Answer:
O ice
Explanation:
Albedo refers to the proportion of the incident light that is reflected by a surface to the amount of incoming light.
Here, only <u>ice</u> will reflect even some amount of light. Pavement and dirt do not reflect at all, meanwhile, where glass reflects slightly.
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

Answer:
As we have already discussed earlier, motion is the state of change in position of an object over time. It is described in terms of displacement, distance, velocity, acceleration, time and speed. Jogging, driving a car, and even simply taking a walk are all everyday examples of motion. The relations between these quantities are known as the equations of motion.
Hey how's your day going
I hope after I answer that you understand and don't just paste my answer into your assignment!!! (<- read!!!)
Answer \|/
Ice is less dense than water.
Reason why \|/
When water freezes the molecules inside completely stop moving (They still vibrate but don't change their position much). In doing so, they spread out a touch which makes it less dense than liquid water. So ice floats
