Anna71 [15]3 years ago

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.

If by floor you meant water bed then i think there isn't enough info in the question.

A car has a uniform velocity of 108km/h. How far does it travel in 30 seconds?​
natita [175]
  • Velocity=108km/h

Convert to m/s

\\ \tt\longmapsto 108\times \dfrac{5}{18}

\\ \tt\longmapsto 30m/s

  • Time=30s.

\\ \tt\longmapsto Distance=Velocity\times Time

\\ \tt\longmapsto Distance=30(30)

\\ \tt\longmapsto Distance=900m

If you increase the elasticity of a material, what happens to the speed of a mechanical wave going through it?
Sophie [7]

Answer:

At the molecular level, materials are held together by bonds, which act like springs for small displacements from the equilibrium spacing between neighboring atoms. Push the atoms close, the bond pushes back to keep them apart. Pull them apart, the bond pulls the atoms closer. For those small displacements, it acts like a spring

The speed of the wave will be related to the stiffness of of those springs - you compress the material - how quickly do all of those little springs rebound and push their neighboring atoms away, sending that wave of compression through the material.

A 15 g bullet traveling horizontally at 865 m/s passes through a tank containing 13.5 kg of water and emerges with a speed of 53
blagie [28]

Answer:

0.0613°C

Explanation:

the given parameters are m=15gm=15×10⁻³  V₁=865m/s  V₂=534m/s

the bullet moves with different kinetic energies before and after the penetration, therefore

Kinetic energy before - kinetic energy after = 1/2 × m × ( V₁² - V₂²)

                                                                         =\frac{1}{2} × 15×10⁻³ × (865² - 534²)

                                                                         = 3.47 × 10⁻³J

 this loss in energy is transferred to the water, therefore

change in temperature = \frac{Q}{m  C}

where c = heat capacity of water = 4.19 x 10^3

          m = mass of water = 13.5 kg

= {3.47 × 10⁻³} / {13.5 x  4.19 x 10^3 }

=0.0613°C
