Yes. Water is a lot more dense than air, and it won't let the pendulum swing without resisting it. Both air and water are fluids, but water presents a horendous amount of drag to an object moving in it. It won't shear and "get out of the way" of the pendulum anywhere nearly as easily as air will.
The speed of a pendulum depends on its length and the gravitational pull. Taller pendulums swing slower than shorter ones, as the longer distance allows more time to complete each cycle. Additionally, heavier pendulums may swing faster due to their greater inertia.
The pendulum with a shorter length will swing faster than the one with a longer length, as the period of a pendulum is directly proportional to the square root of its length. So, if both pendulums have the same weight but different lengths, the one with the shorter length will swing faster.
The period of a simple pendulum, with very short swings, is approximated byT = 2 pi (L/G)(0.5)More complex pendulums, or pendulums with greater than insignificant swing, have more complex equations, usually to correct for circular error.
Salt water is slower.
The time of swing of a pendulum is T = 2π √ (l/g) where l is the length of the pendulum. As T ∝√l (Time is directly proportional to the square root of l) then, the longer the pendulum, the greater is the period. Therefore longer pendulums have longer periods than shorter pendulums.
Yes, light travels slower in water than in air.
salt water evaporates slower than regular water because the salt makes it harder to boil and evaporate
no
water warms up slower than land. It also loses heat slower.
Yes, light moves slower through water than through air because water has a higher refractive index than air. This causes light to bend more when it enters water, resulting in a slower speed.
The glucose molecule is much larger than the water molecule.
Salt water freezes slower than sugar because salt water has more molecules than sugar...so it drops the temp and the process of freezing
