उत्तर : 1. "An ion"
व्याख्या :
Answer: A) An ion Explanation: An electrically charged atom or group of atoms formed by the loss or gain of one or more electrons is called an Ion. Cation: An ion is a cation (positive ion) if it is created by electron loss and is attracted to the cathode in electrolysis. Anion: An ion is an anion (negative ion) if it is created by an electron gain and is attracted to the anode. The valence of an ion is equal to the number of electrons lost or gained and is indicated by a plus sign for cations and a minus sign for anions. Ex: Na +, Cl−, Ca ++,...

उत्तर : 3. "Anemophily"
व्याख्या :
Answer: C) Anemophily Explanation: Pollination by wind is called Anemophily or Wind pollination. The process of the transfer of pollen from one individual plant to another, whereby the pollen is carried by air currents is called Anemophily. Almost all gymnosperms (Non-flowering plants) are anemophilous, as are many plants in the order Poales, including grasses, sedges and rushes.

प्र: Brightness of bulb depends on voltage or current? 1061 05b5cc68be4d2b4197774c390

उत्तर : 3. "Both A & B"
व्याख्या :
Answer: C) Both A & B Explanation: Brightness of bulb depends on both voltage and current. The brightness depends on power. Since we know that Power (P) = Voltage x Current = V I So whether you increase the current or the voltage the brightness will increase. Example Illustration: If you connect a long bulb and a round bulb in series, the long bulb glows but the round bulb does not. Both of them have the same current flowing through them (they are in series) but the long bulb has a greater voltage across it because it has more resistance (even though V= IR is not obeyed exactly, voltage drop does depend on the resistance). If you connect a round bulb and a long bulb in parallel, however, it is the round bulb that is brighter because now the voltage across both bulbs is the same but the current is larger through the round bulb (smaller resistance). Hence, the brightness of a bulb depends on power i.e, both voltage and current.
