A nozzle with a radius of 0.250 cm is attached to a garden hose with a radius of 0.700 cm. The velocity of the water in the hose is 1.90 m/s and the velocity of the water in the nozzle is 14.9 m/s Required:
a. Calculate the maximum height to which water could be squirted if it emerges from the nozzle.
b. Calculate the maximum height to which water could be squirted if it emerges with the nozzle removed, assuming the same flow rate.

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.

the aurora is formed when charged particles emitted from the sun during a solar flare penetrate the earth's magnetic shield and collide with atoms and molecules in our atmosphere. these collisions result in countless little bursts of light, called photons, which make up the aurora.

auroras are generated by charged solar particles hitting molecules in earth's atmosphere. this usually happens in high latitudes, because our planet’s magnetic field tends to funnel these particles toward the poles. that’s why it can be experienced in northern ohio.
