The electric field inside a cell membrane is 8.0 MN/C. Part A What's the force on a singly charged ion in this field?

dlinn [17]

Answer:

Force on the singly charged ion will be $12.6\times 10^{-13}N$

Explanation:

We have given electric field E = 8 MN/C

So electric field in N/C will be $E=8MN/C=8\times 10^6N/C$

It is given that ion so charge on ion will be equal to $e=1.6\times 10^{-19}C$

We have to find the electric force on the ion

Electric force is equal to $F=qE$ , here q is charge and E is electric field

So force on the charge will be equal to $F=8\times 10^6\times 1.6\times 10^{-19}=12.6\times 10^{-13}N$

So force on the singly charged ion will be $12.6\times 10^{-13}N$

A motionless mass, hung on the end of a spring and pulled 5 cm downward, is a height of 1 meter above the classroom floor. Is th

maxonik [38]

Answer:

See the explanation below

Explanation:

After the mass is pulled, you have all three types of energy; potential, kinetic and elastic. Elastic as it has extension of the spring, potential energy as the mass is one meter above the ground level, and kinetic energy as the mass is in motion.

The following are the equations for calculating the different energies.

$E_{elas}=0.5*k*x^2\\where:\\k = spring constant [N/m]\\x = distance [m]\\\\E_{pot} =m*g*h\\where:\\m = mass [kg]\\g = gravity = 9.81[m/s^2]\\h = elevation [m]\\\\E_{k}=0.5*m*v^2\\where:\\m= mass [kg]\\v = velocity [m/s]$
