I'm so sorry I took long, I'm answering answer after answer :)
Not sure if this is helpful :)
I know these are things in order for an animal to be endangered, but just pick answer that's not these I guess? "Which of the following"
Answer:
263.1 is exactly three half-life, so the remaining portion is (1/2 x 1/2 x 1/2) of the original sample. That's 1/8 which is 12.5%
Answer:
ya thats right
Explanation:
here is one explanation i found on the web:
Answer: The true statements are "the operation of a motor depends on the relationship between electric and magnetic forces" and "Electric forces and magnetic forces are different aspects of a single electromagnetic force.".
Explanation:
The electric force is due to the forces acting between the charges. The magnetic force is the force exerted between the magnets or moving charged particles.
The electromagnetic force is created by the magnetic field and the electric field.
The magnetic force is related to the electric force. These forces are different aspects of single electromagnetic force. The moving charge produce the magnetic force. The moving magnet produce the electric forces. The interplay of electric field and the magnetic force is the basis for motor.
Motor converts the electrical energy into mechanical energy. The operation of a motor depends on the relationship between electric and magnetic forces.
Therefore, the true statements are "the operation of a motor depends on the relationship between electric and magnetic forces" and "Electric forces and magnetic forces are different aspects of a single electromagnetic force.".
Answer:
The electron stays in an excited state for a short time. When the electron transits from an excited state to its lower energy state, it will gice off the same amound of energy needed to raise to that level. This emitted energy is a photon.
Here, substitution reaction is undergoing and the energy levels of each reaction phase is marked in graph. Its an exothermic reaction.
<h3><u>Explanation:</u></h3>
The substitution reaction is a type of reaction where a part of a molecule is substituted by another molecule to produce 2 products.
Here in the graph, in phase A we can see two molecules are coming in a reaction and they are at a particular energy level as marked. In phase B, we can see that the molecules are undergoing the substitution reaction via SN² reaction where the energy level is higher than the original energy level because of the activation energy. The difference between the energy levels is called the activation energy which is marked as D.
The final phase is the final energy levels of these 2 products where the energy level is much lower than original energy level. So the energy is lost through the reaction as heat. So the reaction is exothermic.
