Answer:
25 km/h
Explanation:
speed=distance÷time
125÷5=speed
125÷5=25 (then add units)
I think it’s D-decreases the amount of work.
Answer:
Correct answer: P = 38,793.1 W = 38.7 kW
Explanation:
Power is calculated according to the following formula:
P = A / t
where A is the work performed and t the elapsed time
work is a measure of changing energy
A = ΔEp = m · g · h we will take that g = 10 m/s
A = 4,500 · 10 · 25 = 1,125,000 J
P = 1,125,000 / 29 = 38,793.1 W = 38.7 kW
P = 38,793.1 W = 38.7 kW

Answer:
Radio waves have longer wavelength
Explanation:
Radio wave is an electromagnetic frequency that has the ability to travel through long distance. They have frequencies shuttling been the range of 10^4 hz and a frequency of 10^12 hz
Light wave is also called visible light. This is because it is visible to the naked eye, despite it being in the electromagnetic spectrum. It's frequency is usually between 4*10^-7 hz and a frequency of 7*10^-7 hz.
As can be seen from both, the radio waves length are quite far stronger than that of the light waves.
