The formula to determine the height of the rocket above the ground at any time during the rocket's flight is given by: h = 119t - 7t2 where t = the time, in seconds, that has elapsed since the rocket was launched, and h = the height, in meters, of the rocket above the ground at time t. The value of h was 0 when the rocket hit the ground. How many seconds after the rocket was launched did it hit the ground?
A map shows the elevations of Darjeeling, Gangtok, Kalimpong, Pelling, and Siliguri. Kalimpong is at a lower elevation than Gangtok, Pelling is at a lower elevation than Gangtok. Pelling is at a higher elevation than Siliguri. Darjeeling is at a higher elevation than Gangtok. Which of the following statements can be inferred from the paragraph above? i. Pelling is at a higher elevation than Kalimpong ii. Kalimpong is at a lower elevation than Darjeeling iii. Kalimpong is at a higher elevation than Siliguri iv. Siliguri is at a lower elevation than Gangtok
Consider two rocket engines A and B with A having a specific impulse of 242s and B having a specific impulse of 150s. What can be said about their efficiency?
The upper part of the rocket is in the shape of a right circular cone of height 3m while its lower part is cylindrical having a radius of 3m and height of 10m. The base of the rocket is cut in a semicircular form from the inside to make room for the engine. Whose radius is also 3m. Find the total volume of the rocket in cubic metres.
In the question, the first and last sentences of the passage are numbered 1 and 6. The rest of the passage is split into four parts and named P, Q, R, and S. These four parts are not given in their proper order. Read the sentence and find out which of the four combinations is correct. S1: When a satellite is launched, the rocket begins by going slowly upwards through the air. P: However, the higher it goes, the less air it meets. Q: As the rocket goes higher, it travels faster. R: For the atmosphere becomes thinner. S: As a result, there is less friction. S6: Consequently, the rocket still does not become too hot. The Proper sequence should be:
In the following question, sentences of a paragraph have been jumbled and labelled as A, B, C and D. You are required to rearrange the jumbled sentences of the paragraph and mark your response accordingly by selecting the correct option. A: However, the higher it goes, the less air it meets. B: When a satellite is launched, the rocket begins by going slowly upwards through the air, as the rocket goes higher, it travels faster. C: For the atmosphere becomes thinner resulting in less fristing. D: Consequently, the rocket still does not become too hot.
