Answer:
see below
Explanation:
First: Leave a couple inches of wire loose at one end and wrap most of the rest of the wire around iron u-shaped bar and make sure not to overlap the wires.
Second:Cut the wire (if needed) so that there is about a couple inches loose at the other end too.
Third: Now remove about an inch of the plastic coating from both ends of the wire and connect the one wire to one end of a battery and the other wire to the other end of the battery.
Answer:
When the average kinetic energy of its particles increases, the object's thermal energy increases. Therefore, the thermal energy of an object increases as its temperature increases.
Answer:
Explanation:
Given the absence of non-conservative force, the motion of the coin is modelled after the Principle of Energy Conservation solely.
The moment of inertia of the coin is:
After some algebraic handling, an expression for the maximum vertical height is derived:
Answer: 4.74 mm
Explanation:
We can solve this problem with the following equation:
(1)
Where:
is the Young modulus for femur
is the stress (force 
applied per unit of transversal area 
) on the femur
Being:
the compression the femur can withstand before breaking
is the length of the femur without compression
Writing the data in equation (1):
(2)
(3)
Isolating :
(4)
(5) This is the compression in meters
Converting this result to millimeters:
