Answer:
C. a dense region of positive charge existed somewhere in the atom.
Explanation:
Physicist Ernest Rutherford created the gold foil experiment in which he shot a beam of alpha particles at a sheet of gold foil, which then sent a few of the particles flying after they were deflected. Based on the information gathered after completing this experiment, Rutherford concluded that a dense region of positive charge existed somewhere in the atom.

Answer:
0.69 ohm
Explanation:
Heat generated per second, H = 50 cal/s
Potential difference, V = 12 V
Let R is the resistance of coil.
The formula for the heat is given by
![H = \frac{V^{2}}{R}t](https://tex.z-dn.net/?f=H%20%3D%20%5Cfrac%7BV%5E%7B2%7D%7D%7BR%7Dt)
![50\times 4.186 = \frac{12^{2}}{R}\times 1](https://tex.z-dn.net/?f=50%5Ctimes%204.186%20%3D%20%5Cfrac%7B12%5E%7B2%7D%7D%7BR%7D%5Ctimes%201)
R = 0.69 ohm
