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:
Explanation:
which is the final velocity minus the initial velocity in the numerator, and the change in time in the denominator. For us:
so
a = .92 m/s/s (NOT negative because you're speeding up)
Answer:
they become ionized and change to ions
Answer:
65 m/s
Explanation:
The motion of the supply along the horizontal direction is a uniform motion with constant speed. Therefore, its horizontal velocity is given by
![v=\frac{d}{t}](https://tex.z-dn.net/?f=v%3D%5Cfrac%7Bd%7D%7Bt%7D)
where
d is the distance travelled horizontally
t is the time taken
In this problem, d = 650 m and t = 10 s, so if we apply the formula we get
![v=\frac{650 m}{10 s}=65.0 m/s](https://tex.z-dn.net/?f=v%3D%5Cfrac%7B650%20m%7D%7B10%20s%7D%3D65.0%20m%2Fs)
Answer:
The acceleration due to gravity at Pluto is 0.0597 m/s^2.
Explanation:
Length, L = 1 m
10 oscillations in 257 seconds
Time period, T = 257/10 = 25.7 s
Let the acceleration due to gravity is g.
Use the formula of time period of simple pendulum
![T = 2\pi\sqrt{\frac{L}{g}}\\\\25.7 = 2 \times 31.4\sqrt{\frac{1}{g}}\\\\g = 0.0597 m/s^2](https://tex.z-dn.net/?f=T%20%3D%202%5Cpi%5Csqrt%7B%5Cfrac%7BL%7D%7Bg%7D%7D%5C%5C%5C%5C25.7%20%3D%202%20%5Ctimes%2031.4%5Csqrt%7B%5Cfrac%7B1%7D%7Bg%7D%7D%5C%5C%5C%5Cg%20%3D%200.0597%20m%2Fs%5E2)
