Answer:
Current through circuit will be 
Explanation:
We have given source voltage v = 50 volt
Resistance 
Capacitance 
Time t = 5 sec
Time constant of RC circuit is given by 
We know that voltage across capacitor is given by 

So current will be 
So current through circuit will be

Answer:
Changes in the object's momentum (answer D)
Explanation:
A net force will cause an object to change its velocity, and that will affect the object's momentum, which is defined by the product of the object's mass times its velocity.
So, select the last option (D) in the given list.
The correct answer is A. He created a way of naming organisms based on genus and species
Explanation:
Carl Linnaeus created a simple but precise system for naming organisms of any species and kind. This system was known as binomial nomenclature and the names of organisms depend on two main elements: the genus and the species. The first element is a broad category that covers species with a common origin, and the second one is the species, which describes organisms that can reproduce and share many common features including DNA sequence. According to this, the correct answer is A.
