A: the type of plant
B: how tall the plant is
The statement is false because as the temperature of water is decreased from 4C to 0C, <em>expansion</em> occurs.
You should understand that this is very weird behavior for any compound ... within a small temperature range, the stuff actually gets bigger as it gets colder. That's why cubes float in your sody, and bergs float in the ocean.
Water is one of only two known substances that do this. And if water didn't do it, then life on Earth would not be possible.
Hmmm....
Answer and Explanation:
The law of conversation of energy states that energy cannot be created or destroyed. The pendulum slows down and stops eventually not because the kinetic energy is destroyed, but it is transferred into sound and heat energy instead because there is air resistance and friction.
Kinetic energy => Gravitational potential energy (Loop but some energy transferring to heat and sound each time)
Answer:
An object appears white when it reflects all wavelengths and black when it absorbs them all. Red, green and blue are the additive primary colors of the color spectrum. Combining balanced amounts of red, green and blue lights also produces pure white.
Explanation:
Answer:
1.31022×10⁻³⁴ kg
Explanation:
Difference in energies = 1189.4-1115.7 MeV = 73.7 MeV
Convert this energy to Joules
1 MeV = 1.6×10⁻¹⁹ J
73.7 MeV = 73.7×1.6×10⁻¹⁹ J = 117.92×10⁻¹⁹ J
c = Speed of light = 3×10⁸ m/s
From Einstein's equation
E = mc²

∴ Difference in their masses is 1.31022×10⁻³⁴ kg
