Answer:
option 4
Explanation:
Light's velocity in air ( 3 × 10^8 m/s ) is much greater than sound's velocity in air ( 343 m/s )
Hence due to difference in velocities , during lightning light is seen first & sound is heard later
Answer:
The displacement of the car is 10 km at an angle of 36.9 degrees.
Explanation:
(AP) A car travels 8.00 km west from A to B; then the car travels 6.0 km north from B to C. Calculate the total displacement of the car? to. 10 km 36.9 ° b. 10 km 34.8 ° c. 12 km 34.8 ° d. 12 km 34.8 ° e. 12 km 35.9 °
It is given that,
A car travels 8.00 km west from A to B
The car travels 6.0 km north from B to C
We need to find the total displacement of the car. Initially, the car is moving due west and then it moves due north. So, the displacement of the car is given by :
![d=\sqrt{8^2+6^2} =10\ km](https://tex.z-dn.net/?f=d%3D%5Csqrt%7B8%5E2%2B6%5E2%7D%20%3D10%5C%20km)
To find angle,
![\tan\theta=\dfrac{6}{8}\\\\\theta=\tan^{-1}(0.75)\\\\\theta=36.86^{\circ}\\\\\theta=36.9^{\circ}](https://tex.z-dn.net/?f=%5Ctan%5Ctheta%3D%5Cdfrac%7B6%7D%7B8%7D%5C%5C%5C%5C%5Ctheta%3D%5Ctan%5E%7B-1%7D%280.75%29%5C%5C%5C%5C%5Ctheta%3D36.86%5E%7B%5Ccirc%7D%5C%5C%5C%5C%5Ctheta%3D36.9%5E%7B%5Ccirc%7D)
So, the displacement of the car is 10 km at an angle of 36.9 degrees.
