Haloke does 176 J of work lifting himself 0.300m at a constant speed. What is Haloke's mass?

Answers

Answer 1

Answer: Since he's lifting himself at constant speed ... not accelerating ... the net vertical force on
him is zero, meaning that he must be lifting with force that's exactly equal to his weight.

Potential energy he added during the lift = (mass) x (gravity) x (height)

Mass = (energy) / (gravity x height) = 176 / (9.8 x 0.3) = 59.864 kg

According to the periodic table, the average atomic mass of helium is A) 2 amu. B) 2.0026 amu. C) 4.0026 amu. D) 6.0026 amu.

Answers

Answer:

C) 4.0026 amu

Explanation:

Helium (He) is the 2nd element on the Periodic Table.

It's neutral atom has 2 protons and 2 electrons.

It is in the 1st period and the 18th row.

It is also a Noble gas.

How do charges move through an insulated wire connected across a battery? Use the terms potential difference, current, conductor, and insulator in answer.

Answers

The battery has both a positive side and a negative side. The potential difference will be the potential of the positive end of the battery minus the potential of the negative end, which will result in positive potential, or power. This potential is what gives the electrons the ability to flow from the positive end to the negative end, or to make a current. While the outside of the insulated wire is the insulator, the inside of the wire has copper, which is the conductor of the current. So, this current will go through the copper of the wire (and not the insulator) from the positive side to the negative.

Answer:

Battery is the source of electrical energy which will help the charge to flow through a medium.

Battery is a constant source of potential difference which will create constant potential difference across the ends of a conductor where it is connected.

When a charge is passed through the constant potential difference then the change in electrostatic potential energy will give kinetic energy to the charge.

It is given as

$q\Delta V = (1)/(2)mv^2$

so here charge will continuously flow through the conductor across which potential difference is applied by the battery. This constant motion or flow of charge is known as electric current.

As you run toward a source of sound, you perceive the frequency of that sound to

Answers

As you run toward a source of sound, you perceive the frequency of that sound to decrease.

Explanation:

Doppler's effect is a principle used to describe the frequency and the intensity of sound and wavelengths of a source and observer with the two possibilities.

(i) Stationary sound source and moving observer.

(ii) Moving sound source and a stationary observer. It is a relative motion.

Consider when the observer is moving towards a source, the frequency of the sound will be higher and when moving away from the source, the frequency will decrease.

frequency is the speed of vibration and this determines the pitch of the sound. it is only useful or meaningful for musical sounds. where there is a strongly regular waveform. frequency is measured as the number of wave cycles that occur in one second. the unit that is being measured is (hz)

Which of the following families contains elements that will not form compounds?

Answers

The answer is:

noble gases will not form compounds.

The explanation:

-The noble gas family, all of the elements in Group Zero.

-The list of noble gases include helium(He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and radon (Rn).

- these elements don't like to react, we don't use them because of they have 8 valence electrons already and don't like to lose or gain electrons so, they will not form compounds.

Noble gases because they have 8 valence electrons already
