Answer:
it increases the amplitude of the wave as it propagates.
Explanation:
Answer:
increase.
Explanation:
According to the newton’s second law of motion force is expressed as product of mass and acceleration.
F = m a
If the force acting is constant, then.
m∝ 
That is if the mass of object increases the acceleration decreases and vice versa. The above equation is used when the force acting on the body is constant.
As the thrust force from the rocket engine is constant throughout there will be a variation in the mass or acceleration.
Thus, it won't stay the same.
As the weight of the car is maximum at the start because of the fuel present in the rocket engine and minimum at the end as the fuel burns throughout the journey of the car. Weight will be minimum at the end and hence acceleration is maximum at the end.
Thus, it won't decrease.
As the acceleration is going from minimum at the start to maximum at the end, therefore it is continuously increases throughout its journey.
Thus, it will increase.
A decagram is 1000 times bigger than a centigram
Answer:
30m/s^2
Explanation:
Acceleration=Final Velocity-Initial Velocity/Time
10m/s^2= Final Velocity-0m/s/3
30m/s^2= Final Velocity
Final Velocity=30m/s^2
