The Sun gives off energy, and that energy can be found deep in it's core, the Sun is busily converting mass into energy. According to Einstein equation of mass and energy equivalence, from his very famous equation E = mc².
Given: Energy E = 3.6 X 10²⁶ J
Speed of light c = 3.00 x 10⁸ m/s
Required: Mass m loss by the sun each second
Formula: E = mc² derive for mass m
m = E/c²
m = 3.6 x 10²⁶ Kg.m²/s² or J/(3.00 X 10⁸ m/s)²
m = 4 x 10⁹ Kg or the Sun is loosing
m = 4 million tons of mass each second
Answer:
If you meant the Periodic Table it's the alkaline-earth metal
beryllium (Be)

calcium (Ca)
strontium (Sr)
barium (Ba)
radium (Ra)
Explanation:
Answer:
40,000N of force
Explanation:
The formula for force is F=ma. If we plug in the values, F=(20,000kg)(2m/s^2).
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
Answer:
The stones are apart one each the other 26.37 meters when the second one has reached a speed of 14 m/s.
Explanation:
<u>Second Stone:</u>
Vb= g*t
tb (14m/s)= Vb/g
tb (14m/s)= (14 m/s) / (9.8 m/s²)
tb (14m/s)= 1.42 sec
Hb= (g * tb²)/2
Hb= 9.88m
<u>First Stone:</u>
ta= tb + 1.3 sec
ta= 2.72 sec
Ha= (g*ta²)/2
Ha= 36.25m
Distance between Stones:
Ha-Hb= 36.25m - 9.88m
Ha-Hb= 26.37m
