What is a feature of an optimal rocket?

What is a feature of an optimal rocket? Correct Answer Highest payload ratio efficiency

Optimal rockets are those rockets which can carry maximum payload with least non-payload mass upto the burnout velocity. The payload mass is maximum for a particular total velocity impulse applied.

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?

We usually use feature normalization before using the Gaussian kernel in SVM. What is true about feature normalization?
1. We do feature normalization so that new feature will dominate other
2. Some times, feature normalization is not feasible in case of categorical variables
3. Feature normalization always helps when we use Gaussian kernel in SVM
In a engineering, test, a rocket sled is propelled into a target. If the sled's distance d in meters from the target is given by the fomula d = - 1.5 t2+120, where t is the number of seconds after rocket ignition, then how many seconds have passed since rocket ignition when the sled is 10 meters from the target?
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:
