What is the difference between a radiological weapon and a nuclear weapon?
AVprozaik [17]

What is the difference between the nuclear material in a bomb, versus a reactor? A nuclear reactor works by using the energy that is released when the nucleus of a heavy atom splits. That process is called fission. In reactors, fission occurs when uranium atoms are hit by slow-moving neutrons.

Would an increase in pressure favor the formation of ozone or of oxygen?
max2010maxim [7]
<h3><u>Answer;</u></h3>

<u>An increase in pressure favors the formation of ozone </u>

<h3><u>Explanation;</u></h3>
  • Ozone, O3, decomposes to molecular oxygen in the stratosphere according to the reaction

2O3(g) ⇆ 3O2 (g).

  • There are more moles of product gas than moles of reactant gas. An increase in total pressure increases the partial pressure of each gas, shifting the equilibrium towards the reactants.
  • Therefore; an increase in pressure favors backward reactions towards the formation of ozone.

A footballer kicks a ball at angle teta to horizontal with some initial velocity a) what are the two types of independent motion
Nezavi [6.7K]

a) The motion along the vertical direction and the motion along the horizontal direction.

b) The object remains in the air for a time period of 2usin(θ)/g.

Any object that is thrown in the air when gravity is acting on it is called a projectile. The motion of this projectile is called projectile motion.

When the projectile is thrown in the air at some angle θ, then there are two independent motions taking place at the same time. First is the component of motion along the vertical direction along which gravity acts. Second is the component of motion along the horizontal direction along which the object moves with a constant velocity. No force acts along the horizontal direction. The horizontal motion does not affect the vertical motion and the converse is also true. So these are independent of each other.

The time of flight is the time during which a projectile remains in the air. This time of flight is calculated using the formula,

T=2usin(θ)/g

where T is the time of flight, u is the initial velocity and g is the acceleration due to gravity.

Hence, the object remains in the air for a time period of 2usin(θ)/g.
