Gizmo Warm-up Usually when you experiment with circuits, you use a battery or another
energy source to create a current. But is it possible to generate a
current without a battery? You can find out with the Electromagnetic
Induction Gizmo.
In the Gizmo, you can drag the wire loop around or use the controls to
move the magnet up and down. You can also rotate the wire loop.
Experiment with the Gizmo to see how many different ways you can
create a current in the wire loop and light the light bulb. Describe your
findings below (2 marks)

Adiver named jacques observes a bubble of air rising from the bottom of a lake (where the absolute pressure is 3.50 atm) to the surface (where the pressure is 1.00 atm). the temperature at the bottom is 4.00 ∘c, and the temperature at the surface is 23.0 ∘c.what is the ratio of the volume of the bubble as it reaches the surface (vs) to its volume at the bottom (vb)? if jaques were to hold his breath the air in his lungs would be kept at a constant temperature. would it be safe for jacques to hold his breath while ascending from the bottom of the lake to the surface?
