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.

true or false​

Answers

True. Being an electrical engineer, you learn very quickly that current will take All paths of resistance. But, the higher the resistance the lower the voltage. So, if a high resistance is shorted and the current flows through the short, there will be some small voltage across it, so some small amount of current will still flow through the high resistance.

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

Answers

Hi um i think its At 30 ° C your welcome

50 g more potassium nitrate must be added to make the solution saturated at 70 °C.

Solubility:

It is the degree of dissolved substance at room temperature or 25 °C per  [tex]\bold {g/100\ cm^3}[/tex].

Saturation:

If no more solute or solid substance is dissolved in the solution, then the solution is called saturated.

Saturation increase with the increase in temperature because the kinetic energy of the particles is increased.

Therefore, 50 g more potassium nitrate must be added to make the solution saturated at 70 °C.

You MUST USE the terms KINETIC ENERGY and ENERGY TRANSFER in your response.

Answers

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.

Kinetic energy is energy in motion (movement). Energy transfer is the process by which energy is relocated from one system to another, for example, through the transfer of heat, work or mass transfer. (Not really sure what the question this)

Question: 1 atomic number 25 would have twenty-five protons and twenty-five electrons.

Question 2: atomic mass - atomic number = number of protons + number of neutrons - number of protons we get the number of neutrons present in an atom when we subtract the atomic number from the atomic mass.

Question 3: Different isotopes of an element have the same number of protons in the nucleus

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.

Answers

The second one I think I forgot I did this question before but maybe yellow

When the skiers were bumped by other skiers, all three skiers experienced the same strong force because their speed changed by the same amount. Therefore, option (C) is correct.

How can the motion of an already moving object change?

The motion of an object is the change in position of a body with respect to its surrounding within a given interval of time.  If the position changes with time, an object is said to be in motion, with reference to a fixed frame.

The change in motion of an object is equivalent to a change in velocity. A change in velocity can be applied so that there will be acceleration. The force causes a change in the motion of an object and it produces acceleration too.

The change in the speed of the red skier after the bumped = 10 -4 = 6m/s

The change in the speed of the yellow skier after the bump:

[tex]= 6- 12 = - 6m/s[/tex]

The change in the speed of the purple skier after the bump:

[tex]= 0-6 = - 6m/s[/tex]

As the magnitude of change in the speed of all three skiers is the same so they experience the same force.

Answers

B. Jason’s experiment

Jason’s experiment of  heating salt water over a burner until the water evaporates relies on convection.

What is convection?

Convection is single- or multiphase fluid flow that develops on its own as a result of the interaction between a fluid's body forces—most frequently gravity and density—and material property heterogeneity.

Convection caused by the effects of thermal expansion and buoyancy might be assumed when the cause of the convection is unknown. Convection may also occur in mixes or soft materials where particles can move.

Convective flow can be either transitory (as when an oil and water multiphase combination separates) or steady state. Convection may result from electromagnetic, gravitational, or fictitious body forces. The composition of the Earth's atmosphere, seas, and mantle is influenced by heat transfer through natural convection.

Hence, heating salt water over a burner until the water evaporates relies on convection.

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.
