A speeding Thunderbird left skid marks on the road that were 76.7 m long when it came to a stop. If the acceleration of the car

FrozenT [24]

Answer: 39.2 m/s

Explanation:

You can use the kinematic equation:

$v_f^2=v_i^2+2a*d$

We know the final velocity because it says it came to a stop. So now all we gotta do is plug in.

$0^2=v_i^2+2(-10)(76.7)\\v_i^2=1,534\\v_i=\sqrt{1534} \\=39.166 m/s$

What is the wavelength of the carrier wave of a campus radio station, broadcasting at a frequency of 97.2 MHz (million cycles pe

andrey2020 [161]

Answer:

Wavelength is 3.08 meters.

Explanation:

It is given that,

Frequency, $f=97.2\ MHz=97.2\times 10^6\ Hz$

We need to find the wavelength of the carrier wave of a campus radio station. It can be calculated by using following relation as :

$c=f\times \lambda$

$\lambda=\dfrac{c}{f}$

$\lambda=\dfrac{3\times 10^8\ m/s}{97.2\times 10^6\ Hz}$

$\lambda=3.08\ m$

So, the wavelength of the carrier wave is 3.08 meters. Hence, this is the required solution.
