Answer:
1. independent- if you studied. dependent- test scores
2. independent- behavior of students. dependent-student grades
3. independent- what you eat. dependent- amount of gas
4. independent- which bait you use. dependent- how much fish you catch
5. independent-if you talk to the plants or not. dependent- growth
6. independent- whether you eat breakfast or not. dependent-student performance
7. independent- which animal you test. dependent- speed of the animals
8. independent- how much candy you eat. dependent- cavities or not
9. independent- if you eat no sugar or no carbs. dependent- how much weight you lose
10. independent- which thing you measure. dependent- the measurements
V=D/T
V=107 m / 27 s - divide distance by time
V= 4 m/s - because when we round 3.9629 in the nearest 10th we will get 4.
Hope this helps
Answer:
Explanation:
Conservation of angular momentum.
Disk I = ½MR²
Point mass I = mR² (boy)
Initial angular momentum
L₀ = Iω = ½MR²ω₀
Final angular momentum
L₁ = Iω = (½MR² + mR²)ω₁
as momentum is conserved, these are equal
(½MR² + mR²)ω₁ = ½MR²ω₀
ω₁ = ω₀(½MR²/ (½MR² + mR²))
ω₁ = ω₀(½M/ (½M + m))
ω₁ = 1.2(½(200)/ (½(200) + 50))
ω₁ = 1.2(⅔)
ω₁ = 0.8 cycles/second or 0.8(2π) = 1.6π rad/s
