The radius of Earth is 6.37 x 10° m. The average Earth-Sun distance is 1 496 x 1011 m. How many Earths would fit between Earth and the Sun if they are separated by their average distance? Use an order-of-magnitude calculation to estimate this
number. Then, determine an exact answer and express it in scientific notation with the correct number of significant digits.

d

explanation:

v=uf/(u-f)

= 5.10/(5-10) convex lens has positive focal length

=50/-5

=-10 cm (formed at other side)

the duration of a photographic flash is related to an rc time constant, which is 0.100 μs for a certain camera.

god i hope this !

= initial pressure

= final pressure = 2

= initial volume

= final volume = /4

= initial temperature = 20 c = 20 + 273 = 293 k

= final temperature = ?

using the equation
