Answer:

v=0.04m/s

Explanation:

To solve this problem we have to take into account the expression

\omega=\frac{v}{r}

where v and r are the magnitudes of the velocity and position vectors.

By calculating the magnitude of r and replacing w=0.02rad/s in the formula we have that

|r|=\sqrt{(-1.18m)^2+(-0.9m)^2}=2.01m\\\\v=\omega r=(0.02\frac{rad}{s})(2.01m)=0.04\frac{m}{s}

the maximum relative velocity is 0.04m/s

hope this helps!!

Answer:

The maximum relative velocity = 0.0296m/s

Explanation:

Data Given;

angular velocity = 0.02rad/s

r = -1.8m and -0.9m

To calculate the relative velocity, we use the formula;

<h3>v = wr-------------------------------1</h3>

where;

v = Linear velocity

w = angular velocity

r = radius

from the question, the resultant radius is calculated as;

r = √rx² + ry²

   =√ (-1.18² + -0.9²)

  =√(1.3924 +0.81)

   =√2.2024

r   = 1.48m

Substituting the values into equation 1, we have

<h3>v = wr</h3><h3> = 0..02 * 1.48</h3><h3> = 0.0296m/s</h3>

The angular separation of two stars is 0.1 arcseconds and you photograph them with a telescope that has an angular resolution of
gizmo_the_mogwai [7]

Answer:

Will see them as only one star

Explanation:

Solution:

- The angular resolution of a telescope means the minimum quantity that can be visualized. Since their angular separation ( 0.1 arcseconds ) is smaller than the telescope's angular resolution (1 arcseconds ), your photograph will seem to show only one star rather than two.

I know that the relationship between altitude and atmospheric density is that the higher the altitude, the lesser the density, and the lower the altitude the higher the density. Lower density float to the top, and higher density is 'heavy' so it comes down
