Describe how a chronological record of Earth’s atmosphere for the past 420 000 years can be constructed from ice-core samples.

the answer is 46 mls because when you add the speed per second it increses the speed

c. newton's third law of motion

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
