The work done by the force in 10 seconds is 250 Joules

<h3>Workdone definition?</h3>

This is the product of force and distance covered by a body

The formula for calculating the workdone is expressed as:

  • W = Fdsin theta

From the information given

Workdone = 25* (2*10) sin 30

Workdone = 500(0.5)

Workdone = 250 Joules

Hence the work done by the force in 10 seconds is 250 Joules

Which of the following sets of sides does not form a right triangle?
kolezko [41]

Answer:

7, 24, 26

Step-by-step explanation:

6 squared is 36 and 8 squared is 64. Add them together and you get 100, which is 10 squared. Do the same for the other ones and you'll notice that 7 squared and 24 squared added together is 625, which is not 26 squared. In my head 25 squared is 625(check if you don't believe me) so I know that the answer is the third one. The basic formula for a right triangle is a^2 + b^2 = c^2, and that's how you find if three numbers form a right triangle or not. Hope this helps :)

The length of a rectangle is 6 inches longer than its width. the perimeter of the rectangle is 28 inches. if x represents the wi
bixtya [17]

I hope choice must be given so that we can select which equation can be used to find its value.

I am showing the steps for this problem.

Given that, x represents the width of the rectangle and the perimeter of the rectangle is 28 inches.

Let's assume y represent the length of the rectangle.

Formula to find the perimeter of a rectangle is,

p= 2 * length + 2 * width.

Hence, we can set up an equation as following.

2 y + 2x = 28.

Hope this is your question, if not I think you will, still be able to

find an answer of your question based on this solution.

Hope this helps you!.
