Answer:
b
Explanation:
it compresses hot air turning into cool air almost like a reverse tornado
The answer of speed is 4.5m/s
Answer:
W = 85.73 m
Explanation:
given,
surveyor walks = 118 m
makes an angle of = 36.0° with the tree
to find the width of the river
W = 85.73 m
hence, the width of the river is equal to W = 85.73 m
Answer:
In a nutshell, a scientific law predicts what happens while other laws devised by people usually proposes why certain things happen.
Explanation:
A scientific law is one that predicts the results of certain initial conditions. In order words, it predicts what will happen when certain conditions are fulfilled. A very good example is Newton's 3 laws of motion where like the third law which says to every action, there is an equal and opposite reaction or like in the first law which says a body at rest will remain at rest unless it is acted upon by an external force.
Whereas, other laws devised by people usually provides the most logical explanation as to why things happen the way they do. For example explaining why some children develop certain peculiar health issues when they are newly born.

Inertia increases as mass increases.
Explanation:
Inertia is the resistance of an object to any change in motion. Inertia is proportional the mass of the object: in fact, as we experience in common situations, the larger the mass of an object, the more difficult it is to change its motion.
A simple example: while it is quite easy to stop a tennis ball thrown towards us, we know that it is not so easy to stop a large truck travelling towards us with the same speed: the reason for that is that the truck has much more mass than the tennis ball, so it has much more inertia. Therefore, inertia increases as mass increases.
