Absolute zero is not about numbers. It's about temperature, and the
motion of molecules in gases.
You know that the temperature we feel with our skin is the result of the
average speed of all the tiny molecules zipping around or vibrating in
the solid, liquid, or gas.
The faster they're all moving, the warmer the substance feels to us.
The slower they're all moving, the cooler the substance feels to us.
When molecules slow down to zero and lose all of their kinetic energy,
that temperature is what we call 'absolute zero' ... if they're not moving
at all, then they can't move any slower.
Answer:
T1 = 675 [N] ; T2 = 707.5 [N]
Explanation:
To solve this problem we must draw a free body diagram, where the bird is located, the posts and distances mentioned.
In the attached image we can see the free body diagram with different forces, angles and distances.
By conducting a distance analysis we can find the angles on both sides of the rope relative to the horizontal.
Then we perform a force analysis on the X-axis and the y-axis in order to find the two equations we need to find the stresses in the cables (T1 & T2)
It would fall at about/ around 96 mph
Answer:
B
Explanation:
B is the most likely region that contains alkaline earth family elements.
Atoms that emit particles and energy from their nuclei are (Radioactive).
