Enthalpy of Neutralisation: the energy change a system experiences when one mole of water is formed from the neutralisation of an acid with an alkali under standard conditions.Standard conditions: 298K, 1...
An increase by 20% is the same as multiplying by 1.2Therefore, 35 x 1.2 = 42
f(x) = 2sin2(2x)Therefore, using the chain rule: f'(x)=2 x 2cos(2x) x 2sin(2x)(The 2 at the front arises from the constant 2, at the start of f(x), the 2cos(2x) comes from differentiating sinSHAnswered by Sam H. • Maths tutor4636 Views
An object will remain at rest or constant velocity if all the forces acting upon it are equal (net force=0N).
If wavelength = 0.1nm, we know (as E=hc/λ), the energy provided by each photon, E= 1.99x1015 J .Therefore, if they hit the panel at a rate of 2.51x1015SHAnswered by Sam H. • Physics tutor1799 Views
