Answer: d) The bulging center of a spiral galaxy consisting of stars in the shape of a flattened sphere that circles a black hole

Explanation:

Bulge is part of star at the center where stars are closely packed. Most of the spiral galaxies have Bulge at their heart that is at their center. The shape of a bulge resembles that of a flattened sphere. Most of the bulges have high compact mass at their center about which the stars rotate. This high compact mass at the center is assumed to be super-massive black-hole.

Thus, a nuclear bulge can be defines as: d) The bulging center of a spiral galaxy consisting of stars in the shape of a flattened sphere that circles a black hole

FORCE AND DISPLACEMENT AT AN ANGLE A sailor pulls a boat a distance of 30.0 m along a dock using a rope that makes a 25.0° angle

Bingel [31]

Answer: 6117.58 J

Explanation:

We know that W=Fd*cos(theta) where theta is the angle between the displacement and the force.

In this case, we are given that F=225 N, d=30 m, and theta=25 degrees.

Plugging all this in we get

W=225*30*cos(25)=6117.58 J

a 4kg block is attatched to a vertical sspring constant 800n/m. the spring stretches 5cm down. how much elastic potential energy

kow [346]

The Potential energy stored in the system is 1 J

Explanation:

Given-

Mass, m = 4 kg

Spring constant, k = 800 N/m

Distance, x = 5cm = 0.05m

Potential energy, U = ?

We know,

Change in potential energy is equal to the work done.

So,

$U = \frac{1}{2} k (x)^2\\\\$

By plugging in the values we get,

$U = \frac{1}{2} * 800 * (0.05)^2\\ \\U = 400 * 0.0025\\\\U = 1J\\$

Therefore, Potential energy stored in the system is 1 J
