The earth has about 80 times the mass of the earth's moon. The gravitational force exerted on the moon by the earth has what rel
chubhunter [2.5K]

Answer:

Both forces are the same.

Explanation:

The problem states that:

m_e = 80*m_m

The force exerted on the moon by earth is given by:

F_m=\frac{K*m_e*m_m}{d^2}   where K is the gravitational constant, and d is the separation distance between the earth and the moon.

The force exerted on the earth by moon is given by:

F_e=\frac{K*m_m*m_e}{d^2}   where K is the gravitational constant, and d is the separation distance between the earth and the moon.

The relation is therefore:

F_m/F_e = \frac{K*m_e*m_m/d^2}{K*m_m*m_e/d^2}=1

As you can see, they are the same.

Two vectors A and B are added to give a resultant R. The components of A are Ax = -8.0 units and Ay = 6.0 units and the componen
Georgia [21]

Answer:

<em>10.09 units</em>

Explanation:

For the A

Ax = -8.0 units

Ay = 6.0 units

The resultant vector = Ra = \sqrt{A^2_{x} + A^2_{y}  }

Ra = \sqrt{(-8)^2 + 6^2  } =  10 units

For B

Bx = 1.0 units

By = -1.0 units

The resultant vector = Rb = \sqrt{B^2_{x} + B^2_{y}  }

Rb = \sqrt{1^2 + (-1)^2  } = \sqrt{2} units

Adding these two vectors A and B together, magnitude of vector R is

R = \sqrt{R^2_{a} + R^2_{b}  }

R =  \sqrt{10^2 + (\sqrt{2} ) ^2} = <em>10.09 units</em>
