Acharge q produces an electric field of strength 4e at a distance of d away. determine the electric field strength at a distance of d away.

a.) e

b.) e

c.) 36e

d.) 9e

c.) 36E

Explanation:

The magnitude of the electric field is given by the expression

(1)

where k is the Coulomb's constant, q is the charge that generates the field, and d is the distance from the charge.

In this problem, we have that the magnitude of the field at a distance d is 4E, so we can rewrite the previous equation as

Now we want to determine the electric field at a distance of away. Substituting into (1), we find

(2)

We also know that

(3)

So combining (2) with (3), we find a relationship between the original field and the new field:

answer: the correct answer is   air pressure at the top of mount everest is higher than at the bottom of the grand canyon.

hope this : )

explanation:

answer: 802.3 kilo joules of energy represents 191.75 kilo calorie of energy.

explanation:

energy released during combustion of one mole methane = 802.3 kilo joules

if 1 kilo joule = 0.239006   kilo calorie

then ,802.3 kilo joule will be = 802.30.239006 kilo calorie

802.3 kilo joule = 191.75 kilo calorie

hence, the energy in kilo calorie is 191.75 kilo calorie.
