Answer: the same number of decimal places as the least precise value.
Explanation:
Significant figures : The figures in a number which express the value -the magnitude of a quantity to a specific degree of accuracy is known as significant digits.
The rule apply for the addition and subtraction is :
The least precise number present after the decimal point determines the number of significant figures in the answer.
For example: 12.1 + 3.245 = 15.3 as the least precise number 12.1 has one decimal place.
Thus William should write the sum of these two numbers by using the same number of decimal places as the least precise value.

A) diagram is shown on the image below
b) Mass m = 450/9.8 = 45.918 KgNet upward force = T + T = 2T = 620 NNet downward force = 290 + 160 = 450 NResultant force F = Net upward force - Net downward force ma = 620 - 450 45.918 a = 170 Acceleration a = 170/45.918 =
3.7 m/s^2 (upward)Here Net upward force > Net downward force, So the resultant force directed upwards, hence acceleration will be
upward.
(c)Consider the case of boy alone, then from Newtons law of motion we can write Net force F = n + T - 290 ma = n + 310 - 290 where m = 290/9.8 = 29.59 Kg 29.59 * 3.7 = n + 20 109.483 = n + 20 n =
89.483 N
Answer:
The maximum height to which water could be squirted with the hose is 13.380 meters.
Explanation:
A line of current of a fluid can be explained sufficiently by Bernoulli's Theorem. In this case, the system can be simplified due to neglectance of changes in absolute pressure. Water is squirted with an initial speed and reaches its maximum height, where final speed is zero. That is to say:
Where:
, - Initial and final height of water, measured in meters.
- Gravitational acceleration, measured in meters per square second.
, - Initial and final speed of water, measured in meters per second.
If , , and , then:
The maximum height to which water could be squirted with the hose is 13.380 meters.
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:
A. Gravitational force
C. Their charges
Explanation:
As we'll discuss in this lesson, he found that the force between charged particles was dependent on only two factors: the distance between the particles and the amount of electric charge that they carried.
Hope it help you
have a good day :)
