During the inflow part of a cycle in the neurons approximately 5.6 × 10∧11 Na ions per meter, each with a charge of +e enter the axon.
Therefore, ions will be (5.6 ×10∧11) × (1.2/100)
= 6.72 × 10 ∧8 Na ions
Charge of an electron is 1.6 × 10∧-19 Coulombs
Thus; 6.72 ×10∧ 8 ×1.6 ×10∧-19 = 1.0752 ×10∧-10 coulombs
True. I think.................
I think fuse with 13 A... because it can withstand overloading...
Answer:
shrinks with all the fringes getting narrower
Explanation:
As the light passes through the slit, the diffraction pattern shrinks, as the waves have more opening to penetrate, and the fringes becomes more narrow as a result of that, The opposite happens as the conditions are reversed.
Answer: q=5.70 x 10^13 C
Explanation:
gravitational attraction = electrostatic repulsion GMm/d^2 = kQ^2/d^2 as you can see the d^2 cancel out. that is why lunar distance is irrelevant. G is the universal gravitational constant = 6.67 x 10^-11 m^3 / kgs^2 M is earth's mass = 5.972 × 10^24 kg m is moon's mass = 7.342×10^22 kg Q is charge on earth and moon. k is coulomb's constant = 9 x10^9 N m^2 /C^2 On solving equation for Q. Q = sqrt (GMm/k) = sqrt ( 6.67 x 10^-11 x 5.972 x 10^24 * 7.342×10^22 / 9 x10^9) = 5.70 x 10^13 C
