So far i have determined the following equations from the my force body diagrams. T(cos(31)) - mg(sin(25)) = 0 N - (mg(cos(25)) + (T(sin(31))) = 0 to solve for tension you rearrange the first equation to get T(cos(31)) = mg(sin(25)) so if you solve for the horizontal component of gravity you will be able to determine the tension of the string. i have tried my following answer (which comes out to 1426N) but i am incorrect. if anyone can please point out what i am missing i would be really appreciate it.

The standard diameter of a golf ball is 42. 67 mm. A golf ball factory does quality control on the balls it manufactures. Golf b
Fynjy0 [20]

The maximum and minimum acceptable diameter of the golf ball in the factory will be 42.672 mm to 42.668 mm.

<h3>What is the range?</h3>

The range is the difference between the maximum and minimum.

Given to us

The standard diameter of a golf ball is 42.67 mm.

The discrepancy in diameter is more than 0.002 mm.

As it is given to us that the standard diameter of the golf ball is 42.67 mm while the discrepancy in diameter is more than 0.002 mm.

Maximum acceptable diameter = 42.67 mm + 0.002 mm = 42.672 mm

Minimum acceptable diameter = 42.67 mm - 0.002 mm = 42.668 mm

Hence, the maximum and minimum acceptable diameter of the golf ball in the factory will be 42.672 mm to 42.668 mm.

What happens to the value of the expression 2t/t as t decreases
anyanavicka [17]

Answer:

  it stays the same until t=0, where it is undefined

Step-by-step explanation:

2t/t = 2 . . . . when t ≠ 0

2t/t = undefined when t = 0.

The value of t can increase or decrease and the value of the ratio remains the same. The value has a "hole" at t=0, where it is undefined. Otherwise, its value is always 2.
