Answer:
63N, 45N
Explanation:
Given:
Tension 1 = T1
We have the following free body equations:
F - T1 = 100*0.3 -(I)
T1 - T2 = 60*0.3 -(II)
T2 = 150*0.3 -(III)
Adding the three above equations, we have
F - T1 + T1 - T2 + T2 = (100*0.3) + (60*0.3) + (150*0.3)
Hence, F = 93N
Hence, substituting into equation I we have
T1 = Force by bar on lighter cart = 93 - (100*0.3) = 63N
Hence, force that heavier cart exerts on bar
T2 = 150*0.3 = 45N
Answer:
B
Explanation:
if you want to change an object's momentum you need to apply force to the object
Answer:
With distance from the ridge crest, the sediments and crust get thicker. This also supports the idea that the youngest rocks are on the ridge axis and that the rocks get older with distance away from the ridge (Figure below). Something causes the seafloor to be created at the ridge crest.
Answer:
True
Explanation:
No matter what it is, even photons, they still have a force acting upon them whether it affects them or not.
