Asked by Wiki User

An ebony void refers to a profound emptiness or darkness, often used metaphorically to describe feelings of emptiness, nothingness, or despair. It can symbolize a sense of loss, loneliness, or hopelessness.

Have any spacecraft or space probes visited Saturn?

User Avatar

Asked by Wiki User

Yes, several spacecraft and probes have visited Saturn. The most notable mission is the Cassini-Huygens mission, which arrived in Saturn's orbit in 2004. Cassini spent over 13 years studying the planet and its moons before its mission ended in 2017.

When a ball is traveling at a constant velocity of 50 ms and has been traveling for over 2 minutes what is the balls acceleration?

User Avatar

Asked by Wiki User

If the ball is traveling at a constant velocity of 50 m/s, then its acceleration is 0 m/s^2. Acceleration is the rate of change of velocity, so if the velocity is constant, there is no change in velocity, and therefore no acceleration.

What is the rocket fuel called in a ciggarete?

User Avatar

Asked by Wiki User

The rocket fuel in a cigarette is typically referred to as tobacco, which contains nicotine and other chemicals that when burned produce smoke.

How long does it take to get to Saturn from the earth?

User Avatar

Asked by Wiki User

It takes about 6.7 years for a spacecraft to travel from Earth to Saturn, depending on the specific trajectory and speed of the spacecraft. The distance between Earth and Saturn can vary as both planets orbit around the Sun at different speeds.

Have there ever been any space landings on Saturn?

User Avatar

Asked by Wiki User

No, there have been no space landings on Saturn. Saturn is a gas giant and does not have a solid surface for spacecraft to land on. However, the Cassini spacecraft did study Saturn and its moons from orbit before its intentional descent into the planet's atmosphere in 2017.

What is the relative surface gravity of earth?

User Avatar

Asked by Wiki User

The surface gravity of Earth is approximately 9.81 m/s^2, which means that objects on Earth's surface experience a gravitational acceleration of 9.81 meters per second squared. This is what keeps us grounded and determines the weight of objects on the planet.

Does the action force in a rocket engine act on the hot gases or on the rocket?

User Avatar

Asked by Wiki User

The action force in a rocket engine acts on the hot gases expelled from the engine. As the gases are expelled at high speed in one direction, the rocket experiences a reaction force in the opposite direction, propelling it forward. This is described by Newton's third law of motion: for every action, there is an equal and opposite reaction.

How many spacecraft have visited Neptune?

User Avatar

Asked by Wiki User

Only one through 2009. The Voyager 2 probe visited Neptune in 1989, having previously passed Jupiter, Saturn, and Uranus. Voyager 2 took the first close-up photos of the Neptunian moon Triton and discovered 5 new inner moons.

What was the name of the first spaceship to Mars?

User Avatar

Asked by Wiki User

The first spacecraft to successfully land on Mars was the Viking 1, which touched down in 1976.

What does Code 27 mean on 1994 Plymouth Voyager?

User Avatar

Asked by Wiki User

Code 27 on a 1994 Plymouth Voyager typically refers to an issue with the injector control circuit. This could be due to a faulty fuel injector, wiring problem, or engine control module issue. It is recommended to inspect the injector, related wiring, and connections to diagnose and resolve the problem.

How is a rockets fuel made?

User Avatar

Asked by Wiki User

Rocket fuel is typically made by combining liquid oxygen (LOX) with a fuel source such as liquid hydrogen, kerosene, or a combination of various chemicals. These components are mixed in specific ratios to optimize performance and efficiency. The fuel is then stored in tanks on the rocket until it is ignited during the launch process.

What state is the HALE telescope from?

Asked by Wiki User

Mercury is the closest planet to the sun in our solar system. It orbits approximately 36 million miles away from the sun.

Is Time Travel Real?

User Avatar

Asked by Wiki User

As of current scientific understanding, time travel as commonly portrayed in science fiction is not possible. The laws of physics, particularly causality and the second law of thermodynamics, present significant challenges to the concept of time travel. However, some theoretical models such as wormholes and time dilation suggest that time travel to the future might be theoretically possible under certain conditions.

How momentum cause rocket propulsion and how rocket accelerates in space vacuum?

User Avatar

Asked by TariqJamal

Momentum in a rocket is generated by expelling propellant at high speed through a nozzle, creating an equal and opposite reaction force. In the vacuum of space, there is no air resistance to oppose the rocket's thrust, allowing it to accelerate continuously as long as it expels propellant.

When a rocket rises what is the reaction force?

User Avatar

Asked by Wiki User

When a rocket rises, the reaction force is the force pushing downwards on the rocket caused by the expulsion of exhaust gases in the opposite direction. This reaction force propels the rocket upward according to Newton's third law of motion.

How much information does a Hubble Space Telescope hold?

User Avatar

Asked by Wiki User

The Hubble Space Telescope is not designed to store information like a computer or hard drive. It collects astronomical data through its instruments and transmits this data back to Earth for analysis and storage by scientists and researchers.

What do scientists use to study the universe?

User Avatar

Asked by Wiki User

Scientists use a variety of tools to study the universe, including telescopes (both on Earth and in space), satellites, and instruments that detect different forms of radiation such as radio waves, X-rays, and gamma rays. They also use computer simulations and mathematical models to analyze and interpret the vast amount of data collected from these observations.

How long does it take from Jupiter to earth?

User Avatar

Asked by Wiki User

The time it takes for light to travel from Jupiter to Earth varies depending on the relative positions of the two planets in their orbits around the Sun. On average, light takes about 32 minutes to travel one way from Jupiter to Earth.

What happens when you split the atom in space?

User Avatar

Asked by Wiki User

When an atom is split in space, it releases a tremendous amount of energy in the form of radiation and particles. This can result in a nuclear explosion or chain reaction if not controlled. The debris and radiation from the split atom can also pose a hazard to spacecraft and astronauts in the vicinity.

What is the fastest rocket powered aircraft not with a rocket?

User Avatar

Asked by Wiki User

The fastest rocket-powered aircraft is the North American X-15, which achieved a top speed of Mach 6.7 (about 4,520 mph). If you are looking for the fastest aircraft that is not rocket-powered, the X-15 still holds the record as it used rocket engines to reach its high speeds.
