The old rubber boot has two leaks. The top of the boot is 0.3 m higher than the leaks. What is the velocity of the water coming
out through these leaks
1 answer:
Answer:
Leak 1 = 3.43 m/s
Leak 2 = 2.42 m/s
Explanation:
Given that the top of the boot is 0.3 m higher than the leaks.
Let height H = 0.3m and the acceleration due to gravity g = 9.8 m/s^2
From the figure, the angle of the leak 1 will be approximately equal to 45 degrees. While the leak two can be at 90 degrees.
Using the third equation of motion under gravity, we can calculate the velocity of leak 1 and 2

Answer:
1.31*10⁻²⁰ J
Explanation:
- As the potential is the work per unit charge, we can find the work done by the electric field created by the charge, just multiplying the potential difference times the charge acted by the field.
- A singly ionized potassium ion has a charge equal to a positive elementary charge, e.
- So, the work done by the field can be found as follows:
- where e = 1.6*10⁻¹⁹ C and V= 82 mV
- Replacing by the values, we finally get:
- The magnitude of the work done by the electric field of the membrane is 1.31*10⁻²⁰ J
