Based on the table, deduce the formula for calculating density using fundamental quantities.
Based on the table, deduce the formula for calculating density using fundamental quantities.
Density (ρ) = Mass (kg) / Volume (m³)
What are the symbols representing 'Speed' and 'Force' in the provided table?
What are the symbols representing 'Speed' and 'Force' in the provided table?
While no symbols are explicitly provided in the table, we can infer that 'Speed' is typically represented by 'v' and 'Force' by 'F'.
Using the provided fundamental quantities, identify the derived quantities that involve a combination of mass and time.
