In your own words, describe how the energy of a pendulum is changed as it moves through one cycle of its motion. Pls help online school sucks

Answers

In a perfect world without air resistance, the top of the swing would have the most potential energy, but the least amount of kinetic energy. As the pendulum falls down, it gains more kinetic energy as it travels faster due to gravitational acceleration but loses more potential energy as it loses height. The total amount of energy in the system (the sum of kinetic and potential energy) stays the same.

The energy of a pendulum is changed from Kinetic to Potential Energy (and vice-versa) when it moves through one cycle of its motion.

What is Kinetic Energy ?

The kinetic energy of an object is the energy that it possesses due to its motion and is defined as the work needed to accelerate a body of a given mass from rest to its stated velocity.

Having gained this energy during its acceleration, the body maintains this kinetic energy unless its speed changes.

When we move the bob of the pendulum to start the movement you "charge" it with Potential Energy (Gravitational) by varying its position (height) in relation to the ground.

When we release the bob it moves towards the equilibrium position changing Potential into Kinetic Energy (through the movement with Velocity).

At the equilibrium point the bob doesn't stop but goes on up to the same height "re-charging" it with Potential Energy.

The sum of Kinetic (K) and Potential (U) Energy (called Mechanical Energy is always the same:

E = K + U = constant

Therefore, The energy of a pendulum is changed from Kinetic to Potential Energy (and vice-versa) when it moves through one cycle of its motion.

(50 POINTS) Why does the radius of an atom increase as you go down a group on the periodic table?

A) because you are increasing the size of the electrons, which takes up more space

B) because you are adding another outer level of electrons, further from the nucleus

C) because you are adding more neutrons, which reduces the attraction between proton and electron

D) because you are decreasing the pull by the nucleus, allowing the electrons to travel further away

Answers

Answer:

B

Explanation:

The atomic radius increases as you go down a group in the periodic table. Atoms get larger because more electrons are being added in higher energy levels, and each energy level is further from the nucleus than the last. Therefore, the atomic radius increases as you go down a group.

Which element does not have similar chemical characteristics as phosphorus (P)?

answers:
Antimony (Sb)
Nitrogen (N)
Arsenic (As)
Oxygen (O)

Answers

Generally (but far from universally), the elements within a group have similar characteristics. Antimony, nitrogen, and arsenic are all part of the same group as phosphorous (the pnictogens, or group 5A). Oxygen is not in this group, but rather in an adjacent group (the chalcogens, or group 6A). Thus, the answer here should be oxygen.

That said, there can be very significant differences in characteristics among the elements within a group, and that is certainly the case here. For example, free nitrogen exists predominantly as a molecular gas (N₂) and makes up about 78% of the atmosphere we breathe. Elemental arsenic (As), while in the same group as nitrogen, is naturally found in the solid state and is poisonous to humans (arsenic is sometimes included among the toxic heavy metals, although it’s technically a metalloid).

Just as some elements attain a noble gas configuration by gaining some extra electrons, other elements can more easily gain that configuration by losing some electrons. For a sodium atom, it is simply closer to get to the same configuration as neon than it is to get to the same configuration as argon.

8. Converting Units The volumes in your data are in millimeters, which are equivalent to cubic centimeters, cm3. But your areas are in units of square meters (m2). To combine these, you will have to convert to similar units. Convert one of your volume measurements from units of cm3 to units of m2, showing your work. (Remember that 1 ×106 cm3 = 1 m2.)

Answers

Answer:

This question is a practical question and hence incomplete

Explanation:

However, there are some steps that can be followed to achieve the aim of this question.

To convert millimeters (mm) to cubic centimeters (cm³), the value in millimeter will have to be divided by 1000. This is because 1 mm equals 0.001 cm³. Hence, if the volume in the data is 30 mm, the equivalent in cm³ will be

30/1000 = 0.03 cm³

OR

1 mm ⇒ 0.001 cm³

30 mm ⇒ ?

Let's assume the unknown (?) is X

1 × X = 30 × 0.001

X = 0.03 cm³

Hence, 30 mm equals 0.03 cm³

Also, to convert any volume from cubic centimeter (cm³) to square meter (m²), you will divide the unit in cm³ by 1 × 10⁶ (1,000,000). To convert the value obtained earlier (0.03 cm³ or 3 × 10⁻² cm³) to m², you will

1,000,000 cm³ ⇒ 1 m²

0.03 cm³ ⇒ ?

Let's assume the unknown (?) is Y

1000000 × Y = 0.03 × 1

Y = 0.03/1000000 OR you can write it as 3 × 10⁻² × 10⁻⁶

Y =  3 × 10⁻⁸m²

Hence, 0.03 mm equals 3 × 10⁻⁸ m²
