It takes 87 j of work to stretch an ideal spring, initially 1. 4 m from equilibrium, to a position 2. 9 m from equilibrium. What is the value of the spring constant (force constant) of this spring?.
The spring undergoes a change in potential energy of
1/2 k (2.9 m)² - 1/2 k (1.4 m)² = 87 J
Solve for k :
k ((2.9 m)² - (1.4 m)²) = 174 J
k = (174 J) / ((2.9 m)² - (1.4 m)²)
k ≈ 27 N/m

Place the events that form hurricane-force winds in order.
Answer: The events that form hurricane-force winds are as follows
1. Tropical disturbance
2. Tropical depression
3. Tropical storm
4. Hurricane.
Explanation:
All of the above-mentioned events happen in chronological order for the hurricane-force winds to occur.
1. Tropical disturbance occurs from the tropics and the subtropics. These are generally 100-300 miles in diameter. It is a tropical weather system of organized conventions. This is the first stage that consists of a loosely organized low-pressure area.
2. Tropical depression is a more organized deep convention and has a closed circulation of sustained winds of less than 39 mph.
3. Tropical storm is the third stage that has sustained winds between 39 - 73 mph.
4. The hurricane is created when the sustained winds finally reach or cross the speed of 74 mph.
This is how hurricane-force winds are created.

The time that customers wait to be served at the deli for a grocery store follows the uniform distribution between 0 and 7 minutes. What is the probability that a randomly selected customer will wait more than 4 minutes at the deli?.
The probability that a randomly selected customer will wait more than 4 minutes at the deli is given below
The probability that a randomly selected customer will wait more than 4 minutes = [tex]0.4286[/tex]The waiting time for the customers is uniformly distributed between 0 - 7 minutes
Consider a random variabe X that represents the waiting time of customers and uniformly distributed between 0-7 minutes
Therefore, the density function of X is determined as
[tex]f(x) = \frac{1}{b-a}\\\\f(x) = \frac{1}{7-0}\\\\f(x) = \frac{1}{7}[/tex]
The probability that the customer will wait more than 4minutes,
[tex]P(X>4) = \int\limits^7_4 f{x} \,dx\\\\= \int\limits^7_4 \, \frac{1}{7}dx\\\\= \frac{1}{7} * [x]^7_4\\\\= \frac{7-4}{7} \\\\= 0.4286[/tex]

pizza with peparoni or pizza with mustard and pinaple choose wisley ; -)
Answer:
This is an SAT question, so I will be proofreading this for grammar.
The first pizza should be capitalized.

Pinaple is spelled wrong
wisely is spelled wrong
There should be a period between "pinaple" and "choose"
The first half beginning with "pizza" and ending with "pinaple" is an incomplete sentence.
By the way, I would prefer pineapple.
