Asteel tank is to be positioned in an excavation. determine the requiredmagnitude of force p if the resultant of the two forces applied at a is to be vertical. what is the magnitude of the resultant force?

ill do it for 100, also this isnt 80 its 40

the results is a decrease in air temperature with an increase of altitude.

explanation:

scientific laws are the result of testing theories and proving them to be facts.

see the picture for the vector

the magnitude of the vector by pythagorean theorem

r = √( (-10)^2 + (3)^2 ) = √109

magnitude = √109 units

the direction angle between vector and x-axis is

tan^(-1)(3/10) = 16.699

so the direction is approximately 16.7 degrees north of west
