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

8.57 m

Explanation:

To solve the problem, we have to decompose the two vectors along the two directions first:

Vector A:

- x component: Ax = +9.66 m

- y compoment: Ay = 0 (the vector lies along the x-axis)

Vector B:

- x component:

- y component:

So now we can find the sum of the two vectors by adding the components along each axis:

And the magnitude of the sum is given by Pythagorean theorem:
