With a wooden ruler, you measure the length of a rectangular piece of sheet metal to be 14 mm. With micrometer calipers, you measure the width of the rectangle to be 4.98 mm. Give your answers to the following questions using the correct number of significant figures. What is:

a. the area of the rectangle.
b. the ratio of the rectangle’s width to its length.
c. the perimeter of the rectangle.
d. the difference between the length and the width.
e. the ratio of the length to the width.

Follows are the solution to the given question:

Explanation:

The rectangular part has a length of and its rectangular part has a width of .

In option A

Calculating the area of the rectangular throgh the given piece:

In option B

Calculating the ratio of rectangle's width which is rectangle's length:

So, the ratio of rectangle's width to rectangle's length is 0.3557  .

In option C

Calculating the Perimeter of the rectangle:

In option D

Calculating the difference between length and width:  

In option E

Calculating the ratio of length to width:

28. evolution

explanation:

initial speed when it is dropped is 150 ft/s

now at the same moment the acceleration due to gravity is perpendicular to its velocity

so as we know that

now we have centripetal acceleration a = 32 ft/s^2 as its perpendicular to velocity

while tangential acceleration at the same moment will be zero

so

now radius of curvature is given as

so the radius of curvature just after it is dropped is 703.125 ft
