Explanation:

It is given that

The kinetic energy of  Mr. Thomson’s prius, K = 641300 J

He is moving with a velocity, v = 22 m/s

It is required to find the mass of Mr. Thomson’s prius.

Due to his motion, a kinetic energy will possess by him. The mathematical form of kinetic energy is given by :

K=\dfrac{1}{2}mv^2

Solving for m

m=\dfrac{2K}{v^2}

Plugging all the values, we get :

m=\dfrac{2K}{v^2}\\\\m=\dfrac{2\times 641300}{(22)^2}\\\\m=2650\ kg

So, the mass of Mr. Thomson’s prius is 2650 kg.

A fluid in an aquifer is 23.6 m above a reference datum, the fluid pressure (in gage pressure) is 4390 n/m2 and the flow velocit
Phoenix [80]

As per Bernuolli's Theorem total energy per unit mass is given as

\frac{P}{\rho} + \frac{1}{2}v^2 + gH = E

now from above equation

P = 4390 N/m^2

\rho = 0.999 * 10^3

v = 7.22 * 10^{-4} m/s

H = 23.6 m

now by above equation

\frac{4390}{0.999*10^3} + \frac{1}{2}*(7.22*10^{-4})^2 + 9.8*23.6 = E

E = 235.7 J/kg

Part B)

Now energy per unit weight

U = \frac{E}{g}

U = \frac{235.7}{9.8}

U = 24 m

What is the correct definition of a hypothesis
Ira Lisetskai [31]
A scientific hypothesis is the initial building block in the scientific method. Many describe it as an "educated guess," based on prior knowledge and observation. ... A hypothesis also includes an explanation of why the guess may be correct, according to National Science Teachers Association.

<h2>Answer: Paths of the planets follow an elliptical orbit around the sun</h2>

Explanation:

Copernicus's model of the universe (heliocentric theory) was refuting the long life geocentric theory (the Earth as the center of the universe) proposed by Ptolemy and accepted by the Catholic Church.

However, the heliocentric theory did not explain why planets orbit the Sun at different speeds at different times, because<u> this model used only circular orbits. </u>

Years later, the astronomer Johannes Kepler refined the Copernicus' heliocentric theory with the introduction of <u>elliptical orbits</u> with the formulation of his three laws of planetary motion.

Where Kepler’s 1st Law is a clear example:

<em>The orbit of a planet around the Sun, is in the form of an ellipse with the Sun at one of the two foci of that ellipse. </em>
