What happens to the motion of an object if forces acting on the object are equal and balanced?

A. The object begins to move

B. The object begins to slow down

C. The motion of the object does not change

Answers

Answer 1

Answer:

When the forces acting on an object have equal strength and act in opposite directions, they are balanced. These forces cancel out one another, and the motion of the object they are acting on remains unchanged. The object may change its speed (speed up or slow down), or it may change its direction.

So I think its C

You see this is because if the forces were different the object would either speed up or slow down but in this case the forces are equal so the motion of the object does not change.

Number 1. A, two in the first energy level, six in the second energy level.

Energy levels are arranged in increasing order of magnitude in accordance with the Bohr model.

The correct sequence of answers is as follows;

1) two in the first energy level, six in the second energy level

2) The electron has a negative charge and is found outside of the nucleus.

3) Subtract the atomic number from the mass number.

4) the number of protons

An atom contains a nucleus and electrons arranged in energy levels outside the nucleus. Each energy level is filled with electrons.

The first energy level contains only two electrons, subsequent energy levels contain a maximum of eight electrons.

The proton is positively charged, the neutron has no charge and the electron is negatively charged. The proton and neutron are found inside the nucleus while the electrons are negatively charged and found outside the nucleus.

The mass number is the sum of the number of protons and neutrons. hence the number of neutrons is the difference between the mass number and the number of protons.

The number of protons in an atom is its atomic number.

Write a summary of what you have learned about how incoming forces and outgoing forces are related (newton's cradle)

Answers

Newton's Cradle is a classic physics demonstration that illustrates the principles of conservation of momentum and energy, as well as the relationship between incoming and outgoing forces. The device consists of a series of equally spaced, suspended metal balls (typically five) that are aligned in a horizontal row. When one ball is lifted and released, it strikes the next ball in line, causing a transfer of force through the remaining balls, ultimately resulting in the last ball swinging outward. This process repeats as the balls continue to collide.

The relationship between incoming and outgoing forces in Newton's Cradle can be understood through the following concepts:

Conservation of Momentum: In a closed system with no external forces, the total momentum before a collision is equal to the total momentum after the collision. In Newton's Cradle, the momentum of the incoming ball is transferred through the stationary balls and eventually to the last ball, which swings outward with a momentum equal to the initial ball's momentum.
Conservation of Energy: Similarly, the total mechanical energy (kinetic and potential) in a closed system remains constant. In the context of Newton's Cradle, the kinetic energy of the incoming ball is transferred through the stationary balls, and eventually to the last ball, which swings outward with kinetic energy equal to that of the incoming ball. Potential energy is also involved as the balls swing and momentarily come to rest at their highest points.
Elastic Collisions: Newton's Cradle demonstrates nearly perfect elastic collisions, wherein both momentum and kinetic energy are conserved. In reality, some energy is lost to heat and sound, making the collisions slightly inelastic. However, the demonstration is still a useful approximation for understanding the transfer of forces.
Force Transfer: The incoming force exerted by the first ball is transmitted through the intervening balls to the last ball without causing any significant movement of the middle balls. This occurs because the balls are very close together and the time taken for the force to be transferred is minimal, allowing the middle balls to remain nearly stationary.
In summary, Newton's Cradle demonstrates the relationship between incoming and outgoing forces through the principles of conservation of momentum and energy, elastic collisions, and force transfer. The device provides a clear visual representation of these fundamental concepts in physics.

Newton's Cradle is a classic physics demonstration that illustrates the conservation of momentum and energy. The cradle consists of a row of suspended metal spheres that are free to swing back and forth. When one of the spheres is lifted and released, it swings down and collides with the next sphere in the row. This collision causes the first sphere to come to a stop and transfers its momentum and energy to the second sphere, which in turn transfers it to the third sphere, and so on. The incoming force from the first sphere is transferred through the chain of spheres as outgoing forces, causing the last sphere to swing upward to the same height as the first. The total momentum and energy of the system remain constant throughout the process, demonstrating the principle of conservation of momentum and energy.

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.

the correct answer is A 4.8 mL

Develop models bonds can be placed on a scale that ranges from 100% ionic to 100% covalent. Use what you know about the types of bonds that specific elements tend to form to place each of the following compounds in the correct location on the scale: CO2, N2 , NaF, H2O

Answers

Answer:

Bonds can be placed on a scale that ranges from 100% ionic to 100% covalent.

CO2: CO2 is a covalent compound, with each carbon atom sharing electrons with two oxygen atoms. Therefore, it can be placed closer to the 100% covalent end of the scale.

N2: N2 is a covalent compound, with each nitrogen atom sharing electrons with another nitrogen atom. Therefore, it can be placed closer to the 100% covalent end of the scale.

NaF: NaF is an ionic compound, consisting of a sodium cation (Na+) and a fluoride anion (F-). Therefore, it can be placed closer to the 100% ionic end of the scale.

H2O: H2O is a polar covalent compound, with the hydrogen atoms sharing electrons with the oxygen atom, but the electrons are not shared equally, therefore the oxygen atom has a partial negative charge and hydrogen atoms have a partial positive charge. Therefore, it can be placed closer to the middle of the scale, between ionic and covalent.

Overall, the scale can be represented as follows:

100% Ionic <-------> NaF <-------> H2O <-------> CO2 <-------> N2 <-------> 100% Covalent

I’ll give the definitions for half of them ( 2 ) CO2 is Carbon dioxide and H20 is the scientific word for Water/ Aqua

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)

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
