Archimedes, on the other hand, states that the amount of water (equal to 16000N) will be reduced by 3% since seawater has a specific gravity that is roughly 3% higher than freshwater.

900 000 metric tonnes of water are removed by it. 300,000 elephants would be the equal. The air inside a ship is significantly less dense than water. It floats because of that. The key concept is that the body "floats," which is the underlying presumption in this situation.

The magnitude of the radial acceleration of the car 10m/sec²

Given Velocity v = 50m/sec

Diameter D = 500m

Radius r = 250m

Acceleration a = [tex]v^{2}[/tex]/r = 2500/250 = 10m/sec²

The rate of change in an object's velocity with respect to time is known as acceleration in mechanics. In vector quantities, accelerations exist (in that they have magnitude and direction). [1] [2] The direction of the net force that is acting on an object determines its acceleration. Newton's Second Law[3] states that the sum of the effects of two causes determines the size of an object's acceleration:

The net balance of all external forces acting on that thing — magnitude is directly proportional to this net resulting force; that object's mass, depending on the materials out of which it is built — magnitude is inversely proportional to the object's mass.

Based on the provided information, it can be predicted that the circadian rhythms for the astronauts would be drift toward a slightly longer cycle. (Option A)

A circadian rhythm, also known as circadian cycle, refers to a natural, internal process that regulates the sleep–wake cycle and is repeated roughly every 24 hours. It can refer to any process that originates within an organism and responds to the environment. These natural processes respond primarily to light and dark and affect most living things. A zeitgeber refers to any external cue or environmental cue that synchronizes an organism's biological rhythms such as circadian rhythm, usually naturally occurring and serving to entrain to the Earth's 24-hour light/dark and 12-month cycles. Circadian rhythms that are expressed in the absence of any 24-hour signals from the external environment are called free running, which are slightly longer cycle than usual. Hence, in the absence of external cue, the circadian rhythms for the astronauts would drift toward a slightly longer cycle.

If an object doubles its luminosity in 10 hours, emitting source of light can be about 10 light hours across.

Luminosity, L, is a measure of the total amount of energy radiated by a star or other celestial object per second. This is therefore the power output of a star. A star's power output across all wavelengths is called its bolometric luminosity. A star's luminosity can be determined from two stellar characteristics: size and effective temperature. The difference between luminosity and apparent brightness depends on distance.

Since, the luminosity of the object doubles in 10 hours, emitting source of light can be about 10 light hours across.

In a photoelectric effect experiment at a frequency above the cut off frequency the number of electrons ejected is proportional to the number of photons that hit the sample per second.

The photoelectric current is measured in relation to the intensity of the incident radiation at a specific frequency and potential between the metal plate and collector. It demonstrates that incident radiation intensity and photoelectric current are inversely correlated. The photoelectric current shows how many photoelectrons are released each second.

The work that has been done by air resistance during this time is 55800 k m²/s².

To determine the work done by air resistance during the skydiver's fall, we can use the equation:

W = F × d

where W is the work, F is the force of air resistance, and d is the distance traveled.

The force of air resistance on the skydiver is given by the equation:

F = k × v²

where k is the drag coefficient, which is a measure of the resistance of the air to the movement of the object, and v is the velocity of the skydiver.

To determine the work done by air resistance, we need to determine the distance traveled by the skydiver and the force of air resistance at each point in her fall. The skydiver falls from an altitude of 1500 m to an altitude of 425 m, a distance of 1075 m.

At an altitude of 1500 m, the skydiver is falling at a terminal velocity of 52 m/s. Plugging these values into the equation for the force of air resistance gives us:

F = k × v² = k × (52 m/s)²

To determine the work done by air resistance at this point in the skydiver's fall, we can plug the value of F and the distance traveled into the equation for work:

W = F × d = (k × (52 m/s)²) × 1075 m = 55800 k m²/s²

The work done by air resistance at this point in the skydiver's fall is 55800 k m²/s².

At an altitude of 425 m, the skydiver is falling at a terminal velocity of 52 m/s. Plugging these values into the equation for the force of air resistance gives us:

F = k × v² = k × (52 m/s)²

To determine the work done by air resistance at this point in the skydiver's fall, we can plug the value of F and the distance traveled into the equation for work:

W = F × d = (k × (52 m/s)²) × 1075 m = 55800 k m²/s²

The work done by air resistance at this point in the skydiver's fall is 55800 k m²/s².

To determine the total work done by air resistance during the skydiver's fall, we can add the work done at each point in the fall:

W_total = W_1500m + W_425m = 55800 k m²/s² + 55800 k m²/s² = 111600 k m²/s²

The total work done by air resistance during the skydiver's fall is 111600 k m²/s².

Note that this calculation assumes that the drag coefficient k is constant throughout the skydiver's fall. If the drag coefficient changes during the fall (for example, if the skydiver deploys a parachute), additional calculations will be needed to determine the total work done by air resistance.

The inductance that must be connected to a capacitor is 5* 10⁻²¹ H.

If f is the frequency and λ is the wavelength of an electromagnetic wave, we know the relation between them as v = f * λ

The frequency is same as the frequency of oscillation of the current in the LC circuit of the generator.

f = 1/(2π* √LC)

where, C is the capacitance

L is the inductance

So, λ/(2π* √LC) = c

Given that, λ = 550* 10⁻⁹ m

C = 17 * 10⁻² F

c is the speed of light

Making L as subject, we have

L = λ²/(4π² C* c²) = (550* 10⁻⁹)² / [4π²(17 * 10⁻²) (3* 10⁸)²] = 5* 10⁻²¹ H

Krypton was soon revealed to have formerly been a planet like Earth, only older by eons and possessing. All the advantageous advancement that entailed, starting in the Superman comic strip (though the downside was the hint that Krypton exploded due mainly to old age).

Superman's ability to defy gravity is also explained by another school of thinking, although with a slight variation. Krypton was a gigantic planet with a gravity so strong that typical humans would be crushed beneath its gravitational pull because it was about 1000 times bigger than Earth.

Therefore, Krypton, which was about 1.5 times the size of Earth and was located 50 light-years from the Sun, orbited the red star Rao.

A ray diagram is a tool used by physicists to explain or predict the behavior of beams of light as they pass through objects such as glass blocks or lenses.

A ray diagram is a diagram that strains the route that light takes so as for a person to view a factor in the photograph of an object. In the diagram, rays are drawn for the incident ray and the meditated ray.

Ray diagrams help us hint at the course of the light for the man or woman to view a point on the photograph of an object. The Ray diagram makes use of lines with arrows to symbolize the incident and reflected ray. It also helps us trace the direction in which the mild travels.

A mild ray is a line that is perpendicular to the mild's wavefronts; its tangent is collinear with the wave vector. light rays in homogeneous media are instant. They bend at the interface between two distinctive media and may be curved in a medium wherein the refractive index modifications.
