2. A new racecar track is being created, and the owners want the cars to complete 10
jeka57 [31]

Answer:

0.45 miles

Explanation:

since, car will be running on the edge of track, distance covered in one lap by car will be equal to circumference of track.\

we will use value of pi as 22/7

Circumference for any circular shape is given by \piD\pi D

Hence, in one lap \pi D distance will be covered

in 7 laps 7 \pi D distance will be covered.

but is given that 7 laps should be equal to 10 miles

so 10 miles will be equal to 7\pi D

7\pi D= 10 \ miles\\=> 7*(22/7)* D= 10 \ miles\\=> 22D = 10 \ miles\\=> D = 10/22 \ miles\\=> D = 0.45 \ miles

Thus, diameter of track will be 0.45 miles to meet the requirement.

Two waves are superposed. one wave has an amplitude of 5 cm, and other has an amplitude of 4 cm. What is the resultant amplitude
Vsevolod [243]
If both waves have the same wavelength, then the amplitude of
their sum could be anything between 1 cm and 9 cm, depending
on the phase angle between them.

If the waves have different wavelengths, then the resultant is a beat
with an amplitude of 9 cm.
