Question

A 6-column table with 2 rows. The first column labeled number of washers has entries 1, 3. The second column labeled Mass of Washers m subscript w (grams) has entries 4.9, 14.7. The third column labeled Mass of Washers m subscript w (kilograms) has entries 0.0049, empty. The fourth column labeled Acceleration due to Gravity a subscript g (meters per seconds squared) has entries empty, 10. The fifth column labeled Force of gravity on the washers F subscript g (kilograms times meters per second squared) has entries 0.049, 0.147. The sixth column labeled Applied force of washers on the car F subscript w c (Newtons) has entries 0049, empty.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~


A) The acceleration due to gravity for any object, including 1 washer on the string, is always assumed to be ___ m/s2.


B) The mass of 3 washers, when converted to kg, is ___ kg.


C) The applied force of 3 washers will increase the applied force on the car to ___ N.


Please find the blanks, thank you!

Answer 1

Your answer is:

Step-by-step explanation:

A) The acceleration due to gravity for any object, including 1 washer on the string, is always assumed to be 10 m/s2.

B) The mass of 3 washers, when converted to kg, is 0.0147 kg.

C) The applied force of 3 washers will increase the applied force on the car to 0.147 N.

I hope this helps!

Answer 2

A) 10 m/(s^2)

B) 0.0147 kg

C) 0.147 N

Step-by-step explanation:

A) It's stated in the table that the acceleration due to gravity is assumed as 10 m/(s^2). If you assume this value in one calculation, then you have to assume the same value in all your calculations.

B) 3 washers have a mass of 14.7 grams. Dividing this mass by 1000, you convert grams into kilograms, that makes 0.0147 kg.

C) Force measured in kilograms times meters per second squared are equivalent to Newtons, therefore, 0.147 kg*m/(s^2) = 0.147 N
