Answer:
Here:
Explanation:
So ionic bonds are formed due to electrostatic attraction. For example, in NaCl, Na gives an electron to Cl, getting Na+ and Cl- where + and - charges attract and form an ionic bond.
Answer:
waste energy = 30 J
Explanation:
Given that.
Input energy = 100 J
Useful energy = 70 J
We need to find the amount of waste energy.
Waste energy = total energy - used energy
= 100 J - 70 J
= 30 J
Hence, 30 J of energy is waste energy.
C) the nucleus. Hope this helps :)
Answer:
Helium and Ethlyene Oxide. Your answer is MASS.
Explanation:
Diffusion is faster at higher temperatures because the gas molecules have greater kinetic energy. effusion refers to the movement of gas particles through a small hole. Graham's law state's that the effusion rate of a gas is inversely proportional to the square root of the mass of its particles.
Answer:
Galileo performed a famous experiment where he used a ball rolling on a ramp (inclined plane) to study the motion of objects under the influence of gravity. The ramp allowed him to make more precise measurements because the ball moved more slowly along the ramp than if it were simply dropped. Galileo discovered through this experiment that the objects fell with the same acceleration, proving his prediction true, while at the same time disproving Aristotle's theory of gravity (which states that objects fall at speed proportional to their mass). Galileo's conclusion from this thought experiment was that no force is needed to keep an object moving with constant velocity. Newton took this as his first law of motion. One result of the experiment surprised Galileo, and one surprises us. Galileo found that the heavy ball hit the ground first, but only by a little bit. Except for a small difference caused by air resistance, both balls reached nearly the same speed. And that surprised him. According to history, Galileo’s experiment on falling bodies largely contributed to Isaac Newton’s Law of Gravity. In Galileo’s experiment, he is said to have dropped balls from the Leaning Tower of Pisa. The balls were made of the same material but had different masses. Galileo set out to prove that the time it took for these objects to reach the ground would be the same. Galileo proved that objects reached the ground at the same time,
