Answer:
250cm^3
Step-by-step explanation:
One mililiter of water has a volume of 1 cubic centimeter, or 1cm^3. Since there are 250 mililiters, there are 250 cubic centimeters of water.
Answer:
t_a = 7 s
t_w = 5 s
Step-by-step explanation:
Given:
- The average speed in air v_a = 16 m/s
- The average speed in water v_w = 3 m/s
- The total distance D = 127 m
- The total time T = 12 s
Find:
How long did the stone fall in air and how long did it fall in the water?
Solution:
- Lets time taken by stone to drop through air as t_a = t_a.
- The time taken in water would be t_w = (12 - t_a)
- The total distance covered can be calculated as:
D = v_a*t_a+ v_w*(12 - t_a)
127 = 16*t_a + 3*(12 - t_a)
Simplify and solve for t:
91 = 16*t_a - 3t_a
13*t_a = 91
t_a = 7 s
t_w = 5 s
Try this solution:
The correct answer is 'a' only, where x= -4;-1 and y= -6;-21
59.6 is the answer rounded to the nearest tenth
