Answer:
Tonga is absolutely gorgeous in my opinion, and everyone should find the time to travel there at some point in their lifetime.
Explanation:
Let's look at the option:
A. Only wealthy nations need to repay their debts, so it slows their
progress.
-this is not true, as not only wealthy nations need to pay back debt, but all nations
B. This is no longer a problem because debt repayment was
completely erased after World War II.
-this is not true: this is still a problem, and quite a big one.
C. Both measures rob a developing
nation of money it could use to invest in social welfare improvements.
Well, debt repayment does rob developing nation of money that it could use for other purposes: so it's true! (structural adjustment doesn't rob but it maintains the state in which the nation needs to pay back the debt)- this is the correct answer!
D. They always penalize highly developed nations rather than
underdeveloped ones.
- This is not true, as both countries are penalized, and the underdeveloped ones even more so.
Answer:
Explanation:
For a satellite in orbit around a planet, the gravitational force between the planet and the satellite is equal to the centripetal force that keeps the satellite in circular motion.
So, we can write:
where
G is the gravitational constant
M is the mass of the planet
m is the mass of the satellite
r is the orbital radius of the satellite
v is the speed of the satellite
The equation can be rewritten as
Also, we can write the orbital speed as the ratio between the length of the orbit (circumference of the orbit) and orbital period, T:
Substituting into the equation for M,
Here we have:
is the orbital radius
is the orbital period
Substituting, we find the mass of the Saturn:
Answer:
Conservation
Explanation:
One important way to increase non-renewable resources is by conserving them.
- Non-renewable resources are resources which cannot be replenished at the current rate of their usage.
- In short, they become depleted with with usage
- When resources are conserved, they are strategically used.
- This ensures that time is given for them get replenished in the ecosystem.
Examples of non-renewable resources that must be conserved are metallic ores and fossil fuels.
Also, it must be noted that when resources are recycled, it reduces the dependence on the natural resources.
