Answer:
A) a scientific theory or principle
Explanation:
A Theory or principle has to explain different observations for a specific phenomenon. Theories are tested in base of new data to see if they can fit with all the new variations. They gain more acceptance in the scientific world if they predict in a correct way the result of many observations.
For example the uncertainty principle which state that the position and the momentum of a particle can not be known at the same time. Many experiments that aim to test the Uncertainty principle demonstrated this property, but tests are currently being done with other variations to see if the principle still fits with them.
Answer:
Tides on our planet are caused by the gravitational pull of the Moon and Sun. Earth's oceans "bulge out" because the Moon's gravity pulls a little harder on one side of our planet (the side closer to the Moon) than it does on the other. The Sun's gravity raises tides, too, but lunar tides are twice as big.
Answer:
Continuous random variable
Explanation:
The distance that baseball travels after being hit is a random variable and it assume any real value defined on the sample space.
The distance is measurable and thus is continuous random variable because continuous variable cannot be counted but could be measured.
Answer:
10.895 m
Explanation:
v = Velocity
g = Acceleration due to gravity = 9.81 m/s²
h = Height of waterfall = 5 m
Distance traveled by an object which has forward velocity is given by
![R=\dfrac{v}{\sqrt{\dfrac{2h}{g}}}\\\Rightarrow R=\dfrac{15}{\sqrt{\dfrac{2\times 5}{9.81}}}\\\Rightarrow R=14.85681\ m](https://tex.z-dn.net/?f=R%3D%5Cdfrac%7Bv%7D%7B%5Csqrt%7B%5Cdfrac%7B2h%7D%7Bg%7D%7D%7D%5C%5C%5CRightarrow%20R%3D%5Cdfrac%7B15%7D%7B%5Csqrt%7B%5Cdfrac%7B2%5Ctimes%205%7D%7B9.81%7D%7D%7D%5C%5C%5CRightarrow%20R%3D14.85681%5C%20m)
![R=\dfrac{v}{\sqrt{\dfrac{2h}{g}}}\\\Rightarrow R=\dfrac{26}{\sqrt{\dfrac{2\times 5}{9.81}}}\\\Rightarrow R=25.75181\ m](https://tex.z-dn.net/?f=R%3D%5Cdfrac%7Bv%7D%7B%5Csqrt%7B%5Cdfrac%7B2h%7D%7Bg%7D%7D%7D%5C%5C%5CRightarrow%20R%3D%5Cdfrac%7B26%7D%7B%5Csqrt%7B%5Cdfrac%7B2%5Ctimes%205%7D%7B9.81%7D%7D%7D%5C%5C%5CRightarrow%20R%3D25.75181%5C%20m)
The distance between them is 25.75181-14.85681 = 10.895 m
