A fireman is directing water at the rate of 16 kg/s onto a burning building. The speed of the water within the horizontal hose nis 3.0m/s. However, because of the tapered shape of the nozzle, the speed at which
leaves the hose is 11.0 m/s. To keep the hose moving because of the thrust of the water, the fireman must
apply a force to the hose. How much force must the fireman apply?

not moving. pos accel,

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.
