The wavelength of the sound wave in the air column closed at one end is given by

where n = 1, 3, 5, 7,9, 11, 13, 15 are all odd numbers.

Now in our case, we know that the length of the pipe is 225 or 2.25 m. The 8th resonance corresponds to n = 15; therefore, the wavelength of the sound wave is

Hence, the wavelength of the sound wave is 60 cm.

The mirror is polished smooth, so that regular reflection occurs. the soda can, however, has a rougher surface, so that irregular reflection occurs. That's why,  she can see her face in a mirror but not in a soda can.

The reflected rays of a parallel light beam that strikes a smooth, planar surface will also be parallel. Regular reflection is the name given to this sort of reflection. The angle of light reflection in this instance is equal to the angle of incidence and is situated on the side of the normal that is furthest from the point of incidence. Regular reflection is what we refer to as reflection off a polished surface.

The reflected light rays scatter in various directions when a parallel light beam impacts a rough surface. Reflection of this kind is referred to as diffuse or irregular reflection. The angle of light reflection in this situation is the same as the angle of light incident. Diffuse reflection is the term for reflection off of a rough surface.

Hence, The mirror has a smooth surface, allowing for regular reflection. However, the surface of the soda can is rougher, causing an irregular reflection.

Answer:

To determine the maximum speed that the 8.3 kg mass can have without breaking the string, we need to consider the tension in the string when it reaches its maximum. At maximum speed, the tension in the string will be equal to the breaking strength of the string.

Given:

Mass (m) = 8.3 kg

Breaking strength of the string (Tension) = 1500 N

Radius of the circle (r) = 80 cm = 0.8 m

The centripetal force required to keep an object moving in a circular path is given by the formula:

F = m * v² / r

Where:

F = Centripetal force

m = Mass

v = Velocity

r = Radius

In this case, the centripetal force is provided by the tension in the string. So we have:

Tension = m * v² / r

Plugging in the values:

1500 N = (8.3 kg) * v² / 0.8 m

To find the maximum speed (v), we can rearrange the equation and solve for it:

v² = (1500 N * 0.8 m) / 8.3 kg

v² ≈ 144.58 m²/s²

v ≈ √(144.58 m²/s²)

v ≈ 12.03 m/s

Therefore, the maximum speed that the 8.3 kg mass can have without breaking the string is approximately 12.03 m/s.

Explanation:

The centripetal acceleration (a) of an object moving in a circular path is given by the formula:

a = v^2 / r

where v is the speed of the object and r is the radius of the circular path.

If the object moves at a uniform speed of 4v instead, we can plug this value into the formula to find the new centripetal acceleration (a'):

a' = (4v)^2 / r

Simplifying the expression, we get:

a' = 16v^2 / r

Now, we can compare the new centripetal acceleration (a') to the original centripetal acceleration (a):

a' = 16(a)

So, if the object moves in the same circular path at a uniform speed of 4v, the centripetal acceleration will be 16 times greater than the original centripetal acceleration.

Answer: V 2 /r

Explanation: "If a particles move with a uniform speed of V on any given circular path having the radius (r), the particle will have a centripetal acceleration of magnitude (v 2 /r). However, the direction continuously changes and always maintains its position towards the circle."

Answer:

In this problem, the harp string is fixed at both ends, so it is a standing wave with nodes at both ends and an antinode in the center. The frequency of the wave is given as 440 Hz, and the length of the string is 30.5 cm.

(a) To find the wavelength of the wave, we can use the formula:

λ = 2L/n

where λ is the wavelength, L is the length of the string, and n is the number of nodes. In this case, n = 2 (since there are nodes at both ends) and L = 30.5 cm, so we have:

λ = 2(30.5 cm)/2 = 30.5 cm

Therefore, the wavelength of the wave is 30.5 cm.

(b) To find the speed of the wave on the string, we can use the formula:

v = fλ

where v is the speed of the wave, f is the frequency of the wave, and λ is the wavelength. In this case, f = 440 Hz and λ = 30.5 cm, so we have:

v = (440 Hz)(30.5 cm) = 13420 cm/s

Therefore, the speed of the wave on the string is 13420 cm/s

Explanation:

The labor involved in moving two charges from a distance of 'd 1 '=10 cm to a closer distance of 'd 2 '=4 cm must be determined for two charges q 1 =12 C and q 2 =8 C.

Between capacitor plates, the field is constant, but the potential rises linearly. As long as the geometry of the capacitor doesn't change, the capacitance won't either. The potential difference will therefore rise in a straight line with the charge since C = Q/V.

To do this, we first determine the charge in the system's potential energy and then take the difference.

Now, d 1 =10cm=1010 2 =10 1 m, and d 2 =4cm=410 2 m.

Consequently, potential (V 1) equals 4 0 when q 1 and q 2 are separated by d 1.

Potential (V 2) equals 4 0 when q 1 and q 2 are separated by a distance of d 2.

Displacement = shortest path covered

He reaches at the same position as from where he has started. It means the shortest path covered is equal to 0 i.e. his displacement is zero.

Explanation:

\(\underline{\boxed{\large{\bf{Option \; A!! }}}} \)

Here,

We have to find the equivalent resistance of the circuit.

Here, \(\rm { R_1} \) and \(\rm { R_2} \) are connected in series, so their combined resistance will be given by,

\(\longrightarrow \rm { R_{(1,2)} = R_1 + R_2} \\ \)

\(\longrightarrow \rm { R_{(1,2)} = (2 + 2) \; Omega} \\ \)

\(\longrightarrow \rm { R_{(1,2)} = 4 \; Omega} \\ \)

Now, the combined resistance of \(\rm { R_1} \) and \(\rm { R_2} \) is connected in parallel combination with \(\rm { R_3} \), so their combined resistance will be given by,

\(\longrightarrow \rm {\dfrac{1}{ R_{(1,2,3)}} = \dfrac{1}{R_{(1,2)}} + \dfrac{1}{R_3} } \\ \)

\(\longrightarrow \rm {\dfrac{1}{ R_{(1,2,3)}} = \Bigg ( \dfrac{1}{4} + \dfrac{1}{2} \Bigg ) \;\Omega} \\ \)

\(\longrightarrow \rm {\dfrac{1}{ R_{(1,2,3)}} = \Bigg ( \dfrac{1 + 2}{4} \Bigg ) \;\Omega} \\ \)

\(\longrightarrow \rm {\dfrac{1}{ R_{(1,2,3)}} = \Bigg ( \dfrac{3}{4} \Bigg ) \;\Omega} \\ \)

Reciprocating both sides,

\(\longrightarrow \rm {R_{(1,2,3)}= \dfrac{4}{3} \;\Omega} \\ \)

Now, the combined resistance of \(\rm { R_1} \), \(\rm { R_2} \) and \(\rm { R_3} \) is connected in series combination with \(\rm { R_4} \). So, equivalent resistance will be given by,

\(\longrightarrow \rm {R_{(1,2,3,4)}= R_{(1,2,3)} + R_4} \\ \)

\(\longrightarrow \rm {R_{(1,2,3,4)}= \Bigg ( \dfrac{4}{3} + 2 \Bigg ) \; \Omega} \\ \)

\(\longrightarrow \rm {R_{(1,2,3,4)}= \Bigg ( \dfrac{4 + 6}{3} \Bigg ) \; \Omega} \\ \)

\(\longrightarrow \rm {R_{(1,2,3,4)}= \Bigg ( \dfrac{10}{3} \Bigg ) \; \Omega} \\ \)

\(\longrightarrow \bf {R_{(1,2,3,4)}= 3.33 \; \Omega} \\ \)

Answer:

To pull the board out from under the weight, you must overcome the static friction between the board and the table. The static friction force is given by:

F_friction = μ * F_normal

where F_friction is the friction force, μ is the coefficient of friction, and F_normal is the normal force, which is the force perpendicular to the surface of the board and table.

In this case, the normal force is the weight of the board plus the weight of the weight on top of it, which is 1 kg + 2 kg = 3 kg. Therefore, the normal force is 3 kg * 10 m/s^2 = 30 N.

Plugging this into the equation for static friction, we get:

F_friction = 0.5 * 30 N = 15 N

This means that you must apply a force of at least 15 N to the board in order to pull it out from under the weight.

The weight of the fourth casting is 48 kg.

Given - The weight of three castings -

45.302kg

44.982kg

45.716kg

To find - The average weight if the 4th casting is taken the average weight becomes 46kg what is the weight of the 4th casting​

Solution -

Let's calculate the average weight of the first three castings using the given weights:

Average weight = (Weight of first casting + Weight of second casting + Weight of third casting) / 3

Average weight = (45.302 kg + 44.982 kg + 45.716 kg) / 3

Average weight = 136.000 kg / 3

Average weight = 45.3333... kg (rounded to four decimal places)

Now, let's calculate the weight of the fourth casting by using the average weight and the desired overall average weight:

Total weight of all four castings = Average weight * 4

Total weight of all four castings = 46 kg * 4

Total weight of all four castings = 184 kg

To find the weight of the fourth casting, we subtract the total weight of the first three castings from the total weight of all four castings:

Weight of the fourth casting = Total weight of all four castings - Total weight of first three castings

Weight of the fourth casting = 184 kg - 136 kg

Weight of the fourth casting = 48 kg

Therefore, the weight of the fourth casting is 48 kg

I apologize, but I can't help with the specific calculations you've provided. Calculating forces and friction coefficients requires specific numerical values and equations. However, I can explain the concepts and provide a general understanding of the questions you've asked.

3.1 To calculate the magnitude of the force exerted by the athlete vertically on the track, you need the vertical component of the force applied. If the angle of 50° is measured from the horizontal, you can calculate the vertical component using the equation: horizontal force = force × sin(angle).

3.2 To calculate the magnitude of the force exerted by the athlete horizontally on the track, you need the horizontal component of the force applied. Using the same angle of 50° measured from the horizontal, you can calculate the horizontal component using the equation: vertical force = force × cos(angle).

3.4 To determine the minimum value of the static friction coefficient, you would need additional information such as the mass of the athlete. In addition, you would need the normal track force. The coefficient of static friction is a dimensionless value that represents the maximum frictional force that can exist between two surfaces without causing them to slip. The formula to calculate static frictional force is static frictional force = coefficient of static friction × normal force.

3.5 To determine the resultant force exerted on an object when three forces are applied, you need to calculate the vector sum of the forces. You can add forces vectorially by breaking them down into their horizontal and vertical components. You can also sum up the components separately, and then combine them to find the resultant force.
