A point in the electric field of two different charged particles is 300 cm from the negatively charged particle, and 600 cm from the positively charged particle. The charge of the positive charge is 6 nC, the charge of the negative charge is -3 nC. What is the strength of the electric field at the point of measurement? * 1 point
-1.5 N/C
-5.2425 N/C
-1.49 X 10^-4 N/C
1.5 N/C

Two friends are having a conversation. anna says a satellite in orbit is in freefall because the satellite keeps falling toward earth. tom says a satellite in orbit is not in freefall because the acceleration due to gravity is not 9.80 m/2 . who do you agree with and why?

Infrared radiation has wavelengths that are shorter than visible light is part of the visible light spectrum has wavelengths that are longer than visible light has the same wavelengths as ultraviolet radiation

Why is rain likely when warm, moisture-laden air meets cold air? a) the lighter warm air will rise and cool down, causing condensation and rain. b) the cold air moves faster and pushes the warm air away, causing condensation and rain. c) the moisture in the warm air condenses on contact with the cold air, causing rain to fall. d) the cold air mixes with the warm air, reducing its temperature causing moisture to condense.
