Question 10(Multiple Choice Worth 1 points) [CM.02] A student designed an experiment to show how water is recycled through the atmosphere. The steps of the experiment are shown below.
. Boil 500 mL of water in a beaker.
• Hold a hot glass plate a few inches above the beaker with a pair of tongs.
. Observe water droplets on the glass plate.
The student did not see water dripping off the glass plate as expected because the experiment had a flaw. Which of these statements best describes a
method to correct the flaw in this experiment?
Hold the glass plate closer to the beaker.
O Boil the water in a pan instead of a beaker.
Take more than 500 mL of water in the beaker,
O Use a cold glass plate instead of a hot glass plate.

i think it's c. i'm not sure but i think so.

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.
