O Magnetic field lines originate in north pole particles and end in south pole particles O Magnetic field lines form loops with no starting or ending point O Magnetic field lines will cause a force on a compass needle placed in the field The magnetic field is strongest where field lines are drawn closest together Question 5 20 What property can scientists measure if they can analyze the different frequencies of radiation emitted by an object? O the temperature of the object the mass of the object total amount of charge contained in the object O the amount of internal energy in the object No new data to save. Last checked at 8:56am Submit

Answer 1

Question 4 :-

Option A (magnetic field lines originates in north pole parties and end in South pole parties)

It is a wrong statement for magnetic field because it originated from south pole parties and end in north pole parties.

Question 5:-

Option D (the amount of the internal energy in the object ) is correct answer.

Because in the emission of different frequencies, the frequency of light emitted is a function of energy of the transition.
