Explanation:
just simple gearing ratios
Answer:
699.67ft
Explanation:
We are given with,
- α = 1.2×10⁻⁵ / °C
- L₀ = 700 ft
- ΔT = -10°C − 30°C = -40°C
Now, We have to find ΔL:
- ΔL = (1.2×10⁻⁵ / °C) (700 ft) (-40°C)
- ΔL = −0.336
Rounded to two significant figures, the change in length is −0.33ft.
<u>Therefore, the final length is approximately 700 ft − 0.33 ft = 699.67ft</u>.
Answer/Explanation:
The highest point of potential energy is A, when the ball rolls down the hill potential energy decreases and kinetic energy decreases, but the total energy is constant no matter what. This means the energy does not go away but instead is transferred to a different form.
A: most potential and least kinetic
B: losing potential gaining kinetic
C: losing more potential and gaining more kinetic
D: most kinetic and least potential
E: Gaining potential and losing kinetic
F: Gaining more potential and losing more kinetic
G: more potential than kinetic but not the most potential
