Answer:
1) distance walked = 210 m
2) not sure
3) avg speed = total d/ total t = 210/52 = 4 m/s approx
4) For avg vel, use the formula - displacement/time
Explanation:
im not fully sure but i studied this last year
Answer: An object undergoing uniform circular motion is moving
Explanation:
Wind<span> power
holds great promise for the united states because of the great wind power (capacity),
and experts believe wind energy could meet as much as 20 percent of the
nation’s energy needs
. Texas is the state with most wind capacity. On the second place is Iowa and oh the third place Oklahoma. The wind farms produce clean energy that does not harm the environment.</span>
We will apply the concepts related to Newton's second law. At the same time we will convert everything to the system of international units.
The values of the velocities are,
We know that the acceleration is equivalent to the change of the speed in a certain time therefore
Now applying the Newton's second law we have,
Therefore the approximate magnitude is 8516.36N
Answer:
so 9/3=3 current is 3 amperes
