Object 1 has a charge of -2.3 x 10^-6 and Object 2 has a charge of - 4.2 x 10 ^- 6 C. Calculate the electrostatic force between the two objects if they are 0.099 m apart. A) 9.76 x 10^-11 N
B) 9.86 x 10^-10 N
C) 8.87 N
D) 0.878 N

When seismic waves hit a fault, the waves are reflected off the fault. seismograph can detect these reflected seismic waves. geologists then use these data to map the fault's length and depth

All are great precautions but you can still lift lighter and different muscles in between hard workdays. this keeps other muscles not usually used in shape.

The boat's velocity relative to the riverbank can be resolved into two components. the component going north is 2.7 m/s and the component going west is 1.2 m/s.we add these two vectors and then find the magnitude of the resultant to get the speed.the magnitude of the resultant vector from adding can be obtained by the pythagorean theorem.    to two significant figures, the boat's speed relative to the riverbank is 3.0 m/s.

Dis the best answer im sure it is it has to be im positive
