How do fission nuclear reactions differ from fusion nuclear reactions?
Serhud [2]
The path of the raction occurs on the basis of mass of the nuclei involved in reaction.
In case of nuclear fusion, two or more nuclei having less mass fuse(combine, join) together to form a new nuclei(heavier mass but it is relatively stable). During fusion, matter is not conserved because some of the matter is converted into energy(light). This reaction evolves a huge amount of energy and there comes Einstein's famous Energy-mass equivalence formula E=mc^2! :D. The nuclear reaction occuring in stars(including our sun ) is "fusion".

Fission occurs with heavier nuclei such as that of Uranium-235. Which splits into smaller subatomic particles like gamma, neutrons and enormous amount of energy.
Both, Fission and Fusion releases enormous amount of energy and modern nuclear weapons works on the principle of nuclear fission.

(a) If an object travels along a line with constant velocity −24 ms, then the general formula for the position of the object is_
postnew [5]

Mathematically we know that the position is the integral of the velocity as a function of time, that is, the general formula for determining the position as a function of velocity would be given by

x(t) = x_0 +\int_0^t vdt

Here

x_0 represents the initial position, and the integral, the position with respect to the speed of the object within a certain time

Replacing and considering that there is no starting position,

v(t) = -24

x (t) = -24 \int dt

x(t) = -24t+C

The membrane of the axon of a nerve cell is a thin cylindrical shell of radius r = 10-5 m, length L = 0.32 m, and thickness d =
maksim [4K]

Answer:

5.3 x 10⁻⁹ C

Explanation:

r = radius of cylindrical shell = 10⁻⁵ m

L = length = 0.32 m

A = area

Area is given as

A = 2πrL

A = 2 (3.14) (10⁻⁵) (0.32)

A = 20.096 x 10⁻⁶ m²

d = separation = 10⁻⁸ m

k_{appa} = dielectric constant = 4

Capacitance is given as

Q=\frac{k_{appa}\epsilon _{o}A}{d}                               eq-1

V = Potential difference across the membrane = 74 mV = 0.074 Volts

Q = magnitude of charge on each side

Magnitude of charge on each side is given as

Q = CV

using eq-1

Q=\frac{k_{appa} \epsilon _{o}AV}{d}

Inserting the values

Q=\frac{4 (8.85\times 10^{-12})(20.096\times 10^{-6})(0.074)}{10^{-8}}

Q = 5.3 x 10⁻⁹ C

Difference between sold and liquid​
Tcecarenko [31]

Explanation:

Solids have closely packed particles and vibrate about a fixed position, they also have a fixed volume.

liquid have close particles but which are able to move with a bit of kinetic energy, for this reason they have no fixed volume but take the volume of the container or vessel
