Energy in a machine can be something technical like a wire or something went wrong with the system
Explanation:
Given:
v₀ = 0 m/s
a = 2.50 m/s²
t = 4 s
Find: v
v = at + v₀
v = (2.50 m/s²) (4 s) + 0 m/s
v = 10 m/s
Answer:
If conditions are just right, you can see Polaris from just south of the equator. Although Polaris is also known as the North Star, it doesn't lie precisely above Earth's North Pole. If it did, Polaris would have a declination of exactly 90 degree.
Explanation:
You need to use snell’s law in this problem. N1sin (theta) = n2sim (theta)
N1 = index of oil
N2 = index of glass
If you already have the numbers, include it in this
equation:
N1.sin (90deg) = N2.sin (critical angle) (note sine (90deg)
= 1)
