Changing chemical energy to thermal energy.

Changing nuclear energy to radiant energy.

Explanation:

Changing chemical energy to thermal energy and changing nuclear energy to radiant energy are both examples of transformation of potential energy to kinetic energy.

Potential energy is the energy at rest of a body. There are different forms of potential energy which are :

Gravitational potential energy
Nuclear energy
chemical energy
Electric potential energy
Elastic potential energy

kinetic energy is the energy due to the motion of particles in a medium. Examples are:

thermal energy
mechanical energy
radiant energy
electrical energy
sound energy
wave energy

An airplane flies northwest for 250 mi and then west for 150 mi. What is the resultant displacement of the plane after this time

Kazeer [188]

Answer:371.564 mi

Explanation:

Given

Airplane flies northwest for 250 mi and then travels west 150 mi

That is first it travels 250cos45 in - ve x direction and simultaneously 250sin45 in y direction

after that it travels 150 mi in -ve x direction

So its position vector is given by

$r=-250cos45\hat{i}-150\hat{i}+250sin45\hat{j}$

$r=-\left ( 250cos45+150\right )\hat{i}+250sin45\hat{j}$

so magnitude of displacement is

$|r|=\sqrt{\left ( \frac{250}{\sqrt{2}}+150\right )^2+\left ( \frac{250}{\sqrt{2}}\right )^2}$

|r|=371.564 mi

What type of contraction requires the greatest amount of tension?

mars1129 [50]

Answer:

Isotonic eccentric

Explanation:

First of all, it should be noted that the term contraction has the meaning of joining or shortening. In the field of bodybuilding and workouts with loads, we can define muscle contraction as what happens whenever muscle fibers generate a tension in themselves.

This tension situation occurs in several situations, including when the muscle is shortened, elongated, moving, maintaining the same length or static.

There are different types of muscle contraction, among them we can highlight isotonic contraction, which is divided in turn into concentric and eccentric, isometric, auxotonic and isokinetic contraction.

Isotonic contraction is the most common type of contraction that occurs in most sports or physical activities that we perform in our day to day. Normally the muscular tensions that we exert are usually accompanied by a shortening and lengthening of the muscle fibers of a muscle. In turn, the isotonic contraction is divided into two, concentric and eccentric.

Concentric concentration: is that which happens when a muscle makes a tension capable of overcoming a resistance, producing a shortening and subsequent mobilization of a part of the body overcoming said resistance. For example, when we take a spoon and take it to our mouths to eat, a concentric shortening occurs. Putting examples in the gym on the bench press the movement of raising the bar, is equivalent to the concentric phase.

Eccentric concentration: we can say that it is one in which, given a resistance, we exert a greater tension with the muscle, so that said muscle is lengthened. In the case of the bench press, the eccentric phase is when we lower the bar to the chest.

Consider a ball rolling down the decreasing slope inside a semicircular bowl (the slope is steep at the top rim, gets less steep

satela [25.4K]

The answer would be:
<span>It's rate of gaining speed decreases.
The rate at which speed changes is called acceleration,
You can think of this problem as an inclined plane. But the angle of an inclined plane is constantly decreasing.
We know that on a frictionless inclined plane acceleration of an object is:
</span> $a=gsin(\theta)$
<span>Where g is the gravitational acceleration of the Earth and $\theta$ is the angle of an inclined plane.
Using our analogy, the ball would start on an inclined plane with a 90-degree angle and that angle would continue to decrease to zero.
The sine function is 1 at 90 degrees and is equal to zero at 0 degrees. Since our acceleration is proportional to the sine, and sine function is decreasing with the angle, our acceleration is also decreasing.
