If you have dirty coins, Rules # 1 through 100 are DO NOT TRY TO CLEAN THEM AT HOME. Any household chemicals you might use will damage the coin itself and significantly reduce its value. The most you should do is to dab a dirty coin with some distilled water and a soft cloth. If you have a coin known to be valuable that is encrusted in dirt or other crud, youll need to contact a coin dealer about finding a company that specializes in cleaning. They have the right tools and techniques to avoid damage. Such a firm was used to remove 150 years of ocean grot from the coins found on the S.S. Pacific, for example.
What is a joule equal to in terms of kg M and S?
-
Joule (unit) One joule equals the workdone (or energy expended) by a force of one newton (N) acting overa distance of one meter (m). One newton equals aforce that produces an acceleration of one meter per second(s) per second on a one kilogram (kg) mass.Therefore, one joule equals onenewton•meter.
-
The unit of energy in the International System of units(SI). One Joule is equal to one kilogram times square meter oversquare second, in short: 1 J = 1 kgm2/s2.
Furthermore, what unit is kg/m2 s? SI Derived and SI Compatible Units
Derived Unit Measures Derivation newton (N) force kg·(m/s2) pascal (Pa) pressure N/m2 joule (J) energy or work N·m watt (W) power J/s
Accordingly, what are the units that make a joule?joule. The SI derived unit used to measureenergy or work. One joule is equal to the energy used toaccelerate a body with a mass of one kilogram using one newton offorce over a distance of one meter. One joule is alsoequivalent to one watt-second.
What is a joule per second equal to?
Yes, one Watt is defined as 1 Joule of energyper 1 second. Power is defined as work perunit of time. Power=work donetime needed. The SI units for work andtime are Joules and seconds, respectively. One Wattwas defined as a power of 1 Joule per second.
