Invention is the creation of a product and innovation is when someone improves on or makes a significant contribution to an existing product.
Answer:
a) Magnitude = 1.03 m/s², Direction: south
b)
Explanation:
a) The magnitude and direction of the acceleration can be calculated using the following equation:
(1)
Where:
: is the final speed = 9.40 m/s
: is the initial speed = 13.0 m/s
t: is the time = 3.50 s
Solving equation (1) for a, we have:
Hence, the magnitude of the acceleration is 1.03 m/s² and the direction of the bird's acceleration is the opposite of the initial velocity direction, which means that the bird is decelerating.
b) The final velocity of the bird can be found using the same equation 1:
Therefore, the bird’s velocity after an additional 1.20 s has elapsed is 8.16 m/s.

An example of Newton's First Law is chewing. You need to start chewing in order for the food to become smaller which involves motion from your teeth and the food which stays in motion until you swallow the food. When you chew, you move the food in a circular motion and when you are ready to swallow, that motion stops and goes into another motion.
Hoped that helped
Answer:
28 revolutions
Explanation:
Here we are going to use the accelerated angular motion formulas.
θ
because it starts from rest, wo=0
θ
θ
The number of revolutions is given by:
So the turbine completed 28 revolutions at that time.
