How are force, mass, and inertia related? A. An object that requires a larger force to accelerate has a greater mass and a greater inertia. B. An object that requires a larger force to accelerate has a smaller mass and a greater inertia. C. An object that requires a smaller force to accelerate has a smaller mass and a greater inertia. D. An object that requires a smaller force to accelerate has a greater mass and a greater inertia.
Answers
An object that requires a larger force to accelerate has a greater mass and greater inertia. Hence, option A is correct.
What is inertia?A property of matter by which it remains at rest or in motion in the same straight line unless acted upon by some external force.
The more mass found in an object, the more inertia it contains and therefore the greater its tendency to resist change.
That is precisely why applying a net force on two objects of different masses will cause the lighter mass to accelerate more than the object that has a higher mass.
An object that requires a larger force to accelerate has a greater mass and greater inertia. Hence, option A is correct.

when a gas undergoes an isothermal process, there is
Answers
Answer:
no change in the temperature of the gas.
Explanation:
isothermal process of a gas, can result to compression of the gas or expansion of the gas at a constant temperature (ΔT = 0).
For isothermal gas expansion, work is done in reducing the pressure of the gas by increasing its volume at a constant temperature. The change in the internal energy of this process is zero (ΔU = 0).
For isothermal gas compression, work is done in decreasing the volume of the gas by increasing its pressure at a constant temperature. The change in the internal energy of this process is also zero (ΔU = 0).
Therefore, when a gas undergoes an isothermal process, there is no change in the temperature of the gas.

Hydrogen 1 + Lithium 7 yields 2 Helium 4 plus energy
you have merged hydrogen 1 with Lithium 7 to produce a temporary berylium8, so it is fusion, because you are fusing the particles together.
the energy of the impact of the hydrogen on the lithium
causes the temporary berylium 8 to split into 2 helium atoms, so it is then fission, because you are splitting an atom of berylium8.
the mass of the reactants and products are not equal, because some of the energy comes from conversion of the reactant mass to energy by E=mcc
The number of reactant particles does equal the number of product particles, bute answer says ONLY which is not correct
In the given reaction, The mass of the products is exactly equal to the reactants. However this a radioactive process where, lithium and hydrogen react together forming two helium nuclei.
What is mass conservation?According to the law of conservation of mass, mass can neither be created nor be destroyed. Thus the total mass of a system is conserved. In a closed system the mass cannot be lost.
For a chemical reaction, new products are formed by regrouping of atoms from the reactants where no new atom is produced not any lost. Hence, the total mass in the reactant side will be equal to the total mass in the product side.
In the given reaction the number of particles are equal in both side as well mass too equal in both side. The total mass in reactant side and product side is 8.

How can you increase the strength of the magnetic force on an object like a paper clip?
Answers
Answer:
"Iron bar magnets Fill a bowl or pan with some water. Find something that will float on the water. Lay the magnet on top of this object. The magnet will twirl in the water until it comes to rest pointing exactly north and south due to the magnetic force of the North Pole."-- science.howstuffworks.com. Or you could just increase the surface area.
Explanation:
The strength of the magnet force is maximum at the poles and minimum at the centre. A magnet can exerts a magnetic force on the other magnets as well. Here by using the soft iron bar as the magnet, the strength of the magnetic force on an object can be increased.
A magnetic force is defined as the force that a magnet exerts on certain materials like iron, steel, nickel, etc. This type of force is a non-contact force because it can act from a distance.
By using iron bar magnet or by increasing the numbers of turns of the coil can pick up more paper clips.

Answers
Answer:
The answer is Yes
Explanation:
I jus got it right no cap
Your classmate says that the farther the two atoms are apart in a bond, the larger the dipole moment will be, this statement is correct.
What is bond ?An enduring attraction between atoms or ions known as a chemical bond is what allows molecules and crystals to form. The bond may be created by the sharing of electrons in covalent bonds or by the electrostatic attraction of two oppositely charged ions, as in ionic bonds.
Chemical bonds are formed when the atoms in a compound's molecule are brought together and kept together by a powerful combining force. Ionic and covalent bonds are the two different kinds of chemical bonding.
Atoms trade or exchange valence electrons to create bonds. The electrons at an atom's outermost energy level, known as valence electrons, have the potential to interact chemically. All chemical bonds are built on valence electrons.
Thus, the farther the two atoms are apart in a bond, the larger the dipole moment will be, this statement is correct.

Answers
Answer:
107.5252955kPa or 108kPa
Explanation:
Use Gay Lussac's Law, P1/T1 = P2/T2
Manipulate the equation: P2 = P1*T2/T1
Change C to K: 35.6C = 308.75K and 17.3 = 290.45K
Input the values: P2 = (114.3kPa)(290.45K)/308.75K
P2= 107.5252955kPa
You probably want to round to 3 sig figs, so 108kPa
