Aplane starting from rest (vo = 0 m/s) when t0 = 0s. the plane accelerates down the runway, and at 29 seconds, its velocity is +72.2 m/s. (+ indicates to the right). determine the average acceleration for the plane.

Acceleration,

Explanation:

Given that,

The plane is at rest initially, u = 0

Final speed of the plane, v = 72.2 m/s

Time, t = 29 s

We need to find the average acceleration for the plane. It can be calculated as :

So, the average acceleration for the plane is . Hence, this is the required solution.

i am pretty sure it is c because when people are closer together, they cannot move as freely. picture being in a mostly full elevator, for instance. the people are right next to you, and you can barely move.

the answer is the first electromagnet (a). this is because it has more coils around the ferromagnetic material. increasing the number of coils increases the surface area in which the metal interacts with the current in the coil. this enables more atoms in the metal to become aligned hence becoming more magnetized.
