In a thundercloud there may be electric charges of 45.0 C near the top of the cloud and -45.0 C near the bottom of the cloud. Th

Gala2k [10]

Answer:

The electric force on the top charge is $F=3.44\times 10^6\ N$ .

Explanation:

Given that,

Electric charges in a thundercloud, $q_1=q_2=45\ C$

The distance between charges, d = 2.3 km = 2300 m

Let F is the electric force on the top charge. The electric force is given by the formula as :

$F=\dfrac{kq^2}{d^2}$

$F=\dfrac{9\times 10^9\times (45)^2}{(2300)^2}$

$F=3445179.58\ N$

$F=3.44\times 10^6\ N$

So, the electric force on the top charge is $F=3.44\times 10^6\ N$ . Hence, this is the required solution.

Answer:

Well this would be science... not physics...

Explanation:

1) both are a product of cooling lava/magma

2) Both stones can be caused during volcanic eruptions or clastic flow

3) Both are igneous in family (duh)

4) Intrusive rocks are formed underground from seeping into crevasses and are slow cooling and extrusive rocks are fast or instant cooling and cool above the surface (if differences are needed)
