Explanation:

i just took the assignment

Glass, paper, and plastic are good insulators. The material that does not allow the flow of current through them is known as the insulators.

An electrical insulator is a substance that prevents electric current from flowing freely. The electrons in the insulator's atoms are closely bonded and cannot travel easily.

Other materials, such as semiconductors and conductors, carry electricity more easily. The characteristic that characterizes an insulator.

Gold and silver are good conductors of electricity. While glass, paper, and plastic are good insulators.

Explanation:

The spectrum observed from the Sun (or any star) would exhibit an absorption spectrum. This is because the outer gaseous atmosphere of the star absorbs specific wavelengths of light, resulting in dark absorption lines in the spectrum.

In the cooler, lower-density outer atmosphere, where white light from the star travels, some atoms or molecules in the atmosphere absorb photons with particular energy. In the spectrum, these absorptions show up as black lines at specific wavelengths. The specific set of absorption lines that each element or molecule generates results in a distinctive pattern that can be used to identify the elements that are present in the star's atmosphere.

The absorption spectrum offers insightful data on the chemical make-up and physical characteristics of the star. Astronomers can ascertain the elements present, their abundances, and other characteristics like the temperature, pressure, and velocity of the star's atmosphere by examining the absorption lines.

The lux level at the brightest point on the poster is 18.3 lx.

This is a very low value and is not a suitable level. The lighting level of the classroom should be at least 300 lx. Using spot lighting in a classroom to provide lighting to desks has several issues such as: Since spotlights have a narrow beam angle, they only provide light to a small area.

This is not ideal for classrooms since all the desks need to be adequately lit. Students may experience glare from the light source if they are looking directly at it. This can cause discomfort and lead to eye strain and headaches. Spot lighting can create shadows, making it difficult for students to see what they are working on.

Shadows can also create a sense of insecurity for some students and may impact their learning.The uniformity of the lighting may be affected since the lighting is only focused on certain areas. As a result, some parts of the classroom may be too dark, while others may be too bright.

This can cause distractions and make it difficult for students to concentrate.

The types of electromagnetic radiation in order of decreasing frequency will be D. ultraviolet > infrared > microwave > radio.

This is the radiation that travels in waves and possesses both an electric and magnetic field. Both natural and artificial sources contribute to it. The energy levels of electromagnetic radiation can range from low to high. It consists of x-rays, gamma rays, infrared light, visible light, ultraviolet light, radio waves, and microwaves.

When a charged particle, like an electron, changes its velocity—that is, when it is accelerated or decelerated—electromagnetic radiation is created. As a result, the charged particle loses the energy of the electromagnetic radiation that is thus created.

It should be noted that radio has highest wavelength and ultraviolet has lowest wavelength.

(i) For position coordinates p(x, y),  the path of horizontal projectile is parabolic.

(ii)  The time to reach the ground is 0.96 s.

(iii) The distance from the cliff of the ball on hitting the ground is 9.6 m.

(iv) The velocity with which the ball hits the ground is 9.4 m/s.

(v) The direction of the ball to the horizontal just before it hits the

ground is 90 degrees.

When an object is thrown at an angle from the horizontal direction, the object is said to be in projectile motion. The object which follows the projectile motion.

Given is a ball is thrown forward horizontally from the top of a cliff

with a velocity of 10m/s.  The height of the cliff above the ground is 4.5m.

(i) The equation formed by the ball is at point (x,y) given by

y =yo + Voy x t - 1/2gx²

The equation is in the form of parabola.

Thus, the ball follows parabolic path.

(ii) The time to reach the ground is

t = √2h/g

t =  √(2x 4.5)/9.81

t= 0.96 s

iii) Horizontal distance traveled

R = u x t

R = 10 x 0.96

R = 9.6 m

Thus, the distance from the cliff of the ball on hitting the ground is 9.6 m.

(iv) The velocity with which the ball hits the ground.

v = √2gh

Plug the values, we get

v = √(2 x 9.81 x 4.5)

v = 9.4 m/s

(v) The direction of the ball to the horizontal will be 90 degrees just before it hits the ground.

This question involves the concepts of the speed of sound, frequency, and temperature.

The temperature of the air is "14.24 °C".

First, we find the speed of sound at the given temperature:

v = fλ

where,

Therefore,

v = (695 Hz)(0.49 m)

v = 340.55 m/s

Now, the relationship between the speed of sound and temperature can be given by the following formula:

\(\frac{v}{v_o} = \sqrt{\frac{T}{273\ k}}\\\\T = (273\ k)(\frac{v}{v_o})^2\\\\\)

where,

Therefore,

\(T = (273\ k)(\frac{340.55\ m/s}{332\ m/s})^2\)

T = 287.24 k = (278.24 k -273) °C

T = 14.24 °C

Phytophotodermatitis happens when certain plant chemicals cause the skin to become inflamed following exposure to sunlight.

Phytophotodermatitis is induced by the action of long wavelength ultraviolet radiation (UVA) on a plant chemical called furocoumarins (psoralens) on the skin surface. Contact with the plant, fruit or vegetable may have been brief and unnoticed.

Explanation:

The water mixture's ultimate temperature is around 27.5°C or 300.5 K.

The conservation principle of energy, which stipulates that the energy obtained by the cold water must equal the power lost by the hot water, may be used to determine the final water's temperature in this combination.

This idea may be expressed numerically as follows:

Where: m1c1(T1 - T) = m2c2(T- Look . top)

m1 = the hot water's mass (0.4 kg)

(4200 J/kg-K) is the particular boiling point of water.

T1 is the hot water's starting temperature (80 °C is 353 K).

T = the water mixture's ultimate temperature

m2 = the cold water's mass (1 kg)

Water has a particular heat capacity of 4200 J/kg-K, or c2.

T2 is the cold water's starting temperature (20 °C, or 293 K).

Streamlining and addressing

T = (m1c1T1 + m2c2T2) / (m1c1 + m2c2)

T = (0.4 kg x 4200 J/kg-K x 353 K + 1 kg x 4200 J/kg-K x 293 K) / (0.4 kg x 4200 J/kg-K + 1 kg x 4200 J/kg-K)

T = 300.5 K

The total side to side distance at the top of the building, covered during such an oscillation is 8.4 cm.

Solution:

The height of building is, h = 152 m.

The frequency on windy days is, f = 0.17 Hz.

The acceleration on the top of building is, a = 2/100g (Here g is gravitational acceleration).

\(a = A \times \omega ^{2}\)

\(a = A \times (2\pi f) ^{2}\)

\(\frac{2}{100} \times g = A \times (2\pi \times 0.17) ^ 2\)
