What triggers sweating? Sweating is your body’s mechanism to cool itself. Your nervous system automatically triggers your sweat glands when your body temperature rises. Sweating also normally occurs, especially on your palms, when you’re nervous. The most common form of hyperhidrosis is called primary focal (essential) hyperhidrosis. Where do humans sweat the most? The human […]

When a capacitor is connected to a battery? If an uncharged capacitor C is connected to a battery of potential V, then a transient current flows as the capacitor plates get charged. The flow of current from the battery stops as soon as the charge Q on the positive plate reaches the value Q = […]

Which of the following capacitor is polarized? Which of the following capacitors is polarized? 1) plastic-film 2) ceramic 3) mica 4) electrolytic 5) NULL What is the difference between polarized and nonpolarized capacitor? The most widely used polarized capacitor is electrolytic type. So basically the difference is change of the manufacturing process for more capacity. […]

How do rockets rotate? In flight, any rocket will rotate about its center of gravity, a point which is the average location of the mass of the rocket. Most rockets are symmetric about a line from the tip of the nose to the center of the nozzle exit. We will call this line the roll […]

What happens to torque if field is non-uniform? An electric dipole always experiences a torque when placed in uniform as well as non-uniform electric field. But in non-uniform electric field, dipole will also experience net force of attraction. So the electric dipole in non-uniform electric field experiences both torque and force. What is meant by […]

What makes it easier to push heavy things answer? Answer: When you push there is one component of force that adds to the weight of the body and hence there is more friction. When you pull the vertical component of force is against the weight of body and hence there is less overall friction. So […]
