Answer:
r = 71.8⁰
Explanation:
given,
refractive index of the glass 1 = 1.70
refractive index of glass 2 = 1.58
angle of incidence = 62°
angle of refraction =?
using Snell's law
1.7 ×sin 62 ^0 = 1.58× sin r
sin r = 0.95
r = sin⁻¹(0.95)
r = 71.8⁰
angle of refraction =r = 71.8⁰
Answer:
the simple machines in this list are the saw, hammer, screwdriver, ruler, and the pulley system.
Explanation:
SAW: place saw on wood then push and pull to shave away at the wood.
HAMMER: aim for nail and hit really hard without hitting your hand.
SCREWDRIVER: place screw bit in screw socket and twist.
RULER: place against object and look at the mesurement on the numbers.
PULLEY: attach an object on one end of the pulley rope and pull on the other end to raise the end with the attached object.
Un momento podría ser como, por ejemplo, la oveja podría llevarlo a algo como dar de beber a otra oveja entera o lo mismo con otros animales o incluso digamos que no sabe qué hacer para una tarea que se asignó pero su amigo lo hace, eso podría ser un problema. siguiente momento en el que tu amigo te puede enseñar qué hacer, con suerte, eso ayudó a que mi español no sea tan bueno, lo siento :/
1) in the opposite direction always
2) drag force is the force that acts in the opposite direction of the applied force (air resistance if a drag force for example)
3) frictions forces between the sole and the ground as the owner walks
4) chalk would glide very easily, so a creaking sound could never be produced, but also one could not write anything on the board!
5) I apologize for my lack of familiarity with the kind of sport but the probable answer is to raise the friction of their hands in order to decrease slipping and get a tighter, more firm grip
