Fthe sun blows up at some instant and four minutes later we on earth sit down to eat lunch, those two events are separated by a spacelike interval. the sun's blowup cannot possibly have influenced us at the time we sat down, because it takes 8 minutes for light to reach us from the sun. and since the interval is spacelike, there must be a reference frame in which the two events are simultaneolls. find the speed of this frame relative to the sun-earth rest frame.

Acoil formed by wrapping 80 turns of wire in the shape of a square is positioned in a magnetic field so that the normal to the plane of the coil makes an angle of 28.0° with the direction of the field. when the magnetic field is increased uniformly from 200 µt to 600 µt in 0.400 as, an emf of magnitude 80.0 mv is induced in the coil. what is the total length of the wire?

The force acting on a beam was measured under the same operating conditions and a sample of 5 data points was collected. this process was repeated by 3 observers. the pooled standard deviations of these 3 data sets was 1.21. determine the true mean force using all pooled data (with a 95% probability). the result should look like this: true mean = mean +/- margin of error
