In a double-slit experiment the distance between slits is 4.4 mm and the slits are 0.97 m from the screen. Two interference patterns can be seen on the screen: one due to light of wavelength 460 nm, and the other due to light of wavelength 650 nm. What is the separation in meters on the screen between the m

State the right hand rule of the direction of magnetic field in a conductor carrying current

Laboratory experiments, observational field studies, and model-building are all examples of different forms of scientific investigations.  in what way do laboratory experiments primarily differ from other forms of scientific investigations?   a.  a laboratory experiment is the only accepted form of investigation within the scientific community.  b.  studies about how things behave in nature or studies involving very large objects are best answered through laboratory experiments.  c.  laboratory experiments involve the identification and control of variables.  d.  data can only be generated through laboratory experiments, not other forms of investigation.

Given the position vector of the particle r(t)=(t+1)i+(t^2−1)j+2t k, find the particle's velocity and acceleration vectors at t=1
