<h3><u>Answer;</u></h3>
D) Standing wave
<h3><u>Explanation;</u></h3>
- Standing wave also called stationary wave is a wave which oscillates in time but whose peak amplitude profile does not move in space.
- A standing wave pattern is a vibrational pattern created within a medium when the vibrational frequency of the source causes reflected waves from one end of the medium to interfere with incident waves from the source.
- Examples of standing waves include the vibration of a violin string and electron orbitals in an atom.
Answer:0.6
Explanation:
Given
Bowl contains 4 red and 2 Green balls
Probability of selecting two red balls given atleast one of the ball is red + Probability of selecting two red balls given that no ball is red =1
Probability of selecting two red balls given that no ball is red ![=\frac{Probability \ of\ selecting\ two\ red\ balls\ out\ of\ 4\ balls}{probability\ of\ selecting\ 2\ balls\ out\ of\ 6 balls}](https://tex.z-dn.net/?f=%3D%5Cfrac%7BProbability%20%5C%20of%5C%20selecting%5C%20two%5C%20red%5C%20balls%5C%20out%5C%20of%5C%204%5C%20balls%7D%7Bprobability%5C%20of%5C%20selecting%5C%202%5C%20balls%5C%20out%5C%20of%5C%206%20balls%7D)

Answer:
a 200 feet, and trains go a whole mile even after hitting the brakes
Explanation:
Each
ion contains three extra protons. Hence, the extra charge on each
=
C
Total charge = 0.035 pC
Total charge (Q) =
C
Let the number of
ions be n.
According to question:
![n \times 3 \times 1.6 \times 10^-^1^9 =0.035 \times 10^-^1^2](https://tex.z-dn.net/?f=n%20%5Ctimes%203%20%5Ctimes%201.6%20%5Ctimes%2010%5E-%5E1%5E9%20%3D0.035%20%5Ctimes%2010%5E-%5E1%5E2)
![n = \frac{0.035 \times 10^-^1^2}{3 \times 1.6 \times 10^-^1^9}](https://tex.z-dn.net/?f=n%20%3D%20%5Cfrac%7B0.035%20%5Ctimes%2010%5E-%5E1%5E2%7D%7B3%20%5Ctimes%201.6%20%5Ctimes%2010%5E-%5E1%5E9%7D)
![n = 7.29167 \times 10^4](https://tex.z-dn.net/?f=n%20%3D%207.29167%20%5Ctimes%2010%5E4)
n = 72917
Hence, the total number of ions needed to be transferred is 72917
Answer:
B. Any object that has motion has potential energy, wow any object not in motion light with the potential to do work and kinetic.
Explanation:
Potential Energy is the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors. Kinetic Energy is energy which a body possesses by virtue of being in motion.
