The steps of the solar system formation according to the nebula hypothesis will be 1,2,3,4,5,6,7.

<h3>What is solar system formation?</h3>

The solar system consists of the planet's satellites, as well as numerous comets, asteroids, and meteoroids, as well as the interplanetary medium.

The following are the steps to the nebular hypothesis. A nebula becomes a solar nebula when a patch of gas and dust within the cloud condenses into a core and becomes a protostar.

A nearby supernova blast might have created the condensing material. An accretion disc forms as the material surrounding the protostar falls.

The steps in the development of the solar system are as follows:

1. A giant nebula exists in space.

2. As the contraction continues a proto-star will form at the center which eventually becomes the star in the solar system

3. The contraction creates kinetic energy within the cloud

4. It begins to contract under its own gravity.

5. The entire nebula will flatten into a disk as a result and small back currents or eddies will form in the disk.

6. The cloud begins to heat up, flatten and spin or rotate.

7. Material builds up or accretes in eddies to form planets.

Hence, the steps of the solar system formation according to the nebula hypothesis will be 1,2,3,4,5,6,7.

A spring is compressed 8 cm. It is then brought back to equilibrium and compressed 24 cm. How much more work is done in the seco
posledela

Answer:

Nine times

Explanation:

x_{i} = Initial compression of the spring = 8 cm = 0.08 m

x_{f} = Final compression of the spring = 24 cm = 0.24 m

k = Spring constant of the spring

Initial spring energy is given as

U_{i} = (0.5) k x_{i}^{2}\\U_{i} = (0.5) k (8)^{2}\\U_{i} = 32 k

Initial spring energy is given as

U_{f} = (0.5) k x_{f}^{2}\\U_{f} = (0.5) k (24)^{2}\\U_{f} = 288 k = (9) (32) k = 9 U_{i}

A 3,65 kg mass attached to a
motikmotik

This question involves the concepts of tension, weight, and centripetal force.

The maximum speed, the mass can have before the string breaks is "10.26 m/s".

First, we will find the maximum tension force:

Tension = Weight

T = W = mg = (32.4 kg)(9.81 m/s²)

T = 317.84 N

Now, this tension force must be equal to the centripetal force:

T = \frac{mv^2}{r}\\v=\sqrt{\frac{Tr}{m}}

where,

v = maximum speed = ?

r = radius = 1.21 m

m = mass = 3.65 kg

Therefore,

v=\sqrt{\frac{(317.84\ N)(1.21\ m)}{3.65\ kg}}\\

<u>v = 10.26 m/s</u>

A machine puts out 6,000 J of work. To produce that much work the machine
topjm [15]

Answer:

Efficiency of the machine = 75%

Explanation:

Given:

Input work = 8,000 J

Output work = 6,000 J

Find:

Efficiency of the machine

Computation:

Efficiency of the machine = [Output work / Input work]100

Efficiency of the machine = [6,000 / 8,000]100

Efficiency of the machine = 75%
