De c oefficient or linear expansion and coefficient of cubical expansion. derive the relation between them
(2) explicio experiment that determines the coefficient of linear expansion of a metal rod.
1. a body of innih temperature 0,"c is heated to final temperature 0°c derive an expression for the final lengs for the body of line
expensive
numerical problems:
a thermometer has wrong calibration it reads the melting point of ice. 12°c it reads 72°c m place of 60.
c an be temp s
of boiling point of water on this scale.
2. at what temperature do celsius and fahrenheit scales coincide? find
3 a clock which has a brass pendulurn beats seconds correctly when the temperature of the room is how many second wait
or lose per day when the temperature of the room talls to 10°c (lincar expansivity of brass 0.190

Edward tolman explained the results of his study by theorizing that the rats were learning about the maze during every trial but they a. were agitated because other groups were getting reinforcement b. could not remember how to demonstrate it without reinforcement c. were not motivated to demonstrate it without reinforcement d. seemed to be too lazy to actually work without reinforcement

1134567 a jet with mass m = 1.1 ă— 105 kg jet accelerates down the runway for takeoff at 2 m/s2. 1) what is the net horizontal force on the airplane as it accelerates for takeoff? 2.2*10^5 n your submissions: 2.2*10^5 computed value: 220000submitted: saturday, january 26 at 2: 41 pm feedback: correct! 2) what is the net vertical force on the airplane as it accelerates for takeoff? 0 n your submissions: 0 computed value: 0submitted: saturday, january 26 at 2: 41 pm feedback: correct! 3) once off the ground, the plane climbs upward for 20 seconds. during this time, the vertical speed increases from zero to 21 m/s, while the horizontal speed increases from 80 m/s to 95 m/s. what is the net horizontal force on the airplane as it climbs upward? n 4) what is the net vertical force on the airplane as it climbs upward? n 5) after reaching cruising altitude, the plane levels off, keeping the horizontal speed constant, but smoothly reducing the vertical speed to zero, in 13 seconds. what is the net horizontal force on the airplane as it levels off? n 6) what is the net vertical force on the airplane as it levels off?

The experiment was repeated many years later but the gases were mixed in a different type of container. a white solid was obtained which was xenon fluoride. predict whether you think 1) krypton and 2) radon will react with fluorine. explain reasons for your predictions
