Just finished the whole quiz
Idk what my grade is on the written part but the rest are all correct
3. A C D
4. Sputnik
5. A D
6. Radio
7.C
8. False
9. A
10. A
11. False
To determine the correct answers, let's examine each option and see if rockets have been used in those areas:
a. Warfare: Yes, rockets have been used in warfare. They have been historically used as weapons of war, such as in the form of early fire arrows or more advanced guided missiles.
b. Submarine propulsion: No, rockets are not commonly used for submarine propulsion. Submarines typically use nuclear power, diesel-electric engines, or some combination of these technologies for propulsion.
c. Fireworks: Yes, rockets are commonly used for fireworks displays. Firework rockets are designed to travel into the sky and explode, creating dazzling fireworks displays.
d. Jet engines: Rockets are not typically used as jet engines. Jet engines work on the principle of sucking in air and expelling it at high velocity to create thrust. On the other hand, rockets carry their own oxidizer and fuel, allowing them to operate in the vacuum of space.
e. Space exploration: Yes, rockets are extensively used in space exploration. They play a crucial role in launching satellites, crewed missions, and robotic probes into space. Rockets are used to carry spacecraft beyond Earth's atmosphere and into orbit or on interplanetary missions.
Based on the above analysis, the correct answers are:
a. Warfare
c. Fireworks
e. Space exploration
