1. A 2.04 kg pendulum is held 0.5 m off of the ground. What is the gravitational potential energy AND total energy of the pendulum? Round
to 1 decimal place. Be sure to give me BOTH answers with units.

its a 5.5 n

glad that

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west

conservation of mass

mass before something happens = mass afterwards

part 1: which substance has a higher solubility?

a

smallest amount left undissolved atall temps in table shown most has dissolved high sol'by
