The choices for this question can be found elsewhere and as follows:
<span>(a) state a hypothesis
(b) list a procedure
(c) state the problem
(d) analyze the data
I think the correct answer from the choices listed is option C. </span><span>When designing an experiment, the first step is to state the problem because you cannot proceed to other parts without knowing the problem.</span>
Answer:
Explanation:
From the question we are told that
The wavelength is 
The length of the of the plate is 
The radius of the wire is 
Generally the diameter of the wire which is the distance between the glass plates is mathematically represented as
=> 
=> 
Generally the condition for constructive interference is mathematically represented as
=> 
=> 
=>
Work done = Force X Distance
3 430 000J = Force X 14m
Force = 3 430 000J / 14m
= 245 000 N
Hope this helps!
The first law is that every object stay at rest or stay in uniform motion in a straight line until it is forced to change its state by the action of an external force. This law is called law of inertia.
The second law is that the acceleration of an object is dependent upon two variables. the net force acting upon the object and the mass of the object. F= ma or force is equal to mass times acceleration. This law is known as the law of force and acceleration.
The third law is that for every action there is an equal and opposite reaction. every interaction there is a pair of forces acting on the two interacting objects. the size of forces on the first object equals the size of the force on the second object.
Hope this helps :)
can you please make this the brainliest answer it would really help . Thanks
Answer: object B is negatively charged, object C is positively charged and object D is also positively charged
Explanation: since unlike charges attract and like charges repel, for object A which is positively charged and B to attract B must be negatively charged and then for B which is negatively charged and C to attract C must be positively charged and for C and D to repel they have to be of thesame charge which means D is positive as well.
