Answer:

For a 470-Ohm resistor connected to a 9-votl battery the current that will flow is 0.019A or 19mA

Explanation:

Ohm's law states that the voltage v along a resistor is directly proportional to the current i flowing through the resistor.

$v = i R$

Clear i from the equation above

$i = \frac{v}{R}$

$i = \frac{9volt}{470ohm} =0.019A$

Answer:

The elastic potential energy at point B is $PE_{elastic} = 50J$

The kinetic energy at point D is $KE = 75J$

Explanation:

Looking at the given point we can observe that mechanically energy(i.e potential and kinetic energy ) is conserved and it value is $E_ {m} = 100J$

So at point B

$E_{m} = PE_{elastic} +KE$

$100 = PE_{elastic} + KE$

KE at point B is 50J

So $PE_{elastic} = 100 - 50 = 50J$

Now at point D

$E_{m} = PE_{elastic} +KE$

$PE_{elastic}$ at point D is 25J

So $KE = 100 - 25 = 75J$

Probably the deadliest aspect of a thunderstorm is _____. rain thunder lightning hail

max2010maxim [7]

The answer to the given question is lightning.
Lightning is most probably the deadliest aspect of a thunderstorm. It is a sudden electrostatic discharge during an electrical storm. It happens when there is an electrostatic discharge between electrically charged regions of a cloud, which is referred as the intra-cloud lightning or IC, between that cloud and another cloud or the CC lightning, or between a cloud and the ground (CG lightning).
