HEL 70PTS NOT A LIE Explain what it means when we say a substance is magnetic.
Discuss the relationship between electric and magnetic fields.
What type of metals are known as ferromagnetic metals?
Open the lab interactive and run a few trials changing the variables each time. Decide which variable you want to change in order to make a strong electromagnet, and record it here. This will be your independent variable.

Explanation:

a magnetic substance is one that is attracted by magnets electricity and magnetism are two related phenomena produced by electromagnetic force.A moving electric charge forms a magnetic field ferromagnetism is a a magnetism related to iron,cobalt, nickel or

Answer: it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.explanation:   we have equation of motion ,where s is the displacement, a is the acceleration, u is the initial velocity and t is the time taken.average velocity = displacement/ time taken.average velocity = 10.69 miles/hr = 10.69*1.6*1000/(60*60) = 4.75 m/s4.75 = s/ts = 4. 1we also have acceleration = 2.18 m/s², initial velocity = 0 m/sso it will take   4.36 seconds to reach her average velocity 10.69 miles/hour.
