The answer is B. Nutrients.
Answer:
(C) 16
Explanation:
Given:
The amplitude of first wave (s₁) = 20 mm
The amplitude of second wave (s₂) = 5 mm
Intensity of first wave = Iₓ
Intensity of second wave = 
The intensity associated with a wave depends on the amplitude of the wave.
The intensity (I) is directly proportional to the square of the amplitude (s) of the wave and is expressed as:
Now, the intensities of the two waves are given as:
Dividing both the intensities, we get:
Therefore, the option (C) is correct.
Matter is a thing. ex: paper. notice how paper can be written on. notice how it is ...well, THERE. now notice light. the light is not atoms. it is electricity that does weird stuff to create a big enough source of energy to be a source of light. sorta like fireflies
Answer:
A= Q/4 B=0 C=Q/4
Explanation:
The initial condition, is as follows:
A=Q B=0 C=0
When A is brought to contact with B, as both spheres are conductors, charge distribute evenly between the two spheres, so after this, the charges on the spheres are as follows:
A= Q/2 B=Q/2 C=0
If B touches C, while C is grounded, this supplies a infinite source of sink of charge, so both spheres lose any charge.
At this stage, the charge distribution is as follows:
A = Q/2 B=0 C=0
Assuming C is not grounded, when finally touches A, the charge on A distributes evenly between A and C, so the final situation is as follows:
A = Q/4 B=0 C=Q/4
