Mason is making a model of a front in science class. He fills clear jar halfway with olive oil. He then slowly pours very cold water that has been colored blue into the jar. The cold water sinks to the bottom of the jar and forces the olive oil upwards. Which of the following statements correctly describes an aspect of Mason’s model?

when a device is used in a circuit in which the voltage is 81 v, the current flowing through the device is 3 a. what is the resistance of the device?

a. 27 ω

b. 40.5 a

c. 243 ω

d. 243 a

the correct answer is a. 27

no. bullets are macro objects. wave nature is for light waves, extremely tiny particles. if a light particle was the size of your finger, the bullet would be the size of the universe. so basically, that huge difference in size makes the wave nature of matter insignificant.
