E=mc^2 n its given 1kg = 9x10^16J
so need to figure out the total mass loss n u can find the energy released
mass loss when 4x H atom combines to form 1x He atom in a fusion reaction is given as 4.59x10^-29kg
1 mole of He has 6.02x10^23 He atoms
so 2.7 moles of He has 2.7x6.02x10^23 He atoms
the total mass loss for 2.7 moles of He created in a fusion reaction
= 2.7x6.02x10^23 x 4.59x10^-29kg
= 7.46x10^-5kg
radiation energy released from this fusion reaction
= 7.46x10^-5 x 9x10^16J
= 6.7x10^12J
its 60 BILLION times more than burning carbon!!
Answer: In particular, electron degeneracy pressure is what supports white dwarfs against gravitational collapse, and the Chandrasekhar limit (the maximum mass a white dwarf can attain) arises naturally due to the physics of electron degeneracy.

Answer and Explanation:
The texture of the slabs affects the type of bonding the water molecules has with each other.
The dry glass slab allows the water to form cohesive bonds with each other, making the water stick to itself and not the slab, which makes it flow uniformly, or regularly.
The Waxed glass slab has a different texture that forms an adhesive-type bonding with water, making the water stick to the slab at certain parts/forming the spherical droplets.

Answer:
Explanation:
Density can be found by dividing the mass by the volume.
The mass is 5.28 grams and the volume is 2 cubic centimeters.
Substitute the values into the formula.
Divide.
The density of the unknown substance is 2.64 grams per cubic centimeter.
The density of a diamond is about 3.5 grams per cubic centimeter. Since 2.64 is not equal to 3.5, the unknown substance is not a diamond.

As = 360*(2.5) / 3.0 min (60)
As = 900 deg / 180 s
