Answer:
Explanation:
Suppose the tension in the ribbon is T.
The upwards component of the tension = Tcos13
The horizontal component of the tension = Tsin13
The weight of the medal = mg
In a vertical direction, mg is balanced by Tcos13, so mg=Tcos13, so T = mg/cos13. The horizontal component of T is the force causing m to accelerate.
Substituting T= mg/cos13 gives:
cancels and you have
exothermic
Explanation:
negative means it's losing energy
Answer:
If a vertical line extending down from an object's CG extends outside its area of support, the object will topple
Explanation:
We can understand better this situation using a diagram with the forces acting on it.
In the attached image we can see that when the gravity center is bouncing outside from the area of the pedestal, the object will be out of balance and will fall.
Answer: C. Electron degeneracy pressure depends on the speeds of electrons, which approach the speed of light as a white dwarf's mass approaches the 1.4-solar-mass limit.
