If the work required to speed a car from 10 km/h to 20 km/h is 5.0 x 103 J, what would be the work required to increase its speed from 20 km/h to 30 km/h.
In an experiment one finds that a force of 160 N produces a stretch of 8.00 cm in a
given spring. What is the spring constant of the spring?
. If the stress produced in stretching a wire is 5.00 x 10 6 N/m2 by an applied force of
10.0 N, what is the cross-sectional area of the wire?
An electronic field with a strength of 1.25×10⁴N/C exerted 2.50 Nnon a certain test charges, q. determine charge on q.
Calculate the electric field strength from a 1.25×10-8 C charge if the test charge is placed 2.50×10-5m.
Calculate the voltage of a battery connected to a parallel plate area of 2.00×10-2 m 2 and a plate separation of 2.0×10-³ m if the charge stored is 4.00×10-¹² C
