a. The speed of the tsunami at ocean depth of 8000 m is 1,019.66 km/h.

b. The speed of the tsunami at ocean depth of 3500 m is 660.75 km/h.

c. The speed of the tsunami at ocean depth of 70 m is 89.66 km/h.

d. The speed of the tsunami at ocean depth of 5 m is 30.625 km/h.

The speed of the tsunami is calculated from method of extrapolation or interpolation as shown below;

8000 m -------- ?

7000 m -------- 943 km/h

4000 m -------- 713 km/h

(8000 - 7000)/(7000 - 4000) = (? - 943)/(943 - 713)

0.3333 =  (? - 943)/230

230(0.3333) = ? - 943

76.66 = ? - 943

? = 1,019.66 km/h

4000 m ---------- 713 km/h

3500 m ---------- ?

2000 m ----------- 504 km/h

(4000 - 3500)/(4000 - 2000) = (713 - ?) / (713 - 504)

0.25 =  (713 - ?) /209

0.25(209) = 713 - ?

52.25 = 713 - ?

? = 660.75 km/h

200 m ------ 159 km/h

70 m --------- ?

50 m ------- 79 km/h

(200 - 70)/(200 - 50) = (159 - ?)/(159 - 79)

0.8667 = 159 - ? / 80

80(0.8667) = 159 - ?

69.336 = 159 - ?

? = 89.66 km/h

50 m ------- 79 km/h

10 m --------- 36 km/h

5 m ---------- ?

(50 - 5)/(50 - 10) = (79 - ?)/(79 - 36)

1.125 = 79 - ?/43

43(1.125) = 79 - ?

48.375 = 79 - ?

? = 30.625 km/h

For component C, a filament lamp, the current-voltage characteristic would be a curve that is not linear. It would exhibit a non-linear increase in current with increasing voltage. At lower voltages, the lamp would have low resistance, but as the voltage increases, the resistance of the filament also increases due to the phenomenon of thermal self-regulation. This leads to a slower increase in current at higher voltages.

For component D, a component that does not obey Ohm's law, the current-voltage characteristic could be any non-linear curve depending on the specific component chosen. Examples of components that do not obey Ohm's law include diodes and transistors.

b. The shape of the characteristic for component C, the filament lamp, can be explained by its construction. A filament lamp consists of a filament made of a resistive material, typically tungsten, which heats up and emits light when an electric current passes through it. As the voltage across the filament increases, the temperature of the filament increases as well, causing its resistance to increase. This increase in resistance results in a slower increase in current with increasing voltage, leading to the characteristic non-linear curve observed.

c. The component chosen for D, which does not obey Ohm's law, could be a diode. A diode is a two-terminal electronic component that allows the current to flow in only one direction. It exhibits a non-linear current-voltage characteristic where it conducts current only when the voltage is above a certain threshold, known as the forward voltage. Below this threshold, the diode has a high resistance and blocks current flow in the reverse direction. The characteristic curve of a diode would show negligible current flow until the forward voltage is reached, after which it exhibits a rapid increase in current with a relatively constant voltage.

Explanation:

if the revolution is in 10 seconds the R,=Total time÷time of the revolution

Answer:

The object will make \(2\frac{1}{2}\)  (2.5) revolutions in 25s.

This indicates that it will revolve through two full revolutions before rotating a third time in the opposite direction.

Explanation:

A rotational period of 10 seconds indicates that an object completes one full rotation every 10 seconds. The object's frequency is therefore 1/10 Hz, or 0.1 Hz. We must apply the calculation to determine how many revolutions it will complete in 25 seconds:

Number of revolutions = frequency x time passed

We are informed that 25 seconds have passed. Using the following formula, we can determine the frequency:

Frequency = 1 / period.

The frequency is because the period is 10 seconds:

Frequency equals 1/10, or 0.1 Hz.

Now we can calculate the number of revolutions using the formula above:

Number of revolutions = (25 s) x (0.1 Hz) = 2.5 revolutions

It takes 10 seconds for the first complete revolution, another 10 seconds for the second full revolution, and 5 seconds for the final half revolution.

In other words, the object starts at its starting location, rotates a whole anticlockwise revolution, another full anticlockwise revolution, and then eventually rotates a further half anticlockwise revolution before returning to its initial position. As a result, the item in this instance rotates in the opposite direction of clockwise.

As a result, in 25 seconds, the object will complete 2.5 revolutions.

Hi there!

Recall the equation for the magnetic field produced by a solenoid:

\(B = \mu_0 ni\)

B = Magnetic field (T)
n = number of turns per unit length (103 turns/m)

i = Current in solenoid (In this instance, changes with respect to time)

Using Faraday's Law:

\(\epsilon = -N\frac{d\Phi_B}{dt}\)

ε = Induced emf (V)
N = Number of loops in coil (15 turns)

\(\frac{d\Phi_B}{dt}\) = Change in magnetic flux with respect to time (Wb/s)

We know that magnetic flux is equal to:
\(\Phi_B = \oint B \cdot dA = B\cdot A\)

Since the cross-sectional area remains constant, we can take it out of the time-derivative. Since the current in the solenoid varies with time, we know that its magnetic field must also vary.

\(\frac{d\Phi_B}{dt} = A * \frac{dB}{dt}\)

Solving for dB/dt, since the solenoid's current is the only thing changing with respect to time:
\(\frac{dB}{dt} = \mu_0 n * \frac{di}{dt}\)

We must first differentiate I(t) using trig and chain derivative rules.

If:
\(f(x) = \alpha sin(\beta t)\\\\f'(x) = (\alpha * \beta) cos(\beta t)\)

Therefore:
\(\frac{di}{dt} = (5 * 120)cos(120t)\\\\\frac{di}{dt} = 600cos(120t)\)

So, dB/dt equals:

\(\frac{dB}{dt} = \mu_0 n\frac{di}{dt}\\\\\frac{dB}{dt} = (4\pi * 10^{-7})(103)(600cos(120t))\\\\\frac{dB}{dt} = 0.0777cos(120t)\)

Now, substituting this expression into the equation for Faraday's Law:
\(\epsilon = -N_{coil} * A * \frac{dB}{dt} \\\\\epsilon = -15 * \pi(0.02^2) * 0.0777cos(120t)\\\\\epsilon = \boxed{-0.001464cos(120t) \text { V}}\)

**For 'A', I used the cross-sectional area of the solenoid because there is no magnetic field produced by the solenoid in the exterior of its opening. Thus, the magnetic field remains confined to an area of A = π(0.02²) = 0.00126 m², which is the value used to calculate the magnetic flux rather than the cross-sectional area of the coil.

**Also, the (-) sign in front of the function of the induced emf simply shows how the induced E-field and consequentially emf opposes the change in the solenoid's current.

The boat must have moved, despite not being seen to move, because its relative position to the dock has changed. This phenomenon is known as relative motion .

Everything is always in motion, but the way we perceive it depends on our frame of reference.

In this scenario, the dock was the frame of reference for the initial position of the boat. When the boat moved to the cove, its position relative to the dock changed, and the dock was no longer an appropriate frame of reference. The boat's motion is now relative to the cove instead.

It is important to note that relative motion depends on the chosen frame of reference. If we were to choose the boat as the frame of reference, then it would be the dock that appears to move, not the boat. This is because motion is always relative to a chosen frame of reference.

In conclusion, the boat must have moved because its position relative to the dock changed. The concept of relative motion reminds us that motion is always relative to a chosen frame of reference, and that the way we perceive motion depends on our chosen frame of reference.

The acceleration due to gravity near the surface of the hypothetical planet is 3.02 m/s².

The formula for acceleration due to gravity is:

g = GM/r² Where, g = acceleration due to gravity G = universal gravitational constant M = mass of the planet r = radius of the planet

In this case, since the mass of the hypothetical planet is the same as that of Earth, we can use the mass of Earth instead of M.

Therefore, g is proportional to 1/r².

So, using the ratio of radii given (1.8), we can write:

r = 1.8 x r Earth, where r Earth is the radius of Earth.

Substituting this value of r in the formula for acceleration due to gravity, we get:

g = GM/(1.8 x r Earth)² = GM/(3.24 x rEarth²) = (1/3.24)GM/rEarth²

We know that the acceleration due to gravity on Earth (g Earth) is 9.8 m/s².

Therefore, we can calculate the acceleration due to gravity on the hypothetical planet (gh) as follows:

gh = (1/3.24) x g Earth = 3.02 m/s²

Thus, the acceleration due to gravity near the surface of the hypothetical planet is 3.02 m/s².

The work done on the box from y=0 to 6.0m is 120 J.

To calculate the work done on the box from y=0 to 6.0m, we need to find the area under the force vs. position graph over that interval.

First, we can find the work done from 0 m to 2 m. Since the force is constant at 40 N over this interval, the work done is simply:

W = F * d = 40 N * 2 m = 80 J

From 2 m to 6 m, the force is constant at -20 N, so the work done is:

W = F * d = (-20) N * 4 m = -80 J

Note that the negative sign indicates that the work is done by the box on the force (since the force is in the opposite direction of the displacement).

Therefore, the total work done on the box from y=0 to 6.0m is:

W_total = 80 J - 80 J = 0 J

The formula for the distance covered by a body moving with an initial velocity u and accelerating at a rate a for a time t is s = ut + ¹/₂at².

To derive the formula for the distance covered by a body moving with an initial velocity u and accelerating at a rate a for a time t, we can use the basic equations of motion.

The first equation of motion states that the final velocity v of a body after time t is given by:

v = u + at

where;

We can rearrange this equation to give:

at = v - u

The second equation of motion states that the distance s covered by a body in time t is given by:

s = ut + ¹/₂at²

Substituting for at from the first equation of motion, we get:

s = ut + ¹/₂(v - u)t

simplifying gives:

s = ut + ¹/₂vt - ¹/₂ut

s = ¹/₂(v + u)t

Substituting the expression for v from the first equation of motion, we have:

s = ¹/₂(u + at + u)t

simplifying gives:

s = ut + ¹/₂at²
