Pls help :(( I need help!! Its physics! motion and forces!
Delvig [45]

Answer: Pedaling your bike : acceleration :: applying the brakes : inertia.

The reason I think this to be the answer to the analogy is because there is energy and work used in both processes (and the unit focuses on forces); gravity is constant and does not change whether one pedals or applies brakes. And I do not think it's deceleration, as deceleration tends to equate to acceleration within the physics perspective.

Edit: I should also add that since you clarified that your unit is motion and forces, Newtons 1st law is the law of inertia. The way to change an objects motion for it to slow down is by applying an additional force. That resistance the bike experiences to slow is the process of inertia. Inertia happens in order to accelerate an object (either by slowing it down, or speeding it up): i.e., the resistance to change.

Find the net charge of a system consisting of 206 electrons and 161 protons. Express your answer using two significant figures.
kondaur [170]

Answer:

-72\times 10^{-19}C[/tex]

Explanation:

Both electron and proton have the same amount of charge but signs are opposite , electron contains negative charge and proton contain positive charge

Charge on 1 electron = -1.6\times 10^{-19}C

So charge on 206 electron =-206\times 1.6\times 10^{-19}C

Charge on 1 proton = -1.6\times 10^{-19}C

So charge on 161 electron =-106\times 1.6\times 10^{-19}C

So charge of the system = (-206+161)\times 1.6\times 10^{-19}C

=-72\times 10^{-19}C
