Hotel rooms in Smalltown go for $100, and 1,000 rooms are rented on atypical day.a. To raise revenue, the mayor decides to charge hotels a tax of $10 perrented room. After the tax is imposed, the going rate for hotel roomsrises to $108, and the number of rooms rented falls to 900. Calculate theamount of revenue this tax raises for Smalltown and the deadweightloss of the tax. (Hint: The area of a triangle is l/2Xbase X height.)h. The mayor now doubles the tax to $20. The price rises to $116, andthe number of rooms rented falls to 800. Calculate tax revenue anddeadweight loss with this larger tax. Are they double, more thandouble, or less than double? Explain.

think the sound frequencies that dogs can

hear compare to the frequencies that humans

can hear?

**Dogs** can hear **sounds** at higher frequencies than humans. The range of sound frequencies that dogs can hear is approximately 40 Hz to 60,000 Hz, while the range for humans is 20 Hz to 20,000 Hz. This means that dogs can hear ultrasonic sounds that are beyond the range of human hearing.

In terms of physics, **sound** is a vibration that travels through a transmission medium like a gas, liquid, or solid as an acoustic **wave**.

**Sound** is the reception of these waves and the brain's perception of them in terms of human physiology and psychology. **Dogs** have the ability to hear ultrasonic sounds that are audible only to them.

A. sideways

B. up and down

C. back and forth

D. all of the above

**Answer: D i am pretty sure**

**Explanation:**

**Answer:**

all

**Explanation:**

To solve this problem it is necessary to apply the concepts related to Newton's second law and the equations of motion description for acceleration.

From the perspective of acceleration we have to describe it as

Where,

= Velocity

= time

At the same time by the Newton's second law we have that

F = ma

Where,

m = mass

a = Acceleration

Replacing the value of acceleration we have

Our values are given as,

Replacing we have,

Therefore the magnitude of the average force exerted on the ball by the club is 744.11N

7500 J were released in the explosion, how much kinetic energydid

each piece acquire?

**Answer:**

4500 J and 3000 J

**Explanation:**

According to conservation of momentum

Given that m_2 = 1.5 m_1 , so

the kinetic energy of each piece is

substituting the value of V1 in the above equation

Given that

K_1 + k_2 = 7500 J

1.5 K_2 + K_2 = 7500

K_2 = 7500 / 2.5

= 3000 J

this is the KE of heavier mass

K_1 = 7500 - 3000 = 4500 J

this is the KE of lighter mass

The question is about finding the kinetic energy acquired by each of two pieces of an object following an internal explosion, using principles of conservation of energy and momentum in physics.

The student has asked about an **internal explosion** that breaks an object into two pieces with different masses, releasing a certain amount of **kinetic energy** in the process. This question involves applying the principle of conservation of energy and momentum to find the kinetic energy acquired by each piece post-explosion.

Assuming piece 1 has a mass of *m* and piece 2 has a mass of 1.5*m*, the total mass of the system is 2.5*m*. Since 7500 J of energy was released in the explosion, to find the kinetic energy of each piece, we can use the fact that the total kinetic energy is equal to the energy released during the explosion. Let the kinetic energy of the smaller piece be *K**1* and of the larger piece be *K**2*. Because the object was initially at rest and momentum must be conserved, the momenta of the two pieces must be equal and opposite. This relationship allows us to derive the ratio of the kinetic energies. We can solve for *K**1* and *K**2* proportionally. Finally, because the kinetic energy is a scalar quantity, adding the kinetic energies of the two pieces will equal the total energy released.

**Answer:**

The reflection of light can be roughly categorized into two types of reflection: specular reflection is defined as light reflected from a smooth surface at a definite angle, and diffuse reflection, which is produced by rough surfaces that tend to reflect light in all directions

mark as brainliest plz

**Explanation:**

Reflection is the process of light bouncing off a surface and changing its direction. There are two types of reflection: specular reflection and diffuse reflection.

Reflection is the process of light bouncing off a surface and changing its direction. There are two types of reflection: specular reflection and diffuse reflection.

Specular reflection occurs when light reflects off a smooth surface, such as a mirror, at a specific angle.

Diffuse reflection occurs when light reflects off a rough surface, such as paper or clothing, and scatters in many different directions.

40 N/C. e. 60 N/C.

**Answer:**

E = 20 N/C

**Explanation:**

Given that,

Charge, q = 2 C

Force experience, F = 40 N

We need to find the electric field at that location.

The electric field in terms of electric force is given by :

F = qE

Where

E is the electric field

**So, the electric field at that location is 20 N/C.**
