A Book Of Mass 1kg Is On The Floor If The Book Is Lifted Frome The Floor To The Top Shelf Which Is 2 Meeters Fome The Floor How Much Work Is Done On T

a book of mass 1kg is on the floor if the book is lifted frome the floor to the top shelf which is 2 meeters fome the floor how much work is done on the book.........pls help me to solve my problems?

 

Answer:

W=19.62 N-m

Explanation:

work= force x distance

W= F x d

F = m x gravity

F= 1kg x 9.81 m/s2

F=9.81N

W = 9.81N x 2m

W= 19.62 N-m

What Do You Call The Given Equations?

What do you call the given equations?   Polynomial Equation:         A polynomial equation is any polynomial equated to zero. Examples: x - 2 = 0 x² + 2x + 5 = 0 5x + 1 = 0 x³  - 2x² - 4x + 8 = 0 x(x - 4) = 0 Number of Roots: The number of root(s) of the polynomial equation is based on the highest degree of the exponent it contain. Example #1: x - 2 = 0 the number of root(s) is just 1 since it is a polynomial of the first degree. Example #2: x² + 2x + 5 = 0 the number of root(s) is 2 since it is a polynomial of the second degree. Example #3: 5x + 1 = 0, there is only 1 root because it is a polynomial equation of the first degree. Example #4: x³  - 2x² - 4x + 8 = 0 have 3 roots since its highest degree is 3. Example #5: x(x - 4) = 0 have 2 roots because it is a polynomial equation of the second degree.
