Question :-
- What is the Speed of a Wave that has a Frequency of 250 Hertz and a Wavelength of 1.5 meter ?
Answer :-
- Speed of the Wave is 350 m/s .
Explanation :-
As per the provided information in the given question, we have been given that the Frequency of the Sound Wave is 250 Hertz. Its Wavelenght is given as 1.5 Meter. And, we have been asked to calculate the Speed of the Wave.
For calculating the Speed , we will use the Formula :-
Therefore , by Substituting the given values in the above Formula :-
Hence :-
- Speed of the Wave = 375 m/s .
ANSWER: 2 hours
EXPLANATION: After three hours Austin has traveled 12 miles. Wyatt will start up and in an hour will be at 10 miles, but by that time Austin will be at 16 miles. One more mile and Wyatt will be at 20 miles and so will Austin. So that would make the answer 2 hours.
Around 750 to 1,500.

Chemical properties are based on the ability or inability of the substance to produce new substances. Copper's malleability, color, luster, and thermal and electrical conductivity are contrasted with its ability to react with concentrated nitric acid and silver nitrate. Copper has a melting point of 1083.4 +/- 0.2°C, boiling point of 2567°C, specific gravity of 8.96 (20°C)
so its D

You can approach this problem in an analytical way. The formula for kinetic energy is 1/2*mv². Throughout the projectile motion, mass is constant. Therefore, it wholly depends on the velocity.<em> So, the maximum kinetic energy is when the object travels the fastest. This is right when it leaves the launcher, and the moment just before it hits the ground.</em>
