Find the average velocity if the takeoff velocity of an airplane on a runway is 300 km/hr with an acceleration of 1 m/s2 . A) 30 sec B) 41.7 sec C) 72.2 sec D) 83.33 sec

(A) To determine the current in the secondary coil, we need to use the equation P = IV, where P is the power (490W), I is current, and V is the voltage (17kV). Solving for I, we get:

I = P/V = 490W/17kV = 0.029A

Therefore, the current in the secondary coil is 0.029A.

(B) To find the current in the primary coil, we can use the equation V = NΔΦ/Δt, where V is the voltage (120V for a normal household outlet), N is the number of turns in the primary coil (500), ΔΦ is the change in magnetic flux, and Δt is the time. We can assume that the frequency of the AC output is 60Hz, so Δt = 1/60s.

Since the transformer is running at full power, we can assume that the magnetic flux is constant and therefore ΔΦ = 0.

Thus, we can simplify the equation to V = NΔΦ/Δt = 500 x 0/ (1/60) = 0.

This means that there is no current flowing in the primary coil, as the transformer is not drawing any power from the household outlet.

The Wolfe Creek object is believed to be a meteorite that impacted the Earth in the remote Wolfe Creek Crater in Western Australia. When the object hit, it released a tremendous amount of energy, causing an explosion equivalent to a nuclear blast.

This explosion was powerful enough to hurl everything within the crater out into the surrounding countryside.

To understand why the impact released so much energy, we can look at the physics involved.

When a fast-moving object like a meteorite collides with the Earth's atmosphere, it experiences a tremendous amount of friction and compression.

This causes the object to heat up and eventually explode upon impact.

The energy released during the explosion is equivalent to a nuclear blast because both involve the rapid release of a massive amount of energy.

In the case of a nuclear blast, this energy is released through a nuclear reaction.

In the case of the Wolfe Creek object impact, the energy is released through the explosive force of the impact itself.

The impact created a crater, which is a bowl-shaped depression in the ground.

The explosion was so powerful that it launched debris from within the crater outward, scattering it across the surrounding countryside.

This is similar to what happens during a volcanic eruption, where material from within the volcano is expelled and distributed over the surrounding area.

The Wolfe Creek object impact released a tremendous amount of energy, causing an explosion equivalent to a nuclear blast.

a. John Glenn would have weighed 160 N if his Mercury spacecraft had (hypothetically) remained at twice the distance from the center of Earth

b. An astronaut is never truly weightless because the earth still exerts a gravitational pull on the astronaut since the spaceships are not at an infinite distance from the earth who in space is actually experiencing free fall due to gravity.

From Newton's law of Universal gravitation:

From the question, the distance between the spacecraft and the center of the earth is twice the distance on the earth's surface.

All other values remained constant, therefore, only the change in distance will affect the force.

Weight or force of gravity on John on the earth's surface is given as:

The equation for calculating the new force or weight, Fₓ will simply be;

since d = 2

Fₓ = 640 / 2²

Fₓ = 160 N

Therefore, John Glenn would have weighed 160 N if his Mercury spacecraft had (hypothetically) remained at twice the distance from the center of Earth.

b. The spacecraft carrying astronauts orbit the earth at very high speeds. So astronauts even though experiencing free fall due to the gravitational force of the earth, never really fall onto the  earth's surface.

A real root of the equation f(x) = x^2 - 2x - 5 = 0, found using the bisection method in five stages, is approximately x = -0.046875. To find a real root of the equation f(x) = x^2 - 2x - 5 = 0 using the bisection method, we can start by identifying an interval [a, b] that contains the root. Let's choose the interval [-3, 0], where f(a) = f(-3) = 4 and f(b) = f(0) = -5. Since f(a) and f(b) have opposite signs, there must be a root within this interval.

Stage 1:

- Start with interval [a, b] = [-3, 0]

- Calculate the midpoint c = (a + b) / 2 = (-3 + 0) / 2 = -1.5

- Evaluate f(c) = (-1.5)^2 - 2(-1.5) - 5 = -0.25

- Since f(c) has the same sign as f(a), replace a with c: [a, b] = [-1.5, 0]

Stage 2:

- Calculate the new midpoint c = (a + b) / 2 = (-1.5 + 0) / 2 = -0.75

- Evaluate f(c) = (-0.75)^2 - 2(-0.75) - 5 = -4.4375

- Since f(c) has the same sign as f(a), replace a with c: [a, b] = [-0.75, 0]

Stage 3:

- Calculate the new midpoint c = (a + b) / 2 = (-0.75 + 0) / 2 = -0.375

- Evaluate f(c) = (-0.375)^2 - 2(-0.375) - 5 = -2.7461

- Since f(c) has the same sign as f(a), replace a with c: [a, b] = [-0.375, 0]

Stage 4:

- Calculate the new midpoint c = (a + b) / 2 = (-0.375 + 0) / 2 = -0.1875

- Evaluate f(c) = (-0.1875)^2 - 2(-0.1875) - 5 = -1.2217

- Since f(c) has the same sign as f(a), replace a with c: [a, b] = [-0.1875, 0]

Stage 5:

- Calculate the new midpoint c = (a + b) / 2 = (-0.1875 + 0) / 2 = -0.09375

- Evaluate f(c) = (-0.09375)^2 - 2(-0.09375) - 5 = -0.6104

- Since f(c) has the same sign as f(a), replace a with c: [a, b] = [-0.09375, 0]

After five stages, the interval [a, b] has become [-0.09375, 0]. Since the interval is small, we can approximate the root as the midpoint of this interval:

Root ≈ (a + b) / 2 = (-0.09375 + 0) / 2 = -0.046875

Therefore, a real root of the equation f(x) = x^2 - 2x - 5 = 0, found using the bisection method in five stages, is approximately x = -0.046875.

The work done in stretching the spring from its natural length to 10 inches beyond its natural length is 112 lb·in.

The work done in stretching a spring is given by the formula:

\(\[ W = \frac{1}{2} k (x_f^2 - x_i^2) \]\)

In this case, the spring is stretched 4 inches beyond its natural length, so the initial displacement is 4 inches. The force required to hold the spring at this displacement is 16 lb. We can use Hooke's Law to find the spring constant:

\(\[ k = \frac{F}{x_i} = \frac{16 \, \text{lb}}{4 \, \text{in}} = 4 \, \text{lb/in} \]\)

Now, we can calculate the work done in stretching the spring to 10 inches beyond its natural length:

The work done by the gravitational force in equalizing the levels when the two vessels are connected is 0.03733 J.

The work done by the gravitational force in equalizing the levels when the two vessels are connected can be found using the formula:

Work = force x distance

where force is the weight of the liquid and distance is the difference in height between the two vessels. The weight of the liquid in each vessel can be calculated as the product of the volume and density of the liquid, and the difference in height can be found by subtracting the height of the lower vessel from the height of the higher vessel.

The weight of the liquid in each vessel can be calculated as:

Weight = density x volume x gravity

where density is 1.17 g/cm³, volume is the product of the area of the base and height of the liquid, and gravity is 9.81 m/s².

For the vessel with a liquid height of 0.906 m, the volume can be calculated as:

Volume = area of base x height of liquid = 2.94 cm² x 0.906 m = 0.00266244 m³

So, the weight of the liquid in this vessel is:

Weight = 1.17 g/cm³ x 0.00266244 m³ x 9.81 m/s² = 0.031105 N

Similarly, for the vessel with a liquid height of 1.50 m, the volume can be calculated as:

Volume = area of base x height of liquid = 2.94 cm² x 1.50 m = 0.00441 m³

So, the weight of the liquid in this vessel is:

Weight = 1.17 g/cm³ x 0.00441 m³ x 9.81 m/s² = 0.051456 N

The difference in height between the two vessels is:

Height difference = 1.50 m - 0.906 m = 0.594 m

Therefore, the work done by the gravitational force in equalizing the levels when the two vessels are connected is:

Work = force x distance = (0.051456 N + 0.031105 N) x 0.594 m = 0.03733 J

The frequency of radio waves is 1.667 GHz

One portion of the same wave front travels 1.260 mm farther than the other before the two signals are combined.

There are two conditions for interference either constructive or destructive.

For constructive interference , the path difference is n times of wavelength and for destructive interference, the path difference is (n+1/2) times of wavelength

We can find wavelength in this case as follows :

\(\lambda=\dfrac{c}{f}\\\\\lambda=\dfrac{3\times 10^8}{1.667\times 10^9}\\\\\lambda=0.1799\ m\)

If we divide path difference by wavelength,

\(\dfrac{\delta}{\lambda} =\dfrac{1.26}{0.1799}\\\\\dfrac{\delta}{\lambda} =7\\\\\delta =7\lambda\)

It means that the path difference is 7 times of the wavelength. it means the two waves combine constructively and the value of m for the path difference between the two signals is 7.
