That is not yet possible. that technology has not yet been invented.
Answer:
5. The 2 features we need to harness the energy from tides are when tides come in and when tides come out.
6. Tidal energy is the most predictable type of renewable energy is because we know the exact locations of the sun and moon all year round.
Correct answer is D.
Explanation:
A) is not correct answer because this type of theory can not become law. Laws are properties that are same in any part of universe. Nebular theory is not correct for every part of universe.
B) is not correct answer because this theory could be replaced if some evidence show that some other theory is more likely to be correct.
C) is not correct answer because the study has been done on other nebulas in our galaxy. There are many nebulas and by obserwing them this theory was developed.
Answer:
Explanation:
Given:
- change in stiffness constant of the spring on replacing the original springs,
- mass of the car,
- initial length of the original car-spring before compression,
- final length of the original car-spring after compression,
So, weight of the car:
<u>Now the spring constant of original spring:</u>
(since 4 springs are in parallel)
<u>So the stiffness constant of the new springs:</u>
<u>Now the height lowered:</u>
(since 4 springs are in parallel)
1 N = 1 kgm/s²
1 N / (1m/s²) = 1 kg
2540 N / (9,8 m/s²) = 259,18 kg
