a group of students performed an experiment to prove the law of conservation of energy. in the experiment, a flask containing water at room temperature was shaken vigorously for a few minutes. the table shows a partial record of the temperature of the water before and after shaking.

experimental record
temperature
before shaking 21 °c
after shaking unknown

what best predicts the unknown temperature? (3 points)

less than 21 °c because heat energy is formed from the energy used in shaking

greater than 21 °c because heat energy is formed from the energy used in shaking

less than 21 °c, because the total energy of the system after shaking is higher than before shaking

greater than 21 °c, because the total energy of the system after shaking is higher than before shaking

the table shows the potential energy and kinetic energy of a skier at two different positions on a hill.

position and energy
position (above ground) kinetic energy potential energy
100 meters 0 units 50,000 units
60 meters ? 30,000 units

what is the kinetic energy of the skier at a height of 60 meters above ground? (3 points)

20,000 units, because total energy remains unchanged

80,000 units, because total energy remains unchanged

20,000 units, because total energy of the skier decreases

80,000 units, because total energy of the skier decreases

   Greater than 21 °C because heat energy is formed from the energy used in shaking

Explanation:    I got this test and i got it right

answer; i believe the correct answer is (c) /// is a homogeneous mixture of gaseous substance nitrogen,oxygen and smaller amounts of other substancesmixtures can be either ( homogeneous or heterogeneous)plz check first good luck

that's just how they are

explanation:

you can't control another persons decisions, all you can do is ask that they respect yours. relationships are hard because you have to put the effort into making sure that another person feels seen, heard, and loved. as time goes on, it gets easier, you learn how to do these things without thinking. loving them becomes as easy as breathing, but every relationship will have fights, and sometimes it'll feel like you're drowning, but as long as you can talk it out and compromise, because that's truly what loving another person is, is compromise, then you'll be okay. movies and tv shows have glamorized and romanticized (pardon the pun) what a relationship would be like. real relationships aren't perfectly timed kisses in the rain, zero fights until one big one ends everything, 6 month anniversaries. real relationships are sleepy confused kisses when one person has to leave for work earlier than the other,   real relationships are having small disagreements, real relationships are messy and confusing, real relationships is knowing that even if you're relationship may not last forever and this may not be the person you're going to spend the rest of your life with, that you love them, and you would do anything to see them happy. so yes, relationships are difficult, but so are many other things, relationships can be amazing but also stressful, and not just romantic i'm also talking about platonic relationships (although the primary example here was romantic) sometimes is best to leave friendships behind, so remember, always do whats going to you be happy in the long run.
