Elliptical and Spiral have some similarities, they both are huge and contain lost of dust and also they are held by gravitational forces.

<u>Answer:</u> The correct statement is both are held together by gravitational forces.

<u>Explanation:</u>

Galaxies are defined as the system which contain millions or billions of stars bind together by gas or dust and held together by gravitational forces.

There are three types of galaxies: elliptical, spiral and irregular shaped. All the galaxies have different shapes of centers. Some may have elongated centers, some can shape like bars.

The galaxies do not change their shape from time to time. Minor changes might be seen but change is shape does not happen.

Hence, the correct statement is both are held together by gravitational forces.

Please HELP ME If the motion of an object changes, what must be true about the forces acting on that object?
atroni [7]

Answer:

If there is a net force acting on an object, the object will have an acceleration and the object's velocity will change. ... Newton's second law states that for a particular force, the acceleration of an object is proportional to the net force and inversely proportional to the mass of the object.

An alternative to CFL bulbs and incandescent bulbs are light-emitting diode (LED) bulbs. A 16-W LED bulb can replace a 100-W inc
Yanka [14]

Answer:

LED bulb = 0.145 A

Incandescent bulb = 0.909 A

CFL bulb = 0.218 A

Explanation:

Given:

Power rating of LED bulb (P₁) = 16 W

Power rating of incandescent bulb (P₂) = 100 W

Power rating of CFL bulb (P₃) = 24 W

Terminal voltage across the circuit (V) = 110 V

We know that, power is related to terminal voltage and current drawn as:

P=VI

Express this in terms of 'I'. This gives,

I=\frac{P}{V}

Now, calculate the current drawn in each bulb using their respective values.

For LED bulb, P_1=16\ W, V=110\ V

So, current drawn is given as:

I_1=\frac{16\ W}{110\ V}=0.145\ A

For incandescent bulb, P_2=100\ W, V=110\ V

So, current drawn is given as:

I_2=\frac{100\ W}{110\ V}=0.909\ A

For CFL bulb, P_3=24\ W, V=110\ V

So, current drawn is given as:

I_3=\frac{24\ W}{110\ V}=0.218\ A

Therefore, the currents drawn through LED bulb, incandescent bulb and CFL bulb are 0.145 A, 0.909 A and 0.218 A respectively.
