Which of the following is something you should do during severe weather?

stay in doors and away from the windows

Explanation:

During a thunderstorm, you should remain indoors and have a weather radio handy. Your family should be prepared for the possibility of high winds and power failures. Have candles, emergency supplies, food, and water accessible. Some thunderstorms have been known to cause power failures for millions of people at a time. During a severe weather event, the National Weather Service will issue watches and warnings associated with the storm system. A watch means that severe weather may be possible in the near future. You should take precautions during a watch. A warning is issued when severe weather is likely to strike at any moment. All watches and warnings for severe weather should be listened to carefully.

the minimum constant speed at which she can catch the train is 2.7 m/s

given:

acceleration = 0.6

time = 4.5 s

to find:

velocity = ?

formula used:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

solution:

from 1st kinematic equation we get,

v = u + at

u = initial speed of train = 0 m/s

v = final speed of the train

a = acceleration of the train

t = time

v = 0 + (0.6 × 4.5)

v = 2.7 m/s

the minimum constant speed at which she can catch the train is 2.7 m/s

causes

fossil fuels burn

cities become more industrialized

human population grows worldwide
