Answer:

Explanation:

When we say anything is a wave, what exactly do we mean? The most intuitive and straightforward wave to envision is a water wave. A motion, more specifically, is a disturbance that propagates or travels away from its source. Water waves are caused by a disruption in the water's surface, such as a rock tossed into a pond or a swimmer splashing the surface continuously. The noise for sound waves is a rise of air pressure, which may be caused by the oscillating cone within a speaker. There are many kinds of disturbances in earthquakes, including surface disturbances and pressure disturbances under the surface. Even radio signals are best deciphered by using a comparison of sea waves Water waves are helpful to visualize since they are more than just a mental picture. The amplitude, period, frequency, and energy of water waves are all the same as they are for all waves. A small set of underlying principles can be used to describe all wave characteristics.

An arrow is fired at a target on a high wall. Which statement correctly describes the change in the energy of the arrow as it mo
grigory [225]

Answer : Option C) The kinetic energy decreases as potential energy increases.

Explanation : As the target is fired high on the wall, the change in the energy that is observed as the arrow moves towards the target is kinetic energy starts to decrease as the arrow reaches nearer towards the target and the potential energy is observed to increase. So, in short the energy transformation is from kinetic energy from a moving arrow to potential energy when the arrow hits the target.

<h3>Answer:</h3>

               Option-B (Halide; oxide) is the correct answer.

<h3>Explanation:</h3>

                  <em> Halides</em> are those substances which contains negatively charged halide ion i.e. X⁻.

Examples:  F⁻ (Fluoride) , Cl⁻ (Chloride) , Br⁻ (Bromide) , I⁻ (Iodide) e.t.c.

                   <em>Oxides </em>are those substances which atleast containn one Oxygen atom.

Examples:  FeO (Iron Oxide), Cr₂O₃ (Chromium Oxide)

                   <em>Silicates</em> are those anionic substances which contains silicon and oxygen with general formula  [SiO. 4−x] n.

Examples: [SiO₄]⁻⁴ (Nasosilicate) , [Si₂O₇]⁻⁶ (Sorosilicates)

                   <em>Carbonates </em>are those substances which contains carbonate anion i.e. CO₃²⁻.

Examples:  Na₂CO₃ (Sodium Carbonate) , MgCO₃ (Magnesium Carbonate)

<h3>Conclusion:</h3>

                   As in NaCaAlF, F⁻ is present hence, it is an Halide and the presence of O in FeCrO makes it Oxide.

What is the relationship of inertia ang mass? Give one situation to show their relationship
nika2105 [10]

Answer:

The mass of a body is a measure of its inertia. It means larger the mass of a body, larger will be the inertia offered by the body to change its state of motion.

Example

When we kick a football, it flies a long way but at the same time if we kick a stone of the same size, it hardly moves, as the stone resists a change in its motion better than the football because of its more mass
