Answer:
Microwave spectroscopy is the spectroscopy method that employs microwaves, i.e. electromagnetic radiation at GHz frequencies, for the study of matter
Answer:
The average speed of the runner is 18.2 km/h.
Explanation:
Hi there!
The average speed is calculated as the traveled distance over time:
speed = traveled distance / elapsed time to cover that distance
We have to find the speed in km/h, so let´s start converting the time into hours:
23 s · (1 min/60 s) = 0.38 min
15.38 min · (1 h / 60 min) = 0.26 h
Total time: 0.26 h + 2 h = 2.26 h
The distance traveled in km is:
25.5 mi · (1.61 km/ 1 mi) = 41.1 km
Then, the average speed will be:
speed = 41.1 km / 2.26 h = 18.2 km/h
The average speed of the runner is 18.2 km/h.

In BPC
tan\theta =a/b = 3/4
\theta = tan^-1(0.75)
\theta = 36.87 deg
BP = sqrt(a^2 + b^2) = sqrt((3)^2 + (4)^2) = 5 m
Eb = k Q/BP^2 = (9 x 10^9) (16 x 10^-9)/5^2 = 5.76 N/C
Ea = k Q/AP^2 = (9 x 10^9) (16 x 10^-9)/4^2 = 9 N/C
Ec = k Q/CP^2 = (9 x 10^9) (16 x 10^-9)/3^2 = 16 N/C
Net electric field along X-direction is given as
Ex = Ea + Eb Cos36.87 = (9) + (5.76) Cos36.87 = 13.6 N/C
Net electric field along X-direction is given as
Ey = Ec + Eb Sin36.87 = (16) + (5.76) Sin36.87 = 19.5 N/C
Net electric field is given as
E = sqrt(Ex^2 + Ey^2) = sqrt((13.6)^2 + (19.5)^2) = 23.8 N/C
A is the best answer. This is what makes the magnetic field of the magnet.
