Answer:
Molybdenum and seaborgium
Answer:
Time to pass the train=0.05 h
How far the car traveled in this time=4.75 Km
Explanation:
We have that the train and the car are moving in the same direction, the difference between the speed of the vehicles is:
We will use this difference in the speed of the car an train to calculate how much time take the car to pass the train. For this we have that the train is 1km long and the car is moving with a speed of 20km/h (we use this value because is the speed that the car have in advantage of the train) then for a movement with a constant speed we have:
Where x is the distance, t is the time and v is the speed. using the data that we have:
This is the time that the car take to pass the train. Now to calculate how far the car have traveled in this time we have to considered the speed of 95Km/h of the car, then:
Explanation:
Johannes Kepler, working with the data carefully collected by Tycho Brahe without the help of a telescope, especially those related to the retrograde motion of Mars, realized that the motion of the planets could not be explained by his model of perfect polyhedra. Coming to the conclusion that all the planets move in elliptical orbits, with the Sun in one of the foci.
A) This process is only in the research phase.
Explanation:
The process of nuclear fusion is only the research phase.
In nuclear fusion, light atoms combines to form heavier ones with the release of huge amount of energy. Nuclear fusion which is the splitting of heavy unstable nuclides into stable ones also release a large amount of energy.
- Nuclear fission requires a very high activation energy to start with.
- The energy barrier need to start the reaction is very high.
- It occurs at high temperatures and pressure.
- This is not a feasible processes and it is still at its research phase.
- The process occurs naturally in the core of stars
