Answer:

What we see in the sky

Where are they in the general context of the overview of the Universe?

With the naked eye, the main astronomical objects we can see are the Sun, the Moon, the stars, and some of the planets

All of the stars we see are in the Milky Way galaxy, most of them relatively close to the Sun.

The stars we see in the sky come in a range of brightnesses, partly because stars come in different intrinsic brightnesses, and partly because some are closer than others.

When we look at an astronomical object ``by eye'', we can't tell just by looking how far away it is (because not all objects have the same intrinsic brightness). All we can see is what direction it is in.

As a result, when looking ``by eye'', the positions of stars on the sky are described by their direction only; you can imagine that the sky is a big sphere with astronomical objects located at different positions on it. This is called the celestial sphere

The positions of the stars can be described with a sort of astronomical longitude and latitude, called right ascension and declination.

Constellations are patterns of stars seen in the sky. However, although the stars in any constellation are all in the same general direction in the sky, the different stars in a constellation may be at very different distances from Earth, hence constellations may not be real associations of stars in space, just stars in the same general direction as seen from Earth.

Only the nearest galaxies are visible to the naked eye, as relatively faint smudges of light, although two of the very nearest galaxies, the Magellanic Clouds, are visible are moderately large clouds from the Southern hemisphere.

Answer:

2,500,000W or 2.5MW

Explanation:

The power lost due to resistance is given by I^2R. We must first obtain R as follows;

Resistance per kilometer= 0.050Ω/km

Distance covered= 200km

R = 200km x 0.050Ω/km = 10Ω

The lost power as a 500A current passes through the powerline is:

P = I²R

P= 500² x 10

P= 2,500,000 W or 2.5MW

The resistive power loss in 200 km of the powerline is of 2.5 MW.

Given data:

The root mean square voltage is, V' = 500000 V.

The magnitude of current through the power line is, I =500 A.

The magnitude of resistance of cable is, R = 0.050 Ω/km.

The length of powerline is, L = 200 km.

Whenever there is a flow of current through the wire, then there are various losses out of which the power loss is a major factor. The mathematical expression for the power loss is given as

P = I²R

Solving as,

P= 500² x 10

P= 2,500,000 W or 2.5MW

Thus, we can conclude that the resistive power loss in 200 km of the powerline is of 2.5 MW.

Answer:

λ = 1.8 x 10⁻⁷ m = 180 nm

Explanation:

First we find the work function of tungsten by using the following formula:

∅ = hc/λmax

where,

∅ = work function = ?

h = Plank's Constant = 6.626 x 10⁻³⁴ J.s

c = speed of light = 3 x 10⁸ m/s

λmax = maximum wavelength for photoelectric emission = 230 nm

λmax = 2.3 x 10⁻⁷ m

Therefore,

∅ = (6.626 x 10⁻³⁴ J.s)(3 x 10⁸ m/s)/(2.3 x 10⁻⁷ m)

∅ = 8.64 x 10⁻¹⁹ J

Now we convert Kinetic Energy of electron into Joules:

K.E = (1.5 eV)(1.6 x 10⁻¹⁹ J/1 eV)

K.E = 2.4 x 10⁻¹⁹ J

Now, we use Einstein's Photoelectric Equation:

Energy of Photon = ∅ + K.E

Therefore,

Energy of Photon = 8.64 x 10⁻¹⁹ J + 2.4 x 10⁻¹⁹ J

Energy of Photon = 11.04 x 10⁻¹⁹ J

but,

Energy of Photon = hc/λ

where,

λ = wavelength of light = ?

Therefore,

11.04 x 10⁻¹⁹ J = (6.626 x 10⁻³⁴ J.s)(3 x 10⁸ m/s)/λ

λ = (6.626 x 10⁻³⁴ J.s)(3 x 10⁸ m/s)/(11.04 x 10⁻¹⁹ J)

λ = 1.8 x 10⁻⁷ m = 180 nm

Answer:

As per Heidegger's notion, the relationship between science, technology, and the good life is complex and multifaceted. While these advancements have brought forth many benefits, it is important to consider the potential consequences of our engagement with science and technology and to strive towards a balanced and responsible use of these tools.

Martin Heidegger's notion of "bringing forth" refers to the way in which human beings actively shape the world through their engagement with technology and the natural world. He argues that our relationship with technology and science can both reveal and conceal the nature of the world, and that this relationship can have significant implications for human life and well-being.

In considering the impact of science and technology on the good life, it is important to examine both the benefits and the potential negative consequences of these advancements. On the one hand, science and technology have undoubtedly brought forth many improvements in our standard of living, such as medical advancements, access to information, and increased efficiency and convenience in many aspects of life.

On the other hand, some have argued that our growing reliance on technology can lead to a loss of authenticity and meaningful engagement with the world. Additionally, there are concerns about the environmental impacts of science and technology, as well as the potential for technology to perpetuate inequalities and reinforce oppressive power structures.

The spring with the higher stiffness is Spring 1. To determine this, we can look at the amount of work required to compress each spring by a given amount.

Compressing Spring 1 by 0.20m requires 150J of work, while compressing Spring 2 by 0.30m requires 210J of work. Since more work is required to compress Spring 2 by a smaller amount than it is to compress Spring 1, we can infer that Spring 1 is stiffer than Spring 2.

Stiffness is the amount of force required to move the spring a certain distance. The higher the stiffness, the more force is required to move the spring. Since it takes more force to compress Spring 1 than it does to compress Spring 2, Spring 1 is stiffer.

We can also look at the amount of work required to stretch each spring by a given amount. Stretching Spring 1 by 0.20m requires 150J of work, while stretching Spring 2 by 0.30m requires 210J of work. Again, since more work is required to stretch Spring 2 by a smaller amount than it is to stretch Spring 1, we can infer that Spring 1 is stiffer than Spring 2.

To summarize, Spring 1 is stiffer than Spring 2 since it requires more work to compress and stretch it by a given amount. Compressing Spring 1 by 0.20m requires 150J of work, while compressing Spring 2 by 0.30m requires 210J of work. Stretching Spring 1 by 0.20m requires 150J of work, while stretching Spring 2 by 0.30m requires 210J of work.

Answer:

The coefficient of friction causes the force on the object to be less than its initial reading on the spring scale.

Explanation:

Since the block reads 24.5 N before the block starts to move, this is its weight. Now, when the block starts to move at a constant velocity, it experiences a frictional force which is equal to the force with which the student pulls.

Now, since the velocity is constant so, there is no acceleration and thus, the net force is zero.

Let F = force applied and f = frictional force = μN = μW where μ = coefficient of friction and N = normal force. The normal force also equals the weight of the object W.

Now, since F - f = ma and a = 0 where a = acceleration and m = mass of block,

F - f = m(0) = 0

F - f = 0

F = f

Since the force applied equals the frictional force, we have that

F =  μW and F = 23.7 N and W = 24.5 N

So, 23.7 N = μ(24.5 N)

μ = 23.7 N/24.5 N

μ = 0.97

Since μ = 0.97 < 1, the coefficient of friction causes the force on the object to be less than its initial reading on the spring scale.

If the distance between two point charges is tripled, the mutual force attraction between them will be reduced by a factor of 1 by 9th.

The square of the separation distance is inversely correlated with the electrostatic force which is the mutual force of attraction. F is therefore nine times smaller, or one-ninth the original value if the distance between the charges is made three times larger.

A point charge is defined as a charge which doesn't have any area or volume and hence it appears as a point.

The mutual force of attraction which is also referred to as the electrostatic force of attraction is defined as the force that exists between two charged particles in a 3D space.

Answer:

17.78 m/s

Explanation:

Average speed is found by simply dividing the distance travelled by the time that it took to finish the trip. It's measured in meters per second (m/s), so first convert the quantities.

1 km = 1000 m, so 16 km is 16000 m

0.25 hours is 15 minutes. Since 1 minute is 60 seconds, then 15 minutes must be 900 seconds.

Thus:

average speed = total distance/total time = 16000 m / 900 s = 17.78 m/s

Explanation:

In a tensile force measurement using a strain gauge, the strain gauge is typically attached to the surface of the material experiencing the tensile force. The strain gauge is a resistive sensor that changes its electrical resistance in response to the deformation or strain of the material.

When a tensile force is applied to the material, it causes the material to deform. This deformation results in a change in the length and cross-sectional area of the material. The strain gauge, being bonded to the surface of the material, also experiences this deformation, which causes a change in its resistance.
The relationship between the change in resistance (∆R) and the tensile force (P) can be derived using the concept of strain and the gauge factor (GF) of the strain gauge. The gauge factor is a constant that represents the sensitivity of the strain gauge and is typically provided by the manufacturer.
The relationship is given by the equation:
∆R = GF * R * ε
Where:
∆R is the change in resistance of the strain gauge,
GF is the gauge factor of the strain gauge,
R is the initial resistance of the strain gauge,
ε is the strain experienced by the material.
To determine the change in resistance for a strain gauge installed on a beam being pulled axially by a 50 kN tensile force, additional information is required. Specifically, the length of the beam and the modulus of elasticity (E) of the material. With this information, the strain (ε) can be calculated using the equation
ε = δL / L
Where:
δL is the change in length of the beam,
L is the initial length of the beam.
Once the strain is determined, the change in resistance can be calculated using the derived relationship ∆R = GF * R * ε, where GF and R are given as 2 and 1200, respectively.

Electron microscopes provide much greater resolving power than light microscopes because they use electrons instead of light to form an image.

Resolving power refers to the ability of a microscope to distinguish between two closely spaced objects as separate entities. Electron microscopes utilize a beam of electrons instead of a beam of light, which allows for a much smaller wavelength. The wavelength of electrons is significantly shorter than that of visible light, which results in greater resolving power.

According to the wave nature of light, the resolution of a microscope is determined by the wavelength of the radiation used to form the image. The resolving power is inversely proportional to the wavelength of the radiation. As the wavelength decreases, the resolving power increases.

Electrons have a much shorter wavelength compared to visible light due to their smaller mass and higher energy. This shorter wavelength enables electron microscopes to visualize extremely small details and structures with high resolution. It allows scientists to observe objects on a nanometer scale, providing much finer details than what can be achieved with light microscopes.

The use of electrons instead of light in electron microscopes leads to a significantly shorter wavelength, resulting in much greater resolving power. This enhanced resolving power enables electron microscopes to capture fine details and visualize structures on a much smaller scale, making them indispensable tools in various scientific fields such as nanotechnology, materials science, and biology.
