You are trying to teach your five-year-old brother about black holes at the dinner table and describe the event horizon like the edge of a plate and the singularity as a
grain of rice in the middle of the plate. How could you improve this analogy to be
more accurate to the nature of the event horizon and/or singularity?
Change your description of the singularity from a grain of rice to a speck of
pepper.
Make sure you mention that the "plate" is square-shaped (with four sides) to
account for all four dimensions in space time.
Remind your brother that this plate/rice analogy only works for stellar-massive
black holes.
Drape a paper towel over the plate to represent the quasar.

Iam guessing it’s a metallic because it is powdery and so belongs to group 2it is also light. so i would guess it’s graphite.if available, additional information would be very for-example its color. if black it would be division e. also try to mark it on a paper.

Grey cast iron plz mark me brainliest

Ibelieve it is d but i may be wrong

Iwould suggest the myers-briggs type indicator because the railroad unions are looking for which are focused introverts. the mbti was designed to provide a lot of information about what a person likes and what their personality based on the four-dimension scale. also for an employer it has been extremely to predict how an employee would act in a professional setting. this is what the railroad unions are looking for. they want the railroad workers to be focused and skillful to ensure the safety of everyone around them. but the other assessments don't match the criteria for the unions. like the measure disorder, emotions and self-esteem while the rorschach and tat tests are both projective tests that mainly measure someone’s personality. also, because this job is not easy, it is vital to make sure the employers are hiring the right people for the job.
