Suppose the work required to stretch a spring from 1.1m beyond its natural length to a meters beyond its natural length is 5 J,

Nadya [2.5K]

Answer:

Explanation:

The formula for the work done on a spring is:

$W = \frac{1}{2}kx^{2}$

where k is the spring constant and x is the change in length of the string

For the first statement,

x = (a-1.1), W = 5

=> $5 = \frac{1}{2}k(a-1.1)^{2}$

Now making k the subject of formula, we have:

$k = \frac{10}{(a-1.1)^2} ---------------- (A)$

For the second statement,

x = (a-4.8), W = 9

=> $9 = \frac{1}{2}k(a-4.8)^{2}$

Now making k the subject of formula, we have:

$k = \frac{18}{(a-4.8)^{2} } ------------------------- (B)$

Equating A and B since k is constant, we have:

$\frac{10}{(a-1.1)^{2} } = \frac{18}{(a-4.8)^{2} }$

solving for the value of a

$8a^{2} +56.4a-208.62=0$

solving for a, we get:

a = 2.6801 or -9.7301

but since length cannot be negative, a = 2.68m

substituting the value of a in equation B, we have:

$k=\frac{18}{(2.68-4.8)^{2} }$

k = 4.005

Public static void prefixmerge(customer[] list1, customer[] list2, customer[] result {

White raven [17]

I can't get what do you need, but I guess it's a part of java code. I can explain what it means. It's used to unite two rising sorted arrays which are list1 and list2. The result is stored in result array. I suggest you to clearly explain your task as it's difficult to give you correct answer.

A network with 10 bits remaining for the host portion will have how many usable host addresses?

makvit [3.9K]

Answer:

2^10 = 1024 addresses

Explanation:

Each bit can be either 1 or 0, and this holds true for all 10 bits. So for every bit, we choose either a 0 or a 1 (2 choices), and then do so for the remaining bits. So we have 2 * 2 * 2 * ... * 2 (10 2's) choices for all 10 bits

The general case in a recursive function is the case for which the solution is obtained directly.

Reika [66]

Answer: False.

Explanation:

The general case of recursive function is when the solution is obtained recursively by simplification at each step.

However, it is the base case in a recursive function when the solution is obtained directly.

The general case must be reducible to base to arrive at a solution else the recursion would be a infinite recursion.

Linda installed a special pool for the hydrotherapeutic treatment of severe arthritis, as prescribed by her doctor. The cost of

stellarik [79]

Answer:

Linda is entitled to deduction (before any AGI limitations) of $896 in one year of installation of the pool.

Explanation:

Following is explained calculation for deduction (before any AGI limitations) that is Linda entitled to in the year of installation of the pool.

Given that:

Cost of Installing the pool = $22,400

Paid by insurance company = $5,600

So by deducting the price paid by insurance company from total cost the balance becomes:

Balance = $22,400 - $5,600 = $ 16,800

As the pool increased the value of house by $7,840 so we will deduct this amount from balance:

Balance = $ 16,800 - $7,840 = $8,960

As the useful life given for pool is 10 years so we will divide the balance with 10 to obtain the deduction amount for 1 year:

Deduction amount for one year = $8,960/10 = $8,96

Hence $8,96 will be deducted in one year installation.

i hope it will help you!
