WebSo we say if y=x^2 then dy/dx=2x and integration being the reverse of differentiation, using notation 'Integral of x' as I (x), then I (2x)=2* (x^2)/2 + K (we always add a constant in integration for the missing part. So perhaps the (gravitational) force is f=I (something) so that it ends up squared. Force is a funny animal. WebDec 14, 2024 · Gray – Unit of Absorbed Dose.

WebThe SI unit for measuring radiation dose is the gray (Gy), with 1 Gy = 1 J of energy absorbed per kilogram of tissue. In medical applications, the radiation absorbed dose (rad) is more often used (1 rad = 0.01 Gy; 1 rad results in the absorption of 0.01 J/kg of tissue). The SI unit measuring tissue damage caused by radiation is the sievert (Sv). WebAug 15, 2024 · The gray (Gy) is an SI unit for the absorption of 1 J radiation energy by one kg of material. The rad was a popular unit, which is the absorption of 100 erg of radiation energy by one gram, (1 Gy = 100 rad). diwali for early years video https://prosper-local.com
