### How many degrees of freedom does a concentric mate have?

Space and AstronomyFor example, a concentric mate removes two translational degrees of freedom and two rotational degrees of freedom between two rigid bodies. Adding a distance or coincident mate to the faces removes the final translational degree of freedom. How many degrees of freedom does a fixed component have? Each component in an assembly initially has six

### What is the difference between astronomy and planetary science?

Space and Astronomy“Planetary Science is the study of the Earth, the Solar System and the bodies within the Solar System (more or less exclusive of the Sun), the space environment within which the planets were formed and evolved and interacted, and planetary systems around other stars.” It is considered a branch of Astronomy, the … Is planetary

### Do the stars change position?

Space and AstronomyThe monthly positions of the stars change because of the interaction between the rotation of the earth around its axis and the orbit of the earth around the sun. The stars rotate around the north and south celestial poles; hence the stars are always moving relative to a point on the earth’s surface. Do stars

### How many Super Earths have been found?

Space and Astronomy30 super-Earths30 super-Earths had been discovered, 24 of which were first observed by HARPS. What is a super-Earth and how many have been discovered? Astronomers have found three planets—TOI-561b, TOI-561c and TOI-561d—using NASA’s planet-hunting Transiting Exoplanet Survey Satellite (TESS ) space telescope and Keck Observatory in Hawaiʻi. How many habitable Earths are there? Based on

### Can solar flares destroy electronics?

Space and AstronomySolar flares are particularly damaging to objects in space and can destroy electronics in satellites and even cause them to fall out of orbit. The earth has been hit with big solar flares in the past. The biggest flare that we know about happened in 1859 and blew up telegraph equipment around the world. Can

### How do you find the sine ratio?

Space and AstronomyThe definition of the sine ratio is the ratio of the length of the opposite side divided by the length of the hypotenuse. Well, the length of the side opposite ? C is the length of the hypotenuse, so sin ? C = c/c = 1 Because ? How do you find the sine and

### How do you code a distance in Java?
