How could you be a leader in your family an/or community

Answers

you could be a leader in the family by doing what’s right. if you see your siblings not doing anything to help out your parents then be the better person and help them out, it’s tough being a parent who works and has kids to take care of. helping them will mean a lot and you’re siblings could see that and help out too

Why couldn't the Mars Science Laboratory land using airbags to bounce to the Martian surface from a parachute?

A. The presence of liquid water made it necessary to land the rover on its wheels.

B. Scientists and engineers were concerned that the airbags could become tangled in the MSL.

C. Engineers were worried the airbags might deflate too soon.

D. The heavier weight of the MSL made airbag landing technology impractical.

Answers

Answer: D. The heavier weight of the MSL made airbag landing technology impractical.

Explanation:

Airbags have been used by NASA before to land objects on Mars such as during the Pathfinder and Spirit and Opportunity missions due to their practicality in landing in a planet like Mars with its thin atmosphere.

This however could not be used for the Mars Science Laboratory mission because the rover involved which was called Curiosity, was simply too heavy to use airbags to land.

Answer:

The heavier weight of the MSL made airbag landing technology impractical.

Experiment 1: A study is done to determine which of two fuel mixtures allows a rocket to travel farther over a period of time. Rocket A, which requires additional equipment to keep it stable, is used to test one fuel mixture, and rocket B is used to test the other. Both rockets are identical aside from their mass. The results indicate that rocket B traveled farther than rocket A over the same period of time. Experiment 2: A double-blind experiment is performed to test whether a new drug is effective in lowering blood pressure. A random sample of subjects with high blood pressure is assigned to two groups. One group receives the new drug and the other group does not. Neither group is permitted to take any other medications during the experiment or to change their lifestyles in any way. The results of the experiment show that the drug is effective in lowering blood pressure. Identify the experiment in which confounding occurs and the reason for its occurrence.a. Neither experiment has a confounding variable.b. Experiment 1 has a confounding variable related to the fuel mixtures. Varying the fuel mixture could skew the results of the study and should be kept constant.c. Experiment 2 has a confounding variable related to the type of experiment. A double-blind experiment may increase the risk of the placebo effect and possibly skew the results.d. Experiment 1 has a confounding variable related to the mass of the rockets. Any variation in mass may cause a discrepancy in the distance traveled.e. Experiment 2 has a confounding variable related to the subjects used. Choosing a sample of subjects with high blood pressure instead of individuals with different blood pressure levels may confuse the results.
