Answer:
2.7%
Explanation:
Given:
Uncertainty of the speedometer (u)= 2.5km/h
Speed measured at that uncertainty (v) = 92km/h
Percent uncertainty (p) is given as the ratio of the uncertainty to the speed measured then multiplied by 100%. i.e
p = %
p = %
p = 2.7%
Therefore, the percent uncertainty is 2.7%
Answer:
this force is times more than the gravitational force
Explanation:
Kinetic Energy of the electron is given as
now the speed of electron is given as
now we have
now the maximum force due to magnetic field is given as
Now if this force is compared by the gravitational force on the electron then it is
so this force is times more than the gravitational force
