We know that <span>L=Iω</span>
That is Angular momentum is equal to product of moment of inertia and angular velocity.
Now differentiating with respect to time,
<span>dL/dt=d(Iω)/dt</span>
But we know that the rate of change of angular momentum is equal to net external
torque i.e.
<span>
dL/dt=τ</span>
therefore
if no exterannal torque is acting on the body i.e. <span>
τ=0</span>then <span>d</span><span>L</span><span>/</span><span>d</span><span>t</span><span>=</span><span>0</span>
in other words
<span>d(Iω)/dt=0</span>
because <span>
dL/dt=d(Iω)/dt</span><span>
Hence angular momentum is conserved or angular momentun does not change with time if the net external force acting on the body is zero.

The steps that can be taken to reduce the risk to yourself and others are:
- use his headlamps
- traffic indicators.
<h3>What is Traffic Safety?</h3>
This refers to the behavior of road users and pedestrians alike to protect themselves from road accidents.
Hence, for a person that turns right by mistake, the next thing he should do to protect himself and others by reducing risk would be to use his headlamps and traffic indicators.

Answer:
This is an example of the paradox of authority.
Explanation:
The paradox of authority lies in that a state gets its power from being able to apply physical force and being the only entity allowed to do so, but they people will also start to question that authority if the state starts to exercise that power and applied coercion or domination. In a democracy, for example, the state still has a monopoly on violence but the people also have a right to protest against the authorities they elect and to sanction leaders for taking non-representative decisions.
