Answer:
d = 2083.33 m
Explanation:
Given that,
Acceleration of the train, a = 0.15 m/s²
The initial speed of the car, u = 0\
Final velocity, v = 25 m/s
We need to find the minimum distance covered by the train. Let it is d. Using third equation of kinematics as follows :
So, the minimum distance is 2083.33 m
To answer your question, no,
temperature does not always increase as it is heated. Adding heat does not always increase the temp.
For example, when water is boiling, adding heat does not increase the temperature. This occurs at the boiling temp of every substance that can vaporize.
Hope this explanation was helpful and brief! :)
Answer:
Explanation:
As the truck is moving towards right and there is no friction between the truck and dog, it experiences a psheudo force, so the dog moves towards left.
Option (D)
Answer:
Explanation:
The initial velocity, u, of the car=15m/s
The final velocity, v, of the car =0m/s
Time, t, taken for the car to come to a stop=5s
Acceleration is calculated by,
By substitution,
The negative sign implies that the car has decelerated.
