Answer:
Iron
Explanation:
H = mc∅
Above equation can be used here to find the answer to the question. this equation gives us the relationship between the heat energy supplied to a material and the temperature difference that the material would go through according to its mass.
here H is the Heat energy supplied to the material. m is the mass of the material. c is the specific heat capacity of the material and ∅ is the temperature difference applied to the material. we are given that H= 337,500J , m = 50 kg and ∅ = 15 °C. so from the equation now we can calculate the value of c. after calculating c we can find the material because c is an unique value for a particular material. no two materials have the same c value.
c = 337500/(50*15)
c = 450 J/(kg°C) - Iron (google the heat capacity value to find the answer Iron)

Is isn't a stream or rushing water. Or something like that?
Answer:
16
Explanation:
The formula for the force of attraction between two charges is , where k is a constant, is the first charge, and is the second charge. As you can see, if the radius or distance increases by 2, the force decreases by 4 because it grows exponentially. However, if the charge of one of the particles increases by 2, the force between the two also increases by 2. Therefore, the new force will be 8*2=16. Hope this helps!
