In nuclear fission, a nucleus splits roughly in half. (a) What is the potential 2.00 × 10−14 m from a fragment that has 46 proto

Valentin [98]

Answer:

electric potential is 3.31 × $10^{6}$ V

potential energy is 152 MeV

Explanation:

given data

fragment charge Q = 46 protons = 46 × 1.6 × $10^{-19}$ C

to find out

electric potential and potential energy

solution

we know here distance from fragment d = 2 × $10^{-14}$ m

and constant for electric force k that is 9 × $10^{9}$ N-m²/C²

so that we can find electric potential = kQ/d

electric potential = 9 × $10^{9}[/tex ×46 × 1.6 × [tex]10^{-19}$ / ( 2 × $10^{-14}$ )

electric potential = 3.31 × $10^{6}$ V

and

we know relation between electric potential and potential

that is V = U/q

so U will be = qV

now put all value

we get potential energy U

potential energy = 46 × 3.31 × $10^{6}$

potential energy = 1.52 × $10^{8}$ eV

so potential energy = 152 MeV

If there is a current of 15A in a circuit for 5 minutes, what quantity of electric charge flow through the circuit?

poizon [28]

charge = current * time

q = 15 * 300 [5 min = 300 sec ]

q = 4500 C

Work done(as a measure of energy)=force x distance. Use this equation to show that the SI base units of energy are kg m^2 s^-2

Arturiano [62]

Force [kgms^-2] = mass [kg] x acceleration [ms^-2]
Work = force x distance
Work = [kgms^-2] x [m]
Work = [kgm^2s^-2]

15 POINTS! What is the function of the nervous system? What is the basic unit of the nervous system?

vlada-n [284]

The nervous system is a complex collection of nerves and specialized cells known as neurons that transmit signals between different parts of the body.

The somatic system consists of nerves that connect the brain and spinal cord with muscles and sensory receptors in the skin.

The basic unit of the nervous system is the "nerve cell," called "neuron
