Physics Class – XII Dual nature of matter Q.1. State the dependence of work function on kinetic energy of electrons emitted in a photocell. If the intensity of incident radiation is doubled‚ what changes occur in the stopping potential and photoelectric current? Q.2. How does the maximum kinetic energy of the emitted electrons vary with the work function? Q.3. the frequency of incident radiation is greater than the threshold frequency in a photocell. How will the stopping potential vary if

Heat exhaustion and heatstroke As days slowly begin to heat up it is important to stay cool and keep hydrated across the screaming scorching sun. Summer time usually means longer days and if you live close to the equator you know about the 100+ degree weather that comes with it. Without the proper precautions you could easily fall to heat exhaustion or far worse a heat stroke. Athletes are more prone to this type of sudden illnesses because of the constant running and exercise they do on a daily

up to 20%. The purpose of them is to hold the heat below within the property‚ reducing heat loss to the roof void and outside but also reducing the amount of heating needed to maintain the property at an ideal temperature. With insulation‚ the property will be warmer‚ more comfortable and it will cost less to heat. How loft insulation reduces heat loss? Heat will always flow from a warm area to a cold one. The colder it is outside‚ the faster heat from your home will escape into surrounding air

Matter of Mogharrabi‚ 19 I&N Dec. 439 (BIA 1987) Decided by Board June 12‚ 1987 FACTS: Mogharrabi and his wife were permitted into the United States from Iran as nonimmigrant students. They stayed in the United longer than the initial time allowed and arrangements were made for them to be deported. Mogharrabi filed for asylum to void the deportation for fear of his persecution because of his political opinion if he were to return to Iran. He claimed a well-founded fear of persecution based

Is The Miami Heat a Dynasty? A sports dynasty is a team that enjoys a period of dominance over the sport‚ generally by winning multiple championship titles. The age old question is what classifies a team as a dynasty? Does the team have to win back to back titles? How many titles must they have? Will they be this dominant in the future? The list of questions sport analysis have is endless. The issue remains that people argue over what defines a team as a dynasty. Todays most popular argument is
