Green theorem proof |
|
Answer» ANSWER:Green's theorem is used to INTEGRATE the derivatives in a PARTICULAR plane. If a line integral is given, it is converted into surface integral or the double integral or vice versa using this theorem....Therefore, we can write the area formulas as: A = -\int_{c}ydx. A = \int_{c}xdy. A = \frac{1}{2}\int_{c}(xdy-ydx) |

The image of the sun formed by a concave mirror is always a dot. Give reason. |
|
Answer» Explanation: The image of the sun formed by the concave mirror is always dot because , the light rays of the sun falling from the Infinity distance will be meeting at the focal point according to the laws of reflection of SPHERICAL Mirrors and as concave mirror is a focusing mirror all the rays coming from the Infinity of the sunlight will GET focus at ONE point and thus the image of the Sun by the concave mirror is always the dot and that image also burns the paper because of the sun's heat l plz MARK me as brainliest hope u like the answer |

Define uniform circular motion why is it said to be an accelerated |
Answer» Answer :-The motion of a body along the circumference of the circle is called circular motion. Uniform circular motion :- If a body covers equal distances in equal interval of time, then motion is said to be uniform circular motion. In a uniform circular motion, speed remains constant but DIRECTION of velocity changes. Uniform circular motion is called ACCELERATED because in the circular motion direction of motion continuously changes. Due to CHANGE in direction, velocity also changes CONSTANTLY. As we KNOW that, acceleration is the rate of change of velocity, and in the circular motion velocity continuously changes, circular motion is called accelerated motion. |

A calorimeter has mass 100 g andspecific heat 0.1 kcal/ kg °C. Itcontains 250 gm of liquid at 30 °Chaving specific heat of 0.4 kcal/kg°C. If we drop a piece of ice of mass10 g at 0 °C, What will be thetemperature of the mixture? |
|
Answer» Answer: 20.83°C Explanation: Solution Let the final temperature attained be T. then, heat given by CALORIMETER + heat given by liquid = heat absorbed by ice ⇒Mc SC(30−T)+MLSL (30−T) =MI[Lfusion+SW(T−0)] ⇒(100)(0.1)(30−T)+(250)(0.4)(30−T) =10[80+1(T−0)] ⇒(110)(30−T)=10[80+T] ⇒330−11T=80+T ⇒T= 12(330−80) =20.83° C |
