22%. Make it a percent and it'll be 22%.
All you do is add up all your sides! So if your shape has 4+4+5+5 = 18. All you do is add them up!
What do you need to finish
Answer:
see the explanation
Step-by-step explanation:
we know that
If two lines are perpendicular, then their slopes are opposite reciprocal (the product of their slopes is equal to -1)
In the coordinate plane, the x axis (y=0) and y axis (x=0) are perpendicular
however
this definition does not apply to the lines y=0 and x=0.
because
The slope of the horizontal line y=0 is equal to zero and the slope of the vertical line x=0 is undefined
A cardboard box rests on the floor of an elevator. The box has a mass m = 3.75 kg and the elevator has an upward acceleration of a
Part a. Select the Free Body Diagram for the system
Part b. Write an expression for the sum of the forces actinv on the box in the y direcion, given that up is the positive y direction. Your answer should be in terms of FN, m, g.
Part c. Write an expression for the normal force FN, that the block experiences in terms of the elevator's accelaration, the block's mass and the accelaration of gravity
Part d. If the elevator's accelaration has a magnitude of g in the downward direction, what would the normal force FN1 be in Newtons? (Numerical value)
Part e. If the elevator's accelaration had a magnitude of g in the upward direction, what would the normal force FN2 ve in Newtons? (Numerical value)
