 The uncertainty in the momentum Δp of a golf ball stroked by a player which is traveling at 50m/s is  1×10−6 of its momentum. What is its uncertainty in position Δx? Mass of the golf ball was measured as 250 g 

Psi(x)= Asin(2πx), for what value of A is the wave function normalised

A system is defined by the wavefunction ψ(x) = Acos(2πx/L) for –L/4 ≤ x ≤ L/4.

Determine the normalization constant A and the probability that the particle will be

Found between x = 0 and x = L/8?

Suppose the temperature of a COVID positive patient skin is recorded as Tskin = 102 °F. Determine the wavelength at which the radiation emitted from the skin reaches its peak.

 Write the Wiedemann Franz law.

A planet of mass 1.000 × 10²⁶ kg, has a moon of mass 2.100 × 10²² kg and orbital radius 3.550 × 10⁵ km. The orbit of the moon is assumed to be circular.

Determine the distance, from the centre of the planet, the point at which the resultant gravitational field is zero.
