When the string is plucked, waves will travel from the point where it was plucked to the fixed ends, which cannot move and so must be nodes. The waves will reflect, and the superposition of the reflected ...

^A_Z X --> ^{A - 4}_{z - 2}Y + ⁴₂α
During alpha-decay, the nuclus emits an alpha particle which consists of two protons and two neut...

This question is dealing with phenomena of Redshift, where wavelengths are shifted due to movement between observer and event. The key information to extract from the question is we have a rest wavelength...

Ve = kQ/r = ((8.99 * 10^9) * (1.6 * 10 ^-19))/(0.5 * 10^-10) = 28.77 = 29 V

We are asked for the force acting on the car and we know from Newton's second law that F = ma Therefore, we need to calculate the acceleration first. We use a = (vf - vo)/(t - to) where vf = final speed, ...
