Answer:

The energy of each photon is 6.468 \times 10^{-26} Joule.

Step-by-step explanation:

Consider the provided information.

According to the plank equation:

E=h\nu

Where E is the energy of photon, h is the plank constant and \nu is the frequency.

It is given that h= 6.6 \times10^{-34} and \nu=98MHz

98Mhz = 98\times 10^6Hz

Substitute the respective value in plank equation.

E=6.6\times 10^{-34}\times 98\times 10^6

E=6.6\times 98\times 10^{-34+6}

E=646.8 \times10^{-28}

E=6.468 \times 10^{-26}

Hence, the energy of each photon is 6.468 \times 10^{-26} Joule.

Answer:

19/4 or 4.75

Step-by-step explanation:

Week 1: 1 1/8 = 1.125

Week 2: -2 5/8 = -2.625*

Week 3: 1 3/4 = 1.75

Week 4: -1 1/2 = -1.5

Week 5: 2 1/8 = 2.125*

2 1/8 - (-2 5/8) = 2.125 - (-2.625)

19/4 or 4.75
