The maximum possible resultant is (5 + 7) = 12N . It occurs
when both forces act on the object in the same direction.
The surface of the stone which he should put on the ground is the base.
<h3>What is a Base?</h3>
This is defined as the flat end which is usually located at the bottom with a larger surface area.
The large surface area helps to distribute the forces on all parts thereby preventing it from sinking.

<u>13788 J is required to finish the work.</u>
Explanation:
Given that,
Mass of lawnmower is 20 kg
Force = 30 N
Displacement ( distance moved )= 20m
The force of 30N is applied along the direction of motion and was applied for the whole 20 m.
The formula of work done for one pass is
Substituting the given data into the formula,
W = 459.6 J
Work done for one pass = 459.6J
Now, work done for 30 passes is calculated by multiplying the work done for one pass into 30.
Work is done by the person pushing the mower to finish the work is <u>13788 J</u>.
The control group is the independent variable and the experimental group is the dependent due to change during the experiment. The experimental group will usually rely on another variable in the experiment for change.
Answer: The reason weight for average adult is 530N
Explanation: The clearly see this answer, let's convert this weight to kg using F=mg
530=m×9.8
g is a constant of 9.8m/s2
We divide both sides by 9.8 to get
54kg then this weight is reasonable for an average adult.
