The answer would be C. increasing the sound of charge on each particle by a factor of 9
Answer:
Frequency is expressed in Hertz, which is simply cycles per second. If a tuning fork (or anything else, for that matter) vibrates 1 time each second, it's frequency is 1 Hz. So then, if it vibrates 4280 in 20 seconds, then 4280÷20=214 cycles per second = 214 Hz.
<span>Answer:
6- for an object to accelerate, Newton's law #2 tells us there must be a force acting on it. F=ma the effect of a force is to accelerate the mass .
It cannot be 1, because the force must be centripetal to move the object in a circle. it can't be 2 because if an object is accelerating the velocity cannot be constant as it is moving faster. It can't be 3 because a stationary object has a net force of 0. 4 has nothing to do with the question. 5- no force is needed for uniform motion. 7- that is impossible.</span>
The equation that shows the relationship between X₁ and X₂ in the springs is X₁ = 4X₂.
<h3>How to compute the equation?</h3>
From the complete question, for case I, the two springs stretch up to the distance of X₁. Therefore, f = mg = kx₁.
For case 2, f = mg = kx₂.
Therefore, we'll equate the equations. This will be:
Kx₁ = Kx₂
(K/2)x₁ = (2k)x₂
K(x₁/2) = k(2x₂)
X₁/2 = 2x₂
X1 = 2 × 2x₂
X₁ = 4X₂.
In conclusion, X₁ = 4X₂.
