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.

Simply 15 to the 18 power divide by 15 to the 3 power
andrew11 [14]
The property of exponents says that when you divide two exponents with the same base, you can keep the base and subtract the exponents. So you can do 18-3, which is 15, so it would be 15 to the 15th power

A chef is going to use a mixture of two brands of Italian dressing. The first brand contains 9% vinegar, and the second brand co
pishuonlain [190]
Let the amount of the first brand be x, and let the amount of the second brand be y.
0.09x + 0.14y = 240 * 0.13 .................(1)
x + y = 240 ..............(2)
y = 240 - x .......................(3)
Plugging the value for y from equation (3) into equation (1), we get:
0.09x+0.14(240-x)=240\times0.13 ...............(4)
Equation (4) simplifies to:
-0.05x = -2.4
giving the value for the required amount of 9% vinegar as 48 ml and the required amount of 14% vinegar as 240 - 48 = 192 ml.
