Answer:
Speed of water at the top of fall = 5.40 m/s
Explanation:
We have equation of motion
Here final velocity, v = 26 m/s
a = acceleration due to gravity
displacement, s = 33 m
Substituting
Speed of water at the top of fall = 5.40 m/s
Answer:
1. authority - power to enforce laws
2. unalienable - something that cannot be taken away
3. declaration - a forceful statement
4. self-government - the right to govern oneself
Explanation:
1. Authority- power to enforce laws
<u>It is the power that is being practice by either a person or a group of people over their subjects. </u>The person uses this power<em> in order to cause an action.</em> For example, the CEO of Mitsubishi will decide on what supply manufacturer they will choose. This means that he has the authority over this area. He does this in order for the company to achieve its organizational goal more efficiently.
2. Unalienable - This is also synonymous to the term "inalienable."
<u>This is something that cannot be taken away from a person, such as the right to live, to have liberty and to find happiness.</u> This is a popular term used in the "Declaration of Independence," in which American colonists disclosed their grievances under King George III in order to attain independence. This right cannot be revoked or transferred, nor is it negotiable.
3. Declaration - t<u>his is a forceful statement or an announcement of something that is deemed important. </u>This also considered an official statement and is disclosed to public for an intended purpose. Regarding specific cases, a declaration refers to stating the facts that serves as a ground to support the case. It can includes many sections that explains the reasons why actions were made.
4. Self-government -<u> </u><u>this is the ability of a person or group to do things on their own or have control without the influence or authority from outside. </u>When it comes to economy, this refers to the rule of the people. This can also be practiced in school, whereby students participate in making the school laws and enforcing them as well. This is a common characteristic for democratic countries where people has a say in the society.
Answer:
Power output: W=1426.9MW
Explanation:
The power output of the falls is given mainly by its change in potential energy:
The potential energy for any point can be calculated as:
If we consider the base of the falls to be the reference height, at point 2 h=0, so P2=0, and height at point 1 equals 52m:
If we replace m with the mass rate M we obtain the rate of change in potential energy over time, so the power generated:
Answer:
D) F
Explanation:
Let m and M be the mass of the balls A and B respectively and r be the distance between the two balls. The magnitude of attractive gravitational force experienced by the balls due to each other is given by the relation :
......(1)
Now, if the masses of both the balls gets doubled as well as there separation distance also gets doubled, then let F₁ be the new gravitational force acting on them.
Since, New mass of ball A = 2M
New mass of ball b = 2m
Distance between the two balls = 2r
Substitute these values in equation (1).
Using equation (1) in the above equation.
F₁ = F
Answer:
The mother has to sit 2.17 ft from the center on the other side of the seesaw.
Explanation:
We are trying to find the sum of torques given by the weights of mother and daughter to be zero.
If the torque of the daughter on one side of the pivoting point is given by:
5.5 ft x 63.5 lb x g = 349.25 g ft lb
we need that the absolute value of the torque exerted by the mom (160.9 lb) to be the same in magnitude (and of course opposite direction). So we assume that "d" is the distance at which the mother locates to make this torque equal in magnitude to her daughter's torque:
d x 160.9 lb x g = 349.25 g ft lb
d = 2.17 ft
