Your fine will be based on your instantaneous speed.
<h3>How can we know that the fine will be based on your instantaneous speed or average speed?</h3>
According to the definition,
- Instantaneous velocity is the magnitude (speed) and direction of an object at any instance during travel.
- Average velocity is total displacement divided by total time (Note: displacement is measured from starting point to ending point in a straight line).
- And also, instantaneous speed is the speed that one can capture by the radar gun at the exact moment.
- The traffic police can not define your average speed because they does not know where you start your journey, neither they know your destination.
- So, they can not fine you with your average speed.
- They can find your instantaneous speed by their radar gun.
From the above discussion we can tell that, Your fine will be based on your instantaneous speed.

Answer:
Explanation:
In the process of convection, first the molecules of substance gets heat and becomes heated. As the molecules heated, their density decreases and hence they rises up. And the molecules which are cooler, they fall and comes in contact of higher temperature and then they rises up. the process repeats itself until the entire liquid heated uniformly.
Answer:
the tension in the cable= 929.33N
Explanation:
the tension in the cable is equivalent to the frictional force experienced between the road and the stunt man
coefficient of friction= μ=
μ=0.870
N= Normal force =m × g
m= 109kg
g= acceleration due to gravity =9.8m/s²
= μ × N
= μ × m × g
= 0.870 × 109 × 9.8
=929.33N
The tension in the cable is 929.33N
Answer:
Explanation:
Force on a current carrying rod due to magnetic field is given as
here we know that
current in the rod
now magnetic force is balanced by the weight of the rod
so we will have
Explanation:
F = mv²/r
If the velocity is halved:
F' = m(v/2)²/r
F' = ¼ mv²/r
F' = ¼ F
The centripetal force is reduced by a factor of 4.
