Abimetallic strip consists of two metals: a on top and b at bottom. at temperature 00c this bimetallic strip was rigidly attached to the vertical wall with one end, so strip is horizontal. we know that coefficient of thermal expansion of metal a is less than coefficient of thermal expansion of metal b. temperature starts to raise. what happens to the bimetallic strip?
a. nothing happens
b. it contracts in horizontal direction
c. it bends down
d. it bends up
e. it expands in horizontal direction

Assume you measured the mass of the cart to be (500 ยฑ 1) g and the mass of the additional mass you put on the cart to be (500 ยฑ 1) g as well. since the scale you are using in the lab cannot measure objects heavier than 600g you will have to sum up individual pieces and propagate the error. so what would be the mass and the standard error of the cart and the mass
