For a radio station broadcasts at a frequency of 83.8 MHz with a power of 16.5 kW, the number of photons is mathematically given as
P=6.92*10^{29}photon/sec
<h3>What is the number of photons does the antenna of the station emit in each second?</h3>
Generally, the equation for the energy is mathematically given as
E=hf
Therefore
E=6.63*10^{34}*83*10^6
E=5.561*10^26J
In conclusion, the number of photons
P=dN/dt
P=38500/5.561*10^{26}
P=6.92*10^{29}photon/sec

A. Starts slowly and then accelerates.
Answer: rusting iron!
explanation: because it changes the metal into rust using oxygen and water
Answer:
23895.05 Pa
Explanation:
V = 0.03 m³
mass, m = 4 g
Temperature, T = 388 K
Let P be the pressure.
number of moles, n = 4 / 18 = 0.22
Use ideal gas equation
PV = n RT
P x 0.03 = 0.22 x 8.314 x 388
P = 23895.05 Pa
Thus, the pressure is 23895.05 Pa.
Answer:
The person will travel 24 meters.
Explanation:
Distance = Rate * TIme
Distance = d = ?
Rate = r = 6 m/s
Time = t = 4 seconds
d = r*t = (6 m/s)*(4 seconds)
d = 24 m
**Note that the units (m/s) and (s/1) cancel to leave the answer in meters, the desired unit**
