Few qustions: 1.A point charge of 1,5 μC experiences an electric force of 0,08 N. What is the magnitude of electric field at that point.
2.Find the electric potential of a charge q=3x10–7 C, at distances away from its position of 18 cm in units of V. (Take k=9x109 Nm2/C2)
3.The points A and B are at distances away from a charge, q=10 μC of 2 cm and 1 cm, respectively. Find the potential difference between these points (Uab). (Take k=9x109 Nm2/C2)
4.A 100-W light bulb is connected to a 220-V source and operates for 4 hours. Find the current passing through the light bulb.

Hen a gfci receptacle device is installed on a 20-ampere branch circuit (12 awg copper), what is the minimum volume allowance (in cubic inches) required for conductor fill for each conductor in the outlet box?

In the first law of thermodynamics, triangle e=q-w, what does q stand for

Arunner is jogging at a steady 3.6 km/hr. when the runner is 2.9 km from the finish line, a bird begins flying from the runner to the finish line at 14.4 km/hr (4 times as fast as the runner). when the bird reaches the finish line, it turns around and flies back to the runner. even though the bird is a dodo, we will assume that it occupies only one point in space, i.e., a zero-length bird. how far does the bird travel? (b) after this first encounter, the bird then turns around and flies from the runner back to the finish line, turns around again and flies back to the runner. the bird repeats the back and forth trips until the runner reaches the finish line. how far does the bird travel from the beginning? (i.e. include the distance traveled to the first encounter)
