B

b/c newtons third law of motion is: "For every action, there is an equal and opposite reaction."

5 0

Answer: Option (B) is the correct answer.

Explanation:

Newton's third law states that every action has an equal and opposite reaction.

For example, when we hit a ball with the help of a bat then the ball exerts an equal and opposite force on the bat.

Thus, we can conclude that out of the given options, the sentence if two objects collide, each object exerts a force equal to and in the opposite direction of the other states Newton's third law.

What are the foci of the ellipse given by the equation 100x^2 + 64y^2 = 6 400?
NikAS [45]

The equation of our ellipse is:

100 x^2 + 64 y^2 = 6400 (1)

First, let's reduce the equation of the ellipse to the standard form:

\frac{x^2}{a^2}+ \frac{y^2}{b^2}=1

To do that, we should divide both terms of equation (1) by 6400, and we get:

\frac{x^2}{64}+ \frac{y^2}{100}=1

This is a vertical ellipse (because b^2 \ \textgreater \  a^2) centered in the origin, and so the distance of its foci from the origin (on the y axis) is given by

c= \sqrt{b^2-a^2}= \sqrt{(100)-(64)}=6

Therefore, the position of the two foci is (0,6) and (0,-6)

when earth and moon are separated by a distance of 3.84×10^8 meters, the magnitude of the gravitational force of attraction betw
sammy [17]

The gravitational force would be 8\cdot 10^{20} N

Explanation:

The magnitude of the gravitational force between two objects is given by

F=G\frac{m_1 m_2}{r^2}

where

G=6.67\cdot 10^{-11} m^3 kg^{-1}s^{-2} is the gravitational constant

m1, m2 are the masses of the two objects

r is the separation between them

In this case, we can write the gravitational force between the Moon and the Earth as:

F=G\frac{M m}{r^2}

where M is the Earth's mass and m is the Moon's mass.

We know that:

r=3.84\cdot 10^8 m is their separation

F=2.0 \cdot 10^{20}N is the force between them

So we can find:

GMm = Fr^2 = (2.0\cdot 10^{20})(3.84\cdot 10^8)^2=2.95\cdot 10^{37} Nm^2

Now, we are asked to find the gravitational force when the Earth and the Moon are separated by

r'=1.92\cdot 10^8 m

In this case the new force would be

F'=G\frac{M m}{r'^2}

And substituting the values of (GMm) found previously and r', we find

F'=\frac{2.95\cdot 10^{37}}{(1.92\cdot 10^8)^2}=8\cdot 10^{20} N
