What is a sound wave?

Answers

A sound wave is the pattern of disturbance caused by the movement of energy traveling through a medium (such as air, water, or any other liquid or solid matter) as it propagates away from the source of the sound. The source is some object that causes a vibration, such as a ringing telephone, or a person's vocal chords.

A light ray strikes a reflective plane surface at an angle of 65º with the surface.
Answer the following questions (show your work)
1) Determine the angle of incidence.
2)Determine the angle made by the incident and reflected rays.

Answers

Answer:

65degrees

130degrees

Explanation:

In reflection, the angle of incidence(i) is the same as the angle of reflection (r)

Given that

Angle of reflection is 65degrees

Hence

i=r = 65degrees

Angle that angle made by the incident and reflected rays = i+r = 65+65

Angle that angle made by the incident and reflected rays = i+r = 130degrees

A train starting from rest moves with a uniform acceleration of 0.2 ms-2 for 5 minutes. Calculate the final velocity and the distance travelled in this time.

Answers

Answer:

Final velocity = 60 m/s

Distance travelled = 9000 m

Explanation:

Applying,

For Final velocity,

v = u+at ............... Equation 1

Where v = final velocity, u = initial velocity, a = acceleration, t = time.

From the question,

Given: u = 0 m/s(at rest), a = 0.2 m/s², t = 5 minutes = (5×60) = 300 s

Substitute these values into equation 1

v = 0+0.2(300)

v = 60 m/s.

Also for distance,

Applying,

s = ut+1/2at²................ Equation 2

Where s = distance travelled.

subtitute thes values above into equation 2

s = (0×300)+(0.2×300²)/2

s = 9000 m

When do we say that work is done?​

Answers

Answer:

Work is said to be done when a force applied to an object moves that object. We can calculate work by multiplying the force by the movement of the object.

Please help me do this problem

Answers

Answer:

i) acceleration from B to D is 0, because the velocity is constant (stays the same)

ii) whatever units of distathat might be, we can calculate the number:

for 4 time-steps (2 to 6) the velocity is 6 per time step, that makes 24 distance units in these 4 time steps. it's the same the area underneath the graph.

there is also the vertical line from 0 to 2. we can calculate that distance like the area of a triangle with 2*6 / 2 = 6

the total distance from 0 to D is therefore 30

In Einstein’s analysis, a photon striking the surface of a conductor is absorbed by an electron. Which statement describes the set of energy transfers that could occur?
A. the electron receives either all or none of the photon's energy
B. The electron may receive any fraction of the photon's energy, including all or none of it
C. The electron may receive only certain quantized amounts of the photon's energy, including all or none of it

Answers

Answer:

the correct answer is A

Explanation:

In an Einstein-type analysis, the photon is absorbed, it loses all its energy, therefore the electron must receive all or none of the energy of the incident photon. In a type of inelastic shock.

Let's analyze the different answers

A) true. In photon it is completely absorbed or passes without interaction

B) False. The photon must change energy, but in this case there is no absorption of the photon

C) False. In the insistent analyzes, the quantization of the electron in discrete states is not mentioned.

Therefore the correct answer is A

Liana draws a diagram to show the direction of the electric force acting on a charged particle in a uniform electric field.

Which change would make the diagram correct?
A. Changing the charge to negative
B. Making the field lines point down
C. Changing the force to point right
D. Removing the force arrow

Answers

Answer:

changing the force to point right is the correct answer :)

The direction of the force acting on the field should be changed to point towards the right.

What is an electric field?

An electric field is referred to as the region where the influence of charge is felt. Thus, the force acts in the direction of the electric field when the field is uniform.

Having said that, it follows that the direction of the force acting on the field should be changed to point towards the right.

The volume of a gas is halved during an adiabatic compression that increases the pressure by a factor of 2.5. By what factor does the temperature increase?

Answers

Answer: 1.24

Explanation:

Given

Volume becomes half and pressure increases by a factor of 2.5

In adiabatic process [tex]PV^{\gamma}=\text{constant}\ \text{or}\ TV^{\gamma}=\text{constant}[/tex]

Finding out [tex]\gamma[/tex] first

[tex]\Rightarrow PV^{\gamma}=2.5P(0.5V)^{\gamma}\\\\\Rightarrow \left(\dfrac{V}{0.5V}\right)^{\gamma}=2.5\\\\\Rightarrow 2^{\gamma}=2.5\\\\\text{Taking log both side}\\\\\Rightarrow \gamma=\dfrac{\ln (2.5)}{\ln (2)}\\\\\Rightarrow \gamma=1.32[/tex]

Applying same principle for Temperature

[tex]\Rightarrow TV^{1.32-1}=T'(0.5V)^{1.32-1}\\\\\Rightarrow T'=(2)^{0.32}T\\\\\Rightarrow T'=1.24T[/tex]

Thus, the temperature increases by a factor of [tex]1.24[/tex]

The factor by which the temperature increases is; 1.24

How to find increase in temperature in an adiabatic process?

In thermodynamics, an adiabatic process is one that happens when there is zero heat transfer between the system and its environment. Thereafter, the internal energy change becomes the total work done by the system. The formula associated with this process for an ideal gas is;

[tex]PV^{\gamma }[/tex] = Constant

We are told that there is an increase in pressure by a factor of 2.5 and that the volume is halved. Thus, we will have;

[tex]PV^{\gamma} = 2.5P(0.5V)^{\gamma}[/tex]

This will be simplified to;

[tex](\frac{1}{0.5})^{\gamma} = 2.5[/tex]

⇒ [tex]\gamma = \frac{In2.5}{In 2}[/tex]

γ = 1.32

Now, If the volume expands in an adiabatic process, then the volume temperature relation is expressed as:

[tex]T_{1}V_{1}^{\gamma - 1 } = T_{2}V_{2}^{\gamma - 1 }[/tex]

[tex]T_{1}V_{1}^{1.32 - 1 } = T_{2}(0.5V_{1})^{1.32 - 1 }[/tex]

Simplifying this gives;

T₁ = 1.24T₂

A man walks 11m west then 12m south . What is the magnitude of his displacement?

Answers

The magnitude of man's displacement at the given initial position and final position is 16.28 km.

Displacement pf the man

The displacement of the man is the shortest distance between the final position and the initial position. It can also be described as the change in the position of the man.

The magnitude of the man's displacement is calculated as follows;

d² = 11² + 12²

d² = 265

d = √265

d = 16.28 km

Thus, the magnitude of man's displacement at the given initial position and final position is 16.28 km.
