The right answer for the question that is being asked and shown above is that: "A. neutron; B. red giants; C. black holes; E. main sequence." The Chandra X-ray observatory is BEST equipped to search for neutron, red giants, black holes, <span>main sequence.</span>
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.
The direction in which the magnetic force is acting on the charge is upwards.
<h3>What is Magnetic force?</h3>
This is the attraction and repulsion which usually occurs during the motion of electrically charged particles.
In the magnetic field, the charge is moving to the left. Therefore the direction the magnetic force is acting on the charge is upwards which is gotten via right hand rule.

The actual weight of the stone is 11 N. It is based on the Archimedes principles.
<h3>What is Archimedes principle?</h3>
- Archimedes principle states that the up thrust by water on an object is equal to the weight of water displaced.
- Upthrust by water on an object= actual weight of object - weight inside water
<h3>What is the actual weight of the object, if its weight inside water is 9N and weight of water displaced is 2N?</h3>
Actual weight= weight inside water+ weight of water displaced
= 9N + 2N = 11N
Thus, we can conclude that the actual weight of the object is 11N.
