Chapter 10, Problem 1VSC
To determine

To determine:  The time when there was maximum abundance of CO2 over past 800,000 year

  1. About 300,000 years ago
  2. About 125,000 years ago
  3. 1750
  4. Now

Expert Solution & Answer
Check Mark

Answer to Problem 1VSC

Solution: Option d

Explanation of Solution

Explanation:  The ppm concentration during the given time period includes:

  1. About 300,000 years ago- 300 ppm
  2. About 125,000 years ago- 300 ppm
  3. 1750- 320 ppm
  4. Now- 400 ppm

Thus, the highest concentration is now with the mark of 400 ppm

Conclusion: The ppm concentration is the highest during the present time.

Required information A bungee jumper leaps from a bridge and undergoes a series of oscillations. Assume g = 9.78 m/s². If a 60.0-kg jumper uses a bungee cord that has an unstretched length of 30.1 m and she jumps from a height of 45.2 m above a river, coming to rest just a few centimeters above the water surface on the first downward descent, what is the period of the oscillations? Assume the bungee cord follows Hooke's law.
Required information The leg bone (femur) breaks under a compressive force of about 6.50 × 104 N for a human and 12.3 × 104 N for a horse. The human femur has a compressive strength of 160 MPa, whereas the horse femur has a compressive strength of 140 MPa. What is the effective cross-sectional area of the femur in a horse? (Note: Since the center of the femur contains bone marrow, which has essentially no compressive strength, the effective cross-sectional area is about 80% of the total cross-sectional area.) cm2
