Answer:
B. The particles that make up material B have more mass than the
particles that make up material A.
Explanation:
Forces are vector quantities and we can add them as such. Because both the weight of the person is 450 N and the weight of the bag pack is 45 N, both of those forces act in the same direction and we simply add our weight and the weight of the bag pack:
450 N + 45 N = 495 N.
So the net force that acts on the ground is 495 N.
The phase and amplitude of rhythms in physiology and behavior are generated by circadian oscillators and entrained to the 24 h day by exposure to the light and dark cycle and feedback from the sleep wake cycle.the extent to which the phase and amplitude of multiple rhythms are similarly affected during altered timing of light exposure and the sleep wake cycle has not been fully characterized.
Solid, because the atoms maintain their form and do not take the shape of their container. The particles share tight, close bonds due to this set shape
Hope this helps. If you need clarification just ask me!
