Calculate the gradient nabla f of the function f (x, y, z) = r = square root {x^2 + y^2 + z^2}. How do you calculate a parsec? Calculate the gradient nabla f of the function f (x, z) = x^2 + z^2. Given the quantities a = 3.2 m, b = 8.8 s, c =...
How do you calculate a parsec? Why is the parallax method not useful for measuring the distances of stars more than 100 light-years away?. Within the visible Universe, is the sum of all gravity constant? If not, then why not? How do we measure Dark Matter?
Once they had the distance to Mars, they could also calculate the distance from Earth to the sun. Because his methods were more scientific, Cassini usually gets the credit. These techniques are also why astronomers continue to use the distance from Earth to the sun as a scale for ...
As a general rule, the tax rate only applies to the portion of income which falls into each range. And in some places, you may need to consider local income taxes, too. Here's a breakdown for each state. Arkansas With graduated income tax rates from 2% to 4.9% for 2022, state taxes...
Astronomers observe a similar effect with stars due to Earth's orbit. By comparing star positions six months apart, they measure this parallax angle (Θ). Using Θ and Earth's orbit radius (R), they calculate a star's distance (D) as: D = RCotΘ. This is effective for stars within ...
Astronomers (professional or amateur) can measure a star's brightness (the amount of light it puts out) by using a photometer or charge-coupled device on the end of a telescope. If they know the star's brightness and the distance to the star, they can calculate its luminosity — the am...
How many minutes are in a century? A jogger runs 6.0 km E, then 4.0 km N, and finally 2.0 km W. The entire trip takes 2.0 h to complete. Calculate the jogger's (a) average speed (b) average velocity? A man walks 3 km in 1 hour. What ...
Then calculate your answer using the fact that 1 in. = 2.54 cm. Round answer appropriately. The answer shoul 168 kilometers in 3.25 hours. How long to go 240 km? Solve for m in km + 5x = 6y? Carl needs to find the number of centimeters in 0.4 kilometers. Write a propo...
Now, to calculate the gravitational force between the Earth and the Sun at the Earth's average orbital radius from the Sun, here is the basic data: Sun: mass 1.989 X 1032 gr Earth: mass 5.976 X 1027 gr; average orbital radius from Sun 1.49596 X 1013 cm So that… F = 1.989 X 1032...
What do you understand by the radius of curvature of a spherical mirror? How do you calculate a parsec? How does the light-collecting area of an 8-meter telescope compare to that of a 2-meter telescope? What is the full form of laser?
