Answer: meteorology </h2>
Explanation:
From the given options , meteorology is the only one that can be studied objectively, since it is an interdisciplinary science that relies on basic sciences such as physics and mathematics and applied sciences to the study of the atmosphere, the weather, the phenomena produced and the physical laws that govern it. In addition, meteorology uses objective techniques to study and predict the various phenomena that occur in the atmosphere.
Unlike history, sociology and theology, in which there is a possibility of the existence of some data are subjective and not true or only based on opinions <u>without scientific evidence</u>.
Answer:
8.33 m/s, 36.87° North of East
Explanation:
= Mass of car = 1000 kg
= Velocity of car = 15 m/s
= Mass of truck = 2000 kg
= Velocity of truck = 10 m/s
M = Combined mass = 1000+2000 = 3000 kg
Momentum
Momentum of car traveling East is 15000 kgm/s
Momentum of truck traveling North is 20000 kgm/s
Angle
As the two vehicles are vectors, the resultant velocity is
Velocity of the two vehicles when they are locked together is 8.33 m/s and direction is 36.87° North of East
