What is 4 mL?
- m (mass)
- F (force)
- v (volume)
- S (speed)
- t (time)
- D (density)
- a (acceleration)
2) An object displaces 4 mL and is 24 g. Calculate the object's density.
v = 4 mL
What is 24 g?
- m (mass)
- F (force)
- v (volume)
- S (speed)
- t (time)
- D (density)
- a (acceleration)
2) An object displaces 4 mL and is 24 g. Calculate the object's density.
v = 4 mL
m = 24 g
What is your unknown?
- m (mass)
- F (force)
- v (volume)
- S (speed)
- t (time)
- D (density)
- a (acceleration)
2) An object displaces 4 mL and is 24 g. Calculate the object's density.
v = 4 mL
m = 24 g
D = ? (your unknown)
What equation will you use?
- D = m/v
- Q = (m)(ΔT)(Cp)
- S = D/T
- a = (Δv)/(Δt)
- p = mv
- F = ma
- W = Fd
2) An object displaces 4 mL and is 24 g. Calculate the object's density.
v = 4 mL
m = 24 g
D = ? (your unknown)
Equation: D = m/v
Which of the following is correct?
- D = m + v
- D = m - v
- D = m x v
- D = m ÷ v
2) An object displaces 4 mL and is 24 g. Calculate the object's density.
v = 4 mL
m = 24 g
D = ? (your unknown)
Equation: D = m/v
Which of the following is correct?
- D = 4/24
- D = 24/4
- 24 = 4 x v
- 4 = 24 ÷ v
2) An object displaces 4 mL and is 24 g. Calculate the object's density.
v = 4 mL
