Answer:
Inversely proportional
Explanation:
The amplitude and frequency of a wave have an inverse connection, with the amplitude being inversely proportional to the frequency. As the frequency rises, the amplitude falls. As the frequency decreases, the amplitude increases.

A student has begun training for tryouts for cross country by running a two mile loop through
her neighborhood every evening. Part of the run is a very steep hill. One evening, the
student is running down the hill at a very quick pace when she notices a dog lying in the
middle of her path. To avoid hitting the dog, she tries to stop but has difficulty. With
effort, she is able to stop right before running into to the dog.
Explain why it was so difficult for the student to stop. In your response, be sure to
include:
○ the role of Newton’s first law in making it difficult for the student to stop.
○ the correct use of the term inertia.
○ why some objects in motion have more inertia than others.
Be sure to consider the completeness of your response, supporting details, and accurate
use of terms

What best describes the pitch that juan hears? the pitch remains constant as the ambulance moves toward and then away from juan. the pitch increases and decreases in a repeated pattern as the ambulance passes juan. the pitch drops to a lower pitch once the ambulance passes by juan. the pitch increases to a higher pitch once the ambulance passes by juan.
The correct answer is "the pitch drops to a lower pitch once the ambulance passes by Juan".
What is the Doppler effect?When there is relative motion between the source and the listener, the Doppler effect causes the frequency to rise or decrease. The frequency determines the pitch. When the frequency rises, the pitch rises with it.
When the source and the listener get closer to each other, the frequency rises. There is a reduction in frequency as the source and listener move away from each other.
Juan is standing on the street in the provided situation. When an ambulance approaches Juan and then passes by, the pitch dips to a lower level.
Hence "The pitch decreases to a lower pitch once the ambulance passes by Juan," is the right answer.

(i) Calculate the average friction force provided by the brakes.
answer
the friction force provided by the brakes is 30000 N.
What is friction force?Friction force is the force that opposes the motion between two bodies in contact.
To calculate the average friction force provided by the brakes, we apply the formula below.
Formula:
K.E = F'd............. Equation 1Where:
K.E = Kinetic energy of the trainF' = Friction force provided by the brakesd = distanceMake F' the subject of the equation
F' = K.E/d............ Equation 2From the question,
Given:
K.E = 8.1×10⁶d = 270 mSubstitute these values into equation 2
F' = (8.1 ×10⁶)/270F' = 30000 NHence, the friction force provided by the brakes is 30000 N

The lava lamp has a light bulb as a heat source at its base. The lamp contains a colored, waxy fluid that can be observed moving in clumps through a clear liquid. A lava lamp filled with orange blobs lit from below. As the clump of colored fluid at the bottom of the lava lamp reaches the top, which has increased? its density its temperature the kinetic energy of its molecules the space between its molecules.
As the clump of colored fluid at the bottom of the lava lamp reaches the top, Its temperature increases. Temperature directs to the hotness or coldness of a body.
What is temperature?Temperature directs to the hotness or coldness of a body. In clear terms, it is the method of finding the kinetic energy of particles within an entity. Faster the motion of particles more the temperature.
Temperature is essential in all areas of Science right from Physics to Geology and also it is important in most parts of our everyday life.
The clump of colorful fluid at the bottom of the lava lamp rises to the top because the clump, as the heavier liquid, absorbs heat and expands, becoming less dense and rising.
Due to this the temperature is increasing.Hence As the clump of colored fluid at the bottom of the lava lamp reaches the top, Its temperature increases

A 600 W electric heater is connected to a 120 V source. Calculate its current.
Question :-
A 600 Watt electric heater is connected to a 120 Volt source . Calculate its Current .Answer :-
Current is 5 Ampere .Explanation :-
As per the provided information in the given question, we have been given that the Power is 600 Watt , Voltage is given as 120 Volt . And, we have been asked to calculate the Current .
Now, for calculating the Current , we will use the Formula :-
[tex] \bigstar \: \: \boxed{ \sf{ \: Current \: \: = \: \: \dfrac{ \: Power \: }{Voltage} \: }} \\ [/tex]
Therefore, by Substituting the given values in the above Formula :-

The star Aldebaran is a red giant star in the constellation Taurus, the Bull. Aldebaran is the eye of the bull and is about 65 light years away. What would happen if Aldebaran were to explode tonight
If Aldebaran were to explode tonight then we will be able to see this explosion on the Earth in approximately 65 years. A light-year is a distance that light travels in one (1) year.
What is a light-year?A light-year can be defined as a unit equal to the distance that light needs to travels in one (1) year on the Earth.
One light-year can be considered as a unit that equates to approx. 9.7 trillion kilometers (km) or 5.9 trillion miles.
In consequence, a light-year is a distance unit instead of a unit of time, and this unit was developed by Otto Ule.

16. A pug puppy is sitting on a skateboard. The pug has a mass of 2.4 kg, and the skateboard has a mass
of 1.3 kg. Assuming the pug stays on the skateboard, what force would give the pug and skateboard an
acceleration of 3.2 m/s?? You may ignore friction. Be sure to follow significant digit rules.
Answer:
12 N
Explanation:
Use Newton's second law:
∑F = ma
F = (2.4 kg + 1.3 kg) (3.2 m/s²)
F = 11.84 N
Rounded to two significant figures, the force is 12 N.
A 120V Microwave uses 8A of current. It runs for 15 hours over the course of a month. If electrical energy costs $0. 11/KWh, what does it cost to run the microwave for the month
Answer:
1 kw-hr = 1000 w * 3600 sec = 3.6E6 Joules
E = P t = 120 J/C * 8 C/sec * 3600 sec /hr * 15 hr = 5.18E7Joules
where E is energy used by microwave
5.18E7 / 3.6E6 * .11 = $1.58 cost to run for 15 hrs
