Answer:
Explanation:
Using the formula for refraction at curved surface
For refraction at first surface
μ₂ /v -μ₁ /u = ( μ₂ - μ₁ )/R
1.5/v -1/-45 =.5/14
v = 111 cm
For refraction at opposite surface ,
u ( object distance ) = 111 - 28 =83 cm
It will act as virtual object for surface 2 so it will be positive in sign
again using the above equation for 2 nd surface we have
1/v - 1.5/83.17 = -.5-=/-14 = 1/28
v = 18.62 cm from second face.
yes, virtual image will be formed.
Answer:
72000 miles
Explanation:
If the distance between the students is 600 miles, and this implies in a 3 degree difference in the sun position, that means this 600 miles is related to 3 degrees of the circunference of the planet.
So, to find the whole circunference of the planet, that is, 360 degrees, we just need to use a rule of three:
3 degrees -> 600 miles
360 degrees -> x miles
3x = 600 * 360
x = 600 * 360 / 3 = 72000 miles
Answer:
D) fused hands, no range of motion.
Explanation:
As we've seen in blind people, blindness is adapted to and other skills are highly developed to accommodate. B would be awkward, but not deadly. C would be fine mostly, since we are still able to see. However, D, with no range of motion, we would find it very difficult to defend ourselves and care for ourselves.
