What is your REASONING for this CLAIM? EXPLAIN WHY your claim is true.
You MUST USE the terms KINETIC ENERGY and ENERGY TRANSFER in your response.

Answer:

IV: speed of the fan

DV: time of cup ascent

Explanation:

Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. As the speed of the fan increases, so does the kinetic energy, then it transfers energy to the Cup ascent.

Ms. Cristell, a seventh-grade teacher at OHVA, made the following statement, “Sound energy, also known as acoustic energy, is a type of mechanical energy.” Why are sound waves considered a type of mechanical energy?
Question 8 options:

Sound waves can travel through a solid

Sound waves transfer energy by the motion of particles

Sound waves can travel through space

Sounds waves are made by machines

Practice Activity:
.
In this experiment, the team will need to set up three different cups and label them as A,
B, and C. All three cups will get the same amount of water added to them. In order to
see how kinetic energy is transferred, the team needs to measure the initial
temperatures of each cup and record that in the data table, and then add different
amounts of ice to cups B and C. The mass of each amount of ice will be recorded in the
data table. After each ice cube melts, the team will record the temperature of the water
in each cup.
o The change in temperature will tell the team how much kinetic energy was
transferred from the water to the ice.
Think about how one can work effectively in a team to set the experiment up.
gather data, and analyze the data.

Please help!!!! If something is shot straight up in the air at a speed of 70 m/s, how much time before it will hit the ground? (when I calculated it I got 14 is it right?) My following question is if the object from number 2 is shot up (70m/s) in the air how high will it get?

What is going on in this situation?

What happens at the dew point?
Answer: Clouds are formed

What causes rain?
Answer: dust particles can no longer support water droplets

The return of water vapor to the liquid form is called:
Answer: condensation

Water vapor is produced by the process of:
Answer: evaporation

What happens to air when it is heated by the sun?
Answer: It rises

Which event demonstrates electromagnetic waves transferring energy?
An explosion causing a window to break
An astronaut tapping two rocks together
A person diving in a swimming pool
Sun heating a car sitting in a parking lot

Read the passage.


Gerald lives in a town that has experienced a population boom in recent years. Until last year, all of the town’s major decisions and policies were made at town meetings. All of the town’s residents were invited to these meetings, and every resident was allowed to debate and vote on the decisions that were made. Last year, due to the town’s expanding population, the townspeople voted to end the town meetings and to instead elect town council members who would be responsible for hearing citizens’ concerns and attending regular council meetings. Major decisions and policies for the town are now made only by these elected council members at town council meetings.
THE QUESTION- Which type of government was in place in Gerald’s town before the town council was established?
Answers:

#1 a dictatorship

#2 a direct democracy

#3 an absolute monarchy

#4 a representative democracy

A mass of 80 g of KNO3 is dissolved in 100 g of water at 50 ºC. The solution is heated to 70ºC. How many more grams of potassium nitrate must be added to make the solution saturated? Explain your reasoning

Officials are looking into three different ski accidents. The accidents happened when three skiers (all with the same mass) were skiing across the flat, snowy ground. They were each bumped by another skier, but not all from the same direction. These skiers changed speed as a result of being bumped. Use the information in the diagram to answer.

Which skier(s) experienced the strongest force when bumped? How do you know?


a
The skiers in the yellow and purple sweaters; both gained the same force as they sped up, but the skier in the red sweater lost force and slowed down.

b
The skier in the yellow sweater experienced the strongest force because he has the fastest ending speed.


c
All three skiers experienced the same strong force because they changed speed by the same amount.


d
The skier in the red sweater because it takes a stronger force to slow something down than to speed it up.

A student poured 500 mL of milk into one flask and 500 mL of water into another flask.
Which of the following conclusions can the student make about the physical properties
of these two liquids just by looking at the flasks?
A: The density of milk is greater than that of water.
B: Milk has a greater mass than water.
C: Milk and water are soluble fluids.

Look at the graph pic and answer the question correctly!

If I had a boat, and it had a higher density than water, would it matter only the density thats keeping the boat up or the shape too?

please someone help me? if you have a good answer I will gave U a brainlest :)
look at the foto and help me
if you can write at leat 2 it will help me so much :3
