Seasons are largely due to factors surrounding the Earth's tilted axis as it revolves around the sun. A season is a period of the year that is distinguished by special climate conditions.
Answer:
When light is scattered, It reflects in many different directions, think about sunlight reflecting off the clouds.
If the separation between the openings in a laser is increased, then the distance between the interference fringes decreases
<h3>What is Interference fringe ?</h3>
Interference fringe refers to bands caused by different lights which can be found in phase or not each other.
- Distances between laser fringes are short which is due to light wavelength.
- The interference fringes can be estimated by knowing slit separation and wavelength.
In conclusion, if the separation between the openings in a laser is increased, then the distance between the interference fringe decreases

<u>Yes. The speed of a rocket can exceed the exhaust speed of the fuel.</u>
How this is explained?
- The thrust of the rocket does not depend on the relative speed of the gases or the relative speed of the rocket.
- It depends on conservation of momentum.
What is conservation of momentum?
- Conservation of momentum, general law of physics according to which the quantity called momentum that characterizes motion never changes in an isolated collection of objects; that is, the total momentum of a system remains constant.
- Momentum is equal to the mass of an object multiplied by its velocity and is equivalent to the force required to bring the object to a stop in a unit length of time.
- For any array of several objects, the total momentum is the sum of the individual momenta.
- There is a peculiarity, however, in that momentum is a vector, involving both the direction and the magnitude of motion, so that the momenta of objects going in opposite directions can cancel to yield an overall sum of zero.

Answer:
tie hair back
only burn the amount of chemicals as
directed by the lab procedure
Explanation:
The correct safety precautions for Amelia to take from the options would be <u>to tie her hair back</u> and t<u>o only burn the amount of chemicals recommended by the lab procedure.</u>
<em>With her hair left flowing freely, Amelia runs the risk of the hair catching flame while trying to burn the chemicals according to the procedure. Hence, tying her hair up into one neat bunch will limit the risk of it catching fire while working in the lab.</em>
<em>Also, burning less or more than the amount of chemicals recommended by the procedure may be dangerous or hinder Amelia from getting the right result.</em>
