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,

<u>Answer:</u> The equilibrium molarity of oxygen gas is 7.1 M
<u>Explanation:</u>
We are given:
Moles of oxygen gas = 1.3 mole
Moles of NO = 1.5 moles
Volume of the flask = 250 mL = 0.250 L (Conversion factor: 1 L = 1000 mL)
To calculate the molarity, we use the equation:
Molarity of oxygen gas = 
Molarity of NO = 
The chemical equation follows:
Initial: 5.2 - 6.0
At eqllm: 5.2+x +x 6.0-2x
The expression of 
for above equation follows:
![K_c=\frac{[NO]}{[O_2][N_2]}](https://tex.z-dn.net/?f=K_c%3D%5Cfrac%7B%5BNO%5D%7D%7B%5BO_2%5D%5BN_2%5D%7D)
(Assuming)
Putting values in above equation, we get:
Neglecting the value of x = 5.4 because this cannot be greater than the initial value.
Concentration of oxygen gas at equilibrium = (5.2 + x) = 5.2 + 1.9 = 7.1 M
Hence, the equilibrium molarity of oxygen gas is 7.1 M
Answer:
500kg.
Explanation:
Newton's Second Law relates force, mass and acceleration to one another through the equation:
F = ma
We can rearrange this equation algebraically to solve for mass:
m = F/a
Substituting our known values for the variables, we get:
m = 1500N/3m/s2
So mass of the object is 500kg.
We know it's kg because Newtons (N) are a unit defined as 1 kg/m/s2, so m/s2 cancels out when we divide :)
Answer:
I think it's the state of the surrounding water because if the water holds impurities it will float and if it doesn't have impurities it will sink
