In a linked chain implementation of a stack ADT the performance of popping am emtry from the stack is

Mice21 [21]

Answer:

B.O(1)

Explanation:

When we are implementing ADT stack using linked chain we can pop an entry from the stack having O(1) time complexity because in linked chain we have the head or top pointer in linked chain only.Popping and pushing in stack happens on only one end that is top.So we have move to move top in linked chain to the next and delete prev node.

An electric kettle has the resistance of 30ohms what will flow when it connected to a 240v supply... find also the power rating

SVEN [57.7K]

Answer:

Power = 1920 Watts or 1.92 Kilowatts

Explanation:

Given the following data;

Resistance = 30 Ohms

Voltage = 240 Volts

To find power rating of the kettle;

Mathematically, the power consumption of an electric device is given by the formula;

Power = voltage²/resistance

Substituting into the formula, we have;

Power = 240²/30

Power = 57600/30

Power = 1920 Watts or 1.92 Kilowatts

Express the following binary numbers in hexadecimal. (a) %100011100101 (b) %1011001111 (show work)

Lapatulllka [165]

Answer:

$(100011100101)_{2} = (8E5)_{16} = %8E5$

$(1011001111) = (2CF)_{16} = %2CF$

Explanation:

Binary and hexadecimal values have the following pair equivalences.

$(0000)_{2} = (0)_{16}$

$(0001)_{2} = (1)_{16}$

$(0010)_{2} = (2)_{16}$

$(0011)_{2} = (3)_{16}$

$(0100)_{2} = (4)_{16}$

$(0101)_{2} = (5)_{16}$

$(0110)_{2} = (6)_{16}$

$(0111)_{2} = (7)_{16}$

$(1000)_{2} = (8)_{16}$

$(1001)_{2} = (9)_{16}$

$(1010)_{2} = (A)_{16}$

$(1011)_{2} = (B)_{16}$

$(1100)_{2} = (C)_{16}$

$(1101)_{2} = (D)_{16}$

$(1110)_{2} = (E)_{16}$

$(1111)_{2} = (F)_{16}$

We convert from binary to hexadecimal selecting groups of 4 binary from the binary code, from the least significant bits(at the right) to the most significant bits(at the left). The conversion is an hexadecimal "string" from the last group you converted to the first. So:

(a) %100011100101

$(0101)_{2} = (5)_{16}$

$(1110)_{2} = (E)_{16}$

$(1000)_{2} = (8)_{16}$

So

$(100011100101)_{2} = (8E5)_{16}$

(b) %1011001111

$(1111)_{2} = F_{16}$

$(1100)_{2} = C_{16}$

$(10)_{2} = (0010)_{2} = 2_{16}$

$(1011001111) = (2CF)_{16}$
