Answer:
21560 J
Explanation:
Work = mg*h = 1100*9.8*2 = 21560 J
Answer:
Temperature on Jupiter and Saturn are too high for methane to condense.
Explanation:
However, methane can condense on Uranus and Neptune because they are farther from the sun and hence colder.
Answer:
a) # lap = 301.59 rad
, b) L = 90.48 m
Explanation:
a) Let's use a direct proportions rule (rule of three). If one turn of the wire covers 0.05 cm, how many turns do you need to cover 24 cm
# turns = 1 turn (24 cm / 0.5 cm)
# laps = 48 laps
Let's reduce to radians
# laps = 48 laps (2 round / 1 round)
# lap = 301.59 rad
b) Each lap gives a length equal to the length of the circle
L₀ = 2π R
L = # turns L₀
L = # turns 2π R
L = 48 2π 30
L = 9047.79 cm
L = 90.48 m
