There is a variable, state_capitals, that refers to a dictionary that maps U.S. states to their capitals, and another dictionary, provincial_capitals, that maps Canadian provinces to their capitals. Associate a dictionary that maps states or provinces to their respective capitals with a variable, regional_capitals.
Explanation:
The below code is done in python.
{provincial_capitals.keys} + (state_capitals.keys) == regional_capitals
regional_capitals = {}
regional_capitals.update(state_capitals)
regional_capitals.update(provincial_capitals)
Answer:
The correct options are;
Mechanical
Faraday
Explanation:
The principle of working of electric generators is to convert kinetic energy, which is the energy present in the spinning turbine into electrical energy. Electricity is generated by the use of the electric generators has the largest share of all forms of electricity generated electricity and it is based on Faraday's law of of induction, which states that Emf = N×(ΔФ/Δt)
Where;
Emf = The induced voltage
ΔФ = Change in magnetic flux
Δt = Change in time.
Therefore, we have;
Traditional power-generating stations do not store electrical energy. In such power stations, the original energy source spins a turbine which an electric generator. It converts <u>mechanical </u>energy into electrical energy using a fundamental principle of physics called <u>Faraday's</u> law.
Answer:
a. True
Explanation:
The fractional_part function divides the numerator by the denominator, and in turn returns just the fractional part, which is usually a number between 0 and 1.
When the denominator is 0, it produces an error result, instead of attempting the division, the function can be programmed to return "Math Error: cannot be divided by zero", as shown in the following Python code;
def fractional_part(numerator, denominator):
if denominator == 0:
return "Math Error: cannot be divided by zero"
return (numerator % denominator)/denominator
Answer:
replace()
Explanation:
The history object in javascript corresponds to browsing history.
It has the following methods for navigating through the history list:
back(): Go back in the history list
forward(): Go forward in the history list
go() : Navigate to the currently pointed url in the history list. It takes a parameter which can either be a numeric index or a string which is matched with the history list content.
replace() is not a method in the history object.
