The SI unit for measuring an electric current is the ampere, which is the flow of electric charge across a surface at the rate of one coulomb per second. Electric current is measured using a device called an ammeter.
An IPv4 address is divided into two parts: network and host address. The network address determines how many of the 32 bits are used for the network address and the remaining bits are used for the host address.
Q3. Process of loosing electrons is known as _____.
इलेक्ट्रोन प्रदान करने की क्रिया को ________कहते हैं |
(a) oxidation/ ऑक्सीकरण
(b) reduction/ अपचयन
(c) radiation/ विकिरण
(d) both oxidation and reduction/ ऑक्सीकरण तथा अपचयन दोनों
Bubbles are round — spherical — because there is an attractive force called surface tension that pulls molecules of water into the tightest possible groupings. … In a bubble, the inward surface-tension forces of the water film are exactly balanced by the outward-pushing pressure of the air inside.
Q5. CAD stands for _____.
सी.ए.डी. का असंक्षिप्त नाम________है |
(a) Common Aided Design/ कॉमन एडेड डिजाईन
(b) Computer Aided Design/ कंप्यूटर एडेड डिजाईन
(c) Complex Aided Design/ काम्प्लेक्स एडेड डिजाईन
(d) Communication Aided Design/ कम्युनिकेशन एडेड डिजाईन
Exothermic reactions may occur spontaneously and result in higher randomness or entropy of the system. They are denoted by a negative heat flow (heat is lost to the surroundings) and decrease in enthalpy.
Q7. Which colour is formed when Red and Green are mixed? लाल तथा हर
लाल तथा हरे रंग के मिश्रण से कौन सा रंग प्राप्त होता है?
JPEG is a commonly used method of lossy compression for digital images, particularly for those images produced by digital photography. The degree of compression can be adjusted, allowing a selectable tradeoff between storage size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.
Q9. What is an endothermic reaction?
एक ऊष्माशोषी प्रतिक्रिया क्या होती है?
(a) Reaction in which heat is released./ प्रतिक्रिया जिसमें ऊष्मा विमोचित होती है |
(b) Reaction in which heat is absorbed./ प्रतिक्रिया जिसमें ऊष्मा अवशोषित होती है |
(c) Reaction in which neither heat is released nor absorbed./ प्रतिक्रिया जिसमें न तो ऊष्मा विमोचित होती है और न ही अवशोषित होती है|
The Kelvin scale is an absolute thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics. The kelvin (symbol: K) is the base unit of temperature in the International System of Units (SI).
Q11. Netscape Navigator is a________.
नेटस्केप नेविगेटर एक_____है |
(a) graphical user interface/ ग्राफिकल यूज़र इंटरफ़ेस या चित्रितोप योजक सम्पर्क साधन
(b) programming language/ प्रोग्रामिंग भाषा या क्रमादेशन भाषा
(c) web browser/ वेब ब्राउज़र या वेब पृष्ठ परिवर्तक
Netscape Navigator is a discontinued proprietary web browser, and the original browser of the Netscape line, from versions 1 to 4.08, and 9.x. It was the flagship product of the Netscape Communications Corp and was the dominant web browser in terms of usage share in the 1990s, but by 2002 its usage had almost disappeared
Actually, milk has a pH of around 6.5 to 6.7, which makes it slightly acidic. Some sources cite milk as being neutral since it is so close to the neutral pH of 7.0. Milk contains lactic acid, which is a hydrogen donor or proton donor.
