Answer:
3rd diagram
Explanation:
From the laws of reflection, we understood that the angle of incidence in equal to the angle of reflection.
For example, if a ray of light strikes a mirror at 60°, it reflected at the same angle (i.e 60°)
Considering the diagram given in the question above,
The ray of light strikes the mirror at 40°. Therefore, the light will be reflected with the same angle (i.e 40°)
Thus, the 3rd diagram gives the correct answer to the question.
Answer:
Son aquellas ondas que no necesitan un medio material para propagarse. Incluyen, entre otras, la luz visible y las ondas de radio, televisión y telefonía. Todas se propagan en el vacío a una velocidad constante, muy alta (300 0000 km/s) pero no infinita.
25 N
F = (mass)(acceleration)
F = 50 • 0.5
F = 25
Temperature is the amount of heat in degrees the object has. Heat is what is given of from thermal energy. Thermal energy is what is given off when energy is lost. Because according to the Law of Conservation of Energy: Energy can neither be created nor destroyed, but transferred to a lesser form.
The buoyant force on a submarine submerged in the ocean will equal to its weight if the submarine is at rest or the net force acting on it is zero
