What's with the bicycle? Is there a part (b)?

In a sled??😁😊

Isn't the glide ratio dependent on the horizontal velocity? The OP seems to assume that there is no initial horizontal velocity, doesn't it?

Yes, unless some context is missing. Ultrasound is just a name related to human hearing specifics. The formula without gamma was proposed by Newton and was latter corrected by Laplace by adding the gamma factor. The compression of air in a sound wave is better described as adiabatic rather than...

The integral of the current density does not have a direction in general. When we talk about a current in a wire usually we have the case of uniform current density and we call the direction of the current is the common direction of the current density, same at all points of the cross section...

No. It doesn't. The magnetic field is a vector. Does this make the magnetic flux a vector?

This is pretty much the same as the OP. Either you don't want to tell what you are actually doing, in a specific way, or you don't know yourself. In both cases it's very difficult for someone else to help. By "specific" I mean what are you measuring and why are you measuring it, as a minimum of...

It looks OK. You can also try them for some simple case. Like what happens if the two batteries in parallel are identical? Do you get the right result from your equations for this particular case?

The velocity of the circular motion is not the full velocity but just the component perpendicular to the field. And yes, the momentum have components on both directions.

If the initial flux is ## \phi_0##, the final flux will be ## - \phi_0## and the change will be ##-2 \phi_0##.

The current through the loop will change direction for the last part of the rotation. Would you add the charge going in the opposite direction to the "charge flowing through the galvanometer" or subtract it? For me, it's not clear what is expected.

Check again your conversion of the 29 m distance into cm. And make sure you get the distance image in the last step.

The same two carts will always have the same type of collision (elastic, inelastic or totally inelastic) as long as the velocities are not so high as to break them to pieces or deform them over the elastic limit (in case of an elastic collision). But these are not situations you encounter in...

No. The nature of collision (stick together or move apart) depends on the elastic properties of the objects and not on the ratio of the masses.

The text is a little confusing and possibly the author is confused too. But at this level, all that mateters is to have a fun experiment. The voltage measured across the terminals depends on the chemistry of the juice. The maximum current provided by the cell depends on the internal resistance...
