Answer:
392 Newtons
Explanation:
In order to find the weight, you have to multiply the mass by the gravitation constant (9.8), which gives us 40.0 * 9.8 = 392 Newtons.
Answer:
C
Explanation:
Although the maximin criterion emphasizes the worst-off person in society and it's targeted towards equalizing of the distribution of income by transferring income from the rich to the poor, it will not lead to a complete egalitarian society. Because this will make the people not to have incentive to work hard and the societal total income will substantially fall off and the least fortunate person will be worse off. Thus, this rule still allows disparities in income.
Answer:
what do you mean by that.
The desk is in equilbrium, so Newton's second law gives
∑ <em>F</em> (horizontal) = <em>p</em> - <em>f</em> = 0
∑ <em>F</em> (vertical) = <em>n</em> - <em>mg</em> = 0
==> <em>n</em> = <em>mg</em>
==> <em>p</em> = <em>f</em> = <em>µn</em> = <em>µmg</em> = 0.400 (80.0 kg) <em>g</em> = 313.6 N
The student pushes the desk 3.00 m, so she performs
<em>W</em> = (313.6 N) (3.00 m) = 940.8 Nm ≈ 941 J
of work.
