when the stop time is 10 seconds,it gives a proper sine curve, but when I increase the time it gives the sine graph unlike sine graph.Pls help me with this, why is this happening?

I reckon that you are using variable time step so when you increase your time, time step also increases. So, the curve is not as smooth as you have expected. To solve this use fixed time step and keep it small to get smoother curve.
Go to File->Simulink Preferences->Under Sover option, choose "fixed step" type and then choose fixed time step like 1ms
