Answer:
19.62 N
Explanation:
Force acting due to gravity Fg is given by Fg=mg where m is mass in kilograms and g is acceleration due to gravity, normally a constant taken as 9.81
The mass is given in grams hence to convert into Kg we divide by 1000. Therefore, mass will be 2000/1000=2 kg
Substituting 2 kg for mass and 9.81 for acceleration due to gravity then the force due to gravity will be equivalent to
Fg=2*9.81=19.62 N
Every orbital in a sublevel is singly occupied before any orbital is doubly occupied. All of the electrons in singly occupied orbitals have the same spin
The magnetic force experienced by a charged particle moving at right angle in a magnetic field is given by:

where
q is the charge
v is the speed of the particle
B is the intensity of the magnetic field
In our problem, q=0.030 C, v=620 m/s and F=1.5 N, therefore if we re-arrange the equation and we plug these data into it, we find the intensity of the magnetic field:

Idk I think this will help :)
Explanation:
Energy is always involved in changes of state. Matter either loses or absorbs energy when it changes from one state to another. For example, when matter changes from a liquid to a solid, it loses energy. The opposite happens when matter changes from a solid to a liquid.
