One result of wave refraction is that wave energy is concentrated on headlands projecting into the water. Refraction of waves involves a change in the direction of waves as they pass from one medium to another.
Explanation:
Refraction of waves comprises a change in the management of waves as they traverse from one medium to different. Refraction, or the bending of the track of the waves, is conducted by a transition toward speed and wavelength of the waves.
Answer: Science is involved in cooking, eating, breathing, driving, playing, etc. The fabric we wear, the brush and paste we use, the shampoo, the talcum powder, the oil we apply, everything is the consequence of advancement of science. Life is unimaginable without all this, as it has become a necessity.
Explanation:
What will that action cause her body to do? Why?
Which of Newton’s Laws applies to this situation?
Write a paragraph which incorporates all of the above information.
Answer:
In order to get back to the ship, the astronaut must throw the belt in the opposite direction the spaceship.
From Newton's third law of motion:
For every action, there is equal and opposite reaction.
In order to throw the belt away, astronaut would apply some force which cause same amount of force acting on her body in the opposite direction which would take her towards the spaceship.
Answer:
The mass of this object is
Explanation:
If an object floats, it means by Newton’s second law that the sum of the forces acting on it are equal to zero because it’s at rest, as you can see on the figure below, the only two forces acting on the charged particle are the weight (W) and the electric force (Fe) due the electric field (E), so Newton’s second law in this case is:
(1)
But weight is mass (m) times gravity acceleration (g) and the magnitude of the electric force is the product of the external electric field (E) and the charge of the particle (q), so using that on (1) and solving for m:
social/cultural
behavioral
biological
