Answer:
<h3>What is the angular speed of the earth around the sun? </h3>
It takes the Earth approximately 23 hours, 56 minutes and 4.09 seconds to make one complete revolution (360 degrees). This length of time is known as a sidereal day. The Earth rotates at a moderate angular velocity of
<h3>
What is the tangential speed of the earth? </h3>
The earth rotates once every 23 hours, 56 minutes and 4.09053 seconds, called the sidereal period, and its circumference is roughly 40,075 kilometers. Thus, the surface of the earth at the equator moves at a speed of 460 meters per second--or roughly 1,000 miles per hour.
Answer:
All statement are correct.
Explanation:
1. Electric field lines are the same thing as electric field vectors, electric field are mathematically vectors quantity. These vectors point in the direction in which a positive test charge would move.
2. Electric field line drawings allow you to determine the approximate direction of the electric field at a point in space. Yes it is correct tangent drawn at any point on these lines gives the direction of electric filed at that point.
3. The number of electric field lines that start or end at a charged particle is proportional to the magnitude of charge on the particle, is a correct statement.
4.The electric field is strongest where the electric field lines are close together, again a correct statement as relative closeness of field lines indicate a stronger strength of electric field.
Hence we can say that all the statement are correct.
Go through the intersection without stopping is the appropriate action to be taken in a case where the light at an intersection is red and a police officer directs you to go through it.
<h3>What is Traffic light?</h3>
This is also referred to as stoplights and is present in the intersection of roads etc so as to help control traffic and prevent the occurrences of accidents on the road.
In cases where there is no officer, the traffic light must be obeyed but where the officer is present then his authority overrules and must be obeyed as he is in the best position to know the reason why the traffic light should be ignored in this type of scenario.
This is therefore the reason why the individual should go through the intersection without stopping.

Answer:
50%
Explanation:
Commercial aviation is responsible for 2% of global carbon emission. In the year 2009, the members of IATA (International Air Transport Association) had drawn a pledge to:
1. Halve the carbon emission due to aircraft by 2050, relative to emission of 2005
2. To make growth of industry carbon neutral by 2020
3. To cut CO₂ emission by 1.5% per year till 2020
To achieve these targets, a four pillar action plan was created.
