Option C is wrong. Chemical and Nuclear energy are different. Chemical Energy is potential energy that can be converted to other forms, usually heat and light. This is energy when bonds form. The stronger the bond the more chemical energy that can be converted. Nuclear Energy is the energy that can be converted to other forms when there is a change in the nucleus of an atom from a) splitting of the nucleus b) fusing two nuclei to form a new nucleus. Nuclear energy can be both potential and kinetic.

The neutron is a subatomic particle that has no electric charge. It is found in the nucleus of every atom (except hydrogen). As the name suggests, it is neutral.

The proper formula for Copper Sulfate is CuSO4(H2O)x. Take note that the x here can range from 0 to 5. The thing about this type of compound is it is also known for its other older names. Some examples of its older names are bluestone, Roman vitriol, and blue vitriol. This is an ingredient that can be found in molluscicides. This is commonly used in order to kill different slugs and snails. This can also be added to certain types of fungicide which means that it will be able to kill some type of fungi. Take note that some fungi have already elevated which means that this will not have any effect on them anymore. This type of compound is also soluble in water.

The correct answer to this question is A. The bowling ball has more kinetic energy because it has a greater mass than the ping pong ball and greater distribution of mass. A ping pong ball is hollow, whereas the bowling ball's solid mass affects the inertia as it rolls. Had the bowling ball and the ping pong ball been dropped from the same height, at the same time, with the exact same force, they would hit the ground at the same time. However, when there is a slope involved, the mass and mass distribution of the balls impacts the outcome.

Sorry, John.. I think you misunderstood the answer choices... The correct answer is (B)... The gravitational force and acceleration due to gravity are derived via the Fg = G m1m2/r^2 equation... where mass and distance from the center of the object make a difference... D is wrong because.... The gravitational constant(G) is the same throughout the Universe (as we know it).. It is G= 6.67 x 10^-11 N m^2/kg^2 The accelerations due to gravity(g) are different on Earth(9.8 m/s^2)and Mars (3.8 m/s^2)

Both 2 & 4 should count as correct answers. Boyle's law does not state that at a constant temperature, if the volume of a container of gas is decreased, then the pressure of the gas will be increased nor does it state that if the volume of a container of gas is increased, then the pressure of the gas will be decreased. Instead it describes how, in an ideal gas at constant temperature, pressure and volume will be inversely proportional. This implies that both answers, 2 & 4, are correct.

Both answer 1 and answer 2 should count as correct. Charles's Law does not merely say that, at a constant pressure, if the temperature of a gas increases the volume increases nor does it merely say that, at a constant pressure, if the temperature of a gas decreases the volume decreases. Instead, it establishes a direct proportionality, at constant pressure, between temperature and volume. This implies the correctness of both answer 1 and of answer 2.
