A red blood cell contains 4.8 107 free electrons. What is the total charge of these electrons in the red blood cell?
tatuchka [14]

Answer:

Charge, q=7.68\times 10^{-12}\ C

Explanation:

It is given that,

The number of electron in a RBCs, n=4.8\times 10^7

We need to find the total charge of these electrons in the red blood cell. Let it is q. Using the quantization of charge as follows :

q = ne

e is the change on electron

q=4.8\times 10^7\times 1.6\times 10^{-19}\\\\q=7.68\times 10^{-12}\ C

So, the net charge is 7.68\times 10^{-12}\ C.

If a car accelerates from a speed of 10 m/s at an acceleration of 2 m/s2 for 3s.
Flauer [41]

Answer:

\boxed{\sf Final \ speed \ of \ the \ car = 16 \ m/s}

Given:

Initial speed (u) = 10 m/s

Acceleration (a) = 2 m/s²

Time taken (t) = 3s

To Find:

Final speed (v) of the car

Explanation:

From equation of motion we have:

\boxed{ \bold{v = u + at}}

By substituting value of u, a & t in the equation we get:

\sf \implies v = 10  + 2\times 3 \\  \\ \sf \implies v = 10 + 6 \\  \\ \sf \implies v = 16 \: m {s}^{ - 1}

\therefore

Final speed (v) of the car = 16 m/s
