Answer:

kinetic energy = 1/2 X m(v)^2

= 1/2 X 88 X 12

= 528 j

Your question has been heard loud and clear.

Kinetic energy formula= 1/2mv^2

Mass = 88kg (convert to grams because velocity is in m/s)

Mass in grams = 88000g or 88*10^3 g

Velocity= 12m/s

Now kinetic energy = 1/2 * 88000*12*12= 6336 joules

Kinetic energy = 6336 Joules or 6.336 Kilo joules

The energy transferred in Joules by the radio when it has been switched on for 2 minutes would be 6000 Joules.

Power is defined as the rate of energy transfer or the rate at which work is done, and is given by the equation:

Power = Energy transferred / Time

Rearranging the equation to solve for energy transferred, we get:

Energy transferred = Power x Time

We are given:

Power = 50 W

Time = 2 minutes = 120 seconds

Therefore, the energy transferred by the radio when it has been switched on for 2 minutes is:

Energy transferred = Power x Time = 50 W x 120 s = 6000 J

In other words, the energy transferred by the radio is 6000 Joules.

Explanation:

Fn = mg cos(angle )    <======just plug in the values given

Fn = 43 * 9.81 * cos 35 = ~ 346 N

The distance of the balance point of the ruler from zero when the body is moved to the 25cm mark is (14d + 280)/9 cm.

Let X be the mass of the body in grams, and let d be the distance from the pivot to the balance point of the ruler in centimeters when the body is at the 15cm mark.

Total clockwise moment about the pivot = Total anticlockwise moment about the pivot

Clockwise moment due to the ruler = (mass of the ruler) x (distance from the pivot to the ruler's center of gravity)

= (36 g) x (55 cm)

= 1980 g cm

Clockwise moment due to the body = (mass of the body) x (distance from the pivot to the body)

= X g x (15 cm)

= 15X g cm

Anticlockwise moment due to the ruler = (mass of the ruler) x (distance from the pivot to the balance point of the ruler)

= (36 g) x (d - 30 cm)

= 36 (d - 30) g cm

Anticlockwise moment due to the body = (mass of the body) x (distance from the pivot to the balance point of the ruler)

= X g x (30 - d) cm

= 30X g cm - Xd g cm

Equating the clockwise and anticlockwise moments, we have:

1980 g cm + 15X g cm = 36 (d - 30) g cm + 30X g cm - Xd g cm

Simplifying and rearranging, we get:

45X g = 6 (d - 30) g + 1980 g

45X g = 6d g - 180 g + 1980 g

45X g = 6d g + 1800 g

X = (6d + 1800)/45 g

X = (2d + 600)/15 g

Therefore, the mass of the body is (2d + 600)/15 grams.

1980 g cm + 25X g cm = 36 (e - 30) g cm + 30X g cm - Xe g cm

45X g = 6 (e - 30) g + 1980 g - 25X g

45X g = 6e g - 180 g + 1980 g - 25X g

45X g + 25X g = 6e g + 1980 g - 180 g

70X g = 6e g + 1800 g

e = (70X + 1800)/6 g

e = (35X + 900)/3 g

Substituting X = (2d + 600)/15 g, we get:

e = (35/3)((2d + 600)/15) + 900/3 g

e = (14d + 280)/9 g

Therefore, the distance of the balance point of the ruler from zero when the body is moved to the 25cm mark is (14d + 280)/9 cm.

Answer:

Volume flow rate is the same in both sections of the pipe

Explanation:

No, intensity level does not follow inverse square law.

The square of the distance between the source and the observer determines how intense the light is for the observer. This demonstrates that the intensity of light is proportional to a value multiplied by 1/d² as the distance to a light source increases.

Here,

intensity level = 53 dB

distance, d = 4.4 m

part A)

let the intensity is I

Intensity level = 10×log(l/1×10⁻¹²)

53 = 10 ×log(1/1×10⁻¹²)

solving for I

I = 1.995 ×10⁻⁷ W/m²

the intensity of sound at A is 1.995 ×10⁻⁷W/m²

part B)

for the sound intensity to be one fourth.

as sound intensity = 1/(4×π×d²)

hence, the distance must be made two times,

new distance = 4.4 ×2

new distance = 8.8 m

the distance from the source is 8.8 m

part C)

distance to move from point A = 8.8 - 4.4

distance to move from point A = 4.4 m

part D)

yes, the intensity follow the inverse square law

part E)

for the intensity level,

as I = 10 × log(P/(4×π×d²×10))

hence, intensity level does not follow inverse square law.

The masses of the two objects MA and MB in the binary system are 4 Mo respectively.

The masses of binary systems can be calculated using Kepler's laws of planetary motion and observations of the system.

Let's denote the masses of the two objects as MA and MB, where MA is the mass of object A and MB is the mass of object B. We know that the total mass of the binary system is 8 Mo, so:

MA + MB = 8 Mo

We also know that the ratio of the distances between the two objects is 1/3. Let's denote the distance between the two objects as d, so we have:

d(A to B) / d(Binary System) = 1/3

We can simplify this equation by using the fact that the distances between the objects and the binary system add up to the total distance between the objects:

d(A to B) + d(B to binary system) = d(Binary system)

Since we know the ratio of the distances, we can substitute 1/3d for d(B to binary system):

d(A to B) + 1/3d = d(Binary system)

3d(A to B) + d = 3d(Binary system)

Substituting d(A to B) for d(Binary system) - d(B to binary system), we get:

3d(A to B) + d = 3(d(A to B) + d(B to binary system))

2d(A to B) = 2d(B to binary system)

d(A to B) / d(B to binary system) = 1

So the two objects are at the same distance from the binary system center of mass. This means that the masses of the two objects are equal:

MA = MB

Substituting this into the first equation, we get:

2MA = 8 Mo

MA = MB = 4 Mo

Therefore, the mass of each object is 4 Mo.

Wavelength of the given wave is 8 cm and frequency is  37.5 *\(10^{8}\) Hz.

The number of vibrations counted per second is called frequency. A wave is a group of vibrations that are referred to as energy. The bottom node is known as the crest, and the top node is known as the trough.

The frequency of an alternating current is the number of full cycles per second. The hertz, also known as Hz, is the accepted unit of frequency. The frequency of a current is 1 Hz if one cycle is completed per second; 60 cycles per second equals 60 Hz.

There are 8 waves so assume one wave is 1 cm so wavelength is 8 cm and frequency of wave = speed of light/ wavelength

frequency = \(3*10 ^{8} / .08\)

Frequency = 37.5 *\(10^{8}\) Hz
