The following lists of
stars in order from least density to greatest density are giant, main sequence
star, white dwarf, neutron star. The answer is letter B. Aside from neutron
star being the densest star, it is also the smallest star compared to the giant
star, as its name implied.

Answer:
Explanation:
average speed is distance traveled over time
v = (50 + 30(1.5)) / (2 + 1.5) = 27.1428571...
v = 27 km/hr
The value of the spring constant of the spring is 14.7 N/m.
The given parameters;
- <em>mass attached to the spring, m = 30 g</em>
- <em>length of the spring, L₀ = 10 cm</em>
- <em>angular speed of the mass = 90 rpm</em>
- <em>final length of the spring, L₁ = 12 cm</em>
The extension of the spring is calculated as follows;

The value of the spring constant of the spring is calculated by applying Hooke's law;

Answer:
Float
Explanation:
It is given that,
The density of water is 1 g/mL
The density of a rock is 0.87 g/mL
It can be seen that the density of water is more than that of rock. The density of an object is calculated from its mass and volume.
If the density of liquid in which it is placed, is more that that of the object, it will float at the top.
Hence, in this case the rock will float.
