Answer is
A contribute to the rising temperature of the planet
We have to speed up the watch so we need to decrease time period of pendulum. So we hv to reduce the length.
Answer:
True
Explanation: In pulley's , length of cables doesn't change.
Explanation:
Initial speed of the rocket, u = 0
Acceleration of the rocket,
Time taken, t = 3.39 s
Let v is the final velocity of the rocket when it runs out of fuels. Using the equation of kinematics as :
Let x is the initial position of the rocket. Using third equation of kinematics as :
Let is the position at the maximum height. Again using equation of motion as :
Now and v and u will interchange
x = 524.14 meters
Hence, this is the required solution.
