A cyclist covers the first part of her journey At a speed of 25m/s, and she took 50s to cover that part.
The second part of the journey was 900m.
Her average speed was 18m/s.
Calculate her speed in second part

Pls pls pls pls ! describe, in your own words, how you found the epicenter of the earthquake.

How does the strength of the electrostatic force between an electron and a proton compare to the strength of the gravitational force between them?

Adielectric-filled parallel-plate capacitor has plate area a = 30.0 cm2 , plate separation d = 9.00 mm and dielectric constant k = 3.00. the capacitor is connected to a battery that creates a constant voltage v = 15.0 v . throughout the problem, use ϵ0 = 8.85x10-12 c2/n.m2 . find the energy u1 of the dielectric-filled capacitor.
