To be safe during a lightning storm, it is best to be a. on a metal observation tower. b. inside a metal car. c. inside a wooden building without any grounding. d. in the middle of a grassy meadow. e. next to a tall tree in a forest.

Lightning and thunder occur when an electric field is generated between the cloud and the earth. When there are opposite charges, electricity travels through them and generates what we visually see as lightning and auditory we hear as thunder.

For the particular case of the meadow, there is not only direct conduction between the floor (which is full of water) and the sky, but also an individual is the only 'tall' object that can reach thunder more easily.

In the case of the tree, although it is taller, it is vulnerable to thunder falling there and it can fall on the person or be injured.

The tower is made of metal, which is a direct conductor of electricity that will expose the person in contact with it.

The wood construction might be ideal, but the floor could be damp, and remember that water is a conductor of electricity that could bring us electricity.

The car acts as an insulator for its tires and also serves as a capsule. It cuts the flow between heaven and earth which would allow it to serve as a good refuge.

Therefore the correct answer is B.

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.

as we probably am aware that our atmosphere or air have various levels, each level has different gasses, and each gas has another porousness. at the point when the light originates from lower porousness to higher penetrability, it alters its course. with the goal that implies that when the light originates from the moon to the earth, it alters it's course a lot more occasions. it essentially implies that the state of the light piece of the moon is changed on the earth.

not copied too! hope this !
