Assuming that the object doesn't rest, and keeps that pace going for three days straight, first you need to calculate the the amount of meters the object can travel in one day. And to find that out you need to find the number of meters it travels per minute, which is 5 times 60, which is 300. Then calculate how far it travels per hour, which is 300 times 60, which is 18,000. Then find out how far it travels in a day, which is 18,000 times 24, which is 432,000. Then to find how many meters it travels in 3 days you multiply 432,000 by 3 which is 1,296,000. Then to find how many kilometers that is, you divide that by 1,000, which comes out to be 1296 kilometers in 3 days.
Answer:
22.47 %
Explanation:
v 1 = 328 m/s, v 2 = 363 m/s
We know that the velocity of a wave in a stretch string is directly proportional to the square root of the tension in the string.
Percentage increase in the tension
= \left ( \frac{1}{0.8165}-1 \right )\times 100
= 22.47 %
Hey!
First, let's write the problem.
Subtract the numbers, we would do the following operation,
Add 2 to both sides.
This tells us that our final answer would be,
Thanks!

Answer:
Explanation:
First of all, we have to calculate the heat released by the steam whem it turns into liquid water. This is given by:
where
is the mass of steam
is the latent heat of vaporization
Substituting,
Now we find the heat absorbed by the ice when it turns into liquid water:
where
is the mass of ice
is the latent heat of fusion
So,
Then, we call:
the heat absorbed by the ice (now liquid water) till reaching the equilibrium temperature T, where
is the specific heat capacity of water
the heat released by the steam (now liquid water) till reaching the equilibrium temperature T
Since the total heat absorbed must be equal to the total heat released, we have:
And now we can solve to find T:
Fossil fuels and natural gases
