Answer:
D or 13 is the answer to this problem.
Answer:
The acceleration in the system and in the rope is same as 5.88 m/s2.
Step-by-step explanation:
The figure shows two blocks of m1 = 0.8 Kg and m2 = 0.2 kg if the block of mass m2 is dragged by the block of mass m1 calculate the acceleration of the system and the acceleration of the rope
Let the acceleration is a and the tension in the string is T.
Use Newton's second law
![m_1 g - T = m_1 a ..... (1)\\\\T -m_2 g = m_2 a ......(2)\\\\Add both of them \\\\(m_1 - m_2) g = (m_1 + m_2) a \\\\(0.8-0.2)\times9.8 = (0.8+0.2)a\\\\a = 5.88 m/s^2](https://tex.z-dn.net/?f=m_1%20g%20-%20T%20%3D%20m_1%20a%20.....%20%281%29%5C%5C%5C%5CT%20-m_2%20g%20%3D%20m_2%20a%20......%282%29%5C%5C%5C%5CAdd%20both%20of%20them%20%5C%5C%5C%5C%28m_1%20-%20m_2%29%20g%20%3D%20%28m_1%20%2B%20m_2%29%20a%20%5C%5C%5C%5C%280.8-0.2%29%5Ctimes9.8%20%3D%20%280.8%2B0.2%29a%5C%5C%5C%5Ca%20%3D%205.88%20m%2Fs%5E2)
Answer:
7/12
Step-by-step explanation:
First you have to find a comnon demominator, which is 12.
![\frac{1}{6} *2 = \frac{2}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7B6%7D%20%2A2%20%3D%20%5Cfrac%7B2%7D%7B12%7D)
Next, add them together.
![\frac{2}{12} +\frac{5}{12} =\frac{7}{12}](https://tex.z-dn.net/?f=%5Cfrac%7B2%7D%7B12%7D%20%2B%5Cfrac%7B5%7D%7B12%7D%20%3D%5Cfrac%7B7%7D%7B12%7D)
Answer:
Each gardner will get <u>1/16</u> of a pile of pine needles.
Step-by-step explanation:
1/2 ÷ 8
<em>*Switch the division to multiplication and flip the 8 (or 8/1) upside-down.</em>
= 1/2 · 1/8
= 1/16
