Aplastic ball attached to a spring moves in simple harmonic motion. the amplitude of the ball's motion is 11.0 cm, and the spring constant is 6.00 n/m. when the ball is halfway between its equilibrium position and its maximum displacement from equilibrium, its speed is 19.5 cm/s. (a) what is the mass of the ball (in kg)? what is the total energy of the spring-mass system in terms of amplitude? how is it related to the kinetic and potential energies? what is the position of the ball in terms of amplitude? kg what is the period of oscillation (in s)? how is the period related to the mass and spring constant? s what is the maximum acceleration of the ball? (enter the magnitude in m/s.) (b) (c) m/s2
answer: the correct options are (c)(d) and (e).
molecules is defined as group of two or more numbers of atoms of same or different elements. for example: etc.
is a molecule made up of one magnesium and two chlorine atoms.
nacl is molecule made up of one sodium and one chlorine atom
is molecule made up of three carbon atoms and eight hydrogen atoms.
hence, the correct options are (c)(d) and (e).
radius of sphere
the distance between the centers of the two spheres is
the charge of the sphere
the magnitude of the repulsive force between the charges pushing them a part is
using coulomb law
hence, this is the required solution.
option c - carbon dioxide and water
the chemical equation reaction of methane (ch4) and oxygen gas (o2) to form carbon dioxide (co2) and water (h2o).
ch4 + 2o2 → co2 + 2h2o.
in this equation, carbon dioxide and water are products. products are substances which are formed after a chemical reaction so in this case carbon dioxide and water are formed as a result after a chemical reaction. therefore, these are products of reaction of methane and oxygen gas.
