Answer:
C
Explanation:
The change in momentum of x has to be the opposite of the change in momentum of Y because the momentum is just transferred from one to another. But I'm still trying to figure it out how to calculate.
Answer:
The atoms ,molecules, or compound present at the start of a chemical reaction that parcitipate in the reaction are <u><em>the reactants.</em></u>
Explanation:
The chemical reaction is the way in which one substance reacts against another. So, a chemical reaction consists of the transformation of some substances into others, that is, the process of arranging atoms and bonds when chemical substances come into contact.
In a chemical reaction, the initial substances are called reactants, while the new substances obtained are called products.
So, <u><em>the atoms ,molecules, or compound present at the start of a chemical reaction that parcitipate in the reaction are the reactants.</em></u>
To solve this problem we could apply the concepts given by the conservation of Energy.
During the launch given in terms of kinetic energy and reaching the maximum point of the object, the potential energy of the body is conserved. However, part of all this energy is lost due to the work done by the friction force due to friction with the air, therefore
The potential and kinetic energy are conserved and are the same PE = KE and this value is equivalent to 100J, therefore
The kinetic energy will ultimately be less than 100J, so the correct answer is C.
Answer:
Frequency (f) can be defined as the number of waves or crests or number of troughs that pass a point per unit second. It can be measured in Hertz (Hz) or 1/s.
Answer:
Teratogens
Explanation:
Teratogens are substances or other factors that can cause congenital abnormalities, which are also called birth defects. Usually these abnormalities arise in the third to eighth weeks of pregnancy, when the major organ systems are forming.
