The density of water is 1.00 g/cm3. The density of ethanol is 0.80 g/cm3. What is the volume of ethanol, in cm3 that has the same mass as 100 cm3 of water?

Answers

Answer 1
Answer:

Explanation:

Given that,

The density of water is 1 g/cm³

The density of ethanol is 0.8 g/cm³

We need to find the volume of the ethanol that has the same mass as 100 cm³ of water.

Density=mass/volume

For water,

d=(m)/(V)\n\nm=dV\n\nm=1\ g/cm^3* 100\ cm^3\n\nm=100\ g

For ethanol,

d=(m)/(V)\n\nV=(m)/(d)\n\nV=(100\ g)/(0.8\ g/cm^3)\n\nV=125\ cm^3

Hence, 125 cm³ of ethanol has the same mass as 100 cm³ of water.

Describe two reasons why an alpha particle is less penetrating than a beta or gamma particle.

Answers

Alpha particles travel through the air they collide with oxygen and nitrogen molecules. While they collide with these molecules, they lose some energy until all energy are used up and they are absorbed. These particles can be absorbed by a sheet of paper or by the air. On the other hand, beta particles and gamma particles move faster than the alpha particles and are poor at ionizing atoms or molecules thus it takes more of the material to be able to absorb these particles.

Answer:

1. Heavy mass

2. greater charge

Explanation:

An alpha particle has two protons and two neutrons. It has +2 e charge. It is a heavy mass particle. Thus, when it tends to penetrate even a thin sheet, it loses its energy very quickly because of its interaction with the material particles.

Beta particle is a high energy electron or positron. It carries 1 unit charge and has very less mass in comparison to an alpha particle. Thus, it has more penetrating power than alpha particle.

A gamma particle is charge less and mass less highly energetic particle. Thus, it has highest penetrating power.

Which of the following helps support the argument that light behaves like a particle? A. Sound, which travels in waves, can't travel through a vacuum.
B. Interference is observed with light.
C. Diffraction is observed with light.
D. Unlike sound, light waves don't need a medium to self-propagate

Answers

The correct answer to the question is : D) Unlike sound, light waves don't need a medium to self-propagate

EXPLANATION:

Before coming into any conclusion, first we have to understand the nature of sound and light.

A sound wave is a longitudinal wave which requires a medium for its propagation.  It can not move in space as space contains no material medium for its propagation.

Light is normally considered as electromagnetic wave which does not require any medium for its propagation. It can travel in space also.

The interference and diffraction can not be explained by the particle nature of light.

Hence, the argument that partially support that light behaves just like a particle is the last statement i.e Unlike sound, light waves do not need a medium to self-propagate.
 Sound, which travels in waves, can't travel through a vacuum. 

As there is no matter in vacuum then sound cannot be transmitted. But the transmission of light is quite different, its particle and wave nature is well suited for travel in vacuum.

If the voltage in a circuit is 24 V and the current is 2 A, what is the total power in the circuit?

Answers

V = Voltage in the circuit = 24 Volts

i = Current flowing in the circuit = 2 A

P = Total power dissipated in the circuit.

Total Power dissipated in a current carrying circuit is given as

P = i V

inserting the above values of the current and voltage in the above equation , we get

P = (2 A) (24 V)

P = (2 x 24) (AV)

P = 48 Watt                 (Since Ampere -Volt  = watt)
maybe you can divide the volts its twelve if you do that but itll show you how much to double it by

What characteristics of EM waves did you discover?

Answers

The characteristics of electromagnetic waves typically represent as follows:

  • There are changes in the electric and magnetic fields simultaneously so that both fields have maximum and minimum values ​​at the same time and place.
  • The direction of the electric field and the magnetic field are perpendicular to each other. The direction of both is perpendicular to the direction of the wave propagation.
  • The shape of electromagnetic waves is transverse waves.
  • It has general wave characteristics like polarization, reflection, refraction, interference, and diffraction.
  • The amount of the electric field (E) is directly proportional to the magnitude of the magnetic field, with the relationship E = cB.
  • The universal constant of the velocity of electromagnetic waves in a vacuum is \boxed{ \ c = 3 * 10^8 \ m/s. \ }
  • The speed at which electromagnetic waves propagate depends merely on the electrical and magnetic properties of the medium that it travels on.
  • Because electromagnetic waves do not contain an electric charge, they do not experience any possible deviation in the electric or magnetic fields.

Further explanation

  • Two physicists who contributed significantly to developing the concept of electromagnetic waves are Faraday and Maxwell around 1831-1864.
  • From the observations, Faraday suggested that changes in the magnetic field cause an electric charge to flow in the loop of wire, contributing in the emergence of an electric field.
  • Maxwell proposed a reverse process, which is a change in the electric field will generate a magnetic field.
  • As follows, according to Faraday's Law, changes in sinusoidal magnetic fields generate electric fields which also change sinusoidally.
  • Meantime, according to Maxwell's Hypothesis, changes in sinusoidal electric fields generate magnetic fields which also change sinusoidally.
  • Furthermore, there is a process of combining electric and magnetic fields that propagate in all directions called electromagnetic waves.

Answer: reflection

Refraction

Energy

Speed

Explanation:

Reflection results when em wave hits a plane surface and returns in the same angle it incident

Refraction is the change in velocity and direction of em wave as it crosses boundaries of different medium

The energy of em wave is evenly distributed in electric field and magnetic field

The speed of em wave is the same as 3×10^8

Which of the following is an acceptable description of the frequency of a transverse wave?

Answers

The correct answer for the question that is being presented above is this one: "A transverse wave is a disturbance in a medium (or lack there of as in light's case), where the disruption of the medium is perpendicular to the propagation of the wave. "
