Answer:

False

Explanation:

The two population of stars in our galaxy are nowhere near similar in many characteristics.

For instance, the stars in the milky way galaxy are about 2/3 of all observable stars. Yes, the populations of stars in the milky way and outside of it are both large, but the population in the milky way galaxy is double that of elsewhere.

<h3>Answer:a) Distance= 240m. b) Displacement= 90m. c) Average Speed= 5 $ms^{-1}$ . d) Average Velocity= 1.875 $ms^{-1}$ </h3>

Explanation:

a) Distance ➤ (80+50+70+40) m. ➤ Distance= 240m.

b) Displacement ➤ (50+40)m. ➤ Displacement= 90m

c) Average Speed ➤ Total distance travelled/total time taken

➤ 240/48

➤ 5 $ms^{-1}$

d) Average Velocity ➤ Total displacement/total time taken

➤ 90/48

➤ 1.875 $ms^{-1}$

At which position is the kinetic energy of a particle executing SHM greatest?

Over [174]

Explanation:

The kinetic energy of a particle in SHM is given by :

$K=\dfrac{1}{2}m\omega^2(A^2-x^2)$

Where

m is the mass of a particle

A is the amplitude

x is the distance

$\omega$ is the angular frequency

The kinetic energy of a particle executing SHM is maximum at its equilibrium position and minimum at a maximum displacement from the equilibrium point.
