Answer:
a) 79.7rad/s
b) -18.7rad/s^2
c) 53m
Explanation:
We will use the MKS system of unit, so:
now, The angular speed is given by:
in order to obtain the angular acceleration we have to apply the following formula:
The linear displacement is given by:
Answer:
This statement is false.
Explanation:
If the farmers field is close to the stream, and has experienced a lot of runoff, the runoff will carry chemicals from the farm into the stream, which includes fertilizers among other chemicals. This runoff into the stream will not lead to a decrease in the level of fertilizers in the stream. Therefore, one of the effect of this cannot be a decrease in the level of fertilizers from the field.
Answer:
it is zero because the electric gap is zero within the material
Explanation:
In a metal you have many free electrons, and fixed charges formed by nuclei and electrons that are not free; therefore the charge carriers are the free electrons, these have the same negative charge and due to the lectrostatic force they repel each other as far as possible without leaving the material, this implies that at two points there must be the same potential because otherwise there would be a net Caesarian force accumulating charge in a part that would be eliminated by the Coulomb force.
With this we can review the statements the strap is: it is zero because the electric gap is zero within the material
