The answer is
6.67 Ohms (I tried to find the ohms sign but it looks like the lululemon logo)
Answer:
<em>The resultant velocity has a magnitude of 38.95 m/s</em>
Explanation:
<u>Vector Addition</u>
Given two vectors defined as:
The sum of the vectors is:
The magnitude of a vector can be calculated by
Where x and y are the rectangular components of the vector.
We have a plane flying due west at 34 m/s. Its velocity vector is:
The wind blows at 19 m/s south, thus:
The sum of both velocities gives the resultant velocity:
The magnitude of this velocity is:
d = 38.95 m/s
The resultant velocity has a magnitude of 38.95 m/s
A model would be useful for a scientist because it allows prediction of what may happen without doing really the experiments. It saves time and money for the scientist. Also, it helps scientists in communicating their <span>scientific investigation to people.</span>
The universal law of gravitation says that the gravitational force between the two masses is
<em>F</em>₁ = <em>G</em> <em>m</em>₁ <em>m</em>₂ / <em>r</em> ² = 6.0 × 10⁻⁶ N
where <em>r</em> = 12 m. When the distance between the two masses is reduced to <em>R</em> = 4 m, i.e. 1/3 of the original distance <em>r</em>, we have
<em>F</em>₂ = <em>G</em> <em>m</em>₁ <em>m</em>₂ / <em>R </em>² = <em>G</em> <em>m</em>₁ <em>m</em>₂ / (<em>r</em>/3)² = 1/9 <em>G</em> <em>m</em>₁ <em>m</em>₂ / <em>r </em>² = 1/9 <em>F</em>₁
so that the resulting gravitational force has 1/9 the first magnitude, or
<em>F</em>₂ = 1/9 (6.0 × 10⁻⁶ N) ≈ 6.7 × 10⁻⁷ N
