Answer:
(D) 30.6 cm
Explanation:
Given the following data;
Measurement A = 18.425 cm
Measurement B = 7.21 cm
Measurement C = 5.0 cm.
To find the total measurement;
Total measurement = A + B + C
Total measurement = 18.425 + 7.21 + 5
Total measurement = 30.635 cm
However, an additional sum requires that all the numbers have a equal number of decimal points; 1 decimal point for 5.0 would be chosen.
Hence, we would round up the answer to 1 decimal point.
Total measurement = 30.6 cm
Answer: Friction
Explanation:
Friction and the normal force would be the two initial forces to overcome.
Answer:
a. 2.856 x 10^-6 m³
b. 0.288 J
c. 971.88 J
d. 971.592 J
Explanation:
d) The change in internal energy of the cube.
Note: For Copper -
B(beta)= 5.1 × 10^-3 (C)^-1
Cp = 390J/Kg.K
p (Rho) = 8.90 × 10³Kg/m³
Detailed solution is attached below
Because after each impact it loses a fraction of its original energy, because it gets transfered to the floor. this is the reason that a perpetual motion machine is impossible. you cannot have infinite energy, because to perform a task, energy must be spent. hope i helped :3
