it's alright ok fine ! no problem you most welcome!
the amount of heat need is 71060 Joules
ExplanationThe equation for the amount of heat needed to increase the temperature of water is as follows:

where E is the amount of heat
C is the specific heat capacity of water having a standard value of 4180 J/kg*K
T is the final ans initial temperature in kelvin
m is the mass
so
Step 1
given

a) convert the temperature into kelvin

now, replace in the formula

therefore, the amount of heat need is 71060 Joules
I hope this helps you
Answer:
currrent will be halved
Explanation:
v = ir
v/r = i multiply both sides by 1/ 2
