It will take 20 seconds for the car to attain a speed of 34 m/s
Explanation:
- Acceleration of an object is given by a = velocity/time.
- Here, acceleration of the car = 1.7 m/s² and velocity = 34 m/s. Using these, find time.
- Time = velocity/acceleration
= 34/1.7 = 20 s
So it takes 20 seconds to attain a speed of 34 m/s
Answer:
D
Explanation:
We must never use a piece of pipe as a leverage extension on the handle on a wrench.
Hence option d is correct.
The atoms vibrate faster and the space between atoms spread
Explanation:
Speed = Distance/Time
15cm/s = (500×100)cm/ time
time = 50000/15
time = 3333.33 s
time = 55.6min
Answer:
55.6 min
