4 0

Answer:

KE = 1/2mv^2

KE = 1/2(1120)(40^2)

KE = 560(1600)

KE = 896000

Let me know if this helps!

BlackZzzverrR [31]

Answer:

The correct answer is B

Explanation:

To calculate the acceleration we must use Newton's second law

      F = m a

      a = F / m

To calculate the force we use the defined pressure and the radiation pressure for an absorbent surface

       P = I / c        absorbent surface

       P = F / A

       F / A = I / c

       F = I A / c

The area of ​​area of ​​a circle is

      A = π r²

We replace

     F = I π r² / c

Let's calculate

     F = 8.0 10⁻³ π (1.0 10⁻⁶)²/3 10⁸

     F = 8.375 10⁻²³ N

Density is

      ρ = m / V

      m = ρ V

      m = ρ (4/3 π r³)

      m = 4500 (4/3 π (1 10⁻⁶)³)

      m = 1,885 10⁻¹⁴ kg

Let's calculate the acceleration

     a = 8.375 10⁻²³ / 1.885 10⁻¹⁴

     a = 4.44 10⁻⁹ m/s²               absorbent surface

The correct answer is B

Would the solar panel work under a fluorescent or halogen light? explain your response being sure to relate your observations to
eduard

I think that the solar panel would work under a fluorescent or halogen light if the photons are being produced. These types of lights mimic sunlight so it would not work as good as the real thing but it could work. Just not be as powerful.

Given that no sunlight can penetrate Europa’s ice shell, what would be the type of energy that could make some form of europan l
Anna71 [15]

Answer:

life in europa is possible due to chemical energy, surface and ocean intracts with one another and give off chemical energy.

Explanation:

the ocean in europa is in contact with the underlying rocky mantle and at high temperatures, its rocks and water interact. oxidization and reduction in which molecules give off and accept electrons occur in it  and in deep ocean, when chemically reduction vent fluids interacts with oxygen containing seawater to produce energy that can support micro-organisms and animals.
