Answer:
The speed of her at the bottom is 24.035 m/s.
Explanation:
Given that,
Speed of cyclist = 12 m/s
Height = 30 m
Distance d = 450 m
Mass of cyclist and bicycle =70 kg
Drag force = 12 N
We need to calculate the speed at the bottom
Using conservation of energy
K.E+P.E=drag force+K.E+P.E
Potential energy is zero at the bottom.
K.E+P.E=drag force+K.E
Hence, The speed of her at the bottom is 24.035 m/s.
To determine the amount of electrons in a given charge we need to remember that the charge of an electros is:
coulombs.
Now, if we have a given amount of charge an we want to know how many electrons are in the charge we divide it by the charge in the electron. In this case we have:
Therefore we have:
We know that for each step the worker collects -50nC, this is the same as collecting:
electrons. Now, that we know this we divide the maximum amount of charge the component can take by the electrons in each step:
Threfore the worker can take 3 complete steps before touching the component
Answer:
There were many examples of this. One of the most well-known not reversible reaction is a precipitation reaction, in which an insoluble solid is formed from two aqueous solutions. An example is the reaction between silver nitrate and sodium chloride which forms a silver chloride precipitate.
When an electric current is flowing through a wire, there is a magnetic <em>field</em> produced. The lines of magnetic force are circles around the wire.
