A group of scientists claim that a new type of fuel will help reduce greenhouse gas emissions. to evaluate this claim you can a. calculate the price of producing the fuel. b. study the effect of a fuel spill on wetland ecosystems. c. determine the efficiency of the fuel in different types of engines. d. test the amount
Explanation:
power = Force × distance /time
power = 944N × 12.4m/36secs
power = (944×12.4/36)Nms—¹
power = 390.2Nms—¹ or 390.2Watts or 390.2Js—¹
Answer:
54 N
Explanation:
We have two positive charges 12uC and 5 uC ,they are kept at a distance of 10cm.
We have a relation for force between two charges q1,q2 as
Value of k is 
On substituting the values into the equation we get,
Hence the force between them is 54 N.
I assume the element has 5 valence electrons (not neutrons). The similar properties are shared between y and z since they have the same number of valence electrons. This is what is primarily responsible for chemical behavior.
Hi, thank you for posting your question here at Brainly.
Electricity is the flow of electrons due to a potential difference called voltage. The electrons naturally flows from a higher to a lower potential. Thus, the electrons flows from the positive to the negative terminal.
