<span>Once the presence of certain substances in a sample is known, the study of their absolute or relative abundance can help in determining specific properties. Gravimetric analysis yields more accurate data about the composition of a sample than volumetric analysis but also takes more time to perform in the laboratory.</span>
The major winds for the cities that are located at latitudes of 35 degrees north are prevailing winds and westerlies. Prevailing winds are winds that blow in a single direction. Westerlies are prevailing winds that blow towards the west side of the Earth.
The correct answer is rock cycle
Centripetal acceleration ac is the acceleration experienced while in uniform circular motion. It always points toward the center of rotation. It is perpendicular to the linear velocity (tangential speed) v and has the magnitude:
Solving for v:
If the coefficient of static friction is 0.15, then 0.15 of the crate's weight
shows up as a force resisting the horizontal pull. So we really only
need to know the crate's weight.
Weight = (mass) x (gravity) = (25) x (9.8) = 245 newtons.
0.15 of 245 newtons = <u>36.75 newtons</u>.
The force due to friction that's holding the crate back, not letting it start
sliding, is 36.75 newtons. If you push it with 75 newtons of force, then
that <em> IS</em> enough to make the crate accelerate.
