Updated: 11/8/2024

Well, honey, a penny has a diameter of about 0.75 inches, so we can calculate the surface area using the formula for the area of a circle. The surface area of a penny is approximately 0.441 square inches. So, there you have it, the glamorous surface area of a humble little penny.

The surface area of a penny can be calculated by first determining the diameter of the coin, which is approximately 0.75 inches or 19.05 millimeters. Using the formula for the surface area of a circle (A = πr^2), where r is the radius (half the diameter), the surface area of a penny is approximately 0.4417 square inches or 2.844 square centimeters.

diameter of penny is 19mm

radius is 9.5mm

area= pi (3.142)(9.5mm)squared= 90.25x3.142=283.565 sq mm

What force causes a leaf to fall more slowly than a penny?

We know that air resistance (or atmospheric drag) is what causes a leaf to fall more slowly than a penny. A large leaf that weighs a much as a penny has a much greater surface area than the penny, and all this surface area means that the leaf has more drag. Though the leaf and penny will be accelerated by the same amount of force (because they have the same mass), the leaf will present all that surface area to the air, and this will set up a condition of high drag.

Why does water bubble up on a penny?

Water molecules have a high surface tension, causing them to bead up on the surface of a penny due to its hydrophobic nature. As more water is added, the surface tension is overcome, leading to the formation of bubbles on the penny as the water tries to minimize its contact area with the metal.

How surface tension behaves?

for example, if drops of water are placed on the top of a penny, the surface tension is going to hold the drops on top of the penny. when the penny can hold no more, it will all overflow. make sense?

How do you make a penny float?

One way to make a penny float is by using the surface tension of water. Carefully place the penny on the surface of water in a bowl or cup, making sure it is placed flat. The surface tension of the water will allow the penny to stay afloat.

Why does water stay on a penny?

Water stays on a penny due to its high surface tension. This property of water causes it to form droplets on non-absorbent surfaces like the smooth surface of a penny, instead of spreading out.

What keeps water on a penny?

The surface tension of water keeps it on a penny. Surface tension is the result of intermolecular forces between water molecules that create a "skin" on the water's surface, allowing small objects like a penny to float.

Does water temperature affect surface tension on a penny?

Yes, water temperature can affect surface tension on a penny. As water temperature increases, surface tension generally decreases. This means that with higher water temperature, the water is less likely to bead up and more likely to spread out on the penny, reducing the surface tension.
