A large electromagnet is used in a scrap yard to move old cars. a) Name a suitable material for the electromagnet. Explain your choice.

b) A car of mass 1800kg can be just be lifted. What is the least force that the electromagnet must use to lift the car? (1g=10 N/kg)​

another example of kinetic energy would be,

kinetic energy   >     moving energy

answer   >   letter choice (c),   a hammer falling off a table.

hope that !                                         : )

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
