Correct Answer: Nirbhay
Explanation:
Nirbhay missile is India's first indigenously designed and developed long range sub-sonic cruise missile.It is designed and made by DRDO (Defence Research & Development Organisation).The Nirbhay missile can be deployed from multiple platforms.
Correct Answer: Xenon
Explanation:
Electronic Flash differs from the consumable bulb flash in important aspects. Instead of creating light by burning up in an atmosphere containing oxygen, a consumable material (each bulb being used therefore only once), it produces a brilliant incandescent by discharging a current for a brief instant through a rarified gas, usually xenon. The gas glows every time the discharge is made through it but it is not consumed, so that many thousands of flashes are obtainable from a single tube, which helps to offset the much higher cost of the initial apparatus.
Correct Answer: Both the statements are individually true but Statement II is not the correct explanation of Statement I
Explanation:
Tides are the rise and fall of sea levels caused by the combined effects of the gravitational forces exerted by the Moon and the Sun and the rotation of Earth.
Statement 2 is also correct. But it is not the correct explanation for the 1st statement.
Correct Answer: Both the statements are individually true and Statement II is the correct explanation of Statement I
Explanation:
Glaciers cut distinctive U-shaped valleys with a flat floor and steep sides. These are an example of a glacial erosion landform.
Example: As the main glacier erodes deeper into the valley, the tributary is left higher up the steep sides of the glacier.
Correct Answer: Statement I is false but Statement II is true
Explanation:
Rejuvenation occurs when the river?s base level falls (i.e. when sea level falls). This can be a consequence of either a fall in the amount of sea water or the land rising. Incised meanders are meanders which are particularly well developed and occur when a river?s base level has fallen giving the river a large amount of vertical erosion power, allowing it to down cut. Hence, 2nd statement is correct.
There are two types of incised meanders, entrenched meanders and ingrown meanders.As they are products of rejuvenation, they are not formed in mature stage of a river
Correct Answer: Sugarcane
Correct Answer: All endangered species
Correct Answer: Nitrogen dioxide
