HURRY PLEASE AND THANKS Read Made-to-Order Magnets Keep the article open throughout the assignment
Select the statement that best summarizes the central idea of the article.

A)Electromagnets are useful in many situations because they can be turned on and off.

B)Motors change mechanical energy to electrical energy

C)Electromagnets work whether or not electricity is passing through the wire.

D)Electromagnets are useful around the home but not in industry

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft

snell's law

refractve index = sin incidence / sin refraction

in order to follow the instructions and complete the statements, i need to use data from table c of your student guide. can you think of a way to let me see your student guide for a while ? i can't answer the question without the data in table c.
