Il est bien connu que les jeunes adolescents peuvent se montrer rebelles face à leurs parents à la maison. Les jeunes ont tendance à vouloir toujours plus de libertés et à pousser les limites de ce qui es...

1/R_t= 1/R₁ + 1/R₂ The equation for resistors in parrallel. If R₁ and R₂ are both 2 ohms then 1/R_t = 1/2 +1/2 = 1 so R_t = 1 ohm....

You can use E= hf_o + KE and E=hf (Einstien's equations) to work how the frequency of a photon, where f_o is the threshold frequency and h is Planck's constant.

To find the minimum point of this curve you need to differentiate y and set it equal to zero before solving for x. If the questions does not say otherwise give your answer to 3 s.f. dy/dx = 3e^3x -12e^2x ...

In this algebraic problem, we are faced with two unknowns (x's) on both sides of the equation. Remember that what we do to one side, we must also do to the other side. So to tackle this, we will first foc...
