Mateo’s parents are thinking about investing money to help develop a new fusion power plant. Which issue is most important to co

nsider before making the investment?
a)Fusion has never been controlled, so how have they succeeded in doing it?
b)The fuel is quite limited, so have they discovered a more common fuel?
c)Fusion has been generating electricity for decades, so why build another fusion power plant?
d)Fusion requires high temperatures and pressures, so how have they reduced the energy cost for it?

Suppose you have two magnets. Magnet A doesn't have its poles labeled, but Magnet B does have a clearly labeled north and south
Levart [38]
<span>The right answer here would be option C - the side of Magnet A that's attracted to Magnet B's south pole must be Magnet A's north pole. This is due to the magnetic rule of opposites attracting.</span>

Train cars are coupled together by being bumped into one another. Suppose two loaded train cars are moving toward one another, t
Natasha_Volkova [10]

Answer:   0.137 m/s

Explanation:

from the question we are given the following

mass of train A (Ma) = 150,000 kg

velocity of train A (Va) = 0.3 m/s

mass of train B (Mb) = 95,000 kg

velocity of train B (Vb) = -0.12 m/s

final velocity (V) = ?

mass of both trains = 245,000 kg

  • to solve this question we apply the conservation of momentum

MaVa + MbVb = (Ma + Mb) x V

V = (MaVa + MbVb) /  (Ma + Mb)

V =  ((150,000 x 0.3) + (95,000 x (-0.12))) /  (245,000)

V = -33600 / 245,000

V = 0.137 m/s

The top of a swimming pool is at ground level. If the pool is 3.00 m deep, how far below ground level does the bottom of the poo
Yuri [45]

Answer:

a) 2.25 m

b) 2.625 m

Explanation:

Refraction is the name given to the phenomenon of the speed of light changing the the boundary when it moves from one physical medium to the other.

Refractive index is the ratio of the speed of light in empty vacuum (air is an appropriate substitution) to the speed of light in the medium under consideration.

In terms of real and apparent depth, the refractive index is given by

η = (real depth)/(apparent depth)

a) Real depth = 3.00 m

Apparent depth = ?

Refractive index, η = 1.333

1.333 = 3/(apparent depth)

Apparent depth = 3/1.3333 = 2.25 m.

Hence the bottom of the pool appears to be 2.25 m below the ground level.

b) Real depth = 1.5 m

Apparent depth = ?

Refractive index, η = 1.333

1.3333 = 1.5/(apparent depth)

Apparent depth = 1.5/1.3333 = 1.125 m

But the pool is half filled with water, there is a 1.5 m depth on top of the pool before refraction starts.

So, apparent depth of the pool = 1.5 + 1.125 = 2.625 m below the ground level
