Answer:
Net force = 20 N
Explanation:
Given that,
Force acting on the left = 10 N
Force acting on the right = 30 N
Let right side is positive and left side is negative. Let the net force acting on the box is F. So,
F = -10+30
F = 20 N
So, the net force on the box is 20 N and it is in right side.
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.

Explanation:
Almost all smartphone devices have global positioning satellite (GPS) service capabilities in them, which mean that apps will be able to combine the phone user's location with the available retail outlets and services to build better mobile business opportunities. For instance, some applications can navigate the user to a particular business locations (such as movie theaters, restaurants, or a nearby auto repair facilities) based on the user's present location.
App like twitter can use the GPS capability to tailor yhier user feeds and timelines with digital contents that are intresting to users in that location.
amazon can advertise based on the need of consumers in a particular location.
Google also tailor thier adword and adsense advert based on the location of the user.
