I would recommend watching TV shows like "How the Universe works" or "Space's deepest Secrets".

so, if there were no gravity ?

no bigger bodies or structures would have formed at all. the universe would be one big "sea" of hydrogen atoms (and some helium and very few other atoms, whatever the Big Bang created by itself - depending on what the Big Bang really was, and if there really was such a thing) floating through the ever expanding spacetime.

yes, some tiny structures would have formed via electrostatic forces, and also via chemical reactions forming some larger molecules of atoms driven just by chance and the coincidence that atoms would even get that close to each other. but not many, as the larger atoms (like oxygen) can only be created by fusion of smaller atoms, which can only happen with immense pressure, which can only happen by gravity squeezing atoms together in cores of stars and such.

in other words, no black holes, no Galaxies around them, no stars in them, no planets and moons, no asteroids and comets around them would have formed.

the universe would be dark from the very beginning, just glimmering with the leftover background radiation from the Big Bang (or whatever it was).

there would be actually nothing to observe, literally.

When we see the brightest star in the constellation Orion just rising above your eastern horizon at 10 pm and One week later at 10 PM this same star will be at its highest point in the sky, directly overhead .

The position of Stars in the sky changes as the Earth rotates on its axis.

As the Earth rotates, different stars appear to rise in the east and set in the west.

If we see the brightest star in constellation Orion just rising above our eastern horizon at 10 PM, and 1 week later at 10 PM, this same star will be at its highest point in the sky, directly overhead.

This is because the Earth has rotated 1 full revolution in a week, which causes the star to move from the eastern horizon to the overhead position.

Your legs appear to be unattached at the knees where they meet the water, to refract when light waves go from the pool into the air.

Electromagnetic waves come in many varieties. The microwaves in your oven, radio waves, and X-rays are examples of additional electromagnetic waves.

A fluctuating electric field (E) and a varying magnetic field (B) that are perpendicular to each other and the direction of travel are thought to make up light waves.

Sound goes from the air to the water at a different speed. When sound travels through different media, some of it is reflected and only some of it is transferred.

As the acceleration of charged particles (photons) results in light, according to the electromagnetism law, light is an electromagnetic wave. Light may spread without a medium, much like an electromagnetic wave.

The slope of the plot of T vs. m is, m = (k/4π²).

The period of one oscillation of a spring-mass system is denoted by the letter T, and it is the time required for one complete cycle of motion, starting at any point in the cycle and returning to that same point.

The equation for the period T of a spring-mass system is, T = 2π √(m/k),

where k is spring constant and m is the mass of load hanging from the spring.

To find the slope of the plot of T vs. m, we can rewrite this equation in the form, T² = (4π²/k) m.

The magnitude of the torque on a molecule depends on various factors such as the orientation and magnitude of the electric dipole moment of the molecule, the electric field strength, and the angle between the electric field and the dipole moment.

The general formula for the magnitude of the torque, τ, on a molecule in an electric field is given by:

τ = p * E * sinθ

where p is the electric dipole moment of the molecule, E is the electric field strength, and θ is the angle between the electric field and the dipole moment.

The speed of the stream when the distance and time taken to travel are given is calculated to be 1.41 km/h.

A boat takes 3.4 hrs to travel 30 km.

It takes 5 hrs to return through same distance.

The speed of the boat during the downstream is, v + u = D/t

where,

v is the speed of the boat

The most important difference in development between Isaac Newton's theory of planetary motion and that of Johannes Kepler was the explanation of why planets move in the way that they do.

Kepler's laws of planetary motion were based on extensive observations of the positions of the planets in the sky, and he discovered that planets move in elliptical orbits around the sun, with the sun located at one of the foci of the ellipse.

Isaac Newton, on the other hand, was able to provide a physical explanation for why planets move in elliptical orbits around the sun. Newton's law of universal gravitation stated that all objects in the universe are attracted to each other with a force that is proportional to the product of their masses and inversely proportional to the square of the distance between them.

Using this law, Newton was able to demonstrate that the gravitational attraction between a planet and the sun causes the planet to move in an elliptical orbit.

The current across a drain resistor is the same as the current across the drain to source in a MOSFET because the MOSFET behaves as a voltage-controlled resistor.

A resistor is an electrical component that is used to reduce the flow of current in an electrical circuit. It works by creating electrical resistance, which is measured in ohms. This resistance opposes the flow of current, allowing engineers to control the voltage and current levels in a circuit. Resistors are used in many different types of applications, from controlling the speed of motors to regulating the flow of current in digital circuits.

The resistance of the MOSFET channel is controlled by the voltage applied to the gate. If the gate voltage is increased, the resistance of the channel decreases, allowing more current to flow from the drain to the source. Since the drain resistor is in series with the MOSFET channel, the same current must also flow through the resistor.

The bathtub on the bottom floor will fill faster assuming frictionless pipes and isothermal flow.

In an isothermal flow, the temperature remains constant and the pressure decreases as the height increases. This means that the pressure at the bottom floor is higher than the pressure at the top floor. As a result, the water will flow more quickly through the pipes to the bottom floor, filling the bathtub there faster.

This can be understood by considering the relationship between pressure and flow rate in a pipe: flow rate is proportional to the pressure difference. In this case, the pressure difference between the top and bottom floors is driving the flow of water, so the bathtub on the bottom floor will fill faster.

It was determined that extraordinary atoms and exceptional basic particles, theoretically with the same amount of count, have thought distinct masses. Mass in current physics has a couple of definitions that might be conceptually distinct, but bodily equivalent. The mass may be experimentally defined as a degree of the frame's inertia, which means the resistance to acceleration (alternate of velocity) whilst a net force is implemented. The object's mass also determines the strength of its gravitational enchantment to different bodies.

The SI base unit of mass is the kilogram (kg). In physics, mass isn't the same as weight, even though mass is regularly determined by means of measuring the object's weight with the use of a spring scale, in place of a stability scale comparing it without delay with known hundreds.

Telescopes come in a variety of sizes and configurations, and are used by astronomers and other scientists to observe the properties of distant stars, galaxies, and other celestial objects. Telescopes are also used by hobbyists and amateur astronomers to observe the night sky. While there are many types of telescopes, the most common are refracting and reflecting telescopes. Refracting telescopes use a combination of lenses to collect and focus light, while reflecting telescopes use mirrors to do the same.
