The power of the modulated signal is 5 W. The maximum phase shift is 1050 radians. The maximum frequency deviation is 20 Hz.

An angle modulated wave is described by the equation, Φ(t) = 10 cos [2π x 109 t + 10 cos 2π x 105 t].

We need to find the power of the modulated signal, the maximum phase shift, and the maximum frequency deviation.

i) The power of the modulated signal: The power of the modulated signal can be calculated using the formula: \(P = Ac^{2 / 2}\), where A is the amplitude of the modulated signal, and c is the modulation index.

A = 10; frequency of carrier wave = fc = 109 Hz; frequency of modulating signal = fm = 105 Hz

Modulation index, c = (amplitude of modulating signal / amplitude of carrier signal) = (10 / 10) = 1

Therefore, \(P = Ac^{2 / 2}= 10 x 1^{2 / 2}= 5 W\)

Thus, the power of the modulated signal is 5 W.

ii) The maximum phase shift: Maximum phase shift, θm = amplitude of modulating signal x frequency of carrier waveθm = 10 x 105= 1050 radians

Thus, the maximum phase shift is 1050 radians.

iii) The maximum frequency deviation: Maximum frequency deviation can be calculated using the formula, Δf = (frequency deviation sensitivity x modulating signal voltage) / carrier frequency frequency deviation sensitivity = 2 x modulation index x carrier frequency = 2 x 1 x 109= 2 x 109 Hz/V

Modulating signal voltage, Vm = amplitude of modulating signal = 10 V Carrier frequency, fc = 109 Hz

Therefore,Δf = (frequency deviation sensitivity x modulating signal voltage) / carrier frequency= (2 x 1 x 109 x 10) / 109= 20 Hz

Thus, the maximum frequency deviation is 20 Hz.

The edge of a disk with a radius of 12. 5 cm if it completes 10 revolutions in 4. 18 s:

a) The angular speed is 15.02 radians per second.

b) The tangential velocity is 187.75 cm/s.

a) To find the angular speed, we need to determine the angle covered by the disk in the given time. One revolution corresponds to an angle of 360 degrees or 2π radians. Therefore, 10 revolutions correspond to an angle of 10 × 2π = 20π radians.

The time taken to complete these 10 revolutions is given as 4.18 seconds. We can calculate the angular speed using the formula:

Angular Speed = Angle / Time

Angular Speed = (20π radians) / (4.18 seconds)

Angular Speed = (20π radians) / (4.18 seconds) ≈ 15.02 radians per second.

b) To find the tangential velocity at the edge of the disk,

Tangential Velocity = Radius × Angular Speed

Tangential Velocity = (12.5 cm) × (Angular Speed)

Tangential Velocity = (12.5 cm) × (15.072 radians per second) ≈ 187.75 cm/s.

Therefore, the angular speed of the disk is approximately 15.072 radians per second, and the tangential velocity at the edge of the disk is approximately 187.75 cm/s.

So, in Activity 2-2, if the coil is pulled away from the north pole of a magnet, it is likely that an EMF will be induced in the coil.

However, based on general principles of electromagnetism, if a coil is pulled away from the north pole of a magnet, it will experience a change in magnetic flux, which can induce an electromotive force (EMF) in the coil. This phenomenon is known as electromagnetic induction.

The magnitude and direction of the induced EMF will depend on several factors, such as the strength of the magnet, the velocity at which the coil is moved, and the orientation of the coil with respect to the magnetic field. If the coil is part of a circuit, the induced EMF can cause a current to flow in the circuit.

Elastic force: Elastic is the ability of a material to return to its original shape after being compressed or stretched.

Elastic force is the force exerted by an elastic material when it is stretched or compressed. Elastic materials, such as rubber bands, springs, and some types of plastics, have the ability to return to their original shape and size after being deformed by an external force.

When an elastic material is stretched or compressed, the molecules within the material are forced to move apart or come closer together. This creates a tension or compression force within the material that opposes the external force applied to it. The magnitude of the elastic force depends on the amount of deformation and the elasticity of the material.

Explanation:

Given that,

Acceleration = 29.4 m/s²

Time = 7.00 s

We need to calculate the distance

Using equation of motion

\(s=ut+\dfrac{1}{2}at^2\)

Put the value into the formula

\(s=0+\dfrac{1}{2}\times29.4\times7^2\)

\(s=720.3\ m\)

We need to calculate the velocity

Put the value into the formula

\(v=29.4\times7\)

\(v=205.8\ m/s\)

We need to calculate the height

Using formula of height

\(H=\dfrac{v^2}{2g}\)

Put the value into the formula

\(H=\dfrac{(205.8)^2}{2\times9.8}\)

\(H=2160.9\ m\)

We need to calculate the maximum height

Using formula for maximum height

\(H'=H+s\)

The magnitude of the force between the wires per unit length, f, is given by: f = (2 * 10⁻⁷ * I1 * I2) / d

The force between two parallel wires carrying currents can be calculated using Ampere's Law.

According to Ampere's Law, the force per unit length (f) between two parallel wires is directly proportional to the product of their currents (I1 and I2) and inversely proportional to the distance between the wires (d).

The formula for the force per unit length between two parallel wires is:

f = (2 * 10⁻⁷ * I1 * I2) / d

I1 = 0.65 A (current in the first wire)

I2 = 0.35 A (current in the second wire)

d = 0.065 m (distance between the wires)

Substituting these values into the formula, we get:

f = (2 * 10⁻⁷* 0.65 * 0.35) / 0.065

Simplifying the expression:

f = 6.76 * 10⁻⁶ N/m

Therefore, the magnitude of the force between the wires per unit length is approximately 6.76 * 10⁻⁶ N/m.

The magnitude of the force between two long, parallel wires per unit length (f) can be calculated using the formula f = (2 * 10⁻⁷ * I1 * I2) / d, where I1 and I2 are the currents in the wires and d is the distance between them.

In this case, the magnitude of the force per unit length is approximately 6.76 * 10⁻⁶ N/m.

The Earth orbits the sun at a distance of around 93 million miles (149.6 million kilometers). This is known as an astronomical unit (AU).

With a diameter of 12,742 kilometers (7,918 miles), the Earth is basically spherical. It has a bulge near the equator and a slight flattening at the poles.

Seasons change as the Earth rotates around the Sun due to its leaning position of 23.5-degree axial tilt. Summer occurs when the sun is facing the hemisphere, while winter happens in the other hemisphere.

Leap years are added to the calendar to account for the extra quarter of a day that it takes the Earth to orbit around the Sun. Without leap years, our calendars would fall out of sync with the seasons.

The Earth's motion affects the seasons on Earth due to the axial tilt mentioned earlier. The hemisphere tilted towards the Sun experiences more direct sunlight, causing it to be warmer and experience summer, while the hemisphere tilted away experiences less direct sunlight and cooler temperatures, causing winter.

Answer:

acceleration = 0.2 m/s/s

Explanation:

initial velocity u = 14

final velocity v = 20

time = 30

acceleration = ?

v = u + at

20 = 14 + 30a

30a = 6

a = 0.2 m/s/s

Answer:

For the aceleration we have:

V = Vi + a * t

Being:

V = 20 m/s

Vi = 14 m/s

a = ?

t = 30 s

Then, lets replace acording the formula:

20 m/s = 14 m/s + a * 30 s

Clear "a":

a = (20 m/s - 14 m/s) / 30 s

a = (6 m/s) / 30 s

a = 0,2 m/s²

The aceleration of the car is 0,2 meters per second squared.

Among the reasons for the frequent use of composite measures is that they give a more comprehensive and accurate indication of a given variable. Besides, the researcher is seldom able to develop in advance single indicators of complex concepts. A single data item might not have enough categories to provide a range of variation. And lastly, they are efficient data reduction devices.

So, the correct answer is option (e) all of these choices.

Composite measures are used to combine several variables or scores into a single measurement or index. In other words, they are multidimensional measurement tools. It is useful to make this kind of index because it is possible to calculate the reliability and validity of composite measures, which are statistical measures that indicate whether or not the measurements were conducted accurately or are otherwise legitimate.

For example, if a researcher wants to assess the economic development of a country, he/she could create a composite measure by combining data on GDP per capita, literacy rates, and poverty rates. In this case, each of the three variables reflects a different aspect of economic development.

Depends on the location of the two forces.  If they are aligned on the same side of the object, you would simply add.

X -----------F1 -------F2

X is the object. F1 and F2 are both masses which create a gravitational force. They both are the form of Fx = G * m1 * m2 / r^2. The total force is F1 + F2

If they are are on either side of the object, you subtract.

F1 ---------X ---------F2

Fx = F1 - F2

Any other location of F1 and F2 is much more complicated by the use of trigonometry.

A person's weight is 51kg. The gravitational force is 9.8 m/s². One snowshoe has a surface area of 0.2m2. The pressure applied when standing on (A) one snowshoe and (B) both snowshoes is 2.499 kPa.

The pressure applied by a person standing on the snowshoe is given by the formula:

Pressure = Force / Area

where Force is the weight of the person and Area is the area of one snowshoe.

(A) When standing on one snowshoe:

The force exerted by the person on one snowshoe is equal to the weight of the person:

Force = 51 kg x 9.8 m/s² = 499.8 N

Therefore, the pressure applied by the person on one snowshoe is:

Pressure = Force / Area = 499.8 N / 0.2 m² = 2499 Pa = 2.499 kPa (to three decimal places)

(B) When standing on both snowshoes:

The force exerted by the person on both snowshoes is twice the weight of the person:

Force = 2 x 51 kg x 9.8 m/s² = 999.6 N

Therefore, the pressure applied by the person on both snowshoes is:

Pressure = Force / Area = 999.6 N / (2 x 0.2 m²) = 2499 Pa = 2.499 kPa (to three decimal places)

Hence, the pressure applied by the person when standing on one snowshoe or both snowshoes is the same, and it is equal to 2.499 kPa (to three decimal places).

Explanation:

We are given;

Speed of car A; V_a = 30 m/s

Speed of car B; V_b = 110 km/h

Now, V_a is already in m/s, so let's convert V_b to m/s too.

From conversions, 36 km/h = 10 m/s, therefore, 110 km/h would give;

(110 × 10)/36 = 30.56 m/s

Thus, V_b = 30.56 m/s

Comparing both speeds in m/s, we can see that 30.56 m/s > 30 m/s.
