Two particles are separated by 0.38 m and have charges of -6.25 x 10-°C and 2.91 x 10-9 C. Use Coulomb's law to predict the force between the
particles if the distance is doubled. The equation for Coulomb's law is
F = kq92, and the constant, k, equals 9.00 x 109 Nm2/C2

Aspring with a mass of 2 kg has a damping constant 14 kg/s. a force of 3.6 n is required to keep the spring stretched 0.3 m beyond its natural length. the spring is stretched 0.6 m beyond its natural length and then released. find the position of the mass at any time t. (assume that movement to the right is the positive x-direction and the spring is attached to a wall at the left end.)

Pls ! what are 3 examples of acceleration that doesn’t involve a change in speed ?

When and why was the metric system invented?
