Answer:

28.836 C

Explanation:

Data provided in the question:

Total number of electrons passed through the pocket calculator during a full day's operation = 1.80 × 10²⁰

Now,

We know that the charge of an electron is 1.602 × 10⁻¹⁹ C

Therefore,

The total charge moved through the calculator during the operations

= Total number of electrons passed × Charge of an electron

= (1.80 × 10²⁰) × ( 1.602 × 10⁻¹⁹ )

= 28.836 C

How do the limbs on a recurve crossbow differ from the limbs on a compound crossbow?.
olchik [2.2K]

Recurve crossbows need longer limbs and barrels than compound crossbows do to deliver a longer power stroke.

<h3>What is the difference between recurve crossbow and compound crossbow?</h3>

Recurve crossbow:

Recurve crossbows don't have cables or cams, hence their designs are less complicated than those of compound crossbows. It has bigger limbs and a bigger overall barrel to give the crossbow bolt the power it needs. The recurve crossbow is consequently heavier and bigger than the compound crossbow.

Recurve crossbows get their name from the way their limb tips curve away from the shooter to give the shot extra force. Recurve crossbows have a broader bore than compound crossbows and are a little quieter.

Compound crossbow:

Although the compound crossbow has a more intricate build, it is frequently more potent than the recurve crossbow. The limbs and barrel of the compound crossbow are smaller since the limbs do not provide the majority of its power. The additional cams and wires increase the overall weight despite the fact that it is more compact.

The compound crossbow is narrower overall, but when fired, it makes more noise than the recurve crossbow. The compound crossbow's reloading speed is also quicker due to its more compact size.
