Answer:

The acceleration is 8 m/s²

Explanation:

The given parameters are;

The initial velocity, u = 2 m/s

The final velocity, v = 6 m/s

The distance the acceleration took place, s = 2 m

The acceleration, a, can be found from the following kinematic equation;

v² = u² + 2·a·s

By substituting the values, we have;

6² = 2² + 2 × a × 2

6² - 2² = 2 × a × 2

32 = 4·a

a = 32/4 = 8 m/s²

The acceleration, a, of the given motion = 8 m/s².

The required speed at an altitude of 8.6 km to satisfy Mach number similarity is approximately 630.14 km/hr. To understand why this is the case, we need to consider the concept of Mach number similarity. Mach number is a dimensionless quantity that represents the ratio of an object's speed to the speed of sound in the surrounding medium. It is denoted by the symbol "M."

For Mach number similarity to be maintained, the ratio of the aircraft's speed to the speed of sound at both altitudes must remain the same. This is because the speed of sound changes with altitude due to variations in air temperature and pressure.

To calculate the required speed at an altitude of 8.6 km, we can use the following formula:

M1 = M2 * (T1 / T2)^0.5

Where M1 and M2 are the Mach numbers at the respective altitudes, and T1 and T2 are the temperatures at those altitudes. Since we want to find the speed, we can rearrange the formula as follows:

V2 = M2 * (T2 / T1)^0.5 * V1

Given that the speed at an altitude of 15 km is 1120 km/hr and the altitude is 8.6 km, we can calculate the required speed using the above formula. By plugging in the values, we find that the required speed at an altitude of 8.6 km to satisfy the Mach number similarity is approximately 630.14 km/hr.

Explanation:

potential energy ===> kinetic energy

when an object is stretched there will be a stored energy in it enough to react to the upcoming change

that is the potential energy

similar to a stretched elastic band

kinetic energy is the energy on a moving object

*If a kinetic energy takes place there must gave been a potential energy before*

A catapult is used to fire an object into the air, the potential energy transfers as the elastic potential energy and to the kinetic energy when the catapult is released and stretched.

The potential energy is associated with bodies that are above a reference point, at that reference point the value of potential energy is taken as zero. For example, if an object with a mass M is in a tower that is 140 meters high, its potential energy is defined as the product of the mass of the object by gravity and by the height at which the object is measured from the reference point.

Ep =mgh

When talking about elastic objects such as springs or elastic fibers, it is usually understood that there is an elastic potential energy associated with the constant of the spring. This can be calculated using the following equation:

U ela = 1/2×k×(Dx)²

where:

k = elastic constant of the elastic material [N/m]

Dx = distance stretched or compressed of the elastic material [m]

U = elastic energy [Joules]

So, there are difference between the elastic potential energy and the potential energy.

In a catapult, Initially, energy is stored in the form of potential energy which is later converted into kinetic energy. Potential energy can be stored in the form of elastic potential energy in the case of elastic. It suddenly releases the energy to propel the object into the air.

The wavelength of the emitted photon is 5.48 x 10^-17 m, and the mass of the particle is 1.05 x 10^-26 kg.

The energy levels of a particle in a one-dimensional box are given by:

En = (n^2 * h^2)/(8mL^2)

where n is the quantum number, h is Planck's constant, m is the mass of the particle, and L is the length of the box.

We are given En = 51.5 MeV and En+1 = 74.2 MeV, and L = 10 fm.

Using En, we can find the mass of the particle:

m = (n^2 * h^2)/(8L^2 * En)

m = (5^2 * (6.626 x 10^-34 J s)^2) / (8 * (10 x 10^-15 m)^2 * (51.5 x 10^6 eV) * (1.602 x 10^-19 J/eV))

m = 1.05 x 10^-26 kg

Now, we can find the wavelength of the photon emitted in the n+1 to n transition using the formula:

ΔE = Efinal - Einitial = hc/λ

where ΔE is the energy difference between the two levels, h is Planck's constant, c is the speed of light, and λ is the wavelength of the emitted photon.

ΔE = En+1 - En = 74.2 MeV - 51.5 MeV = 22.7 MeV

Converting MeV to joules:

ΔE = 22.7 MeV x (1.602 x 10^-13 J/MeV) = 3.63 x 10^-12 J

Plugging in the values, we get:

λ = hc/ΔE

λ = (6.626 x 10^-34 J s) * (3.00 x 10^8 m/s) / (3.63 x 10^-12 J)

If a magnet is held stationary relative to a coil, no electromotive force (emf) is induced in the coil, or the induced emf is zero.

The phenomenon of electromagnetic induction, which is responsible for the generation of emf in a coil, occurs when there is a relative motion between a magnetic field and the coil. When a magnetic field moves or changes relative to a coil, the magnetic field lines passing through the coil are altered, inducing an emf according to Faraday's law of electromagnetic induction.

However, if the magnet is held stationary relative to the coil, there is no relative motion between the magnetic field and the coil, and therefore no change in the magnetic field lines passing through the coil. As a result, no emf is induced in the coil.

In order to induce an emf in a stationary coil, there must be relative motion between the magnet and the coil, such as the magnet being moved towards or away from the coil, or the coil being moved through a magnetic field.

Explanation:

The voltage of the battery in your car is always 12 to 13.5 volts. It makes no difference whether the car is home in the garage or zooming down the interstate.

The frequency of the wave on a rope is found to be 20s^-1

The degree of direction changes of current per second is defined as frequency. It is expressed in hertz (Hz), a unit of measurement that is used globally. One hertz is equivalent to one cycle per second. One hertz (Hz) is comparable to one cycle per second.

Speed of wave (V) => 100cm/s

Wavelength λ = 5cm

Wave speed = Frequency X Wavelength

      100cm/s/5cm => frequency (f)

f => 20s^-1

Frequency and wavelength are inversely proportional to one another, as shown by the equation v = f. Any increase in the frequency generates a subsequent fall in wavelength when the velocity remains unchanged. As a result, the correlation between wavelength and frequency is inverse.

distance = speed × time

distance = 2 m/s × 3 s = 6 meters

b)

The distance travelled in the first 3 seconds=  6 meters.

The distance travelled from 3 seconds to 7 seconds, which can be found by finding the area under the trapezium formed by the line joining (3, 2) and (7, 4), the x-axis and the vertical lines at x=3 and x=7.

The height of the trapezium is (4 - 2) m/s = 2 m/s, and the two bases are 4 s - 3 s = 1 s and 7 s - 3 s = 4 s, respectively.

the area of the trapezium is:

area = (1/2) × (1 + 4) s × 2 m/s = 7 meters

The total distance travelled is therefore:

total distance = distance travelled in the first 3 seconds + distance travelled from 3 seconds to 7 seconds

The mass of an American Eagle silver bullion coin is approximately 31 grams.

What is American Eagle silver bullion?

American Eagle Silver Bullion refers to a popular silver investment coin produced by the United States Mint. It was first introduced in 1986 as part of the American Eagle Bullion Program, which also includes gold and platinum coins. The American Eagle Silver Bullion coin contains one troy ounce of 99.9% pure silver and has a face value of one dollar.

To calculate the mass of the silver bullion coin, we need to find its volume and then multiply it by the density of silver. The volume of the coin can be calculated using its dimensions.

The coin has a diameter of 40.6 millimeters, which can be converted to centimeters by dividing by 10. Therefore, the diameter is 4.06 centimeters. The coin is 2.98 millimeters thick, which is equivalent to 0.298 centimeters.

The volume of a cylinder, which represents the coin, is given by the formula: volume = π × r² × h, where r is the radius and h is the height (or thickness) of the cylinder. The radius can be found by dividing the diameter by 2. So, the radius is 4.06 / 2 = 2.03 centimeters.

Using the values of radius (2.03 cm) and height (0.298 cm) in the volume formula, we can calculate the volume of the coin. Then, by multiplying the volume by the density of silver (10.5 grams per cubic centimeter), we can find the mass of the coin.

After performing the calculations, the mass of the American Eagle silver bullion coin is approximately 31 grams.
