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.
Electricity which may efficient transportation if you develop your way depending contact metal basis , such as electric train .
-Water is from of heat-energy using solar power which run a turbine may be wheel on a railway path.
Answer:
The frequency of the wheel is the number of revolutions per second:
f= \frac{N_{rev}}{t}= \frac{10}{1 s}=10 Hz
And now we can calculate the angular speed, which is given by:
\omega = 2 \pi f=2 \pi (10 Hz)=62.8 rad/s in the clockwise direction.
Explanation:
The activation energy is lowered only
There are more collisions per second and the collisions are of greater energy
There are more collisions per second only
The activation energy is lowered
Answer:
Explanation:
The linear charge density id defined as the charge per unit length.
Let q be the charge and L be the length of the wire.
So, the linear charge density is
λ = q / L
If the length is 12 times, then charge should also be 12 times to keep the linear charge density same.
