Hello, im a late enrolee. Trying to catch up. Can you help me to solve these questions? Thank you!

A bimetallic strip is made of aluminum and steel (aAlsoSteal). On heating, the strip will O remain straight gut tolated O will band with aluminum inside of the band [aluminum concave side) will bend with steel inside of the band [steel concave side] When air is heated, what happens to its particles? Particles move faster and the air ampand O Particles move slower and the air expands Particles move faster and becomes more closer together Q) Particles move faster and becomes more further apart Consider the following data below. When metals A and 8 are placed in contact with each other which of the following statements is true? Metal A B Mass :) 10 30 Specific heat W/e - C 0.900 0.385 Temperature ( C) 40 O Since metal B has a larger mass, heat will flow from metal B to A. O Since motel B has a higher temperature, heat will flow from metal B to A. O Since metal B has a larger heat capacity, hant will flow from motal B 10 A. O No heat will flow in either disction The Golden Gate Bridge is said to be 127ism long at 40*C. Assuming that the bridge is made entirely of steel, what is the probable change in the length of the bridge during a cold day at -15 07 a starl - 12 x 1050-1 O dochase 0.84m inchase of 0.84m O dochase of 0.35mm O incase of 0.38mm
