What is the equation linking force, acceleration and mass?
mass = acceleration + force
force = mass ÷ acceleration
force = mass x acceleration
acceleration = force x mass^2
Boyle's Law states that pressure and volume are directly proportional.
Which of the following are scalar quantities?
Speed
Displacement
Force
Energy
Time
Velocity
Pressure = force ÷ area
Which is the best definition for density?

The amount of matter present per unit area.
How closely packed the particles of a material are.
The amount of matter present per unit volume.
What does the Gay-Lussac Law state?
Pressure and temperature in gases are directly and positively related.
Pressure and volume in gases are directly and positively related.
Pressure and temperature in gases are inversely related.
Pressure and volume in gases are negatively related.
Which electrical component does this symbol represent?
