Answer:
While slavery was the major issue separating the North and South, it was not slavery itself that sparked the conflict. The South wanted to secede from the Union, and the North refused. While President Abraham Lincoln personally opposed slavery, he recognized that it was legal under the U.S. Constitution at the time. He also recognized that few in the North were ready to go to war to free the slaves. For Lincoln and the northern majority, preservation of the Union was the foremost goal.
That's the "centripetal" force. It produces the centripetal acceleration
that pulls the object away from a straight path into a bent path.
Answer:
Explanation:
Given:
- frequency of the broadcast,
- we have the speed of the radiation equal to the speed of light,
The broadcast waves are the electromagnetic waves but it can travel only upto a hundred kilometers without any loss of information carried by it.
<u>The relation between the frequency and the wavelength:</u>
Answer:
Explanation:
To find the expression in terms of time t you take into account the following equation for the angular distance traveled by an object with angular acceleration w and initial angular position θo:
( 1 )
α is the angular acceleration, but in this case you have a circular motion with constant angular speed, then α = 0 rad/s^2. θo is the initial angular position, the information of the question establishes that Enrique is at 3-o'clock. This position can be taken, in radian, as π/4 (for 12-o'clock = 0 rads).
The angular speed is:
You replace the values of θo, α and w in the equation ( 1 ):
Furthermore, the arc length is:
