After rubbing the head, ballon get all the electrones and negatively charged and hair get positively charged, then their is electro static force between hair and ballon
If there is air, then an object with greater mass falls toward Earth at a greater acceleration because it encounters less air resistance than if it had a smaller mass. There is no air resistance if there is no air, so they'll fall at the same acceleration.
Answer:
The final velocity of the fisherman and the boat = -1.27 m/s
Explanation:
Mass of fisherman, M₁ = 81 kg
Mas of Rowboat, M₂ = 136 kg
Initial velocity of the fisherman, v₁ = -3.4 m/s (Westwards)
Initial velocity of the rowboat, v₂ = 0 m/s ( It is at rest)
The final velocity of the fisherman and the boat, v = ?
Using the principle of momentum conservation
M₁v₁ + M₂v₂ = (M₁ + M₂) v
-(81*3.4) + (136*0) = (81 + 136) v
-275.4 = 217v
v = -275.4/217
v = -1.27 m/s
Answer:
The answer is point C because as the planet gets closer to the edge, then it starts to accelerate.
Explanation:
Electrons are found in shells or orbitals that surround the nucleus of an atom
