Answer:
B) (-2.0 m, 0.0 m)
Explanation:
Given:
Mass of particle 1 is,
Mass of particle 2 is,
Position of center of mass is,
Position of particle 1 is,
Position of particle 2 is,
We know that, the x-coordinate of center of mass of two particles is given as:
Plug in the values given.
We know that, the y-coordinate of center of mass of two particles is given as:
Plug in the values given.
Therefore, the position of particle 2 of mass 3.0 kg is (-2.0 m, 0.0 m).
So, option (B) is correct.
Answer:
Copying materials from a source text, supplying proper documentation, but leaving out quotation marks
Explanation:
Plagiarism is when you take somebody's ideas and write them off as your own without giving them credit.
Answer:
V=27.24 m/s
Explanation:
We need to apply the linear momentum conservation theorem:
The velocity of the eagle its defined by its two components:
because speed is a scalar value:
I believe one of these are called Elliptical, Spiral, and Irregular Galaxies.
The correct answer is "3. Both increase"
In fact, the frequency of a vibrating string is given by
where L is the length of hte string, T the tension and
the linear mass density.
We can see that string is made shorter, L decreases, so the frequency f increases. And since the pitch has the same behaviour of the frequency, it increases as well.
