Answer:
Speed in meter/sec will be 32.1777 m /sec
Explanation:
We have given speed = 72.4 miles per hour
We have to convert this speed in meter per second
We know that 1 miles = 1.6 km
So 72.4 miles = 72.4×1.6= 115.84 km
We also know that 1 km = 1000 m
So 115.84 km 
We know that 1 hour = 60×60 = 3600 sec
So 
A and C
Imagine u are shooting a laser pointer at a mirror this is pretty much what it is
Answer:
1.047 rad
Explanation:
A secondhand makes a complete revolution (360 degrees) in 60 seconds, so it displaces 6 degrees for every second of elapsed time (360/60 = 6).
And in 10 seconds, it will make a displacement of 10 degrees (6 * 10 = 60).
Finally converting the result into Radians by multiplication with π/180.
Well are having freckles recessive or dominant?
Answer
From the question we can see that the in medium 1 speed of light is 200,000 Km/s where as in Medium 2 speed of light is 250,000 km/s.
We can conclude that medium 1 is denser than Medium 2.
In third medium Light speed halts so, the third medium is opaque.
We can say that
Medium 1 can be either water, glass.
Medium 2 will be gas
Medium 3 will be an opaque material.
