<span>They are killed mostly by heart attacks. Alternating electrical current interferes with the electrical pulses of the heart produced by the Sino-atrial node hence cause the heart to beat erratically and hence a heart attack and death to result. 7 milliamps to your heart for 3 seconds can cause it to be arrhythmic. </span>
Answer:
Correct answer: p₂ : p₁ = 1 : 3
Explanation:
A process that occurs at a constant temperature is called an isothermal process and the formula that applies to this process is:
p · V = const where p is pressure and V is volume
Given : V₂ = 3 V₁
p₁ V₁ = p₂ V₂ ⇒ p₂ / p₁ = V₁ / V₂ ⇒ p₂ / p₁ = V₁ / 3 V₁ ⇒ p₂ / p₁ = 1 / 3
p₂ : p₁ = 1 : 3
which means that when the volume is increased three times the pressure is reduced three times

Newton’s 2nd law states that Force is equal to
the product of mass (m) and acceleration (a):
F = m a --->
1
While in magnetic forces, force can also be expressed as:
F = q v B --->
2
where,
q = total charge
v = velocity = 45 cm / s = 0.45 m / s
B = the magnetic field = 85 T
First we solve for the total charge, q:
q = 3.8 × 10^-23 g (1 mol / 23 g) (6.022 × 10^23 electrons / mol) (1.602 ×
10^-19 C / electron)
q = 1.594 × 10^-19 C
We equate equations 1 and 2 then solve for acceleration a:
m a = q v B
a = q v B / m
a = [1.594 × 10^-19 C * 0.45 m / s * 85 T] / 3.8 × 10-26 kg
a = 160,437,862.2 m/s^2
Therefore the maximum acceleration of Na ions is about 160 × 10^6 m/s^2.
