Water has a specific heat of 4.186 j/g°c. how much heat is required to increase 10.0 g of water from 25.0°c to 30.0°c? a 5.0 j b 21 j c 42 j d 209 j

D) 209 Joules

Explanation:

Using the equation below:

Q= heat gained

m= mass of the substance = 10.0 g

 = change in temperature =

c = heat capacity of water = 4.186 J/g ° C      

Putting in all the values we get:

Thus heat gained by 10 g of water is 209 Joules

a charge 3q is at the origin, and a charge −2q is on the positive x axis at x=a. part a where on the x-axis would you place a third charge so it would experience no net electric force? enter an expression for the exact answer, which will involve a square-root sign. (do not enter an approximate decimal answer.)

it is called kinetic energy
