Understanding Density and Motion

What is the mass of an object with a density of 5 g/cm³ and a volume of 10 cm³?

• 70 g

• 100 g

• 50 g

• 30 g

If a car travels at a speed of 60 km/h for 2 hours, how far does it travel?

• 120 km

• 90 km

• 100 km

• 150 km

Explain the difference between distance and displacement.

• Distance is a vector quantity while displacement is a scalar quantity.

• Distance is always greater than displacement.

• Displacement measures the total path traveled regardless of direction.

• Distance is a scalar quantity representing total movement, whereas displacement is a vector quantity representing the change in position.

• 12 g

• 8 g

• 5 g
