The correct answer for the question that is being presented above is this one: "B. 13m." 

The formula of wave velocity is this:
wave velocity = f * <span>λ
</span>λ = v / f
<span>λ</span> = 343m/s / 26Hz
λ = 13.20m .. ans (b) 

Here are the following choices:
A. 5m 
B. 13m 
C. 28m 
D. 58m

Determine the potential difference between two charged parallel plates that are 0.50 cm apart and have an electric field strengt
jeka57 [31]
If the field strength between the plates is 9 volts per cm, then over a path of 1/2cm parallel to the field, the potential changes by (1/2) x (9 volts) = 4.5 volts.

Examine the scenario. Two neutral objects, a balloon and a sweater, are rubbed against each other. Which choice most accurately
Ne4ueva [31]

Electrons move from the sweater to the balloon. The sweater becomes positively charged, while the balloon becomes negatively charged.

Explanation:

  • Sweater is a conductive material, which means it readily gives away its electrons.
  • Consequently, when you rub a balloon on Sweater, this causes the electrons to move from the Sweater to the balloon's surface.
  • The rubbed part of the balloon now acquired  a negative charge. Objects made of rubber, such as the balloon, are basically electrical insulators, meaning that they resist electric charges flowing through them.
  • This is why only part of the balloon may have a negative charge (where the wool rubbed it) and the rest may remain neutral after electrostatic process.

Need help in knowing what energy it’s using
ser-zykov [4K]

Answer:

8:P.E,9:gaining K.E,10:P.E,11:gaining K.E.

Explanation:

it gained potential energy at 8 because it was at its maximum height,and since potential energy is the energy that u posses due to ur height,thats the energy it possesed on the spot 8.as you can see on spot 9 its moving down so as its moving down,it gains kinetic energy,since its an energy possesed by a body due to its motion/movement,thats what it gained at spot 9, it gsained kineti energy because of its movement.and at 10 agian it would gain potential energy ecause of height and on point 11 as its heading upwards it gains kinetic energy because of movement.

What happens when light is allowed to pass through a suspension
Nutka1998 [239]

Answer:

When light is passed through a true solution, the dissolved are too small to deflect light. suspensions may scatter light, but if the number of suspended particles is sufficiently large, the suspension may simply be opaque, and the light scattering would not occur.
