Hydrogen atoms are placed in an external magnetic field. The protons can make transitions between states in which the nuclear sp
in component is parallel and antiparallel to the field by absorbing or emitting energy.What magnetic-field magnitude is required for this transition to be induced by photons with frequency 23.1 MHz?

Answer:
Relation between initial speed of bullet and height h is given as
Explanation:
As we know that system of block and bullet swings up to height h after collision
So we have
so we have
so speed of the block + bullet just after the impact is given by above equation
Now we also know that there is no force on the system of bullet + block in the direction of motion
So we can use momentum conservation
now we have
