Suppose i create a two-slit interference pattern using light with some wavelength lambda and slits with some separation d. if i were to increase lambda, what would happen to the interference pattern on the wall? the pattern would spread out nothing would happen to the pattern the pattern would compress

What is relative velocity? in which condition is relative velocity known by adding the velocity of the first body and that of the second body

A1000-kg car is moving at 30 m/s around a horizontal unbanked curve whose diameter is 0.20 km. what is the magnitude of the friction force required to keep the car from sliding?

Two kilograms of air within a piston–cylinder assembly executes a carnot power cycle with maximum and minimum temperatures of 800 k and 300 k, respectively. the heat transfer to the air during the isothermal expansion is 60 kj. at the end of the isothermal expansion the volume is 0.4 m3. assume the ideal gas model for the air. determine the thermal efficiency, the volume at the beginning of the isothermal expansion, in m3, and the work during the adiabatic expansion, in kj.
