Two charges are located on the positive − of a coordinate system. Charge 1 = 2 × 10 -9 C is 2 from the origin, and charge 2 = 3 × 10 -9 4 from the origin. What is the magnitude of the total force exerted by these two charges on a charge 3 = 5 × 10-9 located at the origin?

answer: 2×10^-2kg

explanation: density= mass per volume

vol=mass/density

converting to s.i units we have;

3÷1000kg = 0.003

1.5÷100m = 0.15

0.003/0.15 = 0.02kg

a 2,000 calorie based diet.

the answer is false. this is because for ice to melt, it requires latent heat of melting. latent heat means heat energy required to change phase without any increase in temperatures. therefore, the ice will take energy from the environment to melt hence atmospheric temperatures will reduce.
