The wind in Toledo gusts up to a sustained speed of 20 m/s. Assuming the air density of 1.29 kg/m3, calculate the total force exerted on a flat roof having an area of 100 m2.

when the use of electricity burdens the fuse and miniarure circuit beakers and there is a possibility of a fuse then they automatically cut off the electricity supply to your homes and after you fix the problem u jzt switch it on and it continues the supply of electricity to ur homes

i need the answer to this too but idk it ; -;

r = ρ x length / area  

ρ = r x area / length  

ρ is in ohm-meters  

in basic units, it is m³kg/s³a²  

i think this is it.
