The speed of the water leaving the end of the hose \({0.405 }\frac{ \mathrm{~m}}{ \mathrm{s}} $$\)

As per the given data in question:

Initial diameter of the hose \(D_1=2.80 \mathrm{~cm}$\)

Volume of the bucket \(\mathrm{V}=21.0 \mathrm{~L}=0.021 \mathrm{~m}^3$\)

Time = 1.30 minutes.

The cross-sectional area of the hose is

\(\mathrm{A}_1=\frac{\pi \mathrm{D}_1{ }^2}{4} \\{A}_1=\frac{\pi\left(2.80 \times 10^{-2} \mathrm{~m}\right)^2 }{4}\\{A}_1=6.16 \times 10^{-4} \mathrm{~m}^2$\)

The volume flow rate

\($\dot{V}=\frac{V}{t}\)

\(=\frac{0.021 \mathrm{~m}^3}{1.30 \times 60 \mathrm{~s}}\\=2.50 \times 10^{-4} \frac{\mathrm{~m}^3}{\mathrm{s}$}\)

Speed over water is only required to be used for collision avoidance and not necessarily for navigation. By using speed over ground, a navigator is more aware of the situation than otherwise. For example, if the ship is drifting towards a danger, navigator will know it better if he has speed over ground in radar.

Then, the speed of the water leaving the end of the hose is

\($$\mathrm{v}_1=\frac{\dot{V}}{\mathrm{A}_1} =\frac{\left(2.50 \times 10^{-4} \mathrm{~m}^3 / \mathrm{s}\right)}{\left(6.16 \times 10^{-4} \mathrm{~m}^2\right)} ={0.405 }\frac{ \mathrm{~m}}{ \mathrm{s}} $$\)

In the Hubble Extreme Deep Field, the galaxies seen in the earliest (youngest) stages of their lives are typically the small, faint, and irregularly shaped galaxies.

The Hubble Extreme Deep Field is an image captured by the Hubble Space Telescope that shows a small, seemingly empty patch of sky that contains thousands of galaxies. These galaxies vary greatly in size, shape, and color, and they are located at different distances from us.

Some of these galaxies are very young, while others are much older. However, in general, the galaxies that are seen in the earliest (youngest) stages of their lives tend to be small, faint, and irregularly shaped. This is because they are still in the process of forming and have not yet had the chance to merge with other galaxies or grow in size.
In conclusion, the small, faint, and irregularly shaped galaxies are the ones that are typically seen in the earliest (youngest) stages of their lives in the Hubble Extreme Deep Field. As these galaxies evolve and grow, they may become more structured and take on different shapes and sizes.

The period of oscillation of a spider hanging on a silk thread, tapped once every second, is one second.

What is the period of oscillation of a spider hanging on a silk thread when tapped once every second?

The time it takes for one complete up-and-down motion of the spider on the silk thread is called the period of oscillation, denoted by T. We know from the problem statement that the spider has the largest amplitude on its bungee cord when tapped exactly once every second.

If the tapping is done exactly once every second, then the spider is experiencing a periodic force with a frequency of 1 Hz. In this case, the period of oscillation T is equal to the reciprocal of the frequency, which is:

T = 1/f = 1/1 Hz = 1 second

Therefore, the spider completes one full oscillation (i.e., up-and-down motion) every second.

To solve the question, we have to apply the concept of projectile motion. Given the following data: Height of the plane from the ground = 180 m. Speed of the plane = 170 m/s.

Using the concept of projectile motion, we can find the distance at which the package should be dropped. We know that the horizontal distance (x) is given by the equation:

x = vt Where v = velocity t = time.

Taking the vertical motion, we have the height from the ground as 180 m and acceleration due to gravity as -9.8 m/s²

Using the kinematic equations, we can find the time at which the package should be dropped.Initial velocity (u) = 0 m/s

Final velocity (v) = ?Acceleration (a) = -9.8 m/s²Time (t) = ?Height (s) = 180 m. We use the equation:v² = u² + 2as

Where,u = initial velocityv = final velocitya = acceleration due to gravity = height from the ground

Substituting the given values,v² = 0 + 2(-9.8)(180)∴ v = 84.68 m/s

Now, we can calculate the time taken to reach the ground using the equation:s = ut + 1/2 at²

Where,u = 0 m/st = ?a = -9.8 m/s²s = 180 mt = √2s/a∴ t = √(2 × 180/9.8)≈ 6.79 sThe total distance travelled by the package in the horizontal direction would be:x = vt = 170 × 6.79≈ 1156.3 m

Therefore, the package should be dropped 1156.3 m from the target so that it would reach the scientists on the glacier. The concept of projectile motion involves the motion of an object thrown or dropped from a certain height or launched at an angle.

The motion of the object is influenced by two forces: the horizontal force and the vertical force. The horizontal force is constant throughout the motion, whereas the vertical force varies due to the acceleration due to gravity.

Projectile motion is often observed in games such as basketball, cricket, and football. It is also used in real-life applications such as calculating the distance of a missile launched or finding the landing point of a satellite.

In conclusion, the given problem of finding the distance at which a package should be dropped can be solved using the concept of projectile motion. The total distance travelled by the package is 1156.3 m from the target. The concept of projectile motion has many real-life applications and is used in various fields such as physics, engineering, and sports.

The direction of this current's magnetic force on an electron that is moving perpendicular to the page and outward from it on the left side of the wire is downward.

What is Magnetic force?

The force exerted by a magnetic field on a moving charged particle is known as a magnetic force. It is described by the formula F = q(v x B), where F is the magnetic force, q is the particle's charge, v is the particle's velocity, and B is the magnetic field.

The right-hand rule states that when a wire-carrying current is held in the right hand with the thumb pointing in the direction of the current, the fingers will curl in the direction of the magnetic field lines created by the current.

The magnetic field lines will create clockwise circles around the wire because, in this instance, the current flows from the top of the page downward.

Now imagine an electron on the left side of the wire traveling perpendicular to the page. The electron will experience a magnetic force since it travels in a direction perpendicular to both the magnetic field and the current.

We can use the left-hand rule for a negative charge to determine the direction of this force. If the left hand is held with the fingers pointing toward the magnetic field and the thumb pointing toward the electron's velocity, the palm will face the order of the force on the electron.

The thumb points to the left because the electron leaves to the left. The fingers curl because the magnetic field lines go clockwise around the wire. Therefore, the magnetic force acting on the electron is directed downward because the palm is facing downward.

Therefore, the magnetic pull exerted by this current on an electron traveling outward and perpendicular to the page on the wire's left side is directed downward.

It takes around 100,000 years for photons to emerge from the Sun's core to the outside.

Photons are the elementary particles that make up light. In the Sun's core, nuclear fusion reactions produce high-energy photons, which are continually absorbed and re-emitted by the atoms in the dense plasma. These photons interact with other particles in the plasma, making their journey to the surface a slow and indirect process.

It takes a photon around 100,000 years to travel from the Sun's core to the outside. This is due to the high density and opacity of the Sun's interior, which causes the photons to undergo a random walk through the plasma, bouncing off atoms and being absorbed and re-emitted many times before they finally reach the surface. Once the photons reach the surface, they can escape into space and travel to Earth in just over 8 minutes. The process of photons escaping from the Sun's core and eventually reaching Earth is a crucial part of the solar energy that sustains life on our planet.

Answer:

The box with a mass of 10 kilograms would have a greater amount of potential energy than the box with a mass of 4 kilograms.

Explanation:

Potential energy can be defined as an energy possessed by an object or body due to its position.

Mathematically, potential energy is given by the formula;

\( P.E = mgh\)

Where,

P.E represents potential energy measured in Joules.

m represents the mass of an object.

g represents acceleration due to gravity measured in meters per seconds square.

h represents the height measured in meters.

Let's assume the height is 5 meters.

Acceleration due to gravity, g = 10 m/s²

For box with mass of 10 kg

\( P.E = 10*10*5\)

P.E = 500 Joules.

For box with mass of 4 kg;

\( P.E = 4*10*5\)

P.E = 200 Joules.

Hence, the box with a mass of 10 kilograms would have a greater amount of potential energy than the box with a mass of 4 kilograms.

Question

Arjun and his son Arav were standing ‘x’ m away from each other. They are equidistant (Y m) from a vertical cliff. Arjun burst a balloon and Arav heard the direct sound 0.5 seconds later and the echo after 2 seconds. If the speed of sound in air is 340m/s ,calculate

i. the distance between Arjun and Arav

ii. the distance between the cliff and Arjun

The parameters given are;

The time for the sound to reach Arav, \(t_D\) = 0.5 s

Time for the echo to echo to reach Arav, \(t_E\) = 2 s

The distance between Arjun and Arav = \(D_D\)

The distance between Arav and the cliff = \(D_E\)

The speed of sound in air, s = 340 m/s

The formula for speed, s, is \(s = \dfrac{Distance, D}{Time, t}\), therefore;

\(s = \dfrac{D_D}{t_D} = \dfrac{D_D}{0.5} = 340\)

\(D_D\) = 0.5 s × 340 m/s = 170 m

The distance between Arjun and Arav = 170 m

ii. Since Arav hears the direct sound before the echo, he is closer to the cliff than Arjun, therefore, we have;

\(s = \dfrac{D_E}{t_E} = \dfrac{D_E}{2} = 340\)

\(D_E\) = 2 s × 340 m/s = 680 m

Therefore, the distance between Arav and the cliff = 680 m

Which gives the distance between the cliff and Arjun, \(D_{cliff}\) = The distance between Arav and the cliff + The distance between Arjun and Arav

\(D_{cliff}\) = 680 + 170 = 850 m.

The car will have traveled through an angle of approximately 119.7 degrees when the magnitude of its total acceleration is 2.6 m/s^2.

What is the angle of approximate calculation?

The magnitude of the total acceleration of a car on a curved path can be given by:

a = √(at^2 + ac^2)

where at is the tangential acceleration (1.3 m/s^2), and ac is the centripetal acceleration, which is given by:

ac = v^2 / r

where v is the velocity of the car and r is the radius of the curve (130 m).

Setting a = 2.6 m/s^2, we can solve for v:

v = √(r * a^2 - at^2) = √(130 * 2.6^2 - 1.3^2) = 27.47 m/s

The angle through which the car will have traveled can be found using the equation for the arc length s:

s = r * θ

where θ is the angle in radians. Substituting the values for v and t into the equation for s, we can solve for θ:

θ = s / r = v * t / r

Since the car started from rest, t can be found from the equation for acceleration:

at = v / t

t = v / at = 27.47 / 1.3 = 21.06 s

Finally, substituting t into the equation for θ, we get:

θ = v * t / r = 27.47 * 21.06 / 130 = 2.07 radians = 119.7 degrees

Spiral galaxies are classified based on spiral arm tightness, bulge size, and amount of gas and dust present. This allows astronomers to categorize them into subtypes such as Sa, Sb, and Sc.

The classification of spiral galaxies is based on three properties:

1. Spiral arm tightness: This refers to how tightly wound the spiral arms are around the galaxy's center. Galaxies with more tightly wound arms are classified as "Sa," while those with more loosely wound arms are classified as "Sc."

2. Bulge size: The central bulge of a spiral galaxy can vary in size. Larger bulges are typically found in early-type spiral galaxies (such as Sa), while smaller bulges are found in late-type spiral galaxies (like Sc).

3. Amount of gas and dust: The presence and distribution of gas and dust within a spiral galaxy also play a role in its classification. Early-type spiral galaxies generally have less gas and dust compared to late-type spiral galaxies.

By considering these three properties, astronomers can classify spiral galaxies into various subtypes (such as Sa, Sb, and Sc) within the broader spiral galaxy category.

t₁ = t₂  

s₁ = initial distance

s₂ = final distance

t₁ = initial time

t₂ = final time

Hence, the time does it take the weight to hit the ground = 2.4 s

The initial distance (s₁) = 200 m, and the pilot does a run at the same height but twice the speed.
