In normal fission reactors, the fuel used to start the nuclear fission is Uranium-235.
Generally, fuel rods enriched with uranium-235 are used to start the fission. When a nucleus of uranium-235 absorbs a neutron, it becomes unstable and then it breaks apart, producing two smaller nuclei, several neutrons and energy. The additional neutrons produced in the reaction are then absorbed by other nuclei of uranium-235, triggering other fission reactions, and so on.

What is the gauge pressure (in atm) in a 25.0°C car tire containing 3.81 mol of gas in a 31.5 L volume? (Enter your answer to at

bagirrra123 [75]

Answer:

Explanation:

Given

Temperature of gas $T=25^{\circ}C\approx 298\ K$

Volume of gas $V=31.5\ L\approx 31.5\times 10^{-3}\ m^3$

no of moles of gas $n=3.81\ mol$

Using Ideal gas Equation to find the Pressure of gas

$PV=nRT$

where P=Absolute Pressure

V=Volume

R=Universal gas constant

T=Temperature

$P\times 31.5\times 10^{-3}=3.81\times 8.314\times 298$

$P=\frac{3.81\times 8.314\times 298}{31.5\times 10^{-3}}$

$P=299.66\ kPa$

And we know Atmospheric Pressure is $101.325\ kPa$

Therefore Gauge pressure is given by

$P_{gauge}=P-P_{atm}$

$P_{gauge}=299.66-101.325$

$P=198.34\ kPa$

A 30 N rightward force is exerted on a 7 kg object. There is a 3 N force of friction acting on the object. What is the Weight of

IgorLugansk [536]

Answer:

W = 68.6 N

Explanation:

Given that,

Force acting on a right side = 30 N

Mass of the object, m = 7 kg

The force of friction acting on the car = 3 N

We need to find the weight of the object.

The weight of an object is given by :

W = mg

Substitute all the values,

W = 7 × 9.8

W = 68.6 N

So, the weight of the object is 68.6 N.
