B) Reset the app. Check the boxes that say "values" and "speed". Slide friction to maximum (notice the ground). Apply 50 N of force to the crate. Slowly click to increase the amount of
applied force until you reach 350 N of applied force. Describe how the force of friction changes
while you are increasing the applied force.
i. Describe how the force of friction changes while you are increasing the applied force.
ii. What was different about this compared to a?

Amachinist needs to remove a tight fitting pin of material a from a hole in a block made of material b. the machinist heats both the pin and the block to the same high temperature and removes the pin easily. what statement relates the coefficient of thermal expansion of material a to that of material b? a) the situation is not possible, heating block b will shrink the hole in the material as the material expands with increasing temperatureb) material b has the same coefficient of expansion as does material ac) material b has a negative coefficient of expansion and a has a positive coefficient of expansiond) material a has a greater coefficient of expansion than does material be) material b has a greate

Along, straight wire with 3.0 a current flowing through it produces magnetic field strength 1.0 t at its surface. if the wire has a radius r, where within the wire is the field strength equal to 36.0% of the field strength at the surface of the wire? assume that the current density is uniform throughout the wire

When many atoms are split in a chain reaction, a large explosion occurs. this is an example of what type of energy conservation
