Answer:
2.4 secs.
Explanation:
Current (A) = Charge (coulomb)/Time(sec)
We are looking for time. So:
Time (sec) = Charge (coulomb)/Current (A)
↓
12coulombs/5.0A = 2.4 secs
The right answer for the question that is being asked and shown above is that: "The distance between the maxima stays the same; The distance between the minima stays the same.; <span>. The distance between the maxima decreases."</span>
(1 parsec) is the distance at which an object has a parallax of 1 arcsecond. The distance is about 3.26 light years.
Another way to understand it is: The distance from which the Earth's orbit appears 1 arcsecond across.
For a parallax angle of 1/2 arcsecond, the distance is <em>2 parsecs </em>(about 6.52 light years).
1 arcsecond is 1/3600 of a degree, 0.00028 degree.
Answer:
The total charge on the rod is 41.18 nC
Explanation:
Given;
length of glass rod, L = 10 cm = 0.1 m
radius of the rod, r = 4 cm = 0.04 m
Force of repulsion = 940 μN = 940 × 10⁻⁶ N
Charge on the bead = 6.5 nC = 6.5 × 10⁻⁹ C
Charge on the rod, Q = ?
From coulomb's law;
Where;
F is the force of repulsion in N
q₁ and q₂ are the charges on the bead and rod
R is the resultant distance between the two charges;
K is coulomb's constant = 8.99 x 10⁹ Nm²/C²
Therefore, the total charge on the rod is 41.18 nC
