1 answer:

6 0

The source of power in a nuclear power plant is nuclear reactors. These reactors split uranium atoms, releasing energy in the form of heat, in a process called fission. The heat converts water into steam which powers a turbine generator to produce electricity.

Let r denote the distance between the center of the earth and the center of the moon. What is the magnitude of the acceleration

stepan [7]

Answer:

The magnitude of the acceleration ae of the earth due to the gravitational pull of the moon is $\mathbf{3.3187\times10^{-5}}\frac{m}{s^{2}}$

Explanation:

By Newton's gravitational law, the magnitude of the gravitational force between two objects is:

$F=G\frac{Mm}{r^{2}}$ (1)

With G the gravitational constant, M the mass of earth, m the mass of the moon and r the distance between the moon and the earth, a quick search on physics books or internet websites give us the values:

$M=5.972\times10^{24}\,kg$

$m=7.34767309\times10^{22}\,kg$

$r=384400\,km$

$G=6.674\times10^{-11}\,\frac{N\,m^{3}}{kg^{2}}$

Using those values on (1)

$F=(6.674\times10^{-11})*\frac{(5.972\times10^{24})(7.34767309\times10^{22})}{(384400\times10^{3})^{2}}$

$F\approx1.98193\times10^{20}N$

Now, by Newton's second Law we can find the acceleration of earth ae due moon's pull:

$F=M*ae\Longrightarrow ae=\frac{F}{M}=\frac{1.98193\times10^{20}}{5.972\times10^{24}}\approx\mathbf{3.3187\times10^{-5}}$

The gravitational field on Saturn is 10.4 times its value on Earth.

nalin [4]

The weight of 100 kg mass on Saturn is 10,192 N.

The weight of 7.0 kg mass on Pluto is 2.01 N.

The given parameters;

<em>acceleration due to gravity, = 10.4g</em>
<em>mass of the Saturn, m = 100 kg</em>
<em>acceleration due to gravity on mercury, = 3.59 m/s²</em>

The weight of 100 kg mass on Saturn is calculated as follows;

W = mg

W = 100 x 10.4 x 9.8

W = 10,192 N

The weight of 7.0 kg mass on Pluto is calculated as follows;

W = 7 x 0.08 x 3.59

W = 2.01 N

A marble dropped in still water will create circular ripples or waves. the radius of each circular wave will increase 4 centimet

Gnom [1K]

The circumference of the circle after t seconds = 25.12 t

Given data,

The radius of each circular wave will increase by four centimeters per second (cm/s)

In 1 second of circular wave radius = 4cm

In 1*t second of circular wave radius = 4t cm

As a result, the radius of the circular wave after t seconds is 4t cm.

We already know that the circumference of a circle is given by = 2πr, where r is the circle's radius.

As a result, the radius of a circular wave after t seconds is = 2π * radius of a circular wave after t seconds = 2π * 4t

= 8πt

( Taking π = 3.14 )

As a result, the circumference of the circle after t seconds = 8πt

= 3.14t

= 25.12t
