Answer:
r=15.53 nm
Explanation:
Lets take electron is in between iron and uranium
Charge on electron
Charge on iron
Charge on uranium
We know that force between two charge
For equilibrium force between electron and iron should be force between electron and uranium
Lets take distance between electron and uranium is r so distance between electron and iron will be 37.5-r nm
Now by balancing the force
So r=15.53 nm
So force
Answer:
It traveled 4 centimeters.
Explanation:
In a speed versus time graph, the distance travelled is given by the area under the graph.
In this graph we have the following:
- The speed of the object is v = 1 cm/s between time t = 0 s and t = 4 s
- The speed of the object is v = 0 cm/s between time t = 4 s and t = 8 s
Since the speed in the second part is zero, the distance travelled in the second part is zero. So, the only distance travelled by the object is the distance travelled during the first part, which is equal to the area of the first rectangle:
