Energy stored= 1/2 * capacitance * voltage^2
= 1/2 * 10*10^-10* (1.7*1000)^2
= 1.7*1.7/2000 J
Answer:
Explanation:
Given:
- mass of the first ball,
- initial velocity of the first ball,
- mass of the second ball,
- initial velocity of the second ball,
- Final velocity of the first ball,
<u>Using the law of conservation of linear momentum:</u>
where: final velocity of the second ball
<u /><u />
<u>Now the kinetic energy lost in the collision:</u>
Δ KE = (Sum of initial individual kinetic energy) - (Sum of individual final kinetic energy)
Did you mean acceleration? “Average acceleration is the final velocity minus the initial velocity per time taken”
Answer:
The peak current carried by the axon is 5.85 x 10⁻⁸ A
Explanation:
Given;
distance of the field from the axon, r = 1.3 mm
peak magnetic field strength, B = 9 x 10⁻¹² T
To determine the peak current carried by the axon, apply the following equation;
where;
B is the peak magnetic field
r is the distance of the magnetic field from axon
μ is permeability of free space = 4π x 10⁻⁷
I is the peak current
Re-arrange the equation and solve for "I"
Therefore, the peak current carried by the axon is 5.85 x 10⁻⁸ A
