Does a spherical bubble of air in a volume of water act to converge or to diverge light passing through it?
viktelen [127]

Answer:

diverge light

Explanation:

The refractive index of water is greater than that of air which means that water is more denser than air and also air is optically rarer than water.

Thus,

When the beam of the light is incident from the air to the bubble which contains air, the light bends away from the normal and then the light travels from air to water and bend towards the normal. Thus, the light is first bend away from the normal and then towards the normal which means that the bubble has diverging nature. The light will likely to diverge.

mechanical equivalent of heat Do the data for the second part of the experiment support or refute the second hypothesis
Ksivusya [100]
  • The data for the first part of the experiment support the first hypothesis.
  • As the force applied to the cart increased, the acceleration of the cart increased.
  • Since the increase in the applied force caused the increase in the cart's acceleration, force and acceleration are directly proportional to each other, which is in accordance with Newton's second law.

When we state something about the results on the basis whether the observed data supports the original hypothesis, we say that we are concluding the results.

What is the relationship between force and acceleration based on Newton's 2nd law?

Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.

3 m/s
zloy xaker [14]

Answer:

0.75Hz

Explanation:

Given parameters:

Speed of the wave = 3m/s

Wavelength  = 4m

Unknown:

Frequency of the wave  = ?

Solution:

The speed of a wave is given by the expression below:

     Speed  = frequency x wavelength

  Frequency  = \frac{Speed }{Wavelength}   = \frac{3}{4}    = 0.75Hz

The moon doesn't fall to earth because of it's friction?​
TiliK225 [7]

Answer:

The Moon does not fall towards Earth right now because Earth rotates itself. The energy from the Earth's own rotation around its axis is gradually tranferred into energy of the Moon's orbital motion. That's why the Earth's rotating speed decreases but the distance to the Moon increases.
