B) Under what condition is the force experienced by a current carrying conductor placed in a magnetic feild maximum? c) A proton beam is moving along the direction of a magnetic field. What fo The direction of force experienced by a current carrying conductor placed in a magnetic field depends on the direction of the current in the conductor and the direction of the applied magnetic field. This is given by FLEMING's left HAND RULE. Fleming’s left hand rule If the forefinger, middle finger and thumb of the left hand are stretched such that they are at right angles to each other, then:The forefinger gives the direction of the magnetic field. • The middle finger points in the direction of the current. • The thumb gives the direction of the force acting on the current-carrying conductor placed in the external magnetic field. (b) The force experienced by a current carrying conductor is maximum when the current and magnetic field are at right angles to each other. (c) Since the proton beam is moving along the magnetic field the force acting on the proton beam is zero. |

Steaming and baking are considered better cooking practices than boiling or frying.Give reasons.. |
|
Answer» When you fry food, the oils that you make use of are rich source of bad fats and saturated fats. These fats can ultimately lead to a number of conditions including obesity and heart related problems. The MOMENT you boil food in water it is obvious that all essential ingredients that are present in the food substances are MIXED with water and get drained at the end when draining water. This leaves the food product less nutritious in value. Baking or steaming on the other hand does not involve MAKING use of excess amounts of oils or water to cook food. So the natural ingredients of the food are always preserved and consumed by our body. It also MAKES the food more nutritious and healthy. |
