Answer:
No
Explanation:
Betelgeuse has a diameter around 700 times the size of our sun…. like possibly as far as the orbit of Jupiter. It is known as a red supergiant and around 100,000 times brighter than our sun. Betelgeuse is at the very end of its life.
Answer:
If you look at the night sky different
times of the year you see different
constellation.This change due to the
motion of the earth in it's orbit around
the sun.The shift of the sky is really
the motion of the earth around the sun.

Answer:
118 elements
Explanation:
Of these 118 elements, 94 occur naturally on Earth.
n = number of mole of sample of helium gas = 7.16 x 10⁻⁴ moles
T = temperature of the gas = temperature of the bulb ?
V = Volume of helium gas = 75 mL = 7.5 x 10⁻⁵ m³
P = pressure of the helium gas = 116.8 kPa = 116.8 x 10³ Pa (1 k = 1000)
Using the equation
P V = n R T
inserting the values
(116.8 x 10³) (7.5 x 10⁻⁵) = (7.16 x 10⁻⁴) (8.314) T
T = 1471.6 C
Answer:
1.5M
Explanation:
Molarity = moles/volume
0.60 mol / 0.40 L = 1.5 M
