<span>The distance between the beginning of the first P wave and the first S wave tells you how many seconds the waves are apart. This number will be used to tell you how far your seismograph is from the epicenter of the earthquake. Measure the distance between the first P wave and the first S wave.</span>
Answer:
D. Toy pulls on the child in the opposite direction
Explanation:
Newton third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever an object 1 exerts a force (action force) on another object 2, object 2 exerts a force (reaction force) of equal magnitude but opposite direction on object 1.
According to this question, a child pulls a toy across the floor. Based on Newton third law described above, the toy will pull the child with an opposite force that is equal in magnitude. Hence, the equal and opposite force is: Toy pulls on the child in the opposite direction.
Answer:
Atoms have the same number of electrons and protons and hence have net 0 charge. When an atom gains or loses an electron, it attains a net charge and becomes an ion. When electrons are lost (or donated), the resulting ion is called cation. When electrons are gained, the resulting ion is called an anion.
