Atest charge of -1.4 × 10-7 coulombs experiences a force of 5.4 × 10-1 newtons. calculate the magnitude of the electric field created by the negative test charge.

a. 1.4 × 106 newtons/coulomb
b. 1.9 × 106 newtons/coulomb
c. 5.4 × 10-1 newtons/coulomb
d. 3.6 × 106 newtons/coulomb

D. 3.6*10^-6

Explanation:

Electric field strength E= Force on a charge / charge

E = F/q

E = 5.4*10^-1 / 1.4*10^-7

E = 3.857*10^6 N/C

the total distance traveled by the car is

30km + 49km = 79 km .

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
