Is there more than one way to get 2 objects with identical masses to balance?
yes
What are some example of activities or inventions that manipulate air resistance to slow things down or speed them up?
identical masses dropped from the same height with and without a parachute
Does mass effect the period of a pendulum?
Galileo showed that the speed of heavy objects is the same as light ones (except for light ones that are slowed by air resistance, which is not the case for simple pendulums with reasonably heavy bobs). Since the motion of a pendulum is essentially an object falling toward the center of motion and masses fall at the same rate, the swing time of the pendulum does not depend on mass. See link.
What is attractive force of matter?
The attractive force of matter is the gravitional forces between the two masses. The force of the attraction is inversely proportional to the square of the distance. You are pulling the Earth toward yous with the same proportionate attraction that the Earth is pulling you, relative to each of your own relative weight. See Cavendidh's experiment on the attraction of masses.
Is the ability of a medium to vibrate by absorbing energy at its natural frequency?
Sympathetic vibration is the name given to the phenomenon where the energy may be transferred from one vibrating system, to another similar one close by.The simplest case would be for you to pluck just one of the tynes of a tuning fork. Both tynes will vibrate in synchrony. The strings of a piano are often multiple ones, and this synchronous vibration add pleasantly the the timbre of the sound.A more impressive demonstration is made by suspending a pair of small masses from a beam, a few inches apart, using light thread. If you start one of the masses to pendulum, you'll find that the other starts to pendulum also, with a little movement at first, but becoming greater and greater. Eventually, the first pendulum will slow and stop. Then gradually increase its swing, as it recovers the momentum from the other pendulum.Resonance is the other name for the natural frequency.
Why we use two masses with identical geometries for simple pendulum?
An ideal (simple) pendulum has ONE mass, and a massless cord that sustains it.
Is there more than one way to get 2 objects with identical masses to balance?
yes
Would the masses be identical if you measure the exact measure of carbon dioxide and water entered a plant and sugars produced?
no
What 2 particles have similar masses?
Protons and neutrons have near identical mass. One will not have to account for the difference in mass in most calculations.
A scientist from this country did a experiment about gravity he droped balls of different masses from this famous tower?
italy, the leaning tower of Pisa
How does the law of conservation of mass to a burning candle?
The mass of the initial candle is identical with the sum of masses of released gases from burning and the residues remained.
What country was the man from who dropped balls of different masses from a famous tower to do an experiment about gravity?
That man would be Galileo Galilei, and he was from Italy.
A scientist from this country did an experiment about gravity. He dropped balls of different masses from a famous tower?
Galileo Galilei; leaning tower of Pisa.
What are two ancient greek theories of matter?
Dalton's Atomic theory: all elements contain tiny atoms, that's the only way an element is pure because al atoms of an element were identical and it also explains the identical masses
Which is greater 4kg or 4000g?
They're identical masses.
Would the masses be identical if you measure the exact amount of carbon dioxide and water entered a plant and sugars produced?
Only if you included the Oxygen produced as well.
What is Grazing Incidences and Grazing Emergent?
two identical metal masses are taken one is given a positive charge and the other an equal negative charge .will their mass changes?
