物理基礎の問題です! 類題の(4)を教えてほしいです!! よろしくお願いします🙇🏻‍♀️՞

例題① 電熱線による発熱 1kWh=10Wh=3.6×10J 3.6×10³ J ある長さの電熱線に100Vの電圧をかけると, 消費電力が400W であった。 次の問いに有効数字2桁で答えよ。 ただし, 電熱線の単位長さあたりの抵抗値 は変わらないものとする。 (1) 電熱線には何Aの電流が流れるか。 (3) (2)電熱線の抵抗値は何Ωか。 かかるか。 ただし, 電熱線の発熱量の30%は周りに逃げるものとし, 水の この電熱線を用いて, 16℃の水300gをあたためて100℃にするには何s 比熱は 4.2J/ (g・K) とする。 Gato 指針 (3) 水が得た熱量は, 電熱線で発生したジュール熱の70%に等しい。 解 (1) 電熱線に流れる電流をI [A] とすると,「P=VI」より、 400 W 400W =100 VXI よって, I= p.199式(7) =4.0A 100V p.192式(3) (2) 電熱線の抵抗値を R [Ω] とすると, オームの法則 「V=RI」 より (3)かかる時間を [s] とすると,「Q=Pt」 と 「Q=mcAT」 より, 100V よって, R= 100V=R×4.0A =25Ω 4.0 A p.125式(3) よって, t=3.78×10°s≒3.8×10's 84- p.199式(8) 400Wxtx0.70=300g×4.2J/(g・K)×(100-16) K 類題1 例題①の電熱線を、 元の80%の長さに切って, 100Vの電圧をかけた。次の 問いに有効数字2桁で答えよ。 (1) 電熱線の抵抗値は何Ωになるか。 (2) 電熱線には何Aの電流が流れるか。 (3)このときの電熱線の消費電力は何Wになるか。 (4) 例題1の(3)と同じようにして水をあたためたとき, かかる時間は元の何倍か。 20
