Alight source of 460 nm wavelength illuminates a single slit of width 2.80×10−2 mm , producing a standard diffraction pattern on a screen, in which the intensity is 1.03×10−4 w/m2 at the very center of the pattern (θ= 0∘). at a point on the screen for which θ = 1.20 ∘, determine the intensity. express your answer to three significant figures and include the appropriate units.

In order to do work, the force vector must be question 1 options: in a different direction than the acceleration vector. in a different direction than the displacement vector. in the same direction as the displacement vector and the motion. in the same direction as the acceleration vector.

Achild has maximum walking speed of 1.6 m/s. what is the length of the child's legs? 0.26 m

Cyclotrons are widely used in nuclear medicine for producing short-lived radioactive isotopes. these cyclotrons typically accelerate h- (the hydride ion, which has one proton and two electrons) to an energy of 5 mev to 20 mev. this ion has a mass very close to that of a proton because the electron mass is negligible—about 1 2000 of the proton’s mass. a typical magnetic field in such cyclotrons is 1.9 t. (a) what is the speed of a 5.0-mev h-? (b) if the h- has energy 5.0 mev and b = 1.9 t, what is the radius of this ion’s circular orbit?
