Answer:
Corpurile care au proprietatea de a atrage corpuri usoare se află în starem
Corpurile neelectrizate sunt corpuri
Answer:
unit of current is an ampere that measures the flow of electric charge across a surface at the rate of one coulomb per second. An Ampere can be defined as the unit of electric current that is equal to the flow of one Coulomb per second

In vertical motion the arrow will be accelerating so we can use equation of motion
but first we need to find initial vertical and horizontal velocity
Horizontal velocity
cos65=x( horizontal)/20
x=8.45m/s
Thus now we can calculate time after which it strike the wall
8.45=10/t
t=1.18 s this speed in horizontal will remain constant
vertical intial velocity
sin65=y(vertical)/20
y=18.13 m/s
use the equation of motion to calculate height
s=ut+1/2 at^2
s=(18.13)(1.18)+ 1/2 (-9.8)(1.18^2)
s=21.40-6.822
s=14.58 m
but as it is already 1.80 above ground
So
The height of wall be =14.58+1.80=16.38m
ANSWER 16.38 meters
highest energy level to the ground state.
Explanation:
The transition from the highest energy level to the ground state.
An electron has a discrete amount of energy accrued to it in any energy level it belongs to.
Electrons can transition between one energy level or the other.
- When electrons change state, they either release or absorb energy.
- When an atom absorbs energy, they move from their ground to final state which is consistent with the energy of the final state.
- When electrons release energy, they move from excited state to their ground state.
- Electrons will release the greatest amount of energy when they move from the highest energy level to the ground state.
