Answer:
Explanation:
plate separation = 2.3 x 10⁻³ m
capacity C₁ = ε A / d
= ε A / 2.3 x 10⁻³
C₂ = ε A / 1.15 x 10⁻³
= 
a ) when charge remains constant
energy = 
q is charge and C is capacity
energy stored initially E₁= 
energy stored finally E₂ = 
=
= 
= 
= 4.19 J
b )
In this case potential diff remains constant
energy of capacitor = 1/2 C V²
energy is proportional to capacity as V is constant .
= 16.76 .
The term Milankovitch cycles most closely relate to periodic
changes in Earth’s orbit and angle of tilt relative to sun. So for this
question, the correct option is option “c”. Milankovitch affects actually deals
with the effect of the changes in the earth’s movements with the change in the
climatic conditions. Milankovitch was a Serbian geophysicist and also a great
astronomer. His studies actually helped in relating the climatic changes with
the changes in the tilt of the earth. He was the first person to mathematically
prove this situation.
Answer:
C
Explanation:
Wetlands: These are areas or placed where water covers the soil or the area or is present either at or near the surface of the soil all year or for varying periods of time during the year,it may also include the growing season.
Answer: a) close together
Explanation: The electric field lines also represent the intensity of the field, in this sense for strong electric fields it is usually draw the lines close to each other. In constrast when they are far apart the electric field is weak.
