1. IN YOUR OWN WORDS, what do you think is the biggest role of telescopes in Modern Astronomy?
The orbital period of Planet A is 16 years and its average distance to Star B is 5.25 a.u. Another planet called Planet C has an average distance of 10.3 a.u. from Star B, using Kepler’s Third Law of Planetary Motion, compute the orbital period of Planet C to Star B in days.
(b) Determine the angular velocity ω of the telescope as it orbits around the Sun.
1.The period of Planet X to orbit on a certain star is 15.382 years. Given this data, compute the distance from Planet X to the star in miles. (NOTE: 1 km = 0.621 mile).
What would be the diameter of the erth if it had the density of a neutron star?
What would be the diameter of the earth if it had the density of neutron star ?
object traveling at 90% speed of light what would it appear as to observer from sending point ,the object ,and destination point, and from a 4th observation from 90% angle, 4th point is most important and observed effects of movement on spacetime from 4th point...
A principle section of calcite crystal cut always in parallelograms with angles ______.
Assume that a gravitational anomaly in the solar system has shifted afield of asteroids into Earth’s orbit, and the field is now moving directly towards Earth. The asteroid field has a density of ρ (asteroids/volume), and each asteroid has an average mass of m. The asteroid field stretches over a distance d in Earth’s path. Assume that the Earth moves with a velocity of v, the asteroids with u, and that v u. Let R be the radius and M the mass of the Earth. The Earth collides with the asteroid field: v u Show that the slow-down ∆v of the Earth due to the asteroid collisions is given by: ∆v = v 1 − 1 1 + πR2dρ m M
1. A certain type of elementary particle travels at a speed of 2.70 𝑥 108 𝑚/𝑠. At this speed, the average lifetime is measured to be 4.76 𝑥 10−6 𝑠. What is the particle’s lifetime at rest?
