number three, there isn't really potential energy inside you, not in the process of the energy transformation of food.

The bottom one makes the most sense because if you think about all of the steps, it goes chemical (stomach acid), there is also some heat in there, and then mechanical when the food moves from place to place

Find the value of W please help due tomorrow

Answers

Answer:

59 degrees

Step-by-step explanation:

All the angles of a triangle (when combined) result in 180 degrees. This means that:

Angle 1 + angle 2 + angle 3 = 180 degrees.

We can see here that the shape here is a right triangle (noted by the square in the corner). This means that the angle set with the square is equal to 90. With this, we already have two of our angles! All we need is to set the equation using w, the angle you'll want to find:

31 + 90 + w = 180

w = 59

And there you are! Make sure to practice a few more problems like these to really get the hang of it. Good luck!

In this diagram, each square represents 1 km. What is the displacement of the car?​

Answers

Answer: C) 2 km west

Explanation:

With displacement, all we care about is the beginning and end. We don't care about the middle part(s) of the journey. So we'll take the straight line route from beginning to end when it comes to computing displacement.

We start at A(0,0) and end at B(-2,0). Going from A directly to B has us go 2 km west. Keep in mind that displacement is a vector, so you must include the direction along with the distance.

What is congruent triangle?

The triangle is said to be congruent, if all the three sides are equal and all the angles are equal.

For the given situation,

Two triangles XOW and YOZ are congruent.

Then the sides, WX and YZ are equal.

Thus the measure of the chord, WX = YZ = 7 units.

Hence we can conclude that the measure of the chord YZ = 7 units.
