Hey there,

Your question states: <span>How long does it take for light from a star that is 8 light-years away to reach earth?

It take just about (</span>8 earth years) <span> for light from a star that is 8 light-years away to reach earth. That is how </span>FAST it would take.

Hope this helps.

Represent 7468 N with SI units having an appropriate prefix. Express your answer to four significant figures and include the app
sergeinik [125]

Answer:

7.468 kN

Explanation:

Here the force of 7468 Newton is given.

Some of the prefixes of the SI units are

kilo = 10³

Mega = 10⁶

Giga = 10⁹

The number is 7468.0

Here, the only solution where the number of significant figures is kilo

1 kilonewton = 1000 Newton

1\ Newton=\frac{1}{1000}\ kilonewton

\\\Rightarrow 7468\ Newton=\frac{7468}{1000}\ kilonewton\\ =7.468\ kilonewton

So 7468 N = 7.468 kN

A 25.0 kg object moving at +15.0 m/s strikes a 15.0 kg
lesya692 [45]

The final velocity of the 15 kg mass is 18.33 m/s.

<h3>Conservation of linear momentum</h3>

The final velocity of the 15 kg mass can be determined by applying the principles of conservation of linear momentum as follows;

m_1 u_1 + m_2 u_2 = m_1 v_1 + m_2 v_2\\\\

Where;

  • m₁ is the mass of the first object = 25 kg
  • u₁ is the initial velocity of the first object = 15 m/s
  • m₂ is the mass of the second object = 15 kg
  • u₂ is the initial velocity of the second object = -10 m/s
  • v₁ is the final velocity of the first object = -2 m/s
  • v₂ is the final velocity of the second object

Thus, the final velocity of the 15 kg mass after the collision is 18.33 m/s.

Of the following approximate conversions of celsius into fahrenheit, which is most accurate? a. 24°c almost-equals 75.9°f b. 2°c
Softa [21]

The most accurate among the options is 13°c almost-equals 55.0°f, when you round down 55.4, you get 55.0

Hence, option D) is the most accurate.

<h3>What is Scale of Temperature?</h3>

Scale of temperature is simply a method used in calibrating the physical quantity of temperature in metrology.

Conversion of Celsius into Fahrenheit, Formula is expressed as;

Degree = (0 × 9/5) + 32 = Fahrenheit

First we check each option;

A) 24°c almost-equals 75.9°f

24°C = (24 × 9/5) + 32 = 75.2°F

B) 2°C almost-equals 35.8°f

2°C = (2 × 9/5) + 32 = 35.6°F

C) 34°C almost-equals 92.7°f

34°C = (34 × 9/5) + 32 = 93.2°F

D) 13°c almost-equals 55.0°f

13°C = (13 × 9/5) + 32 = 55.4°F

The most accurate among the options is 13°c almost-equals 55.0°f, when you round down 55.4, you get 55.0

Hence, option D) is the most accurate.

Why are political parties created?
Alja [10]
Political parties are composed of people who share views as to how a new government should be run. There are multiple political parties because politicians all have different views or focuses if they were to be included in the new government.
