Answer:
the direction of angular momentum = EAST
Explanation:
given
Direction of position = r = north
Direction of velocity = v = up
angular momentum = L = m(r x v)
where m is the mass, r is the radius, v is the velocity
utilizing the right hand rule, the right finger heading towards the course of position vector and curl them toward direction of velocity, at that point stretch thumb will show the bearing of the angular momentum.
then L = north x up = East
Gravitational potential energy is associated with the shape or position of an object.
1.)When an object is placed at height h above ground, gravitational potential energy associated with it is given by,
P.E = mgh
2.)In projectile motion during upward motion, kinetic energy of object is converted into potential energy.
Yes because they believe they were formed from magma solidifying.
The change in electric potential energy of the ion is equal to the charge multiplied by the voltage difference:
where the charge q of the na+ ion is equal to one positive charge, so it's equal to the proton charge:
, and Vf and Vi are the final and initial voltages.
Substituting the numbers, we find:
