Which object is an example of a mechical wave

The binding energy of a nucleus wil be . B = 0.999568 u * (1.66 x 10⁻²⁷ kg/u) * (3.00 x 10⁸ m/s)²

Calculating the above expression will give us the binding energy B in joules (J).

The binding energy of a nucleus can be calculated by using the mass defect, which is the difference between the mass of the nucleus and the sum of the masses of its individual nucleons (protons and neutrons).

To find the binding energy of the last neutron in silicon-29, we need to compare the masses of silicon-29 (29 nucleons) and silicon-28 (28 nucleons).

The mass defect (Δm) is given by:

Δm = (mass of silicon-29) - (mass of silicon-28)

Δm = 28.976495 u - 27.976927 u

Δm = 0.999568 u

The binding energy (B) can be calculated using Einstein's mass-energy equivalence principle (E = mc²), where c is the speed of light:

B = Δm * c²

Now we need to convert the atomic mass unit (u) to kilograms (kg) for consistent units. We know that 1 u is approximately equal to 1.66 x 10⁻²⁷ kg.

B = 0.999568 u * (1.66 x 10⁻²⁷ kg/u) * (3.00 x 10⁸ m/s)²

Calculating the above expression will give us the binding energy B in joules (J).

Note: It is important to double-check and verify the values and constants used in the calculation for accuracy.

Trees are being felled at an alarming rate by people. Forests are home to numerous animals and people, and by removing trees from them, we are destroying their habitat and depriving them of a safe haven.

Community conservation refers to a strategy for protecting the environment that acknowledges local residents' rights to manage wildlife or gain both direct and indirect benefits from it.

The gorillas' habitat, the forest, is being destroyed by humans. Additionally, people are harming these creatures, and if this continues, gorillas may become extinct.

There won't be as many resources from trees, like paper, if people cut down less of them, therefore prices could rise.

Prices for tourists will increase if fewer gorillas are still alive. That won't benefit visitors since they will have to pay more, and since some individuals don't have a lot of money, there will be fewer visitors.

Thus, this way, community conservation is mandatory.

The merry-go-round takes approximately 29.41 seconds to complete 2.00 rotations.

Given data:

Acceleration (α) = 0.135 rad/\(s^2\)

Number of rotations (θ) = 2.00

To find the time taken (t) for 2.00 rotations, we need to use the formula:

θ = 0.5 * α * \(t^2\)

Rearranging the formula, we get:

\(t^2\) = (2 * θ) / α

Plugging in the given values, we have:

\(t^2\) = (2 * 2.00) / 0.135

\(t^2\) = 29.63

Taking the square root of both sides, we find:

t ≈ √29.63

t ≈ 5.439

Therefore, the time taken for the merry-go-round to complete 2.00 rotations is approximately 5.439 seconds.

Note: It's important to round the final answer to an appropriate number of significant figures, considering the given data. In this case, we have used four significant figures in the final answer.

However, if we want to adhere to the given significant figures in the acceleration (0.135 rad/\(s^2\)), the answer should be rounded to three significant figures. In that case, the final answer would be approximately 5.44 seconds.

To make the force on charge q zero, its magnitude should be\([2/\sqrt{2} ) * [(kQ)/l^2]\), and its sign will depend on the charges at the top right and bottom left corners of the square.

To make the force on charge q zero in the given configuration, we need to determine the appropriate magnitude and sign of charge q.

Let's analyze the forces acting on charge q due to the other charges. Each charge at the corners of the square will exert a force on charge q based on the Coulomb's law, given by \(F = k * (|q1| * |q2|) / r^2\), where F is the force between the charges, k is the electrostatic constant, \(q_1\)and \(q_2\) are the charges, and r is the distance between the charges.

Considering charge q located at one of the corners, it will experience equal and opposite forces from the charges on two adjacent corners of the square, resulting in a net force of zero in the horizontal and vertical directions. Thus, the total force acting on charge q will be zero if the magnitudes of the two forces are equal.

Now, let's assume that the charges at the corners of the square are all positive. To cancel out the forces, charge q should be negative to attract the positive charges and balance the forces. By adjusting the magnitude of charge q, we can ensure that the magnitudes of the two forces are equal.

Therefore, to make the force on charge q zero in this configuration, charge q should have a negative sign with a magnitude equal to the magnitude of the charges at the corners of the square.

Answer:

Efficiency = 10.2 %

Explanation:

Given the following data;

Mass = 70 kg

Height = 50 m

Velocity = 10 m/s

We know that acceleration due to gravity is equal to 9.8 m/s².

To find the efficiency of energy conversion from potential to kinetic;

First of all, we would determine the potential energy;

P.E = mgh

P.E = 70 * 9.8 * 50

P.E = 34300 J

For the kinetic energy;

K.E = ½mv²

K.E = ½ * 70 * 10²

K.E = 35 * 100

K.E = 3500

Therefore, Input energy, I = 34300 J

Output energy, O = 3500 J

Next, we find the efficiency;

Efficiency = O/I * 100

Substituting into the formula, we have;

Efficiency = 3500/34300 * 100

Efficiency = 0.1020 * 100

Efficiency = 10.2 %

(a) The work function of potassium is 2.21 eV. (b) The cutoff wavelength is approximately 304 nm. (c) The frequency corresponding to the cutoff wavelength is approximately 9.87 x 10¹⁴ Hz.

(a) The maximum kinetic energy of the emitted electrons can be related to the work function, W, by the following equation:

KEmax = hν - W

where h is Planck's constant, ν is the frequency of the light, and W is the work function. We can rewrite this equation in terms of the wavelength, λ, using the relation c = λν, where c is the speed of light. Thus,

KEmax = hc/λ - W

Substituting the given values, we have:

KEmax = 1.31 eV = (6.626 x 10⁻³⁴ J s)(3.00 x 10⁸ m/s)/(350 x 10⁻⁹m) - W

Solving for W, we get:

W = 2.21 eV

Therefore, the work function of potassium is 2.21 eV.

(b) The threshold wavelength, λ0, is the minimum wavelength required to eject an electron from the surface of the metal. This occurs when the kinetic energy of the electron is just equal to zero. Thus, we have:

KEmax = hc/λ - W = 0

Solving for λ, we get:

λ0 = hc/(KEmax + W)

Substituting the given values, we have:

λ0 = (6.626 x 10⁻³⁴ J s) (3.00 x 10⁸ m/s) / (1.31 eV + 2.21 eV) (1.60 x 10⁻¹⁹  J/eV)

λ0 ≈ 304 nm

Therefore, the cutoff wavelength is approximately 304 nm.

(c) The frequency corresponding to the cutoff wavelength can be found using the relation c = λν, where c is the speed of light. Thus,

ν = c/λ0

Substituting the given values, we have:

ν = (3.00 x 10⁸ m/s)/(304 x 10⁻⁹m)

ν ≈ 9.87 x 10¹⁴ Hz

Therefore, the frequency corresponding to the cutoff wavelength is approximately 9.87 x 10¹⁴ Hz.

The bird travels a total distance of 92 km. When the two trains are 46 km apart, the bird starts flying from one train toward the other train.

Let's assume that the distance between the bird and the first train is x km. Since the bird is flying towards the other train at a speed of 46 km/h and the trains are moving towards each other at a combined speed of 46 km/h, the relative speed of the bird with respect to the first train is

69 km/h (46 km/h + 23 km/h).

Therefore, it takes the bird x/(69 km/h) hours to reach the second train.

During this time, the two trains move towards each other and reduce the distance between them by

Therefore, the distance between the bird and the second train is also x km. Now, the bird starts flying towards the first train at the same speed of 46 km/h. Again, it takes the bird

hours to reach the first train.
