Answer:
force×distance
Explanation:
work is the ability of an object to move a distance as a result of the force being applied
Use the formula t = d/v
t = 15 km/ 37 km/h
t = 0.4054
t = 0.41 h (rounded)
Given that the linear expansion of the pipe is 12×10¯⁶ K¯¹, the pipe extends by 0.024 mm
<h3>Data obtained from the question </h3>
- Original length (L₁) = 100 mm
- Change in temperature (ΔT) = 20 K
- Coefficient of expansion (α) = 12×10¯⁶ K¯¹
- Change in length (ΔL) =?
<h3>How to determine the new diameter </h3>
α = ΔL / L₁ΔT
12×10¯⁶ = ΔL / (100 × 20)
12×10¯⁶ = ΔL / 2000
Cross multiply
ΔL = 12×10¯⁶ × 2000
ΔL = 0.024 mm
