If the fundamental frequency of the harmonic is 7 Hz, the frequency at which it is created depends on the harmonic being referred to.

Frequency of harmonics

If the fundamental frequency of a harmonic is 7 Hz, then the frequency at which the harmonic is created depends on the harmonic series being used.

The frequency of the nth harmonic in a harmonic series is equal to n times the fundamental frequency. Therefore, the first five harmonics of a harmonic series with a fundamental frequency of 7 Hz would be:

First harmonic (fundamental): 7 Hz

Second harmonic: 2 x 7 Hz = 14 Hz

Third harmonic: 3 x 7 Hz = 21 Hz

Fourth harmonic: 4 x 7 Hz = 28 Hz

Fifth harmonic: 5 x 7 Hz = 35 Hz

So, the frequency at which the harmonic with a fundamental frequency of 7 Hz is created depends on which harmonic is being referred to.

The final speed of the astronaut in this scenario will be 1 m/s toward the shuttle.

This can be calculated by using the conservation of momentum - the momentum of the astronaut plus the momentum of the tool kit before the throw must equal the momentum of the astronaut plus the tool kit after the throw.

Momentum before the throw = (80 kg)(2 m/s) + (20 kg)(0 m/s) = (160 kg m/s) Momentum after the throw = (80 kg)(v) + (20 kg)(6 m/s)

Solving for v gives us v = 1 m/s. Therefore, the astronaut's final speed is 1 m/s toward the shuttle.

Answer:

9.23m

Explanation:

Max height = u²sin²theta/2g

u is the speed = 34.7m/s

theta is the angle of elevation = 33°

g is the acceleration due to gravity = 9.8m/s²

Substitute into the formula

Max height = 24.7²sin²33/2(9.8)

Max height = 610.09sin²33/2(9.8)

Max height = 610.09(0.29663)/19.6

Max height = 180.97/19.6

Max Height = 9.23m

Hence the max height the football reaches during flight is 9.23m

Explanation:

According to the question the tension in each wire is 1.96 N.

Tension is a term that describes the psychological and physical state of a person or system in which there is a high degree of stress, uncertainty, and anxiety. It is often associated with conflict and is often experienced when individuals or groups feel threatened or constrained in some way. Tension can be experienced in a variety of different contexts, from interpersonal relationships to the workplace. It can result from a variety of different factors, including a lack of communication, conflicting goals or expectations, and unmet needs.

The body is in equilibrium when the sum of all forces acting on it is equal to zero. In this case, the forces acting on the metal tube are the two wires and the weight of the tube due to gravity.

The tension in each wire is equal to the weight of the tube divided by the length of the tube. This is because the tube is suspended horizontally, so the forces in each wire must be equal in order to keep the tube in equilibrium.

Therefore, the tension in each wire is:

T = (9 kg × 9.8 m/s2) / (5 cm × 0.01 m)

= 1.96 N

Therefore, the tension in each wire is 1.96 N.

The magnitude of the electric flux through the sheet is 4.05 N m² C⁻¹ (Option E).

The electric flux through a surface is given by the product of the electric field strength and the area of the surface projected perpendicular to the electric field.

In this case, the electric field strength is 18 N C⁻¹, and the area of the sheet projected perpendicular to the electric field is 0.450 m²

(since the normal to the sheet makes an angle of 60° with the electric field). Multiplying these values gives the electric flux:

Electric flux = Electric field strength × Area

Electric flux = 18 N C⁻¹ × 0.450 m²

Electric flux = 8.1 N m² C⁻¹

In summary, the magnitude of the electric flux through the sheet is 4.05 N m² C⁻¹. This value is obtained by multiplying the given electric field strength by the projected area of the sheet perpendicular to the electric field.

The angle of 60° is taken into account to determine the effective area for calculating the flux.(Option E).

Given :

Solenoid 2 has twice the radius and six times the number of turns per unit length as solenoid 1.

To Find :

The ratio of the magnetic field in the interior of 2 to that in the interior of 1.

Solution :

We know, magnetic field in the interior of a solenoid is given by :

Let, length of solenoid 2 is L.

Therefore, length of solenoid 1 is 6L.

\(B_a=\dfrac{\mu (6n)i}{L}\\\\B_b = \dfrac{\mu n i}{L}\)

Dividing \(B_a\) by \(B_b\) :

\(\dfrac{B_a}{B_b}=\dfrac{\dfrac{\mu (6n)i}{L}}{\dfrac{\mu n i}{L}}\\\\\dfrac{B_a}{B_b}=6\)

- The resistance of the first resistor (R₁) is 12 Ω.

- The electromotive force (EMF) of the battery is 18 V.

- The internal resistance of the battery is 12 Ω.

To solve the given problem, we can apply Kirchhoff's laws and Ohm's law to determine the resistance of the first resistor (R₁) and the electromotive force (EMF) and internal resistance of the battery.

Let's start by calculating the resistance of the first resistor (R₁):

1. Apply Ohm's law to find the voltage drop across the external circuit:

  V = I * R

  V = 1 A * 6 Ω

  V = 6 V

2. The voltage drop across the external circuit is equal to the EMF minus the voltage drop across the internal resistance of the battery:

  V = E - Ir

  6 V = E - (1 A * r)   (where r is the internal resistance of the battery)

3. We also know that the EMF of the battery is the sum of the voltage drops across each cell in the battery:

  E = 6 cells * 3 V/cell

  E = 18 V

4. Substitute the value of E in the equation from step 2:

  6 V = 18 V - r

  r = 12 Ω

Therefore, the resistance of the first resistor (R₁) is 12 Ω.

The only force acting on the car is the frictional force f and since friction is a force that is always directed opposite to the direction of motion, it will have a negative sign. Therefore, we can write Newton's 2nd law as

\(x:\;\;\;\;F_{net} = -f = -\mu N = ma\) (1)

\(y:\;\;\;\;F_{net} = N - mg = 0\) (2)

Substituting Eqn(2) into Eqn(1), we get

\(\Rightarrow a = -\mu g\) (3)

To find the stopping distance x, we are going to use the equation

\(v^2 = v_0^2 + 2ax\)

Initially, the car was moving at \(v_0 = 27\:\text{m/s}.\) When it stopped, its final velocity \(v\) is zero. Using these, as well as Eqn(3) on the equation for v^2, we find that

\(0 = v_0^2 + 2(-\mu g)x \Rightarrow 0 = v_0^2 - 2\mu gx\)

or solving for x,

\(x = \dfrac{v_0^2}{2\mu g} = \dfrac{(27\:\text{m/s})^2}{2(0.85)(9.8\:\text{m/s}^2)}\)

Pressure on the hydraulic system is expressed as;

Pressure = Force/Area

Given

Force on the fluid = 400N

Area = 0.001m²

Pressure in the fluid = 400/0.001

Pressure in the fluid = 400,000N/m²

1N/m² = 0.001kPa

400,000N/m² = x

x = 400,000 × 0.001

x = 400kPa

Hence the pressure in kPa is 400kPa

b) Using the formula;

Pa = Pb

Fa/Aa = Fb/Ab

Pa = Fb/Ab

Fb = PaAb

Fb = 400,000(0.2)

Fb = 80,000N

Hence the magnitude of the force exerted on the load bearing piston by the hydraulic fluid is 80,000N

24 volts is the voltage drop across each of the resistors in the parallel configuration.

When resistors are connected in parallel, they share the same voltage across them. Therefore, the voltage drop across each resistor in this scenario would be the same.

Given:

Power supply voltage (V) = 12 V

Resistance of each resistor (R) = 30 Ω

Since the resistors are in parallel, the total resistance (R_total) can be calculated using the formula:

1/R_total = 1/R1 + 1/R2

Substituting the values:

1/R_total = 1/30 Ω + 1/30 Ω

1/R_total = 2/30 Ω

R_total = 15 Ω

Now, we can find the current flowing through the resistors (I) using Ohm's Law:

I = V / R_total

I = 12 V / 15 Ω

I = 0.8 A

Since the voltage drop across each resistor is the same, we can find it using Ohm's Law:

V_drop = I * R

V_drop = 0.8 A * 30 Ω

V_drop = 24 V

Therefore, the voltage drop across each of the resistors in the parallel configuration is 24 volts.

It is the component of the normal force that acts perpendicular to the direction of motion. The normal force is the force exerted by a surface on an object that is in contact with it. It acts perpendicular to the surface and helps to support the weight of the object. In the case of a train rounding a banked track, the normal force acts perpendicular to the surface of the track and helps to keep the train from sliding off the track.

Explanation: i just took my test and this was correct!

Answer: Our day-to-day life highly relates to physics.

Explanation: We know that in physics there are many laws such as gravitational laws, laws of friction, and inertia.For example

The spring constant, symbolized k, is a proportionality constant that shows the relationship between the force applied to a spring and the amount of stretch or compression it undergoes in response.

In simple terms, the spring constant relates the force that is required to extend or compress a spring by a certain distance.

This is what is known as Hooke's Law, named after the scientist Robert Hooke.

According to Hooke's Law, the force required to compress or stretch a spring is directly proportional to the distance that the spring has been compressed or stretched.

Hooke's law can be expressed mathematically as: F = -kx, where F is the force being applied to the spring, x is the distance the spring is stretched or compressed from its equilibrium position, and k is the spring constant.

The negative sign in the equation indicates that the direction of the force is opposite to the direction of displacement of the spring.

The units of the spring constant depend on the units of the force and displacement used in the equation.

In SI units, the spring constant is measured in Newtons per meter (N/m).
