The energy transferred is given as the product of power and time. The 1.4 kW kettle with boiled water produces 378 kJ of energy.
<h3>What is energy?</h3>
Energy is the quantitative property that determines the work done by the body in the form of heat and light.
The image showing the kettles with time and power is attached below.
Given,
Power of the kettle = 1.4 kW
Time taken = 4.5 minutes
If power = energy ÷ time
Then, energy = power × time
= 1.4 × 0.075
= 0.105 KWh
Therefore, 0.105 kWh or 378KJ is the energy transferred.

Answer:
Option O = H₂O
Explanation:
Chemical reaction:
2K + 2H₂O → 2KOH + H₂
In this balanced chemical equation we can see that water is the only compound that consist of two hydrogen atom and one oxygen atom. H : O
2 : 1 .
In case of KOH two hydroxyl and two potassium atom are present and ration is K:OH 1:1.
Answer:
The pitcher plant and the Venus flytrap are examples of plants that are carnivorous. Plants produce food and oxygen during photosynthesis.
Explanation:
Answer: Thus the mass, in grams, of 27 moles of smooth muscle myosin is 12960000 grams
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to the molecular mass, occupies 22.4 L at STP contains avogadro's number 
of particles.
Molecular mass of protein = 480,000 g/mol
Thus 1 mole of protein weighs = 480,000 g
So 27 moles of protein weighs = 
Thus the mass, in grams, of 27 moles of smooth muscle myosin is 12960000 grams
Frosty the snowman is GUILTY. he broke into a room that was 20 degrees F, then moved into the room with the safe, which was 65 degrees F, above the freezing point, and no snow can not melt at 65 degrees. as he was tromping through the hot house, he began to turn back into liquid because he began melting in the heat. so all evidence points towards the fact that frosty did it.
