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.
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.

Arturo dreams about travelling to faraway stars someday. He read that the closest star to Earth is Proxima Centauri, which is 4.25 light years away. He also read that the Law of Special Relativity says that the mass of an object increases as its speed increases. It approaches infinity as it approaches the speed of light. How does this most likely affect the goals of the United States space program?
Answer:
It will keep the goals from being comeplet when they wanted it to.

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

If an element has an atomic number of 25, then the atom will have
Question 1 options:
A. 25 protons
25 neutrons
B. 50 electrons
C.50 protons
Question 2 (1 point)
If you subtract the atomic number from the atomic mass number, you can find:
A. the number of neutrons
B. the number of protons
C. the number of electrons
D. the number of isotopes of that element
Question 3 (1 point)
Isotopes of an element differ in the number of
A. neutrons
electrons
B. nucleus
C. protons
Answer:
i have the list...
Explanation:
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

Sound waves transfer energy by the motion of particles
Sound waves can travel through space
Sounds waves are made by machines
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
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.

Four students are carrying out different laboratory procedures.
Piroja is mixing baking soda and vinegar to see if it reacts.
Jason is heating salt water over a burner until the water evaporates.
Kali is putting crushed ice and ice cubes on a table to see which melts first.
Francisco is separating iron filings from sand using a magnet.
Which experiment relies on convection?
Piroja’s experiment
Jason’s experiment
Kali’s experiment
Francisco’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.

A. Replace the diver with someone who has more mass.
B. Decrease the height of the diving board.
C. Increase the length of the diving board.
D. Increase the height of the diving board.
*If you do not know the answer, then DON'T respond. I will report you. Also, explanations are appreciated but if not then that's fine.
Answer:
B
Explanation:
If you decrease the height of the diving board, you will create less energy because you will build up less acceleration jumping from a lower height. Hope this helps ya!

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.
