The frequency and period of any wave are reciprocals.
Frequency = 1/period and Period = 1/frequency .
That means that the product of (frequency) times (period) of any wave is always the same. The product is always ' 1 ', with no unit.
Any wave's frequency and period are reciprocals. Time period is the inverse of the frequency.
What is frequency?Frequency is defined as the number of cycles per second. The time to make one complete cycle is frequency. Its unit is Hertz.
Frequency and period are related as;
Period = 1/frequency
Frequency = 1/period
Hence,any wave's frequency and period are reciprocals.

Which of the following happens when unbalanced forces act on an object? The object remains stationary. The object moves with the same velocity. The object moves in the direction of the stronger force. The object's speed and direction of motion remain unchanged
The object move in the direction of the stronger force is the answer.
What are balanced and unbalanced forces?balanced force when two individual forces are of the same magnitude and point in opposite directions. We talk about unbalanced forces on an object only if there is a single force of the same magnitude but not balanced by opposite forces.
If the resultant force of all the forces acting on an object is not zero, the forces will be imbalanced. Power. These forces change the stationary state or the uniform movement of the body. Example: Push a toy car lying on the ground and it will start moving with one side force.

The many volcanoes located along the edge of the Pacific Ocean make up the Ring of Fire. How does subduction play a role in the volcanic activity in the Ring of Fire? Make a full paragraph!
Answer:
When two plates collides of varying densities, one tends to subduct introducing volcanic material to the earth surface.
Explanation:
The ring of fire is a geographical area where seismic and volcanic activities are prevalent. This region extend around the edge of the pacific plates and including smaller plates like the Juan de Faca plate, coccus plate and the Philippine plate . The ring of fire is a place known for earthquake and volcanism due to the active plate boundary.
The plate boundaries around the rings of fire are known for subduction activities.
Usually, in a convergence boundary where continental crust collides with oceanic crust the more dense oceanic crust tends to subduct. The continental crust is less dense and possess more buoyancy. The less dense and buoyant nature of the continental crust will cause it to override the oceanic crust.
Generally, when oceanic crust and continental crust collides the oceanic crust subduct reaching the aesthenosphere area, Aesthenosphere material like magma are introduced to the earth surface through the subduction zone. The magma may creep through cracks and fissures or erupt to the earth surface. The subduction zone form trenches which is a prerequisite for creating mountains, volcanisms and earthquakes.

Moon can go through phases from quarter to half to three-forth to a full moon.
What is Full moon?When the moon is in its full brightness and its whole disc is illuminated.
The Moon reflects its light from the Sun. Only the part of the Moon that faces the Sun is visible. As the Moon revolves around the Earth, its shadow covers part of its surface. The full moon occurs when the entire moon is visible. A quarter way through the cycle, half of the moon is visible, known as the first quarter. When the Moon seems to disappear, which is known as a new moon or no moon.
Thus, Moon can go through phases from quarter to half to three-forth to a full moon.

Thank you!
The greatest displacement is either option A or C, as both result in the person being displaced by 3 meters north of their starting point.
Explanation:The question asks which of the given options describes the greatest displacement. Displacement is a vector quantity that describes the change in position of an object. It is important to understand that displacement takes into account the initial and final positions, not the total distance traveled.
A) walking 3m east, then walking 3m north, then 3m westB) walking 3m east, then 3m south, then 3m northC) walking 3m north, then 3m south, then walking 3m northD) walking 3m north, then 3m west, then 3m southFor option A, the displacement would result in the person being 3m north from their starting point, since the east and west movements cancel out. Option B results in the person being 3m east of the starting point, as the south and north movements cancel each other out. Option C essentially brings the person back to their starting point after the first two movements, and then displaces them 3m north, similar to option A. Finally, option D involves the person moving 3m in each of the cardinal directions, which would bring them right back to their starting point, resulting in a displacement of 0 meters.
The correct answer is either option A or C, as both result in the greatest displacement, which is 3 meters north.

Which question about the discovery of the earth revolving around the sun could be best answered using scientific inquiry
In order to scientifically demonstrate that Earth is spherical, one can measure the Earth's curvature, conduct gravity experiments, utilize satellite imagery, and observe the change in constellations at different latitudes.
Explanation:The question that could be best answered using scientific inquiry about the discovery of the Earth revolving around the sun would be: Give four ways to demonstrate that Earth is spherical.
Measure the Earth's curvature using a long-distance view, such as observing a ship disappearing over the horizon.Conduct experiments with gravity, such as observing the shape of water in a container or using a plumb line to measure verticality.Utilize satellite imagery or photos taken from space to show the Earth's spherical shape.Observe the change in constellations as you move away from the equator, which can only be explained by Earth's sphericity.
