To solve this problem it is necessary to apply the concepts related to thermal linear expansion. Mathematically this concept can be expressed under the Equation:
Where,
Initial Length
Thermal Expanssion constant
Change in Lenght
Our values are given as
Replacing at our equation we have,
Therefore the expantion of the bar is 0.317mm
The normal force is equal in magnitude and opposite in direction to the weight of the student.
W = m · g = 60 kg · 10 m/s² = 600 N ( downward )
N = - 600 N
Answer:
B ) 600 N upward.
B
The Ardi fossil is believed to be 4.4 million years old, providing evidence that humans have been on Earth for 4 million years.
There's no physics or electronics to this question.
It's just arithmetic.
The last part of the question TELLS you how many 'coulombs per electron'.
If you just flip that fraction (divide ' 1 ' by it, take its reciprocal), then
you'll have 'electrons per coulomb', and 5 of those will answer the question.
I got 31,250,000,000,000,000,000 . I could be wrong. You should check it.
