Answer:
Explanation:
In a standing wave function characterized for x between (0.a). on the off chance that the amplitude of the wave interchange from positive to negative at the interval. there probably been a node at , among 0 and a to such an extent that . The reasoning is right that the likelihood of discovering the particle at the node is 0 in light of the fact that by definition, the nodes of the wave are the place where the wave function falls and is equivalent to 0. Since the likelihood of discovering a particle at a position at time , is provided by , this implies that at the nodes of a standing wave,
So the reasoning that the likelihood of the particle being at is 0 is right.
However, to examine whether the particle can travel from a position to a position of . All together words, can the molecule be found on one or the other side of the node?
The appropriate response is yes.
Recall that in quantum mechanics. wave functions at most present with the likelihood of discovering a particle at a specific time inside a time frame. The wave function doesn't present with an old classical actual trajectory that a particle should follow to go in space: all things being equal, it simply yields chances of whether a particle can be found in a specific spot at a specific time. So the reasoning that a particle can't get from a position to a position of , is incorrect.
Answer: 1.044 E -17 A
Explanation:
L =1.50m
A = 0.380mm = 3.8E- 7
Resistivity p =1.70 E-8
R =pl/A
R = 1.70 E-8 × 1.5/ 3.8 E-7
R = 6.71 E-16 ohms
V = IR
0.700 = I × 6.71 E-16
I =1.044E-17 A
Answer:
A. It must stay the same, but kinetic energy (KE) can be transformed to PE and PE can be transformed to KE within the system.
Explanation:
Energy can be defined as the ability (capacity) to do work. The two (2) main types of energy are;
a. Potential energy (PE): it is an energy possessed by an object or body due to its position above the earth.
b. Kinetic energy (KE): it is an energy possessed by an object or body due to its motion.
Furthermore, the total energy of a physical object or body is the sum of the potential energy and kinetic energy possessed by the object or body.
Mathematically, it is given by the formula;
Total energy = P.E + K.E
The Law of Conservation of Energy states that energy cannot be destroyed but can only be transformed or converted from one form to another.
In this scenario, a system has both potential energy (PE) and kinetic energy (KE).
According to the law of conservation of energy, we can infer or deduce that the total energy of the system must stay the same because it cannot be destroyed, but kinetic energy (KE) can be transformed to potential energy (PE) and potential energy (PE) can be transformed to kinetic energy (KE) within the system.
To find density of an irregular object, you need to find the mass and volume.
The tool you need is a triple beam balance, a graduated cylinder, and paper, pencil, etc
