A charge of 40 µC is pushed by a force of 15 µN a distance of 1.3 mm in an electric field.

What is the electric potential difference?

2.0 × 10-8 V
4.6 × 10-7 V
4.9 × 10-4 V
3.8 × 10-1 V

The uniform slender bar rests on a smooth horizon- tal surface when a force f is applied normal to the bar at point a. point a is observed to have an initial acceleration aa of 20 m/s2, and the bar has a corre- sponding angular acceleration of 18 rad /s2. deter- mine the distance b.

The law of reflection states that the angle of reflection is equal to the angle of

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
