In order for the units to be correct, the semi-major axis should be in astronomical units, and the period should be in years. Convert the period into the most appropriate units. For fast-moving bodies with small orbits (like the planet Mercury or the Moon), the most appropriate unit is ...
The mathematical formulation of Kepler's third law gives you a way to calculate planetary periods in terms of that of the Earth or, alternatively, the lengths of their years in terms of an Earth year. To do this, it's helpful to express distance (d) in astronomical units (AU)....
You measure the orbit of S2 around the supermassive black hole at the center of our Galaxy to have a period of 15.56 years and a semi-major axis of 0.1203 arcseconds. You are given that the distance to the Galactic Center is 7940 parsecs. a. Calculate the ...
In addition to the pericentre ω, the mean anomaly Mand, thus, the mean longitude λ, also the orbital period P b and the mean motion n of a test particle are modified by the Dvali-Gabadadze- Porrati gravity. While the correction to P b depends on the mass of the central body ...
Many other radium girls died over the years, but a link was never proven and the company never took responsibility [source: Irvine]. Ionizing Radiation X-ray of a young boy's torso. Sami Sarkis/Getty Images Similar to non-ionizing radiation, ionizing radiation is energy in the form of...
is a small comet with a nucleus measuring just 2.24 miles (3.6 km) across. It was discovered independently by both Ernst Tempel and Horace Tuttle in 1865 and 1866, respectively. The letter "P" indicates it is a periodic comet — a comet with an orbital period ofless than 200 years. ...
The periodic table's organization provides important information about an element's structure and properties. Read on to learn more about how the periodic table was made over 150 years ago and why it's used today. Related:Periodic table of elements quiz: How many elements can you name in 10...
Cultivation was conducted in bottles on an orbital shaker (85 rpm) in a greenhouse for two weeks at 26 °C and a light:dark cycle = 16 h:8 h at an intensity of 50 µmol × m−2× s−1. Triplicates from the preculture were transferred without any further treatment to serve ...
In silico structural models are used to simulate molecular interactions, especially with potential aggregation inhibitors. In a recent study, molecular simulations, molecular docking, and fragment molecular orbital calculations were performed to observe the interaction of tau with curcumin derivatives [89]....
In reality, however, the planets are moving at different rates during their orbits around the sun. Engineers must calculate the ideal orbits for sending a spacecraft from Earth to Mars. Like throwing a dart at a moving target from a moving vehicle, they must calculate where the planet will ...
