Aman is standing on a horizontal, nearly frictionless floor. he has suction cups on his shoes so he can walk and move around almost normally. in front of him is a crate with 100 times his mass. he exerts a steady horizontal force of 100 n on the crate and it accelerates across the floor at a constant acceleration; he runs forward with it to keep the force constant. what force does the crate exert on him?

When considering gravity acceleration and the force of acceleration, what must be true? a. the direction of acceleration must be perpendicular to the direction of the force. b. the direction of the force and the direction of acceleration must be the same as each other. c. the direction of the force and the direction of acceleration must be opposite of each other. d. the mass of the body must be the same as the acceleration of the body.

Chemical energy is a form of energy. a. heat b. kinetic c. potential d. electromagnetic

Ineed this now one scientist feels that the changes in global climatic patterns may be good for the health of the biosphere. another scientist feels that sharp changes in climatic patterns could result in the extinction of the biosphere. which of these is the most likely reason the two scientists gave conflicting opinions on the impact of changes in the global climatic pattern? they do not have enough knowledge on the topic. they did not discuss the issue among themselves. they believe conflicting opinion strengthens science. they study different areas of science and have different scientific focuses.
