Hope this helps! ;)
Answer:
Option C
A feather falls from one end of a tube to the other inside a vacuum
Explanation:
In conservative force field, which in this case is a vacuum, you expect that there will be no loss of energy to air-friction. Therefore, when a feather falls from one end of the tube to the other side which is a vacuum, we expect no energy loss. Conservative forces are the forces that are path-independent. This implies that in a closed loop, the total work done is zero. Considering the options given, only feather falls from one end of a tube to the other inside a vacuum meets the criteria
Answer:
40 J
Explanation:
In the case of a rectilinear movement, the work is calculated as the product of Force (N) * movement (m). In your case, unless the angle between the force vector and the displacement vector is different from 0, the work is:
20 N * 2 m = 40 J
Answer:
anything that contains atoms is the correct answer of given statement
Answer:
Ek= 35.392 kJ or 35.392 10³ J
Explanation:
Formula for Kinetic energy:
Ek= × m ×
since m= 65kg and v= 33m/s
Ek= × 65×
Ek= 35.392 kJ or 35.392 10³ J
