A disturbance moving away from its starting point is referred to as a wave. This wave can be a physical disturbance, such as a ripple in water or a vibration in a string, or an abstract disturbance, such as a sound wave or electromagnetic wave. Waves transfer energy without transferring matter.
What else can I help you with?
Does a periodic disturbance of a medium describe a wave?
No. If it happens that the disturbance propagates through the medium, i.e. spreads out from the disturbed point, then the phenomenon that travels away from the disturbance and through the medium describes the wave.
When does the avg velocity become 0?
Average velocity is 0 when an object returns to its starting point after moving away from it. This means that the total displacement of the object is 0, resulting in an average velocity of 0.
Can an average speed of moving object be zero?
Yes, an average speed of a moving object can be zero if the object returns to its starting position within the same amount of time it takes to move away from it. For example, if a car travels 10 miles away from its starting point and then travels back 10 miles in the same amount of time, its average speed can be zero.
Why do waves travel outwards in a circular pattern away frojm the original disrubance?
Waves travel outwards in a circular pattern away from the original disturbance because of the principle of wave propagation. When a disturbance creates a wave, the energy is transferred in all directions equally, causing the wave to spread out in a circular manner. This circular pattern is a result of the wavefront moving outward in all directions at the same speed.
What is Energy moving away from a central source?
Energy moving away from a central source is typically referred to as radiation. This can manifest in various forms such as light, heat, or sound that emanate outwards from the source. The energy spreads out in all directions as it moves away from the central point.
A blank is a disturbance that moves away from its starting point?
It is a wave
What is an antapex?
An antapex is a point opposite a solar apex.
Does a periodic disturbance of a medium describe a wave?
No. If it happens that the disturbance propagates through the medium, i.e. spreads out from the disturbed point, then the phenomenon that travels away from the disturbance and through the medium describes the wave.
Is displacement another word for situation?
No, displacement refers to the act of moving something from its original position or the distance between the starting point and the ending point. Situation refers to the circumstances or conditions in which someone or something finds themselves.
When does the avg velocity become 0?
Average velocity is 0 when an object returns to its starting point after moving away from it. This means that the total displacement of the object is 0, resulting in an average velocity of 0.
What does a line sloping upwards mean in a distance graph?
A line sloping upwards in a distance graph indicates that the object is moving away from the starting point, and the distance from that point is increasing over time. The steeper the slope, the faster the object is moving. If the line is straight, the speed is constant; if it curves, the speed may be changing.
Why do galaxies move away from the earth?
Our galaxy is expanding and according to the cosmological principle, the further away a galaxy is the faster it is moving away. The galaxies are not getting further apart because they are moving through space but because space itself is expanding. Like raisins in rising dough. The raisins themsleves are not moving away from the other raisins but the dough itself is expanding, so every raisin sees the other raisins moving away from it.
Can an average speed of moving object be zero?
Yes, an average speed of a moving object can be zero if the object returns to its starting position within the same amount of time it takes to move away from it. For example, if a car travels 10 miles away from its starting point and then travels back 10 miles in the same amount of time, its average speed can be zero.
What direction is an object headed when in linear motion?
It is moving either one way or the other. Linear motion is straight line motion. Either the object is moving toward point A or away from it toward point B.
What direction is in object headed when in linear motion?
It is moving either one way or the other. Linear motion is straight line motion. Either the object is moving toward point A or away from it toward point B.
What does the slope of the line on a position vs time graph tell you about abject's speed?
The slope of the line on a position vs. time graph represents the object's speed. A steeper slope indicates a higher speed, while a shallower slope indicates a lower speed. If the slope is positive, the object is moving away from the starting point, and if it's negative, the object is moving back toward the starting point. A flat line (zero slope) means the object is at rest.
