Answer:

Distance of Alpha century in miles = 25.279 *  10^{12}

Distance of Alpha century in Astronomical unit  = 2.719 * 10^5

Explanation:

Given

Distance of Alpha Centauri from the Solar System = 4.3 light year

Light year is the distance traveled by light in one year. Its a unit of measurement for distant celestial objects

One light year = 5.879 * 10^{12} miles

Total number of miles in 4.3 light years is equal to

4.3 * 5.879 * 10^{12}\\= 25.279 *  10^{12}

Distance of Alpha century in miles = 25.279 *  10^{12}

Number of astronomical units in one light year = 63241.1

Total number of astronomical units in 4.3 light years is equal to

4.3 * 63241.1\\= 2.719 * 10^5

Distance of Alpha century in Astronomical unit  = 2.719 * 10^5

mr Goodwill [35]

Answer:

Explanation:

a) Power consumption is 4100 J/min / 60 s/min = 68.3 W(atts)

work done raised the potential energy

b) 75(9.8)(1000) / (3(3600)) = 68.055555... 68.1 W

c) efficiency is 68.1 / 68.3 = 0.99593... or nearly 100%

Not a very likely scenario.

Imagine a system where a block rests on an inclined plane. The block is then given an initial push so that it starts sliding dow
Helen [10]

Answer:

statement - 'The work done by friction is equal to the sum of the work done by the gravity and the initial push' is correct.

Explanation:

The statement ''The work done by friction is equal to the sum of the work done by the gravity and the initial push" is correct.

The above statement is correct because, the initial push will tend to slide down the block thus the work done by the initial push will be in the downward direction. Also, the gravity always acts in the downward direction. thus, the work done done by the gravity will also be in the downward direction

here, the downward direction signifies the downward motion parallel to the inclined plane.

Now we know that the work done by the friction is against the direction of motion. Thus, the friction force will tend to move the block up parallel to the inclined plane.

Hence, for the block to stop sliding the the above statement should be true.
