Given that,

Mass of water, m = 5 kg

The temperature increases from 20℃ to  40℃.

Specific heat capacity of water is 4200 J kg⁻¹ k⁻¹

To find,

Heat energy required to raise the temperature.

Solution,

The formula for the heat energy required to raise the temperature is given by :

Q=mc\Delta T\\\\=5\times 4200\times (40-20)\\\\=420000\ J\\\\=420\ kJ

So, the heat energy required is 420 kJ.

2 times as many items can be uniquely identified

Explanation:

Option 'C' is the answer. because

if we use 6 bit binary sequence

then

No. of Unique address will be = 2 ^ 6  = 64

as we increase the bit by 1. Now total bits are 7.

so

No. of Unique address for 7 bit Sequence = 2 ^ 7  = 128

So,

128 is double of 64, that is 2 times greater value than 64.
