Step-by-step explanation: The second hand on a clock rotates around the center of a clock creating a circle. This means it travels around the circle of the clock every hour. Its distance around the clock is the circumference of its circle with radius 8 cm.
This is the total distance around the clock in 1 hour. But how far does it travel in 10 minutes? 10 minutes is 1/6 of 60 minutes, a full hour. Multiply the circumference by 1/6 to find the distance in 10 minutes.
The answer is that there are more particles in 1 cubic cm. this is because within 1 cubic cm lead has 11.3g in compared to the 2.6 glass has. m/v= density. divide the masses over the volume and that will prove your answer.
