Answer: J. The Industrial Revolution encouraged people to pursue jobs in cities.
Explanation:
The first and second industrial revolutions brought about many inventions and new processes for doing things such that Urbanization took hold fast as factories were built and production of many goods and services was ramped up.
The effect was that many people left agriculture and went to the cities to work in these new factories and this led to the rural population of the United States steadily decreasing.
We know that <span>L=Iω</span>
That is Angular momentum is equal to product of moment of inertia and angular velocity.
Now differentiating with respect to time,
<span>dL/dt=d(Iω)/dt</span>
But we know that the rate of change of angular momentum is equal to net external
torque i.e.
<span>
dL/dt=τ</span>
therefore
if no exterannal torque is acting on the body i.e. <span>
τ=0</span>then <span>d</span><span>L</span><span>/</span><span>d</span><span>t</span><span>=</span><span>0</span>
in other words
<span>d(Iω)/dt=0</span>
because <span>
dL/dt=d(Iω)/dt</span><span>
Hence angular momentum is conserved or angular momentun does not change with time if the net external force acting on the body is zero.
hope this helps</span>
The correct answer is 2.
Elasticity measures the sensibility of the quantity supplied or demanded when the price of the product is modified. In this example we will compute the elasticity of the supply function.
<u>The supply function is inelastic</u> in the sense than when a price increase is performed (from P1 to P2) the quantity supplied increases in a lower proportion (from Q1 to Q2). Let's prove this by calculating the percentage increase experienced by each of the two variables:
- Price: (7-4)/4 * 100% = + 75%
- Quantity supplied: (5-3)/3 * 100%= +66.66%
When there is a price increase of the 75%, the quantity supplied increases a 66.66% (<75%).
A city is legally defined in the United States as an urban unit with clear boundaries and a degree of autonomy. Also, it is defined as a large and permanent human settlement or area.
The answer would be letter D.
Mass media help people recognize the biased opinions.
Explanation:
Mass media like Television has become crucial in educating and informing people about what is right and what is wrong. When a person is informed enough about a certain thing, he is able to better recognize the biases in other people, and this makes him becoming a better informed citizen of the society.
For example, you come to know about the corruption of a politician through television in many cases in which that politician has stolen money of the country, and during the election season, some people from his party come to ask for the vote, but because you are well informed about the character of that politician for whom the people are asking for vote, you will not vote for that politician in the coming elections. This is the power of mass media and this is how mass media has helped people recognizes the biases and helped a person becoming a well informed citizen.
