The concept passing a current through the loop applies the principle of the Ampere's Law. Ampere's law is commonly applied to electricity and magnetism in which it states that "<span>for any closed loop path, the sum of the length elements times the magnetic field in the direction of the length element is equal to the permeability times the electric current enclosed in the loop."</span>
The average velocity = Displacement between two points/ Time taken for that displacement
In this case An ion's position vector is initially r = 8.0 i - 4.0 j + 3.0 k, and 8.0 s later it is r = 4.0 i + 8.0 j - 6.0 k
So, displacement = 4.0 i + 8.0 j - 6.0 k - (8.0 i - 4.0 j + 3.0 k)
= -4.0 i + 12.0 j - 9.0 k
So velocity, V = (-4.0 i + 12.0 j - 9.0 k)/8
= -0.5 i + 1.5 j - 1.125 k
So average velocity during 8 seconds = -0.5 i + 1.5 j - 1.125 k
Explanation:
both are areas of land that drain to particular water bodies such as lakes
Answer:
repulsion force es R = 5,224 10⁻³ N
Explanation:
We use Newton's second law to add forces, the elective force is repulsive because the asteroids have the same type of charge and gravitational force is always attractive.
Gravitational force
Fg = G m1 m2 / r²
Fg = 6,673 10⁻¹¹ 5.7 10⁴ 5.5 10⁴/190²
Fg = 5,795 10⁻⁶ N
Electric force
Fe = k q1 q2 / r²
Fe = 8.99 10⁹ 14.0 10⁻⁶ 15.0 10⁻⁶ / 190²
Fe = 5.2296 10⁻³ N
The resulting force is
R = Fe - Fg
R = 5.2296 10⁻³ - 5.795 10⁻⁶= 5229.6 10⁻⁶ - 5,795 10⁻⁶
R = 5,224 10⁻³ N
this is a repulsive force and the asteroids move away from each other
