The car approaches the truck at a speed of 80-75=5km/h. To travel the 130m, it takes
Answer:
Explanation:
Average rate = gallons / minutes
If 12.5gallons in 5mins
Xgallons in 1mins
12.5/5 = 2.5gallons per minute
Ans. Littoral zone.
Littoral zone can be defined as the area of a rive, sea, or lake, which lies close to the shore. It is characterized by abundant sunlight, dissolved oxygen, nutrients, and high water motion. These characteristics make it suitable for marine life. Hence, littoral zone is enriched with various plants and animal species, and coral reefs.
For Blake:
3 boxes at a distance of 10 meters each, each box weighs 20 N
Work done by Blake = 3 * 10m * 20N
= 600 J
Power = 600 J/ 2 min
= 300 J/min
For Sandra:
4 boxes, 15 N each at a distance of 12 meters each.
Work done by Sandra = 4 * 15 N *12m
= 720 J
Power = 720 J/ 4 min
= 180 J/min
Blake does less work than Sandra.
Blake's power is more than Sandra's.
