Answer:

A. Using artificial fertilizers instead of composting

Explanation:

Composting is actually more better than fertilizers usually, as it takes natural waste and with help of nature, returning the nutrients into soil once again. However, Artificial fertilizers usually uses chemicals to ensure that weed does not grow, and may contain other "unnatural" ingredients to ensure that only the crop grows on the field. Because of the usage of non-natural ingredients, any run-off can prove to be detrimental to any animals that eat any of the run-off infected material, or drink the polluted water.

Explanation: Using artificial fertilizers instead of composting is one of the main causes of water pollution. When it rains the artificial fertiliser will run into lakes, ponds, or any other body of water. The water will then be polluted with chemicals. Composting will not do this. There are no chemicals in compost.

natta225 [31]

The EMT must assume that any unwitnessed water-related incident is accompanied by potential spinal damage.

<h3>What is spinal damage?</h3>
  • Nerves or the spinal cord in any way damaged at the end of the spinal canal.
  • A rapid strike or cut to the spine can cause a traumatic spinal cord damage.
  • Below the damage site, a spinal cord injury frequently results in a lifelong loss of strength, feeling, and function.
  • A lot of people with spinal cord injuries may lead productive, independent lives with the help of rehabilitation and assistive technology.
  • Symptom-reducing medications and spinal stabilisation surgery are used as treatments.
  • Herniated discs are among the common injuries and diseases of the spine. Stenosis of the lower back and Scoliosis are others.
  • After taking part in a rehabilitation programme, over 80% of people with incomplete spinal cord injury (SCI) can walk again.

trasher [3.6K]

Answer:

\frac{F}{W} = 9.37 \times 10^{-4}

Explanation:

Radius of the pollen is given as

r = 12.0 \mu m

Volume of the pollen is given as

V = \frac{4}{3}\pi r^3

V = \frac{4}{3}\pi (12\mu m)^3

V = 7.24 \times 10^{-15} m^3

mass of the pollen is given as

m = \rho V

m = 7.24 \times 10^{-12}

so weight of the pollen is given as

W = mg

W = (7.24 \times 10^{-12})(9.81)

W = 7.1 \times 10^{-11}

Now electric force on the pollen is given

F = qE

F = (-0.700\times 10^{-15})(95)

F = 6.65 \times 10^{-14} N

now ratio of electric force and weight is given as

\frac{F}{W} = \frac{6.65 \times 10^{-14}}{7.1 \times 10^{-11}}

\frac{F}{W} = 9.37 \times 10^{-4}
