Make an observation about the average height of the beanbag. How does it compare with your calculated kinetic energies for each speed? Does the height of the beanbag increase in equal increments with each step up in speed? Record these qualitative observations in Table B.
Answers
Answer: The kinetic energy in the solid and liquid phases is the same. The kinetic energy of the substance's particles will depend on the volume of the substance. The particles have less kinetic energy in the liquid phase than they do in the gas phase. They vibrate so quickly that the particles ionize and become plasma.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
Answers
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

What we eat, and how we move our bodies, effects our blood. How does that end up affecting our other organs in the body
Answers
Answer:
The digestive system converts the foods we eat into their simplest forms, like glucose (sugars), amino acids (that make up protein) or fatty acids (that make up fats). The broken-down food is then absorbed into the bloodstream from the small intestine and the nutrients are carried to each cell in the body.
Answer:
The digestive system is made up of the gastrointestinal tract—also called the GI tract or digestive tract—and the liver, pancreas, and gallbladder. The GI tract is a series of hollow organs joined in a long, twisting tube from the mouth to the anus. The hollow organs that make up the GI tract are the mouth, esophagus, stomach, small intestine, large intestine, and anus. The liver, pancreas, and gallbladder are the solid organs of the digestive system.
The small intestine has three parts. The first part is called the duodenum. The jejunum is in the middle and the ileum is at the end. The large intestine includes the appendix, cecum, colon, and rectum. The appendix is a finger-shaped pouch attached to the cecum. The cecum is the first part of the large intestine. The colon is next. The rectum is the end of the large intestine.

Answers
7. False, an object with more mass has more/less gravitational force than an object with a smaller mass. Objects that are closer together have more/less of a gravitational force between them than objects that are further apart. The more separation two objects have, the more the force between them decreases.
8. True, objects that are closer together have more/less of a gravitational force between them than objects that are further apart. The more separation two objects have, the more the force between them decreases. When mass 1 increases the force between the objects increases.
9. False, Jupiter, the fifth planet from the Sun, has the strongest gravitational pull because it's the biggest and most massive.

Based on evidence from Sim, when two substances were combined they did not change into different substances.
Here the word Sim is used to describe the process simulation. Simulation is defined as when two substances combined they do not change into different substances.
They just combine together and form a new substance.
Let us understand it as the first substance is liquid and the second substance is solid then when we combine both of them they form a new mixture but do not change their property.
The mixture is still liquid but it also has some properties of solid substance.

The substances did not change into different substances.
Based on the information provided in the question, there is no evidence or indication of any chemical reaction or change in the substances when they were combined in the cup. The question does not mention any observations or effects that would suggest a chemical transformation.
If there were a chemical reaction or change, it would typically be accompanied by observable signs such as color change, gas production, temperature change, or formation of a precipitate. However, since the question does not provide any evidence or observations of such changes, we can conclude that the substances did not undergo any chemical transformation when combined.
It is important to note that without additional information or details about the substances and their behavior, it is not possible to make definitive conclusions. However, based on the given information, the most reasonable conclusion is that the substances remained unchanged when combined in the cup.

Answer: He needs to hit the ball with less force.
Explanation:
hope this helps
2. Based off the answer to the first question, by hitting the ping pong ball, momentum is transferred from the boy to the ball. Causing the ball to have more velocity/speed and gain more momentum.
3. Momentum before = momentum after
Every time the ball hits the table, some momentum transfers from the ball to the table. Every time the player hits the ball, some momentum transfers from the player to the ball. This allows the player to continue playing ping pong as the ball always has momentum.

1156 g/L
= ________ kg/mL
Answers
The Answer is 0.001156.
1156 g/L = 1.156 kg/L
Since 1 L is equal to 1000 mL, we can convert kg/L to kg/mL by dividing by 1000:
1.156 kg/L = 1.156/1000 kg/mL
1.156/1000 kg/mL = 0.001156 kg/mL
Therefore, 1156 g/L is equal to 0.001156 kg/mL.

Explanation: HOPE THIS HELPS!!!!When the speed of the bottle is 2 m/s, the KE is kg m2/s2. When the speed of the bottle is 3 m/s, the KE is kg m2/s2. When the speed of the bottle is 4 m/s, the KE is kg m2/s2. When the speed of the bottle is 5 m/s, the KE is kg m2/s2. When the speed of the bottle is 6 m/s, the KE is kg m2/s2.
instructions
In this part of the experiment, you will be changing the speed of the bottle by dropping it from different heights. You will use the same mass, 0.250 kg, for each trial, so record this mass in Table B for each velocity. Then, calculate the expected kinetic energy (KE) at each velocity. Use the formula KE = mv2,
where m is the mass and v is the speed. Record your calculations in Table B of your Student Guide.
Answers
Answer:
Based on the given instructions, you need to calculate the expected kinetic energy (KE) at each velocity using the formula KE = mv^2, where m is the mass and v is the speed. The mass is given as 0.250 kg.
Table B: Calculation of Kinetic Energy (KE)
Table B: Calculation of Kinetic Energy (KE)
Speed (m/s)Mass (kg)KE (kg m^2/s^2)20.2500.50030.2500.75040.2501.00050.2501.25060.2501.500
To calculate the kinetic energy at each velocity, multiply the mass (0.250 kg) by the square of the velocity.
For example, when the speed of the bottle is 2 m/s: KE = (0.250 kg) * (2 m/s)^2 = 0.250 kg * 4 m^2/s^2 = 1.000 kg m^2/s^2
Perform similar calculations for the other velocities and record the results in Table B.
Answer:
Explanation:mass of the bottle in each case is M = 0.250 kg
now as per given speeds we can use the formula of kinetic energy to find it
1) when speed is 2 m/s
kinetic energy is given as
2) when speed is 3 m/s
kinetic energy is given as
3) when speed is 4 m/s
kinetic energy is given as
4) when speed is 5 m/s
