Answer:
A vibration is the primary source of a sound.
A cascade effect is an inevitable and sometimes unforeseen chain of events due to an act affecting a system. If there is a possibility that the cascade effect will have a negative impact on the system, it is possible to analyze the effects with a consequence / impact analysis. An example of the cascade effect caused by the loss of a top predator is apparent in tropical forests. When hunters cause local extinctions of top predators, the predators' prey's population numbers increase, causing an overexploitation of a food resource and a cascade effect of species loss. Another example is a lake system with four trophic levels, the model predicts with the removal of the top carnivore, the primary carnivore numbers will increase, in turn, reducing the number of herbivores, increasing the phytoplankton abundance, and decreasing the levels of mineral nutrients. The effects show a positive/ negative change in trophic level structure as it moves down.

Answer:
<h2>22500 kg.m/s</h2>
Explanation:
The momentum of an object can be found by using the formula
momentum = mass × velocity
From the question we have
momentum = 1500 × 15
We have the final answer as
<h3>22500 kg.m/s</h3>
Hope this helps you
Answer:
Explanation:
In microwave, there are waves called "microwaves" as per the name. So, The heating of food is done with the help of waves. Radiation is "the transfer of heat through waves". That is why the process of heating food in a microwave is "Radiation".
