You are conducting an experiment inside a train car that may move along level rail tracks. A load is hung from the ceiling on a string The load is not swinging. and the string is observed to make a constant angle of 45 degree with the horizontal. No other forces are acting on the load. Which of the following statements are correct?
A) The train is an inertial frame of reference
B) The train is not an inertial frame of reference
C) The train may be instantaneously at rest
D) The train may be moving at a constant speed in a straight line
E) The train may be moving at a constant speed in a circle
F) The train must be speeding up

A3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular? a 3030 cmcm wrench is used to loosen a bolt with a force applied 0.30.3 mm from the bolt. it takes 6060 nn to loosen the bolt when the force is applied perpendicular to the wrench. how much force would it take if the force was applied at a 3030 degree angle from perpendicular?
