For this problem, we have to use the Planck's equation.

E = hv
where
E is the energy
h is Planck's constant equal to 6.626×10⁻³⁴ J·<span>s
v is the frequency in Hz or s</span>⁻¹<span>

Applying the equation, the answer would be:

E = (</span>6.626×10⁻³⁴ J·s)(5.49×10¹⁴ s⁻¹)
<em>E = 3.64×10⁻¹⁹ J</em>

How could we stop an asteroid that we know was going to hit Earth?<br><br><br> Pls help ASAP
myrzilka [38]

Answer:

An object with a high mass close to the Earth could be sent out into a collision course with the asteroid, knocking it off course. When the asteroid is still far from the Earth, a means of deflecting the asteroid is to directly alter its momentum by colliding a spacecraft with the asteroid.

Hope it helps!!

Neptune's Triton is being pulled closer and closer to the planet as it orbits. What will likely be a result of this gravitationa
Ksenya-84 [330]

Answer:

the planet's gravity will cause Triton to fly into Neptune

Explanation:

Gravitational force is a force of attraction between two bodies with considerable masses.

One of the mass tends to pull the other to it's center.

As the force of gravity between two bodies grow, the more massive body will be drawn to the other one.

  • The effect is that one body will eventually collide with the other.
  • Since the planet pulls very hard on its moon
  • On the long run, we can expect Triton to fly into Neptune in the foreseeable future.
