Speed= distance/time
Speed= 170/230
Speed=0.74 m/s
The car's speed is 240km/4hr= 60km/hr.
There's not enough information given in the question to determine its velocity.
Answer:
v = 10 m/s
Explanation:
Given that,
Distance covered by a sprinter, d = 100 m
Time taken by him to reach the finish line, t = 10 s
We need to find his average velocity. We know that velocity is equal to the distance covered divided by time taken. So,
v = d/t
Hence, his average velocity is 10 m/s.
Answer:
Inhibit the flow of electrons
Explanation:
An electric current usually consists of electrons moving through a wire.
An insulator prevents the flow of an electric current, so it inhibits the flow of electrons.
Answer:
Option (D) : The object slows down.
