Physics Question Two concrete spans of a 180 m long bridge are placed end to end so that no room is allowed for expansion. If the temperature increases by 20◦C, what is the height to which the spans rise when they buckle? Assume the thermal coefficient of expansion is 1.2 × 10^−5(◦C)^−1. Answer in units of m.

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.
