Answer:
v = 9.67 m/s
Explanation:
As we know that acceleration is rate of change in velocity
so it is defined as
here we know that
now we have
integrate both sides we have
here we know that
Answer:
The force is
Explanation:
Given that,
A long, straight wire carries a current.
Suppose, a long, straight wire carries a current 0.86 A. An electron is traveling in the vicinity of the wire. At the instant when the electron is 4.50 cm from the wire and traveling at speed of directly toward the wire. What are the magnitude of the force that the magnetic field of the current exerts on the electron?
We need to calculate the magnetic field
Using formula of magnetic field
Where, I = current
r = distance
Put the value into the formula
We need to calculate the force
Using formula of force
Here,
Where, q = charge of electron
v = velocity of electron
B = magnetic field
Put the value into the formula
Hence, The force is
It is an example of reactivity
iron usually rusts due to oxygen in the air
No correlation because it is neither positive or negative. The dots are scattered so that would be no correlation.
