A train departs from its station at a constant acceleration of 5 m/s. What is the speed of the train at the end of 20s?
2 answers:
Answer:
Velocity, v = 100 m/s
Explanation:
It is given that,
Initial speed of the train, u = 0
Acceleration of the train,
Let v is the velocity of the train at the end of 20 seconds, t = 20 s
Using the equation of kinematics as :
v = u + a × t
v = a × t
v = 5 × 20
v = 100 m/s
So, the velocity of the train after 20 s is 100 meters. Hence, this is the required solution.

1) First of all, let's find the resistance of the wire by using Ohm's law:
where V is the potential difference applied on the wire, I the current and R the resistance. For the resistor in the problem we have:
2) Now that we have the value of the resistance, we can find the resistivity of the wire
by using the following relationship:
Where A is the cross-sectional area of the wire and L its length.
We already have its length
, while we need to calculate the area A starting from the radius:
And now we can find the resistivity:
