Answer:
B's acceleration is half that of A
Explanation:
The force equation is;
Force = mass × acceleration
According to Newton's second law of motion, which explains the relationship between acceleration and mass of an object, an inverse relationship exists between the mass and the acceleration. For the same amount of force, an increase in mass (m) means a constant decrease in acceleration (a) of the object. In other words, if the mass of an object increases by two times, the acceleration will decrease by two times.
In this case involving objects A and B which has the same amount of force applied, object B has TWICE the mass of A. Using Newton's second law, this means that object B's ACCELERATION WILL BE HALF OF THAT OF OBJECT A.
Answer:
Explanation:
Percent composition is percentage by the mass of element present in the compound.
Given , Mass of sulfur= 32.1 amu
Mass of oxygen = 16.0 amu
Mass of sulfur trioxide 
= 32.1 amu + 3*16.0 amu = 80.1 amu

Explanation:
The average distance a gas particle travels between collisions (with the wall or another particle is called the mean free path.
According to the kinetic theory of gases, the particles of a gas (atoms or molecules) have the highest kinetic energy and travel at high speeds. At standard temperature and pressure, a gas particle can reach speeds of about 470m/s.
Despite the high speeds gas particles travel, it still takes a while for the fragrance of an opened perfume to diffuse to the other end of the room. This is because when moving, the molecules do not have a free path. They constantly collide with other particles and the walls of the container and change direction randomly. The average distance a single particle can travel without colliding with other particles, or the wall of the container is called the mean free path.

Answer:
Energy is absorbed, and an emission line is produced.
Explanation:
Electrons are present and revolving continuously in the orbits that are present around the nucleus. The energy of electron are fixed and unable to move to other orbits due to the strong attractive force of the proton which is present in the nucleus of the atom. If the electron wants to jump from the first energy level to the second energy level, so the electron has to absorb enough energy which can overcome the attractive force of proton.
