The nearest neutron star (a collapsed star made primarily of neutrons) is about 3.00 × 1018 m away from Earth. Given that the Milky Way galaxy (Fig. P1.63) is roughly a disk of diameter ~ 1021 m and thickness ~ 1019 m, estimate the number of neutron stars in the Milky Way to the nearest order of magnitude.

The nearest neutron star (a collapsed star made primarily of neutrons) is about 3.00 × 1018 m away from Earth. Given that the Milky Way galaxy (Fig. P1.81) is roughly a disk of diameter ~ 10²' m and thickness ~ 1019 m, estimate the number of neu- tron stars in the Milky Way to the nearest order of magnitude.

We are going to make a simple approximation of the number of atoms in the universe. Assume all the atoms in the universe are hydrogen. (In actual practice, over 75% of the atoms in the universe are hydrogen.) Assume the sun is a typical star (made of pure hydrogen) has a density of 1.4 g/cm3 and is a sphere with a radius of 7.0*108m Assume that there are 100 billion stars in our Milky Way galaxy that are identical to our sun. Assume that there are 10 billion galaxies in the universe identical to our Milky Way galaxy. How many atoms are there in the universe?
A light-year (ly) is the distance light travels in one year (at speed of 2.998 ×× 108 m/sm/s ). An astronomical unit (AU) is the average distance from the Sun to Earth, 1.50 ×× 108 km. 1 year = 3.156 ×× 107 s. How many meters are there in 1.70 ly? Express your answer using three significant figures. Express in scientific notation! 1.70 ly = _________________m How many AU are there in 1.70 ly light-year? Express your answer using three significant figures. Express in scientific notation! 1.70 ly = _________________AU

Using a single dimensional equation, estimate the number of steps it would take you, walking at your normal stride, to walk from the Earth to Alpha Centauri, a distance of 4.3 light-years. The speed of light is 1:86 x 105A miles/s.

Estimates and orders of magnitude: Four astronauts are in a spherical space station. (a) If, as is typical, cach of them breathes about 700 cm of air with each breath, approximately what volume of air (in cubic meters) do these astronauts breathe in a year? (b) What would the diameter (in meters) of the space station have to be to contain all this air? (c) With the diameter of the space station obtain from part (b), how long the air would last? (d) Suppose the space station can support 4 astronauts within the time interval obtain at part (c), how many astronauts will be required to stay in the space station for them to supply a decade worth of air to breathe?
A student measured the side length of a cube and found it to be 1 = (3.3 + 0.1) cm. The volume (V = 1³) of the cube with its error is (V + U(V)) (Please show me the calculations in details) a) 35.9 ± 0.3 cm³ b) 35.9 +3.3 cm³ c) 35.9 +0.3 m³ d) 35.9 +3.3 m³
I don't understand this. why365.0g is significant figures? I think its effective number is 3, and why 362mL has 3 effective numbers. Isn't 362.0mL and 362mL the same thing?
You get lost and stop at a gas station to ask for directions. The attendant tells you that your destination is "about 1 mile down the road". You drive to your destination, but you notice that, according to your trip odometer, you have driven 1.9 miles. What was the % error in the attendant's distance estimate? ( Note: We will temporarily ignore the sign for error calculations. The correct answer for each calculation is an integerbetween 0 and 100, inclusive. Do NOT enter the percent sign (%) or a minus sign (-). )
Since 1 cubic cm= 1mL, then how many cubic cm are there in a liter?
