True. Also stretches shoulders and other things
answer
v = 4.2
set up an equation
we can use the formula for kinetic energy since we know mass and kinetic energy
K =
v =
values
K = 0.013 J
m = 1.5g = 0.0015 kg
plug in values
v =
v = 4.2
Answer:
a. The Sun is 110.24 cm.
b. The distance of the nearest star at 4.24 light years is 3.1586 × cm.
Explanation:
Given a scale :
12700 Km : 1 cm
a. How large is the Sun of diameter 1.4 × Km?
Thus using the given scale, we have to compare the diameter of the Sun to that of the Earth.
=
= 110.2362
The Sun is 110.24 cm.
b. how far away is the nearest star at a distance of 4.24 light-years on this scale?
A light year is a term that is used to express the total distance that light would travel in an empty space in a year.
One light year = 9.461 × Km
So that,
4.24 light years = 4.24 × 9.461 × Km
= 40.11464 × Km
Using the given scale,
= 3.1586 ×
The distance of the nearest star at 4.24 light years is 3.1586 × cm.
Answer:
When the Moon passes between Sun and Earth, the lunar shadow is seen as a solar eclipse on Earth. When Earth passes directly between Sun and Moon, its shadow creates a lunar eclipse. Lunar eclipses can only happen when the Moon is opposite the Sun in the sky, a monthly occurrence we know as a full Moon.
