No, the sun cannot explain global warming. Global warming is a phenomenon in which the temperature of the Earth's surface and atmosphere is rising continuously due to human activities such as deforestation, burning of fossil fuels, and industrialization.

This increase in temperature cannot be explained only by an increase in solar radiation.There are several factors which contribute to global warming, including greenhouse gases such as carbon dioxide, methane, and water vapor. These gases trap heat in the Earth's atmosphere, which causes the planet's temperature to rise. The sun's radiation does contribute to global warming, but it is not the main cause.

i) To calculate the increase in solar radiation that would cause the Earth to warm up by 1 K, we can use the following formula:ΔS = ΔT / αWhere ΔS is the increase in solar constant, ΔT is the increase in temperature, and α is the Earth's albedo (reflectivity).α = 0.30 is the standard value used for the Earth's albedo.ΔS = ΔT / αΔS = 1 K / 0.30ΔS = 3.33 W/m2So, to explain the increase in temperature of 1 K over the last hundred years, the solar constant would need to increase by 3.33 W/m2.

ii) The observed fluctuation of the solar constant over the past 400 years has been around 0.1% to 0.2%. This is much smaller than the 3.33 W/m2 required to explain the increase in temperature of 1 K over the last hundred years. Therefore, it is unlikely that the sun is the main cause of global warming.

The sun cannot explain global warming. While the sun's radiation does contribute to global warming, it is not the main cause. The main cause of global warming is human activities, particularly the burning of fossil fuels, which release large amounts of greenhouse gases into the atmosphere.

Now,buyantant force

\(difference \: in \: weight \: = volume(body) \times density \: of \: water \: \times g\)

so;

\(50 = {v}^{b} \times 1 \times {10}^{3} \times 9.8m {s}^{2}\)

\( {v}^{b} = \frac{50}{1000 } \times 9.8\)

\( = \frac{50}{9800} \)

\( = 0.0051\)

Now,

\(mass \: in \: air \: = 150n = \frac{150}{9.8kg} \)

\(density = \frac{weght}{volume} \)

\( = \frac{150}{0.0051} \times 9.8 \\ x = 3000\)

The magnitude of the linear impulse experienced by the passenger during this time is 421.2 kg·m/s and the average force experienced by the passenger is approximately 5.44 × 10^2 N.

(a) To calculate the magnitude of the linear impulse experienced by the passenger, we can use the equation:

Impulse = mass × change in velocity

Given:
Mass of the passenger (m) = 70.2 kg
Change in velocity (Δv) = 6.00 m/s - 0 m/s = 6.00 m/s

Substituting the values into the equation, we get:

Impulse = 70.2 kg × 6.00 m/s = 421.2 kg·m/s

Therefore, the magnitude of the linear impulse experienced by the passenger during this time is 421.2 kg·m/s.

(b) To find the average force experienced by the passenger, we can use the equation:

Average force = Impulse ÷ time

Given:
Impulse (I) = 421.2 kg·m/s
Time (t) = 0.774 s

Substituting the values into the equation, we get:

Average force = 421.2 kg·m/s ÷ 0.774 s = 544.0 N (rounded to three significant figures)

Therefore, the average force experienced by the passenger is approximately 5.44 × 10^2 N.

Assuming no air resistance, the acceleration due to gravity is approximately 9.81 m/s^2.

After two seconds, the object will have fallen a distance of:

d = 1/2 * g * t^2

d = 1/2 * 9.81 m/s^2 * (2 s)^2

d = 19.62 meters

During this time, the object's velocity will increase due to gravity by:

v = g * t

v = 9.81 m/s^2 * 2 s

v = 19.62 m/s

Therefore, the object's speed after two seconds will be the vector sum of its initial velocity and the velocity it gained due to gravity:

v_final = sqrt((18 m/s)^2 + (19.62 m/s)^2)

v_final = 25.14 m/s

So the object would be moving with a speed of approximately 25.14 m/s after two seconds of free fall.

Users of the Orbital Motion Interactive can view and investigate how a planet or satellite moves in an elliptical orbit around a central object, such as the Sun.

The route an object takes through space as it revolves around a main body, like a planet or star, is known as an elliptical orbit. The item has an elliptical shape rather than a circular one because the gravitational force acting on it is variable. The semi-major axis, which measures the average separation between the object and the central body, and eccentricity, which determines how the elliptical orbit looks, are the two characteristics that define an elliptical orbit. When an object is nearer to the central body, it moves more quickly, and when it is farther away, it moves more slowly. The periapsis is the location where the object is closest to the central body, and the apoapsis is the location where it is farthest.

There is a disk rotating around an axis, and on this disk, there are two points labeled as "a" and "b." Point "a" is located three times farther from the axis compared to point "b."

Let's assume that the distance of point b from the axis is "r" units. Since point a is three times as far from the axis as point b, the distance of point a from the axis is 3r units.

The speed of a point on a rotating disk is determined by its distance from the axis and the angular velocity of the disk. In this case, the angular velocity is the same for both points a and b, as they are on the same rotating disk.

The formula that relates the speed (v) of a point on a rotating disk to its distance from the axis (r) and the angular velocity (ω) is:

v = ω * r

For point b:

\(v_b = \omega \cdot r\)

For point a:

\(v_a = \omega \cdot (3r)\)

Since the angular velocity (ω) is the same for both points, we can express it as a common factor:

\(v_a = 3 * v_b\)

Therefore, the speed of point a is three times the speed of point b.

Explanation:

The work done by the two forces in moving the chandelier to the given distance is 5,091.2 J.

The work done by a single force on the chandelier is determined by taking the net horizontal force applied on the chandelier over the given distance.

\(W = (F - F_f) d\\\\W = (F sin\theta \ - \ F_f)d\)

where;

\(F_f\) is frictional force = 0 (smooth surface).

\(W = Fsin(\theta) d\\\\W = 1200 \times sin(45) \times 12\\\\W = 10,182.34 \ J\)

When the two forces combine to pull the chandelier, the total work done will be shared by the two forces.

\(W_1 = W_2 = \frac{10,182.34}{2} = 5,091.2 \ J\)

The heat change associated with 37.19 g of liquid water at 5.00 °C changing to solid water at -5.00 °C is approximately 12.4007 kJ.

The heat change associated with a phase change can be calculated using the heat of fusion, which is the amount of heat required to change a given mass of a substance from a solid to a liquid, or vice versa. The heat of fusion for water is approximately 333 J/g.

The heat change associated with 37.19 g of liquid water at 5.00 °C changing to solid water at -5.00 °C can be calculated as:

q = m * ΔHfusion

where m is the mass of the water and ΔHfusion is the heat of fusion. In this case, m = 37.19 g and ΔHfusion = 333 J/g, so:

q = 37.19 g * 333 J/g = 12400.07 J

To convert the heat change from joules to kilojoules, divide by 1000:

q = 12400.07 J / 1000 = 12.4007 kJ

So the heat change associated with 37.19 g of liquid water at 5.00 °C changing to solid water at -5.00 °C is approximately 12.4007 kJ.

 The charge Q is uniformly distributed throughout the sphere. The correct answer is (B)

When a solid conducting sphere is given a positive charge Q, the charge will distribute itself evenly throughout the surface of the sphere due to the repulsion of like charges. This is known as the "Faraday's ice pail experiment".

According to the principle of electrostatics, the charge on a conductor always resides on its surface and distributes itself in a way that the electric field inside the conductor is zero. Since the charge on a conductor always resides on its surface, it follows that the charge Q in this case must be uniformly distributed throughout the surface of the sphere.

Option (A) is not true because the charge is not concentrated at the center of the sphere. If the charge was concentrated at the center of the sphere, the electric field would not be zero inside the conductor, which contradicts the principle of electrostatics.

Option (C) and (D) are not true because the density of the charge does not change radially outward from the center. If the density decreased or increased radially outward, the electric field inside the conductor would not be zero, which again contradicts the principle of electrostatics.

Option (E) is not true because the charge is distributed throughout the entire volume of the sphere, not just on its surface. A solid conductor has free charges that can move throughout its entire volume, so the charge will distribute itself throughout the entire volume of the sphere until the electric field inside the conductor is zero.

Therefore, the correct answer is (B) it is uniformly distributed throughout the sphere.
