Answer:
Explanation:
We are being provided with little information about the question in the study.
The 50 ml is required to make an unknown solution which has a mass of 5g,
SO, we are to determine the amount of grams that will be needed to make the product.
We are not given information about the product, as such this will be difficult and impossible to answer.
You can add the additional information required in the comment section below and further explanation and the detailed solution will be provided.
Thanks!!!
its B. Organ b/c the plants root are part of the plant
A force of 8 N will be required.
<h3><u>Explanation:</u></h3>
Mechanical advantage is defined as the ratio of output force from a system to the input force into the system. A machine which has the mechanical advantage more than 1 means it requires less force to give more force as output. Similarly, when the mechanical advantage for the machine is less than 1,it means more force is required to give to achieve a less one.
Here in the question, the mechanical advantage of the pulley is 2.
Output force required to pull the sack of potatoes upto kitchen is 16N.
Mechanical advantage = Output force / input force.
Or, 2= 16 / input force.
So input force = 
So a force of 8 N will be required to pull the pulley.
Answer: No
Explanation:
Mutualism is a kind of symbiotic relationship when two species lives in close association with each other to complete their life cycle. In this relationship both the species receives the benefit of association.
The given situation is not an example of mutualism this is because of the fact that in the association with the microbes the plants are more fit but the situation does not describe the fact that the microbe is also getting any benefit of association.
