Answer:
R / 25
Explanation:
Let the initial length of the wire is L and its resistance is R.
Now the length is cut into 5 equal parts.
The resistance of a wire is directly proportional to the length of the wire, thus, the resistance of each portion of the wire is R/5.
Now the five pieces are connected in parallel combination, the equivalent resistance is
Thus, the resistance of the new cable is R / 25.
Answer:
a. 0.01 C
b. dissipated to outside environment
Explanation:
Let the specific heat of copper be 0.3846 kJ/kg-K or 384.6 J/kg-C
(a)The original kinetic energy of the block is:
As 85% of this kinetic energy is converted to block internal heat energy, with specific heat we can calculate the rise in temperature:
(b) the remaining 15% energy would probably be dissipated to outside environment as heat energy
