Seven-year-old Vincent Butterfield        the only way was to cut off his hair in support of his best friend Zac who lost his hair through chemotherapy(化疗).
Zac Gossage is receiving treatment but        goes to Union Central Elementary School in Missouri every day,        that's where he gets to play on the swing with Vincent. Vincent found out that Zac might        his hair because of the chemotherapy treatment. So one day, he showed up in the first grade class wearing a       . He said to his teacher Mrs. Koester, "I have a surprise for Zac." And he pulled off his cap and other        saw that he already had all his hair       off.
"I did it just to make Zac feel he's not the only one without any      ." said Vincent.Vincent has also been raising money for his best friend after learning how        his chemotherapy treatments are. He asked his mother to make        than 20 scarves and gloves. He and his mother        them at the price of 10 dollars each, raising over $200 for Zac. The encouragement from Vincent seems to be working. Though Zac is receiving treatments, he has        missed any days of school. He knows that Vincent is out on the playground, waiting for him at break.
When asked        friendship was, Vincent looked at his friend Zac, thought for a(an)        and responded,"It's a beautiful thing."

PTC是一种新型的半导体陶瓷材料,它的发热效率较高,PTC有一个人为设定的温度。当它的温度低于设定温度时,其电阻值会随它的温度升高而变小;当它的温度高于设定温度时,其电阻值随它的温度升高而变大。如图1所示的陶瓷电热水壶就使用了这种材料。它的工作电路如图2所示,R0是定值电阻,其阻值不受温度的影响。RT是PTC的电阻,它的电阻值与温度的关系如图3所示。该电热水壶在RT设定温度状态工作时,电路消耗的总功率1100W。

(1)R0的阻值为多少?

(2)当RT的温度为130℃时,电路中RT的实际功率为多少?
