Two stars that are in the same constellation:
Kitty [74]

Answer:

C

Explanation:

Constellations are stellar patterns which are made out of bright stars which appears close to each other and can form a recognisable pattern.

But that does not mean these stars are actually close to each other. The sky that we see from Earth appears as a 2D representation of a 3D Space. If you look in a particular direction in sky you will see all the stars in that direction irrespective of their actual distance from the Earth and hence these stars can be practically very far from each other too.

A mass hanging from a spring oscillates with a period of 0.35 s. Suppose the mass and spring are swung in a horizontal circle, w
Annette [7]

Answer:

66 rpm

Explanation:

The period of oscillation is given by

T=2\pi \sqrt{\frac {m}{k}}

\frac {k}{m}=\frac {4\pi^{2}}{T^{2}} where  T is time period of oscillation which is given as 0.35 s, k s spring constant and m is the mass of the object attached to the spring.

Also, net force is given by

Net force=m\omega^{2} L

\omega=\sqrt{\frac {k\triangle L}{mL}} where \triangle L is the elongation, L is original length, \omega is the angular velocity

Substituting the equation of \frac {k}{m} into the above we obtain

\omega=\sqrt {\frac {4\pi^{2}\triangle L}{T^{2} L}}

\omega=\sqrt {4\pi^{2}\times 0.15L}{0.35^{2}\times L}}=6.952763\approx 6.95 rad/s

6.95\times\frac {60 s}{2\pi rad}\approx 66 rpm

Larry average 23 points per game how many points does he need to score in the last game to have an average of 25 points per game
Lapatulllka [165]

Answer:

Sample Response: Multiply 5 by 25 to find the total points Larry needs to score in 5 games. 5 x 25 = 125. Then find the total points Larry scored in the first 4 games. 4 x 23 = 92. Subtract to find the number of points Larry needs to score in the fifth game. 125 – 92 = 33 points. Larry needs to score 33 points in the last game.
