four students are doing different friction experiments with a cylinder.

tristan is working with static friction,
arya is working with sliding friction,
anoush is working with rolling friction,
and keran is working with fluid friction.

***which most likely describes results from their experiments?

a. tristan and arya would exert more energy to overcome friction than anoush and keran.
b. tristan and anoush would exert more energy to overcome friction than arya and keran.
c. tristan and keran would exert less energy to overcome friction than arya and anoush.
d. tristan and arya would exert less energy to overcome friction than anoush and keran

Water molecules have a strong attraction to each other because of hydrogen bonding, allowing water to move against gravity up a plant's stem through capillary action. true false

Inside a flashbulb, oxygen surrounds a thin coil of magnesium. when the flashbulb is set off, a chemical reaction takes place in which magnesium combines with oxygen to form magnesium oxide. which of the chemical equations matches the reaction above? a. mg + o2 mgo2 + energy b. 2mg + o mg2o + energy c. 2mg + o2 2mgo + energy d. mg + o mgo + energy

Under what conditions will a gas be most likely to exhibit the ideal gas properties predicted by the ideal gas law? 1)high pressures and high temperature, because particles are forced closer together with higher kinetic energy, so intermolecular forces of attraction are weaker 2)high pressure and low temperature, because particles are forced closer together and moving slower, so the volume of the particles is less significant 3) low pressure and high temperature, because particles are spread farther apart and moving faster, so the intermolecular forces of attraction are weaker 4)low pressure and low temperature, because particles are spread farther apart with lower kinetic energy, so the volume of the particles is less significant
