If the Sun were replaced by a 1-solar-mass black hole, then Earth wouldcontinue to orbit the black hole in precisely its present orbit. The planets would actually continue on in their orbits as if nothing had happened<span>.</span>
Answer:
20 m/s
Explanation:
The frictional force the road exerts on the car provides the centripetal force that keeps the car in circular motion along the curve:
where
F is the centripetal force
m is the mass of the car
r is the radius of the curve
v is the speed of the car
In this problem we have:
m = 2000 kg
r = 200 m
F = 4000 N is the maximum force
Re-arranging the equation, we can calculate the maximum speed v corresponding to this force:
If the height of the cannon and the ground are the same and in the absence of air resistance, the fact that it is moving horizontally changes nothing from a static problem in which a 45 degree angle gives maximum x-axis displacement.
Answer:
1)FALSE
2)TRUE
3)FALSE
4) FALSE
Explanation:
1) Retrieving an entry at a given position is not slow ( it is done using index number ) hence the answer is FALSE
2) Adding an entry at the end of the list is Fast this is because in using array implementation a new entry is made immediately after the last position and it is done very fast as well. hence the answer is TRUE
3) Retrieving an entry at a given position ( from an ADT list ) that is been implemented using Vector is very fast this is simply because Indexing in vector is done at a fixed time hence the answer is FALSE
4) Adding an entry at the end of the list is slow using vector hence answer is FALSE
So first of all, you might run out of food, which means that there wont be enough to sustain too many animals/people.
Or, you could simply run out of the space to have any more offspring.
One final one is the introduction of a new predator, which would eat the population, making the growth unpredictable.
Hope this helped!!!! :D
