Dante drew a diagram to show how a wire uses the magnetic field of a magnet to induce an electric current. how can dante correct the diagram?

he can move the wire upward instead of downward.

he can connect the wire to both ends of the ammeter.

he can change the wire from coiled to straight.

he can place the wire between the poles of the magnet and not move it.

I got the answer was B because to make a circuit work, you need all of the ends attached. Hope I helped!

Dante should connect the wire to both the ends of the ammeter.

Explanation: When wire is moved between the two magnets, an electric current is induced in the wire due to the magnetic field. This induced current would be detected by the ammeter.

For this, the wire at both the ends must be connected to the ammeter.

So, he should correct the diagram by connecting both the ends of the ammeter.

Mass is the amount of matter in an object. weight is the measurement of the pull of gravity on an object. say for example, you travel to the moon which has a different gravitational field compared to the gravitational field of earth. (gravitational fields: earth = 1, moon = 0.165) now when you are on the moon, the pull of gravity on you is different than on the earth. and as weight is the measurement of the pull of gravity on an object, that means yes, your weight can and will change on the moon. however, on the moon, on earth or even on jupiter, the amount of mass inside of you remains the same. meaning your physical mass remains constant. in conclusion it is possible for your weight to change as your mass remains constant.

Answer from: Quest

definition

entropy is a measure of the randomness or the extent of disorder of a chemical process.

enthalpy is a measure of the heat change of a reaction occurring at a constant pressure.

measurement units:

entropy is measured in joule per kelvin (jk⁻¹) whereas enthalpy is measured in joule per mole (jmol⁻¹)

requirements:

entropy has no requirements or limits, and its change is measured by the division between the heat change of the chemical process and the temperature.

in contrast, enthalpy can only be related to the heat change of the reaction under standard conditions.
