<span>Since density is equal to mass divided by volume, we can determine the relationship between mass, density, and volume. Therefore, we can automatically know that the answer must either be A or B, since this information is determinable.
The prompt lists the object as small. Therefore, we know that density is high, but volume is low. Let's examine the equation (D = M/V), where d = density, m = mass, and v = volume. In order for any number to be divided by a smaller number and have the end result be a higher number, the numerator (i.e. mass) must be bigger than the denominator (i.e. volume).
We can also see that this is true by substituting in somewhat random numbers for d, m, and v.
D = M / V
5 = 10 / 2
10 > 2
M > V
In conclusion, your answer is D.</span>
The speed during the first hour is the slope of the piece of line that shows the first hour on the graph.
Average speed is always=(distance covered)/(time to cover the distance)
Distance covered during the first hour = from 0 miles to 40 miles on the graph; that's 40 miles.
Time to cover the distance = from 0 hours to 1 hour on the graph; that's 1 hour
Average speed = (40 miles) / (1 hour)
Average speed during the first hour = 40 miles/hour
I love you too.
Answer: I think I have the answer to your problem!!
A pot of boiling water is a nice everyday example to explain internal energy, heat, and work. However, it's not a good choice for applying the first law of thermodynamics, because the boiling pot isn't a closed system.
Explanation:
Have a great day and don't forget to rate!!!! and give brainlist!
(A) A device that converts heat into work with 100% efficiency
It clearly violates the second law of thermodynamics because it warns that while all work can be turned into heat, not all heat can be turned into work. Therefore, despite the innumerable efforts, the efficiencies of the bodies have only been able to reach 60% at present.
The temperature will be the pressure of 130 ka
