Mechanical advantage = ideal mechanical advantage x efficiency = 3.5 * 0.6= 2.1.
The mechanical advantage of the inclined plane is 2.1.
Hope this helps!
Can u plz mark me as brainliest? I really need it!
Answer:
48.4293354946 N
Yes
Explanation:
d = Diameter of rod = 2.95 cm
h = Length of rod = 92.6 cm
= Density of rod = 7800 kg/m³
g = Acceleration due to gravity = 9.81 m/s²
Volume of rod
![V=\dfrac{1}{4}\pi d^2h\\\Rightarrow V=\dfrac{1}{4}\times \pi\times (2.95\times 10^{-2})^2\times 92.6\times 10^{-2}](https://tex.z-dn.net/?f=V%3D%5Cdfrac%7B1%7D%7B4%7D%5Cpi%20d%5E2h%5C%5C%5CRightarrow%20V%3D%5Cdfrac%7B1%7D%7B4%7D%5Ctimes%20%5Cpi%5Ctimes%20%282.95%5Ctimes%2010%5E%7B-2%7D%29%5E2%5Ctimes%2092.6%5Ctimes%2010%5E%7B-2%7D)
Mass is given by
![m=\rho V\\\Rightarrow m=7800\times \dfrac{1}{4}\times \pi\times (2.95\times 10^{-2})^2\times 92.6\times 10^{-2}\\\Rightarrow m=4.93673144695\ kg](https://tex.z-dn.net/?f=m%3D%5Crho%20V%5C%5C%5CRightarrow%20m%3D7800%5Ctimes%20%5Cdfrac%7B1%7D%7B4%7D%5Ctimes%20%5Cpi%5Ctimes%20%282.95%5Ctimes%2010%5E%7B-2%7D%29%5E2%5Ctimes%2092.6%5Ctimes%2010%5E%7B-2%7D%5C%5C%5CRightarrow%20m%3D4.93673144695%5C%20kg)
Weight is given by
![W=mg\\\Rightarrow W=4.93673144695\times 9.81\\\Rightarrow W=48.4293354946\ N](https://tex.z-dn.net/?f=W%3Dmg%5C%5C%5CRightarrow%20W%3D4.93673144695%5Ctimes%209.81%5C%5C%5CRightarrow%20W%3D48.4293354946%5C%20N)
The weight of the rod is 48.4293354946 N
The mass of the rod is 4.93673144695 kg which is light. So, I will be able to carry the rod without a cart.
Land animals could eat water animals
For example, a bear could eat salmon from the river and that could be connected to organisms from water to land
In 5,728 Joules is about 5.4290965 BTU (British Thermal Unit).
