Infared = used by police
gamma = short wavelength
radio = largest wavelength
visible = only ones we can see
Explanation:
We have,
The initial position of an object is zero.
The starting velocity is 3 m/s and the final velocity was 10 m/s.
The object moves with constant acceleration..
The area covered under the velocity-time graph gives displacement of the object. The correct option is "the area of the rectangle plus the area of the triangle under the line".
I am not completely sure, but I believe that it depends on the total mass of the Protons and Neutrons
Answer:
![u_{s}=0.56](https://tex.z-dn.net/?f=u_%7Bs%7D%3D0.56)
Explanation:
For the cat to stay in place on the merry go round without sliding the magnitude of maximum static friction must be equal to magnitude of centripetal force
![F_{s.max}=\frac{mv^2}{r} \\](https://tex.z-dn.net/?f=F_%7Bs.max%7D%3D%5Cfrac%7Bmv%5E2%7D%7Br%7D%20%5C%5C)
Where the r is the radius of merry-go-round and v is the tangential speed
but
![F_{s.max}=u_{s}F_{N}=u_{s}mg](https://tex.z-dn.net/?f=F_%7Bs.max%7D%3Du_%7Bs%7DF_%7BN%7D%3Du_%7Bs%7Dmg)
So we have
![u_{s}mg=\frac{mv^2}{r}\\ u_{s}=\frac{v^2}{gr}\\ Where\\v=\frac{2\pi R}{T} \\So\\u_{s}=\frac{(\frac{2\pi R}{T} )^2}{gr} \\u_{s}=\frac{4\pi^2 r}{gT^2}](https://tex.z-dn.net/?f=u_%7Bs%7Dmg%3D%5Cfrac%7Bmv%5E2%7D%7Br%7D%5C%5C%20u_%7Bs%7D%3D%5Cfrac%7Bv%5E2%7D%7Bgr%7D%5C%5C%20Where%5C%5Cv%3D%5Cfrac%7B2%5Cpi%20R%7D%7BT%7D%20%5C%5CSo%5C%5Cu_%7Bs%7D%3D%5Cfrac%7B%28%5Cfrac%7B2%5Cpi%20R%7D%7BT%7D%20%29%5E2%7D%7Bgr%7D%20%5C%5Cu_%7Bs%7D%3D%5Cfrac%7B4%5Cpi%5E2%20r%7D%7BgT%5E2%7D)
Substitute the given values
So
![u_{s}=\frac{4\pi^2 5.5m}{(9.8m/s^2)(6.3s)^2} \\u_{s}=0.56](https://tex.z-dn.net/?f=u_%7Bs%7D%3D%5Cfrac%7B4%5Cpi%5E2%205.5m%7D%7B%289.8m%2Fs%5E2%29%286.3s%29%5E2%7D%20%5C%5Cu_%7Bs%7D%3D0.56)
Answer:
Yes, the relationships you observe in childhood affects the quality of your current relationships.
Explanation:
The saying,<em> "Children see, children do,"</em> is evidently true. A child's lifestyle and future relationships are greatly affected by the kind of relationships you allow him to see. Thus, it is very important that parents become role models for their kids.
For example, when your parents handle stress by shouting at each other, then most likely you'd also handle stress the same way in the future. So,<em> it is essential that the role models will show the child how to handle stress positively.</em> The experiences that children have at a young age affects their adult life.<u> It influences them and shapes them into who they will become.</u>
If people at home show positive relationships with each other and also supports a child regarding his education, then the child will most likely set positive relationships with his peers and achieve higher degree standards.
Thus, this explains the answer.
