Physics, WILL GIVE BRAINLIEST: How do I solve this question?

The amount of heat needed to raise 250 g of a substance by 15 K is 2,930 J. What is the specific heat of the substance(J/kg*K)?

1.1 x 10^7
780
0.78
11,000

The answer to your question is   C = 781.33 J/kg°K or

                                                             780 J/kg°K

Explanation:

Data

 mass = 250 g

 ΔT = 15 °K

 Q = 2930 J

 C =  J/kg°K

Formula

 Q = mCΔT

 Solve for C

 C = Q/mΔT

Process

1.- Convert g to kg

              1000 g 1 kg

                250 g x

                x = (250 x 1) / 1000

                x = 0.250 kg

2.- Substitution

   C = 2930 / ( 0.250 x 15)

3.- Simplification

    C = 2930 / 3,75

4.- Result

     C = 781.33 J/kg°K  ≈ 780 J/kg°K

dopamine..

"it was found that some people who were taking the drug l-dopa to raise their levels of dopamine were developing schizophrenic-like symptoms supporting research a strength of the dopamine hypothesis is that there are many studies which have shown support for the neurochemical explanation."
