True, due to the protective nature of the ozone layer and the absorption of UV radiation, conducting ultraviolet astronomy from space is necessary to gather accurate and detailed data about celestial objects and phenomena emitting UV light.

The ozone layer plays a crucial role in protecting the Earth's surface from harmful ultraviolet (UV) radiation. It absorbs a significant portion of the Sun's UV rays, preventing them from reaching the surface and potentially causing damage to living organisms.

As a result, to observe and study ultraviolet astronomy, which involves the detection and analysis of celestial objects and phenomena emitting UV radiation, observations must be conducted from space. By observing from space, astronomers can bypass the Earth's atmosphere, including the ozone layer, and directly capture the UV light from celestial sources.

UV astronomy satellites and telescopes, such as the Hubble Space Telescope and the International Ultraviolet Explorer (IUE), have been specifically designed and deployed to conduct observations in the ultraviolet spectrum. These instruments are situated above the Earth's atmosphere, enabling them to capture and analyze UV radiation without interference from atmospheric absorption.

There are various types of electromagnetic radiation all around us, including radio waves, microwaves, X-rays, and gamma rays. The electromagnetic spectrum, which spans a wide range of wavelengths, includes visible light, which is also a type of electromagnetic energy.

In terms of reflection, refraction, diffraction, and interference, electromagnetic radiation shares characteristics with other types of waves. Additionally, its wavelength or the frequency with which it changes over time can be used to describe it. However, electromagnetic radiation also exhibits particle-like characteristics in addition to those connected to wave motion. It is quantized in that, at a particular frequency, its energy is represented by an integer multiplied by h, where h is the so-called Planck's constant, a basic constant of nature. A photon is an electromagnetic energy quantum. A stream of photons, with photon energy exactly proportional to frequency, can be thought of as electromagnetic radiation, including visible light.

The polygon in question is a regular pentagon.

A regular polygon is a polygon with all sides and angles equal. In this case, the polygon is equiangular, meaning all of its angles are equal.
Let's break down the information given in the question. The measure of an interior angle of the polygon is said to exceed four times the measure of one of its exterior angles by 30. This can be written as:
Interior angle = 4 * Exterior angle + 30
We know that the sum of the exterior angles of any polygon is always 360 degrees. Therefore, we can write:
360 degrees = n * Exterior angle
where n is the number of sides in the polygon.
Since we are looking for a regular polygon, all the exterior angles are equal. So, we can divide 360 degrees by the number of sides to find the measure of each exterior angle.
Now, substituting this value in the equation for the interior angle, we can solve for the number of sides (n).
After solving the equation, we find that n is equal to 5.

The force that keeps the arms of the Milky Way spinning around its center is primarily gravitational force.

The Milky Way is a spiral galaxy, and like other galaxies, it consists of stars, gas, dust, and other celestial objects. These components collectively exert gravitational forces on each other.

In the case of the Milky Way, the combined gravitational force from all its mass components acts as a centripetal force, pulling the stars and gas inwards toward the galactic center. This force allows the stars and gas in the galactic disk to maintain their orbits around the center.

The rotation of the Milky Way is governed by the balance between the inward gravitational force and the outward centrifugal force caused by the rotation itself. As the galaxy rotates, the centrifugal force tends to pull the stars and gas outward, while the gravitational force pulls them inward. When these forces balance out, the objects within the galaxy's arms can maintain their circular or nearly circular orbits.

It's important to note that the concept of "arms" in a spiral galaxy is a pattern formed by the distribution of stars and gas, and not physical structures like solid objects. The gravitational force is responsible for shaping and maintaining these patterns as the galaxy rotates

The kinetic energy of the wheel, with an angular speed of 3000rev/min if the radius gyration of the wheel is 12cm,  is approximately 24,568.15 Joules.

To determine the kinetic energy of the wheel, we'll need to use the following formula:

Kinetic Energy (KE) = 0.5 * I * ω²

Where I is the moment of inertia, and ω is the angular speed in radians per second.

First, we need to convert the angular speed from rev/min to radians per second:

ω = 3000 rev/min * (2π radians/rev) * (1 min/60 sec) = 314.16 radians/sec

Next, we can calculate the moment of inertia using the mass (35 kg) and radius of gyration (0.12 m):

I = m * k² = 35 kg * (0.12 m)² = 0.504 kg*m²

Finally, we can find the kinetic energy:

KE = 0.5 * 0.504 kg*m² * (314.16 radians/sec)² = 24,568.15 J

The kinetic energy of the wheel is approximately 24,568.15 Joules.

Answer:

60.3375 m/ per sec

Explanation:

first multiply 1609 (the amount of meters in a mile) by 135( the total number of miles). this brings you to conclude there are a total of 217,215 meters in 135 miles.

So 135 mph = 217,215 meters per hour.

From here I took a simple route so as to not need a calculator.

217,215 meters = 60mins. (divide both sides by 2)

108,607.5 = 30mins. (divide both sides by 2)

54,303.75 = 15mins. (divide both sides by 15)

3620.25 = 1min

3620.25 = 60secs. (divide both sides by 60)

60.3375 = 1sec

60.3375 meters per second = 135miles per hr.

This is an exercise in Rectilinear Uniformly Varied Motion (MRUV) is a type of motion in which an object moves in a straight line and experiences changes in its velocity at a constant rate. In this type of motion, the acceleration of the object remains constant over time.

The distinctive feature of the MRUV is that the velocity of the object changes uniformly, that is, its velocity increases or decreases by a constant amount in each unit of time. If the object experiences a positive acceleration, its velocity increases with time. On the other hand, if the object experiences a negative acceleration, its speed decreases.

In an MRUV, constant acceleration has a direct impact on displacement and the time it takes for the object to reach a certain speed. Also, the direction of the acceleration determines whether the object is accelerating or decelerating relative to its initial motion.

This type of movement is found in various situations of daily life, such as the launch of an object upwards and its subsequent fall, the movement of cars on a road with acceleration or braking, or even the study of bodies in free fall.

Vf = V₀ + a × t

Where:

In this case, the initial velocity (vi) is 1 m/s, the acceleration (a) is -1 m/s^2 (negative because it indicates deceleration), and the time (t) is 4 seconds.

Substituting these values into the formula, we get:

Vf = V₀ + a × t

Vf = 1 m/s + (-1 m/s²) × 4 s

Vf = 1 m/s - 4 m/s

Vf = -3 m/s

The fraction of the iceberg that is above the surface of the water is 8.3 %.

The specific gravity of any material is defined as the ratio of the density of the material to the density of water.

Mathematically, the formula for specific gravity of materials =

Specific gravity of the seawater = 1.025

The fraction of the iceberg submerged in the seawater =

= 0.917 = 0.917 x 100 %

The fraction of the iceberg that is above the surface of the water =

= 1 - 0.917
