Explanation:
As we know that
time = distance/speed
The time used for firs half of the trip was
(1 mi)(12 mi/hour) = 1/12 hours = 5 minutes
The last half of the trip will took 10 minutes, 1/6 hour.
Speed = distance/ time
(1 mil) = (1/6h) = 6 mil/h
so the speed for last half of the trip was = 6mph
the average speed was
(2mil)(1/4 hour) = 8 mil/hour
So the ling's average speed was 8mph.
Answer: The correct answer is- Field.
Explanation -
The modified space around a charged particle is known as electric field.
The strength of electric field at a point is calculated as the force experienced by a unit test charge present at that point.
Thus, a region of space in which a test charge experiences a force is referred to as Field.
An illustration of the impact of Frontier justice is the idea that people have the right to use fatal force against others who enter their house.
What is Frontier justice?
- Frontier justice is administrative retribution that is driven by the absence of rule and regulation or discontent with the administration of justice.
- A biased judge can also be described using this Frontier justice.
- Frontier justice is characterized by practices like lynching, vigilantism, and gunfighting.
- Like Frontier justice there is another law, named castle doctrine, also referred to as a castle law or a defense of habitation law, which is a constitutional principle that defines a person's home or any other legally occupied location as a place in which that individual has protections and immunities, allowing one, in certain situations, to use force to safeguard oneself against an attacker, free from criminal action for the consequences.

Answer:
f>1000Hz and wavelength=0.343 m
Explanation:
We are given that
Frequency of stationary siren,f=1000 Hz
Wavelength of stationary sound,
When a observer is moving towards the siren then the frequency increases.
Therefore,an observer who is moving towards the siren measure a frequency >1000 Hz.
The wavelength depends upon the speed of source.
But we are given that siren is stationary.
Therefore, source is not moving and then the wavelength remains same.
f>1000Hz and wavelength=0.343 m
