Formula: v=d/t 60 minutes = 1 hour
A student valked 1.5 km in 25 minutes and then, realizing he was late, ran the remaining 0.5 km in 5
minutes Calculate his average speed on the way to school. (convert minutes to hours)

Because light travels in a straight line and casts a shadow, isaac newton hypothesized that light is

At very high pressures, gases become and will eventually a) more dense; become hotter b) more dense; change to a liquid or solid c) less dense; combust d) less dense; turn into a liquid

Amass attached to a spring is displaced from its equilibrium position by 5cm and released. the system then oscillates in simple harmonic motion with a period of 1s. if that same mass–spring system is displaced from equilibrium by 10cm instead, what will its period be in this case? a mass attached to a spring is displaced from its equilibrium position by and released. the system then oscillates in simple harmonic motion with a period of . if that same mass–spring system is displaced from equilibrium by instead, what will its period be in this case? a) 0.5sb) 2sc) 1sd) 1.4s
