calculate the electric field in the fourth vertex of the rectangle if Q1 = 2x10-8 C (+) Q2 = 106 C (+) and Q3 = 3x10-8 C (-)

Aplane flies directly between two cities, a and b, which are separated by . from a to b, the plane flies into a headwind. on the return trip from b to a, the wind velocity is unchanged. the trip from b to a takes less than the trip from a to b. what is the airspeed of the plane, assuming it is the same in both directions

Isla’s change in velocity is 30 m/s, and hazel has the same change in velocity. which best explains why they would have different accelerations? isla had negative acceleration, and hazel had positive. isla had a different time than hazel. isla had positive acceleration, and hazel had negative. isla went a farther distance than hazel.

What is the weight of a feather (mass = 0.0001 kg) that floats through earth's and the moon's atmospheres?
