I don’t know just needed points im sorry
The correct answer is C. microwaves, infrared, visible, gamma rays
Electromagnetic waves arranged in order of frequencies and wavelengths form the electromagnetic spectrum. In the order of decreasing frequency we obtain the following sequence.
Gamma ray>x-ray>ultraviolet >visible light>infrared light>microwaves>radio waves.
According to the Einsteins equation, E=hf, Energy is directly proportional to frequency. the higher the frequency the higher the energy of the photon and vice-versa.
Answer: D
All the particles must be uncharged
Explanation:
If all the particles are positively charged, then there will be force of repulsion between them which will give different directions away from each other. The same is applicable if they are all negatively charged.
If the particles are positively and negatively charged, their will be force of attraction between them which will give different directions towards each other.
For all to be experiencing forces in the same direction, We can conclude that
All the particles must be uncharged.
Complete Question
The complete question is is shown on the first uploaded
Answer:
The elastic potential energy at point B is 
The kinetic energy at point D is 
Explanation:
Looking at the given point we can observe that mechanically energy(i.e potential and kinetic energy ) is conserved and it value is 
So at point B
KE at point B is 50J
So 
Now at point D
at point D is 25J
So
