Answer:
Reflection
Explanation:
Reflection is the property of light in which when a ray of light hits a smooth surface, it bounces back in the direction in which it came from. If i is the angle between the normal to the surface and the incident ray, and r is the angle between the normal and reflected ray, the law of reflection states that the angle of incidence equals the angle of reflection. That is, i = r.
So, to record the image of an object with a camera, one property of light that makes that possible is reflection because, the incidence rays form an image of the object in the camera, while the reflected rays reflect the image so that it is visible to the eye.
Assuming that each period indicates a new answer choice,
Answer:
Electronic notebook.
That would be the best choice because that's pretty much what it is, an electronic notebook.
Hope this helps!
Having a bachelor degree from a college gives the highest returns on investments. People who go to college usually secure high paying jobs compare to their counterparts who have less education.
The type of college one attends also matter, for instance in USA, the college in the first position, which gives the highest return on investment is Massachusetts Institute of Technology [MIT].
Answer:
#include <stdio.h> #define Gray 32.17 /* gravitational constant */ #include <math.h> /*cos definition*/ #define PI 3.14159265
int main(void) double Theta; /*input-angle(radians)of elevation*/ double Distance; /*input-distance (ft) to target */ double Velocity; /*input-projectile velocity (ft/sec)*/ double Time; /* output-time(sec) of flight*/ double Height; /*output-height at impact*/
printf("Enter Distance> "); scanf("%f", &Distance);
printf("Enter Radians> "); scanf("%f", &Theta);
printf("Enter Velocity> "); scanf("%f", &Velocity
Time = Distance / (Velocity * cos(Theta*PI/180.0) ) ;
Height = (Velocity *sin(Theta*PI/180.0)*Time) - Grav*(Time* Time) );
printf("The time of flight is %.3f seconds.\n", Time); printf("The height at impact is %.3f feets.\n", Height);
system("pause");
return (0);
