Cacu. H2SO.chemical properties related to the used in chemical property
Answer:
Explanation:
b = b₀ cos ω t
When t = 0 , magnetic field will be b₀ and positive or directed into the page . This is the maximum value of magnetic field. As times goes ahead , magnetic field decreases so magnetic flux decreases . The induced emf or current will be such that it will opposes this reduction of magnetic field. Hence , current in clockwise direction will be generated in the coil which will generate magnetic flux into the paper.
In this way current will be induced clockwise.

Answer:
\Delta E=1.22\times 10^{-22}J
Explanation:
The energy of electron in any state is given by 
here h is planck's constant n is state of electron L is the infinte potential well m is the mass of electron
We know that 
Potential well dimension = 
Mass of electron 
So energy required to electron to jump from ground state to 3rd state
Answer:
Explanation:
let the ladder is of mass "m" and standing at an angle with the ground
So here by horizontal force balance we will have
by vertical force balance we have
now by torque balance about contact point on ground we will have
so we will have
now from first equation we have
