Suppose a hydrogen atom in its ground state moves 130 cm through and perpendicular to a vertical magnetic field that has a magne
tic field gradient dB/dz = 1.2 × 102 T/m. (a) What is the magnitude of the force exerted by the field gradient on the atom due to the magnetic moment of the atom's electron, which we take to be 1 Bohr magneton? (b) What is the vertical displacement of the atom in the 130 cm of travel if its speed is 2.2 × 105 m/s?

Answer:
Height of the building = 11.4 m
Explanation:
As we know that the stone is projected at an angle 46 degree with speed 8.65 m/s
so the two components of the speed is given as
vertical component of the speed is given as
now we know that the ball strike at horizontal distance of 13.7 m
so we will have
now we know that in vertical direction ball will move under uniform gravity so we can use kinematics
Height of the building = 11.4 m
Answer:
Distance will be 49.34 m
Explanation:
We have given wavelength
Diameter of the antenna d = 2.7 m
Range L = 7.8 km = 7800 m
We have to find the smallest distance hat two speedboats can be from each other and still be resolved as two separate objects D
We know that distance is given by
So distance D will be 49.34 m
