Calculate the weight of air contained within a room 6 m long, 5 m wide, and 3 m high. assume standard pressure, 101 kpa, and temperature, 15 °c calculate the percentage change in total weight of air in the room when the temperature is reduced to -20 °c while the pressure remains the same.

the answer would be c. motion and direction

i hope this : )

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.

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.
