Calculate the plume rise from a 0.5 meter diameter smokestack emitting 5 m3/s of air at 500 degrees celsius. data from a nearby meteorologic station indicates the average wind speed in the area is 5 m/s, the environemntal temperature at the height of the stack is 280 degrees celsius and the potential temperature gradient is -0.01 degrees/m.

answer with explanation:

when dealing with heavy loads, one needs to take certain precautions in order to avoid or prevent from injuries.

for instance, one should avoid lifting above the shoulder level which can end up pulling your muscle.

also, you can either break the load in parts if possible or get some for lifting heavy bulks.

moreover, one should try to lift with the legs while keeping the back straight and not twisting it.

answer & explanation:

"the force on a cutting tool are 2600n vertically downward" sounds a little unusual, since most of the time, the tool is above the object to be cut in such a way that the force acting "on the tool" is upwards.   we will accept the statement as it is (downwards).

since the two forces are acting at right angles to each other, the resultant can be found using pythagoras theorem, namely

resultant = sqrt(2600^2+2100^2) = 3342 n (approx.)

the angle can be found using the arctangent function, or

angle = arctangent(2600/2100) = 51.07 degrees below the horizontal, since the 2600 n force is acting downwards.
