if by arc you mean the "Period" of the pendulum then yes, it does: with each revolution the period of the pendulum (the time taken to swing back and forth once) does decrease.
A swinging pendulum has potential energy at each end of it's travel (when it stops momentarily) This energy is converted to kinetic energy as it swings down and back to potential energy as it swings up the other way.
Sound wave's transmit energy and not matter because sound travels from particle to particle transferring only energy. That is why when sound travels only the energy travels and the particles just collide with each other but stay in their positions.
gravity The force on each other is the same (action and reaction) The skier and the earth accelerate toward each other according to: acceleration = force / mass. But because the earth is so massive , (compared to the skier) its rate of acceleration is immeasurably small, as is the distance it travels. > This is only concerned with the vertical component of the skiers motion.
one degree each.
Time and distance traveled are directly proportional only if the velocity of the object in question is constant.
If a car is slowing down, the distance it travels each second will decrease. The rate at which the car covers distance will diminish as the car decelerates.
The amplitude of a pendulum is the distance between its equilibrium point and the farthest point that it reaches during each oscillation.
The time period of a pendulum will increase when taken to the top of a mountain. This is because the acceleration due to gravity decreases at higher altitudes, resulting in a longer time for the pendulum to complete each oscillation.
Decrease
Shortening the string of a pendulum decreases the distance it needs to travel, resulting in a shorter period for each swing. Since frequency is the number of swings per unit of time, shortening the pendulum causes it to move faster.
If this is a homework assignment, please consider trying to answer it yourself first, otherwise the value of the reinforcement of the lesson offered by the assignment will be lost on you.The period of a pendulum increases as it length increases because the verticle distance the bob travels is less, and thus there is less potential energy available to accelerate the bob in its arc. Also, recall that in vector mechanics the horizontal force vector due to gravity is a function of the direction the object is constrained to follow, and if the pendulum is longer, that direction is more horizontal, giving the horizontal force vector less of an effect.
For objects falling under constant acceleration (such as gravity), the distance an object travels each second is determined by the formula d = 0.5 * a * t^2, where "d" is the distance, "a" is the acceleration, and "t" is the time in seconds. This means that the distance traveled each second will increase quadratically as time passes.
The term for a measure of the distance a wave travels over time is wavelength. It is the distance between two consecutive points of a wave that are in phase with each other, such as from crest to crest or trough to trough.
Perhaps if either:The length of the pendulum is infiniteThe pendulum is in perfect zero gravity and has no momentumBut in each of those cases, does it really qualify as a pendulum?
Loudness is the perceived intensity of sound, measured in decibels (dB). Distance affects loudness by causing sound to decrease in intensity the further it travels, as sound waves disperse in all directions. The inverse square law states that the sound pressure level decreases by 6 dB for each doubling of distance from the sound source.
In that case, each second the distance travelled will be less than the second before that.
it's frequency is 2 hertz
