A triangle with equal sides of length 1.0 x 103 m has -2.0 C charged objects at each corner. Determine the electrical force (magnitude and direction) exerted on the object at the top corner due to the two objects at the base of the triangle.

Determine the age of a fossil if it had only one eighth of its original carbon-14 content remaining?

If angle "a" is 25°, angle "b" is: a) equal to angle c b) less than angle c c) greater than angle c

A55-kg pilot flies a jet trainer in a half vertical loop of 1200-m radius so that the speed of the trainer decreases at a constant rate. knowing that the plane has a speed of 550 km/h at point a, and the pilot experiences weightlessness at point c (i. e., the normal force from the seat bottom is zero), determine (a) the deceleration of the plane, (b) the force exerted on her by the seat of the trainer when the trainer is at point b.
