Its not that hard.
Half of the inch part is 1/2 inch which is also 4/8.
half of the 3/4 part is 3/8 you get by multiplying the denominator by 2.
Put it all back together and you get the 4/8 part and the 3/8 part so in total its 7/8 of an inch.
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.
