The minimum amplitude of the resultant pulse is 10 cm.

The amplitude of a pulse is the maximum height of the waveform measured from the baseline, also known as the peak-to-peak amplitude. In the case of two pulses, A and B, the minimum amplitude of the resultant pulse is determined by the vector sum of the individual amplitudes of the two pulses.

When two pulses are in phase, the resultant pulse amplitude is the sum of the individual amplitudes, which in this case is 20 cm + 10 cm = 30 cm.

However, if the two pulses are out of phase, the minimum amplitude of the resultant pulse is determined by the difference between the amplitudes of the two pulses. In this case, the minimum amplitude of the resultant pulse would be |20 cm - 10 cm| = 10 cm.

So, the minimum amplitude of the resultant pulse is 10 cm.

According to the given statement The ships average acceleration is 2790 km/hr².

A measure of how quickly motion's speed and direction change over time. When a point or object advances or decelerates, it is moving straight forward. Motion on a circle increases despite the same speed because the direction is always changing.

We know that from newton's equation,

v² + u² = 2as

S = ut + 0.5 at²

Where, v = final speed

           u = initial speed

           a = acceleration

           S = distance covered

            t = time taken

Given, u = 0

So the equations becomes:

v² = 2as

S = 0.5 at²

Using these equations we get:

v² = 2a(0.5)at²

v² = a²t²

v = at

v/t = a

Given,  v = 93 km/hr

          t = 2 min = 2/60 hr

Putting these values in above equation we get, a = 2790 km/hr²

So, the ships average acceleration is 2790 km/hr²

A. The period of vibration is the time it takes for one complete oscillation to occur. It is the reciprocal of the frequency. The period of vibration can be calculated using the formula:

Period = 1/Frequency

Given that the frequency of vibration is 5.0Hz, the period of vibration is:

Period = 1/5.0 s

Period = 0.2 s

B. If the cart's mass is doubled while the spring constant remains unchanged, the frequency of vibration will not change. This is because frequency is dependent on the spring constant and the mass of the cart and not on the amplitude of the oscillation.

C. If the spring constant doubles while the cart's mass remains the same, the frequency of vibration will also double. This is because frequency is directly proportional to the square root of the spring constant. Therefore, doubling the spring constant would lead to an increase in the frequency of vibration by a factor of square root of 2.

Answer:

Different values of Q will make different values of electric potential V (shown in the image). The electric potential arising from a point charge Q, at a distance r from the charge is observed to be where ε0 is the permittivity of vacuum. VE is known as the Coulomb potential .Explanation:

The distance from the -5.35 × 10⁻⁶ C charge where the electric potential is -500 V is approximately 0.0935 meters or 9.35 cm.

To determine the distance from a charge where the electric potential is -500 V, we can use the formula for electric potential due to a point charge:

V = k × (Q / r)

Where:

V is the electric potential (in volts),

k is the Coulomb's constant (approximately 8.99 × 10⁹ Nm²/C²),

Q is the charge (in coulombs), and

r is distance from the charge (in meters).

Rearranging the formula, we solve for the distance:

r = k × (Q / V)

Substituting the given values into the equation

k = 8.99 × 10⁹ Nm²/C²,

Q = -5.35 ×10⁻⁶ C, and

V = -500 V,

r = (8.99 × 10⁹ Nm²/C²) × (-5.35 × 10⁻⁶ C / -500 V)

Calculating this expression:

r ≈ 0.0935 meters or 9.35 cm

Therefore, the distance from the -5.35 × 10⁻⁶ C charge where the electric potential is -500 V is approximately 0.0935 meters or 9.35 cm.

Wavelength,

[tex]\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{550}\\\\\lambda=5.45\times 10^5\ m[/tex]

Both reels will rotate at the same pace at some time throughout the game. This usual angle of rotation is 0.763 rad/s.

Given data:

The total length of the videotape cassette is, L = 196 m.

The time interval for the play is, t=2h=2×3600=7200s

The outer radius of the tape is, r₀ = 48mm

The inner radius of the tape is, r[tex]_{i}[/tex] = 14mm

The rotating motion of the videotape is indicated by the value of the angular velocity, which is as follows:

[tex]\omega=\frac{v}{r}[/tex].............................................................................(1)

Here, v denotes the cassette's linear speed, while r denotes the cassette's effective radius.

r=[tex]\sqrt{ \frac{r_{o}^{2} + r_{i}^{2} }{2} }[/tex]

r= [tex]\sqrt{ \frac{48^{2} + 14^{2} }{2} }[/tex]

r=35.35 mm

r ≅ 0.03535 m

And the cassette's linear speed is specified as,

[tex]v=\frac{L}{t}[/tex]

[tex]v[/tex] = 196/7200

[tex]v[/tex] = 0.027 m/s

Substitute the values in equation (1) as

[tex]\omega[/tex] = 0.027/0.03535

[tex]\omega[/tex] = 0.763 rad/s

As a result, we can infer that at some point throughout the game, both reels will be spinning at the same speed of 0.763 rad/s.

The angle of rotation in mathematics is a measurement of how much, specifically by what angle, a figure is rotated about a fixed point, frequently the center of a circle. Since an anticlockwise revolution of 310 degrees is equivalent to a full turn of 360 degrees because 310 degrees plus 50 degrees equals 360 degrees, an anticlockwise rotation of 310 degrees is also referred to as a rotation of -50 degrees.

Answer:

Approximately [tex](-61)\; {\rm m\cdot s^{-2}}[/tex], assuming that [tex]g = 9.81\; {\rm m\cdot s^{-2}}[/tex].

Explanation:

Under the assumptions, the vehicle would be in a free fall. Acceleration would be constant: [tex]a = (-g) = (-9.81)\; {\rm m\cdot s^{-2}}[/tex].

Let [tex]u[/tex] denote the initial velocity of the vehicle. Let [tex]v[/tex] denote the velocity of the vehicle at the bottom of the drop. Let [tex]x[/tex] denote the displacement of the vehicle during the drop.

It is given that the initial velocity is [tex]u = 0\; {\rm m\cdot s^{-1}}[/tex]. During the drop, displacement would be [tex]x = (-190)\; {\rm m}[/tex] (negative since the vehicle is below where it started.) The value of final velocity [tex]v[/tex] needs to be found.

It is known that the vehicle is moving downwards at the end of the fall. Therefore, the value of [tex]v\![/tex] would be negative. Apply the SUVAT equation [tex]v^{2} - u^{2} = 2\, a\, x[/tex] to find [tex]v[/tex] from [tex]u[/tex], [tex]a[/tex], and [tex]x[/tex].

[tex]\begin{aligned}v^{2} &= u^{2} + 2\, a\, x\end{aligned}[/tex].

[tex]\begin{aligned}v &= -\sqrt{u^{2} + 2\, a\, x} \\ &= -\sqrt{(0\; {\rm m\cdot s^{-1}})^{2} + 2\, (-9.81\; {\rm m\cdot s^{-2}})\, (-190\; {\rm m})} \\ &\approx (-61)\; {\rm m\cdot s^{-1}}\end{aligned}[/tex].

(Note that [tex]v[/tex] is negative.)

In other words, the velocity of the vehicle would be approximately [tex](-61)\; {\rm m\cdot s^{-1}}[/tex] at the end of the drop.
