Answer:
d = 303.33 m
Explanation:
Given that,
Acceleration of Doc Brown is 2.52 m/s²
The initial speed of Doc Brown is 0 as it was at rest.
Final speed of Doc Brown is 39.1 m/s
We need to find the distance between he and Marty. Let the distance is d. Using equation of motion as follows :
So, the distance between he and Marty is 303.33 m.
Answer:
Explanation:
We have given given the final angular velocity
And
Displacement
We have to find the angular acceleration
According to law of motion
So
In question we have tell about magnitude only so
Answer : The magnitude of the orbital angular momentum for its most energetic electron is,
Explanation :
The formula used for orbital angular momentum is:
where,
L = orbital angular momentum
l = Azimuthal quantum number
As we are given the electronic configuration of Fe is,
Its most energetic electron will be for 3d electrons.
The value of azimuthal quantum number(l) of d orbital is, 2
That means, l = 2
Now put all the given values in the above formula, we get:
Therefore, the magnitude of the orbital angular momentum for its most energetic electron is,
No sea breeze can not occur at night because while sea breezes occur during the day, land breezes occur at night. Despite the difference in times at which the land breezes and sea breezes occur, the reason for the land breeze's formation is basically the same as the sea breeze, but the role of the ocean and land is reversed.
Hope this helps ✌️
Answer:
Answer
Explanation:
The followings are the reasons for the reduction in the death toll from Tornadoes occurence in the 2000s compared to 1950s;
(a) Improvement in technology and rapid natural occurence prediction. Through the use of advanced radar systems the early detection of natural occurence e.g tornadoes, providing warning signal to the residents and tracking their possible pathways is made possible.
Fast spread of information through television channels, Radio, Social media etc., help in fast spreading of information, thereby sending early signals to people thus making them prepare for its occurence.
Improvement of protective measures, provision of housing infrastructure for the displaced. With increase in technology, the protective measures are also improving.
Quick Government and medical interventions for casualties. Conducting Tornado drills help people to practice to take cover in a specified location during tornadoes.
TV meteorologist are able to inform viewers of the approaching tornadoes and hurricanes which can be tracked from the time of its origin i.e., from a depression to a storm. Advanced radar data help in delineating the possible pathways of the hurricane.
Tornadoes on the other hand form in a thunderstorm or during a frontal activity. In thunderstorms there are vortices formed which are pre-cursors of tornadoes.. A vortice when touches the ground forms a tornado. Once a tornado is on the ground it becomes easy for radars to measure windpeeds. Hence a TV meteorologist can report the intensity of the Tornado.
