What will drop faster the penny or the feather?
The penny will drop faster than the feather due to the difference in mass and air resistance. The feather experiences more air resistance, which slows down its fall compared to the penny.
When you drop a penny what kind of motion does it have?
When you drop a penny, it undergoes free fall motion, accelerating due to gravity until it reaches terminal velocity. There is no horizontal motion involved, and the speed of the penny increases as it falls.
What was The oil drop experiment hypothesis?
The oil drop experiment was conducted by Robert Millikan in 1909 to determine the charge of an electron. The hypothesis was that the charge of individual oil droplets could be determined by observing them falling in an electric field and measuring the forces acting on them. This experiment provided an accurate determination of the charge of an electron.
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.
How do you FIND the voulme of a penny?
To find the volume of a penny, you can use the formula for the volume of a cylinder, which is V = π * r^2 * h, where r is the radius of the penny and h is the thickness. The radius of a penny is approximately 0.75 cm, and the thickness is around 0.0598 cm, so you can plug these values into the formula to calculate the volume.
