Gout and Diet. Gouty arthritis is usually an extremely painful attack with a rapid onset of joint inflammation. The inflammation is precipitated by the deposition of uric acid crystals in the lining of the joint (synovial lining) and the fluid within the joint. Intense joint inflammation occurs when white blood cells engulf the crystals of uric acid and release chemicals that promote inflammation.
Which way does the electric field point around the positive terminal of an alkaline battery? E.20 The electric field points away from the positive terminalâs surface. 21. Which has the stronger electric field between its two terminals: a 1.5-V AA battery or a standard 9-V battery? Explain. E.21 The 9-V battery has the larger voltage gradient and therefore the stronger electric field because its two terminals have a greater voltage difference and a shorter distance between them. 22. You have 100 AA batteries.
The electric field a distance r away from a point charge Q is given by: Electric field from a point charge : E = k Q / r2. The electric field from a positive charge points away from the charge; the electric field from a negative charge points toward the charge. Like the electric force, the electric field E is a vector. If the electric field at a particular point is known, the force a charge q experiences when it is placed at that point is given by : F = qE. If q is positive, the force is in the same direction as the field; if q is negative, the force is in the opposite direction as the field.
