Answer:
New location at time 3.01 is given by: (7.49, 2.11)
Explanation:
Let's start by understanding what is the particle's velocity (in component form) in that velocity field at time 3:
With such velocities in the x direction and in the y-direction respectively, we can find the displacement in x and y at a time 0.01 units later by using the formula:
Therefore, adding these displacements in component form to the original particle's position, we get:
New position: (7 + 0.49, 2 + 0.11) = (7.49, 2.11)
Take a lamina with three holes near the periphery of the lamina, now suspend the lamina through them, one by one. Draw a line of equilibrium for each suspension point. The point of intersection of these three lines would be the centre of gravity.

Answer:
In wind turbines, the blades rotate due to the wind.
Explanation:
In wind turbines, the blades rotate due to the wind.<u> While the blade rotates the generator connected to it also rotates.</u> Thus the <u>kinetic energy from the wind initiates the electric generator which in turn produces the electricity.</u>
Thus the<u> kinetic energy of the wind is converted to electricity.</u>

Answer:
Explanation:
The formula that relates angular displacement with angular acceleration is:
We can obtain 
from the definition of angular acceleration:
Putting all together:
Which, since we want the angular acceleration, is:
And for our values is:
