What is the power of a concave lens of focal length? The power of the lens is the reciprocal of the focal length of the lens. We know that, The focal length is the negative for the concave lens. Hence, The power of the concave lens is -0.5 D. What is the power of a […]
How the body gets rid of waste?
How the body gets rid of waste? Body Waste: Urine In your body, the excretory system helps to keep salts and urea from building up to dangerous levels and becoming toxic. The kidneys are two bean-shaped organs that remove these toxins from your blood and produce urine to carry them from the body. Why is […]

Do I need to discharge a capacitor?
Do I need to discharge a capacitor? You must discharge the capacitors before working on power supply circuits so you won’t get shocked. There are three different ways to discharge large filter capacitors in a power supply: with a screwdriver, the leads of a socketed 100 watt light bulb, and the leads of a high-wattage […]

What is angular momentum of a particle?
What is angular momentum of a particle? The angular momentum of a rigid object is defined as the product of the moment of inertia and the angular velocity.

Where is an 18 wheeler blind spots?
Where is an 18 wheeler blind spots? Because of the massive size of 18-wheelers and other big commercial trucks, they have many blind spots. For instance, 18-wheelers have a blind spot at the front-end of the truck, on both sides; just below and behind the driver-side window; and directly behind the truck. What are blind […]
How depletion region is formed in pn junction?
How depletion region is formed in pn junction? Movement of electrons to the p-type side exposes positive ion cores in the n-type side while movement of holes to the n-type side exposes negative ion cores in the p-type side, resulting in an electron field at the junction and forming the depletion region. When depletion region […]
