Answer:
The huntsman was shocked! But she was the Queen and what could he do? The next day he took Snow White into the woods. As he drew his knife to slay her, Snow White turned around.
“Look,” she said, taking something out of her pocket. “You have always been good to me.” She held in front of him six perfect arrowheads that she had carefully shaped. “Do you like them?” she said. “They are for you.”
“Snow White,” said the huntsman. “I cannot do this!”
“You can take these,” said Snow White.
"That's not what I mean," said the servant. He dropped to his knees. “How can I say this to you? The Queen, your step-mother, ordered me to kill you,” he said. “But I cannot!”
“She did what?” Snow White called out with alarm.
“You must run away!” said the huntsman. “Far into the woods. Now! And never come back to the castle!”
Snow White turned and ran into the woods as fast as she could. Deeper and deeper she ran. It was getting dark, and the wolves were starting to howl. She tripped and her skirt was torn. Tall tree branches seemed to reach down to the very ground to grab her. She was scratched, bleeding and scared. Yet she ran on and on.
Then all of a sudden, far away, there was a light. Who was living so deep in the woods? She stepped up closer. It was a cottage! Yet no sound came from the cottage, only light from the windows.
Answer:
In 1909, Robert Millikan and Harvey Fletcher conducted the oil drop experiment to determine the charge of an electron. They suspended tiny charged droplets of oil between two metal electrodes by balancing downward gravitational force with upward drag and electric forces.
