Magnetism
Two magnets are misaligned if their magnetic field lines are . . .
Both attracting and repelling at the same time.
The density of a bag of candy must be what if the volume is 25 and the mass is 525.
Density = mass/volume
Density = 525 /25 = 21

An elf from Santa's workshop is trying to figure out the density of coal.
The mass is 400 grams.
The volume is 100 grams/cm3
What is the density of the coal?
Density= Mass/Volume
400 g / 100 g/cm3
The density of the coal is : 4 g/cm3
And the Grinch, with his grinch-feet ice-cold in the snow, Stood puzzling and puzzling: "How could it be so?” Because the Grinch was walking through the snow his feet got cold. Is there high or low friction between his feet and the snow?
Low friction
What is the velocity of a reindeer that moved at 100 m/s in 5 seconds?
Velocity = Speed/time
Velocity = 100 / 5 = 20 m/s

Will a magnet system have greater potential energy if there is a strong force when two magnets are held together and then released or if there is a really strong force when two magnets are held together and then released?
If there is a really strong force when two magnets are held together and then released.
The average Christmas present has a density of 2.15 kg/L. What would you expect the mass (in grams) to be of a present having a volume of 3650 mL?
Density = mass/volume
Mass = density x volume
Mass = (2.15) x (3.5) = 7.74 grams
