Miniature circuit breakers is called the developed form of fuse because MCBs are more sensitive to current than fuses. They immediately detect any abnormality and switch off the electrical circuit automatically. This prevents any permanent damage to electrical appliances and human beings

The differential distribution of ions across the cell membrane is due to the:
DIA [1.3K]

The differential distribution of ions across the cell membrane is due to the "resting membrane potential".

<u>Option: C</u>

<u>Explanation:</u>

The unequal allocation of charged particles like ions between the internal and external portion of cell, and by the varying membrane permeability to various ion forms, understood as resting membrane potential.

Within a sleeping brain, Na+ and K+ ions exhibit concentration gradients throughout the membrane, which push their gradients down through channels, resulting in a differentiation of the charges that generates the resting potential. With K+ than Na+ ions, the membrane is even more permeable, so the resting potential is similar to potassium ion's equilibrium potential.

WILL MARK BRAINLIEST! The driver of a pickup truck going 120 km/h applies the brakes, giving the truck a uniform deceleration of
Rudik [331]
First put the speed in m/s.  120km/h = 33.33m/s.  Now the position function is the integral of velocity, and velocity is in turn the integral of acceleration.  The velocity is:
v= \int\limits^{} _ {} {-5} \, dt =-5t+33
Now we integrate this expression to get the position. The constant of integration will be the distance the truck travels.
s= \int\limits^{} {-5t+33} \, dx =- \frac{5}{2}t^2+33.33t-35=0
Here we set the distance, 35m as negative because I assumed the stopping point of the truck is the origin.  Putting t=0 shows it starts at -35m. 
Now solve the following equation for the time, t using the quadratic equation:
s=- \frac{5}{2}t^2+33.33t-35=0
and choose the  value t=1.149s
