A small ball is hung by a string from the ceiling of a train car, so that the ball hangs vertically. Moving from rest, the train car accelerates forward, and continues to accelerate. A team of scientists observes the behavior of the ball from various locations. From which scientist's frame of reference does the motion of the ball appear to violate Newton's Law of Inertia?

c.is a substance that requires a small amount of energy per gram to raise its temperature; has strong cohesive forces between molecules.

explanation:

a colorless, transparent, odorless liquid that forms the seas, lakes, rivers, and rain and is the basis of the fluids of living organisms.

b.

hope this : )

the amount of current in the coil

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
