Answer:
In case of electrostatic force, the work done is independent of path, it only depends on the final and initial positions of the charge. This path independent nature makes electrostatic force a conservative force. Thus, the option a becomes true, and the opposite statement (ie.
Answer:
True
False
False
Explanation:
4.True, When a positively charged object is connect to the 'ground' electrons flow from the 'ground' wire to neutralize the object.
5. False, Electrons can be influenced to move a specific way, but are free to move from atom to atom.
6. False, only electrons move from one object to another.
There are two ways to find energy. Energy=F*d=mv^2. We can use this relationship to find v:
Answer:
2666 kg
0.11567 m/s²
Explanation:
m = Mass of boat
a = Acceleration of boat
From Newton's second law
Force
Force on the first boat is 333.25 N
Hence, mass of the second boat is 2666 kg
Combined mass = 2666+215 = 2881 kg
The acceleration on the combined mass is 0.11567 m/s²
