As per impulse momentum theorem we know that
now here we will have
t = 1.30 ms
m = 0.144 kg
now we need to find final speed using above formula
so final speed is given as above
The correct answer is
D. Groups and Families
I did the quiz nd this was the right answer
Hopes this helps :)
The correct answer should be <span>A. If you see a wear bar across the width of the tread, it's time to change the tire
This is an incorrect sentence because you should change a tire before you see the wear bar. At the time you see the bar, you should've already changed it. </span>
Explanation:
The speed of sound wave only depends on the property of the medium like density and the bulk modulus of the medium particle. The speed of sound also depends on the temperature of the medium.
On comparing sound waves with different frequencies and wavelengths traveling through air, the speed of the wave doesn’t depend on the frequency or the wavelength. Hence, the correct option is (1).
