Best Answer

The CV2 number is an additional layer of security added to Visa, MasterCard, and American Express credit cards for telephone and online purchases. The CV2 number for Visa and MasterCard credit cards is three numbers found on the back of the card. The CV2 on the American Express is four numbers found on the front of the card slightly above the credit card number.

Can you measure electrical energy in joules?

The energy stored by a capacitor, for example, is given by the expression E = [1/2]CV2, where C is the capacitance in farads and V is the voltage in volts. E will be expressed in joules.


What is the mass of a 100 kg object while traveling 90 percent the speed of light?

Mass = (Rest mass) / sqrt( 1 - v2/c2 )V = 0.9 cv2/c2 = 0.811 - v2/c2 = 0.19sqrt( 0.19 ) = 0.4359Mass = (rest mass) / 0.4359 = 2.294 x (rest mass)For a rest-mass of 100 kg, that's 229.4 kg at 0.9 c .


How do you find out the amount of joules?

Where? And in what context?The joule is the metric unit of energy and work. If you multiply a force (in newtons) by the distance (in inches) through which that force is applied, you can calculate the amount of work in joules that has been done. But there are others ways to calculate energy or work. For example, the amount of electrical energy stored a capacitor is given by the expression E = [1/2]CV2, where C is the capacitance in farads and V is the voltage in volts. The result is in joules.
