Answer:

f = 2 Hz

Explanation:

The frequency of a wave is defined as the no. of waves passing per unit of time. Therefore, the frequency of a wave can be calculated by the following formula:

f = \frac{n}{t}

where,

f = frequency of the wave = ?

t = time passed = 1 s

n = no. of waves passing in time t = 2

Therefore,

f = \frac{2}{1\ s}

<u>f = 2 Hz</u>

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.

xeze [42]

Answer:

10

Explanation:

 Lets say that a,b,c,d,e are the five allowed energy states in order of decreasing energy. Then the number of possible different spectral lines comes from the electron dropping from a high state to a lower state. So, they will do so in following ways:

a - b

a - c

a - d

a- e

b - c

b - d

b- e

c - d

c- e

d- e

Ans- Ten different possible energy jumps giving six different colors or lines in the spectrum.
