The technique that used to measure the distance

Answer to Problem 1VSC
Solution:
Cepheid variable stars technique is used to measure a distance of
Explanation of Solution
Introduction:
An effective technique is used to measure a large distance between astronomical objects.
Cepheid variables stars are extremely luminous and can be observed and measured at a large distance. There is a definite relation between the period and luminosity of Cepheid variables. With the help of period-luminosity relation to large distance such as between galaxies can be found.
Conclusion:
Cepheid variables stars

The 3.7 × 10-10 C sphere is fixed whie the 3.0 × 107 C sphere, initially at rest, is free to move. The mass of each sphere is 0.09 kg. If the spheres are initially 0.10 m apart, how fast will the sphere be moving when they are 1.5 m apart?arrow_forwardpls help on allarrow_forward
