What is the final temperature of 5kg of water, with an initial temperature of 5oC, after 50kJ of energy has been transferred to it. The specific heat capacity of water is 4200 J/kgoC

Explanation:

Given that,

Mass, m = 5 kg

Initial temperature of water,

Heat transferred, Q = 50 kJ = 50,000 J

The specific heat capacity of water is 4200 J/kg°C

We need to find the final temperature of the water. The heat transferred in the process is given by :

So, the final temperature of water is .

if the forces acting on an object are unbalanced, the object will accelerate in the direction of the net force on the object.

explanation:

this is best explained by having an understanding of newton's second law, which states that f=ma. you see, when the forces are unbalanced, net force (sum of all forces) is not zero. therefore making it necessary for the object to have an acceleration in the direction of the net force.

i would say
