Bill is an observer on earth. debra pilots a spaceship which passes earth at speed 0.820c in the +x direction. amanda pilots a spaceship which passes earth at speed 0.778c in the -y direction. bill holds a picture frame which lies in the x-y plane that is 0.75 m long (along x-direction) by 0.50 m wide (along y-direction). (a) what is the area of the picture frame as measured by debra? (b) what is the area of the picture frame as measured by amanda?

Answerthe energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.explanationwe define electric potential as the ratio electric potential energy to the charge,    then the following gives us the potential difference,      the formula  may be on your formula sheet.the change in electric potential energy would be the energy that would needed to move it from point a to point b. solving for that, we get    using q = 8.00  × 10⁻¹⁹ c and  δv = 2.00 v, we get    the energy required is 1.60 × 10⁻¹⁸ j, to three significant figures.

The independent variable in this experiment is the angle at which the light from the ray box strikes the mirror.hope this .
