64x10^(-27) kg = 8.92x10^12 m/s^2.

Therefore, the magnitude of the acceleration of the alpha particle while it is in the magnetic field is approximately 8.92x10^12 m/s^2.

Answer:

A) lacks the mass of the object

The value of the acceleration is 0.76 m/s² and the total time taken by the vehicle is 39 seconds.

The acceleration of the vehicle before coming to rest is calculated as follows;

v² = u² + 2as

where;

the car came to rest with constant velocity attained after 12 seconds.

the initial velocity of the car before 12 seconds is zero.

v² = 0 + 2as

a = v²/2s

a = (10²)/(2 x 66)

a = 0.76 m/s²

d = ut + ¹/₂at²

where;

580 = 0 + ¹/₂(0.76)t²

580 = 0.38t²

t² = 580/0.38

t² = 1,526.3

t = √1,526.3

Your answer :- Increase

Normal force :- The normal force is the force that surfaces exert to prevent solid objects from passing through each other.

Here's a step-by-step explanation:

1. Newton's second law states that the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma). In this case, the net force is the difference between the normal force (N) and the weight (W) of the person, and the acceleration is the centripetal acceleration (ac).

2. The equation you provided is N - W = mac, where ac = v^2/r.

3. When the velocity (v) of the Ferris wheel increases, the centripetal acceleration (ac) also increases, because ac is proportional to the square of the velocity (ac = v^2/r).

4. Since the centripetal acceleration increases, the product of mass (m) and centripetal acceleration (mac) also increases.

5. To maintain the balance in the equation N - W = mac, the normal force (N) must increase to compensate for the increase in mac.

So, when the velocity of the Ferris wheel increases, the  must increase.

Explanation:

From the question given above, the following data were obtained:

Weight on earth = 784 N

Acceleration due to gravity of the moon (gₘ) = 1.6 m/s²

Weight on moon =?

Next, we shall determine the mass of the person. This can be obtained as follow:

Weight on earth (Wₑ) = 784 N

Acceleration due to gravity of earth (gₑ) = 10 m/s²

Mass (m) =?

Wₑ = m × gₑ

784 = mass × 10

Divide both side by 10

Mass = 784 / 10

Mass = 78.4 Kg

Finally, we shall determine the weight of the person on moon. This can be obtained as follow:

Mass (m) = constant = 78.4 Kg

Acceleration due to gravity of the moon (gₘ) = 1.6 m/s²

Weight on moon (Wₘ) =?

Wₘ = m × gₘ

Wₘ = 78.4 × 1.6

Wₘ = 125.44 N

Therefore, the weight of the person on moon is 125.44 N.

To determine which compound has the longest wavelength lambda_max in its UV spectrum, we need to consider the extent of its conjugation system. Compounds with a larger conjugation system have a lower energy gap between their HOMO and LUMO, and therefore, they absorb light at longer wavelengths.

The compound with the most extensive conjugation system is typically the one with the longest lambda_max. Therefore, the compound with the longest wavelength lambda_max in its UV spectrum would be the one with the most extended conjugation system. In conclusion, the compound with the most extended conjugation system will have the longest wavelength lambda_max in its UV spectrum.

This is true because the process of dry ice sublimating and the puddle freezing both involve chemical bonds breaking.

In the case of dry ice (solid CO2), the sublimation process occurs when the CO2 molecules absorb enough energy to break the bonds holding them together in a solid state. This energy is supplied by the surrounding air, causing the CO2 to transition directly from a solid to a gas.

In the case of the puddle freezing, the water molecules lose energy and slow down, allowing hydrogen bonds to form between the molecules. As more and more bonds form, the liquid transitions to a solid (ice). The breaking of hydrogen bonds in the liquid and the formation of new bonds in the solid are chemical processes that represent a breaking and forming of chemical bonds.

In an ideal fluid, the sum of kinetic energy per unit volume (also known as the velocity head) and pressure is known as the total head and is a constant along a streamline. This is described by the Bernoulli's equation, which states that the total head is constant along a streamline as long as the fluid is incompressible and frictionless. Therefore, if the pipe diameter varies along its length, the total head would remain the same at different sections of the pipe, even though the kinetic energy and pressure would change.

The expansion of a 13L steel scuba tank can be ignored when evaluating the mass of air inside because the volume increase due to expansion is very small compared to the tank's original volume. It is a good approximation.

The expansion of a 13L steel scuba tank occurs due to changes in temperature and pressure. When the tank is filled with air, the air inside the tank is also affected by these changes. However, the volume increase due to expansion is typically very small compared to the original volume of the tank. As a result, the mass of air inside the tank can be evaluated without taking into account the expansion of the tank. This is a good approximation because the expansion is negligible in comparison to the total volume of the tank. However, it's worth noting that if a more precise calculation is required, the expansion of the tank should be taken into account.

Therefore, we cannot calculate the exact time for one cycle without more information.

The time for one cycle of a planet around the Sun is determined by its orbital period, which is related to the average distance of the planet from the Sun. In this case, if the average distance of the planet from the Sun is 21 astronomical units (A.U.), we can use Kepler's Third Law to calculate the orbital period.

Kepler's Third Law states that the square of the orbital period (T) is proportional to the cube of the average distance (r) between the planet and the Sun. Mathematically, it can be expressed as:

T^2 = k * r^3

Where k is a constant.

Given that the average distance is 21 A.U., we can set up the following equation:

T^2 = k * 21^3

To solve for T, we need the value of the constant k. However, without further information or additional equations, we cannot determine the specific value of k. Therefore, we cannot calculate the exact time for one cycle without more information.
