Take pushing a box, for example-- You push your hardest then give out, still trying to push the box. You are doing less work than what you have started with!

Answer:
16.3 m/s
Explanation:
We are given that
Mass of golf ball=m=0.045 kg
We have to find the speed right after the hit.
Force,F=70 N
Change in momentum=Area of trapezium
Area of trapezium,A=
Using the formula
Initial velocity of golf ball=u=0
The correct answer of this question is : A) Radio waves have longer wavelengths, lower frequency, and lower energy than ultraviolet waves and x-rays.
EXPLANATION :
Before going to answer this question, first we have to know the electromagnetic spectrum.
Electromagnetic spectrum is the arrangement of electromagnetic waves in the ascending order of frequency or descending order of wavelength.
When the waves are arranged in the ascending order of their frequency, then perfect order is given below as such -
Radio wave < Micro wave < Infrared wave < Visible light < U.V ray< X-ray < Gamma ray .
Hence, we see that radio wave has the least frequency, and gamma ray has the most frequency.
We know that wavelength and frequency are inversely are inversely proportional to each other. Hence, radio wave has more wavelength and less frequency.
The wave having more frequency is more energetic. Hence, gamma is more energetic and radio wave is less energetic .
