Answer:

360°

Explanation:

Quadrilateral are polygons that have four sides. The sum of internal angle of a quadrilateral is 360°. The quadrilateral are closed shape with four sides. Examples of quadrilaterals are trapezium, rectangle, square, Rhombus and parallelograms.

Every quadrilaterals can be divided into two triangle. The sum of angle in a triangle is 180°. Adding the two triangle angle together , we will get the sum as 360°.

Sum of the interior angle of a polygon = 180(n-2) . In the case of quadrilateral, it has 4 sides. n represents the number of sides of the polygon .

interior angle of a quadrilateral = 180(4-2) = 360°

The image illustrate how the interior angle of quadrilaterals can be sum.

Which of the following is a possible use for nuclear energy?

belka [17]

<span>Nuclear energy can be used to power all of the above choices. Nuclear power plants produce radioactive waste that must be stored properly. It is very impossible for a nuclear power plant to have no waste at all since lots of chemicals are used to create the process as it gives energy to other machines, weapons such as bombs and powering submarines. Radioactive waste can not be released into local water supplies since the wastes are very radioactive and may cause mutation to the fishes and bioaccumulation which will affect humans as well. It will also cause air pollution if the chemicals are not stored properly.</span>

A proton and an electron are released from rest, with only the electrostatic force acting. Which of the following statements mus

lbvjy [14]

Answer:

their electrical potential energy decreases. True, because of the negative sign as the distance decreases, it becomes more negative.

The kinetic energy increases. True, the force is attractive as the distance decreases the force increases, so acceleration and therefore the speed

Explanation:

The only force between the proton and the electron is electric

Fe = k q1q2 / r2

Fe = - k e2 / r2

We can see that it is an attractive force (negative sign)

The electric power energy is

U = k q1 q2 / r

U = -k e2 / r

The kinetic energy is

K = ½ m v2

With the expressions for each term we can analyze the sentences :

Their electric potential energy increases. False,

their electrical potential energy decreases. True, because of the negative sign as the distance decreases, it becomes more negative.

The kinetic energy increases. True, the force is attractive as the distance decreases the force increases, so acceleration and therefore the speed

Kinetic energy decreases False

The acceleration decreases. False, as the force increases so does the acceleration
