Kids fall in love so quick because they have no idea what it is. Many of them get "broken hearted" But in actuality they have no idea what that is either. Love is an intense feeling of deep affection. Youths don't understand the freedom they have without someone. They only focus on what life would be with someone. Even though they don't understand everything. What I am trying to get at is, adults have more experience in the open world and how people grow up to be. Kids are just in school with the same people everyday thinking "hey I'm gonna be stuck with these people for the next 4 years might as well become more than friends"
Get what I mean? Hope this helps!
With the presence of science during the scientific revolution, people were no longer very permissive to ideas about nature that were solely based on someone's perception. It should be scientifically studied and have undergone scientific method for it to be generally accepted as true.
Answer:
12 cm
Explanation:
Mirrors work on the principle of reflection.
Reflection occurs when a ray of light bounces off a surface, being reflecting back into the original medium.
Mirrors are surfaces over which light is reflected; as a result, objects placed in front of a mirror produce an image of themselves.
There are two types of mirrors:
- Curved mirrors: this mirrors are curved, and are further divided into convex mirrors and concave mirrors. These mirrors can produce images that are real or virtual, bigger or smaller tha the original objects, and also upright or inverted, depending on the position of the object with respect to the mirror
- Flat mirrors: these mirrors are perfectly flat. The image produced by a flat mirror is:
- The same size as the object
- Laterally inverted
- Upright
- At the same distance as the object from the mirror (4)
- Virtual (it appears "behind" the mirror)
In this problem, the object is located 12 cm in front of the mirror. According to statement (4), the image produced by a flat mirror is at the same distance as the object: therefore in this case, it is 12 cm.
Answer:
The velocity of ball and man after catching ball is ![2m/s](https://tex.z-dn.net/?f=2m%2Fs)
Explanation:
Since there is no friction and no external force the momentum is conserved .
Here when man catches ball then man and ball move with common velocity .
Let the final common velocity be
,
Given that mass of the ball is
=![15kg](https://tex.z-dn.net/?f=15kg)
Given that mass of man is ![m=60kg](https://tex.z-dn.net/?f=m%3D60kg)
Initial velocity of ball = ![v_{i} = 10m/s](https://tex.z-dn.net/?f=v_%7Bi%7D%20%3D%2010m%2Fs)
Now considering momentum conservation
![p_{i} =p_{f}](https://tex.z-dn.net/?f=p_%7Bi%7D%20%3Dp_%7Bf%7D)
![m_{b}v_{i} = (m_{b} +m)\times v\\v=m_{b}v_{i}/(m_{b} +m) = \frac{150}{75} =2m/s](https://tex.z-dn.net/?f=m_%7Bb%7Dv_%7Bi%7D%20%3D%20%28m_%7Bb%7D%20%2Bm%29%5Ctimes%20v%5C%5Cv%3Dm_%7Bb%7Dv_%7Bi%7D%2F%28m_%7Bb%7D%20%2Bm%29%20%3D%20%5Cfrac%7B150%7D%7B75%7D%20%3D2m%2Fs)
The strength of the gravitational forces between two masses depends on
-- the product of the masses,
-- the distance between their centers of mass.
