Scientific work is currently underway to determine whether weak oscillating magnetic fields can affect human health. For example
ValentinkaMS [17]

Answer:

2.02672\times 10^{-11}\ V

Explanation:

f = Frequency = 75 Hz

B = Magnetic field = 1\times 10^{-3}\ T

d = Diameter of cell = 7.4\ \mu m

t = Time taken

\omega = Angular frequency

The expression of emf is

E=NAB\omega sin\omega t

Emf is maximum when sin\omega t=1 and N = number of turns = 1

E_m=AB\omega\\\Rightarrow E_m=\pi \left(\frac{d}{2}\right)^2 \times B \times 2\pi\times f\\\Rightarrow E_m=\pi \left(\frac{7.4\times 10^{-6}}{2}\right)^2\times 1\times 10^{-3}\times 2\pi\times 75\\\Rightarrow E_m=2.02672\times 10^{-11}\ V

The maximum emf that can be generated around the perimeter of a cell in this field is 2.02672\times 10^{-11}\ V

Toby's Trucking Company determined that on an annual basis, the distance traveled per truck is normally distributed, with a mean
Reptile [31]

Answer: 56994 miles

Explanation:

Given : Toby's Trucking Company determined that on an annual basis, the distance traveled per truck is normally distributed with

\mu=50,000\text{ miles}

Standard deviation : \sigma=12,000\text{ miles}

Let a be the distance traveled by at least 72% of the trucks.

Let X be the random variable that represents the distance traveled by a truck

Then P(x\geq a)=0.72

The critical value corresponds to p-value 0.72 :z=0.5828415

Also, z=\dfrac{x-\mu}{\sigma}

\Rightarrow\ 0.5828415=\dfrac{a-50000}{12000}\\\\\Rightarrow\ a=12000(0.5828415)+50000=56994.098\approx56994

Hence, 56994 miles will be traveled by at least (equal to and more than) 72% of the trucks .
