Answer:
<h2>500 J</h2>
Explanation:
The kinetic energy of an object can be found by using the formula

where
m is the mass
v is the velocity
From the question
m = 1.6 kg
v = 25 m/s
We have

We have the final answer as
<h3>500 J </h3>

Answer:
Option A
250 degrees Celcius
Explanation:
If 1046J of heat energy is added to water, the water will experience a rise in temperature, at a rate that is directly proportional to its specific heat capacity.
Mathematically, this can be seen as 
Where C = specific heat of water = 4.184 J/g • °C.
Q = heat energy = 1046 J

Therefore, the increase in temperature that will be experienced, is for 250 degrees Celcius
