The relationship of the speed of sound, its frequency, and wavelength is the same as for all waves: vw = fλ, where vw is the speed of sound, f is its frequency, and λ is its wavelength. ... The frequency is the same as that of the source and is the number of waves that pass a point per unit time.
Put a parashoot on it so it touches the ground lightly and carefully
According to the statement there is a force of repulsion between the two objects. Remember that two objects must have the same charge so that they repel each other. In this way if the tape is repelled by a plastic pen that is negatively charged, this allows us to appreciate that the tape is also negatively charged. Now if the tape repels the sphere, therefore the sphere is also negatively charged.
Under these considerations the correct answers would be
2. Sodium ions from the salt water on your hand moved onto the sphere
4. The excess negative charge from the sphere spread out all over your body
6. Electrons from the sphere moved into the salt water on your skin, where they reacted with sodium ions
7. After you touched it, the metal sphere was very nearly neutral.
Answer:
A. The iron-nickel alloy melts due to hot temperatures.
Explanation:
<span>y=x-50
where y is the reading test score and and x is iq score.
This can be found intuitively. Since each point in IQ should increase the score by one point, we know the slope should be 1. Then we use the fact that reading test score is just iq shifted down by 50. This leads to the subtraction of 50.</span>
