n = (2.4 x 10^24 atoms) x ((1 mol)/(6.02 x 10^23 atoms)) = 4.0 mol
A particle moves along the curve y = 4x2 + 1 in such a way that the x value is increasing at the rate of 2 units per second. At what rate is y changing when x = 1?.
By differentiating both sides of y = 4x² + 1 with respect to time t, we have
dy/dt = 8x dx/dt
If the x value changes at a rate of +2 units/second (that is, dx/dt = 2) at the moment x = 1, then the y value changes at a rate of
dy/dt = 8 • 1 • 2 units/s = 16 units/s

What are the equations of the asymptotes of the hyperbola? (y+4)236−(x−6)249=1 enter your answer in point-slope form by filling in the boxes. Enter the slope as a simplified fraction.
The point slope form of the asymptote of the hyperbola is; y - 4 = ±(6/7)(x - 6)
We are given the equation of the hyperbola as;[(y + 4)²/36] - [(x - 6)²/49] = 1
We can rewrite this equation as;[(y + 1)²/6²] - [(x - 6)²/7²] = 1
The general equation form of hyperbola is;[(y - k)²/a²] - [(x - h)²/b²] = 1
Comparing this general form to our given equation we can see that;k = -4
h = 6
a = 6
b = 7
Now the equation of the asymptote of a hyperbola follows the general formula;y = ±[a(x - h)/b] + k
Plugging in the relevant values gives us;y = ±(6/7)(x - 6) - 4
>> y - 4 = ±(6/7)(x - 6)

Even at moderate temperatures, attractions between molecules seem to have little effect on the elasticity of gas-gas collisions because.
Attractions have little effect on the elasticity of gas-gas collisions because they are brief and fast. These particle collisions exhibit insufficient time to significantly affect the entire system.
The Kinetic Molecular Theory (KMT) is a model used in order to describe the behavior of gases by understanding the behavior of an ideal gas.
According to this theory, collisions between particles of gases are elastic, and therefore the kinetic energy is conserved when they collide.
An elastic collision can be defined as a type of collision between two particles in which the total kinetic energy remains the same.

Answer:
Their StrengthExplanation:
Where's the choices my answer is their Strength I thinkWhat change in a population would you expect to see if a selection pressure was against the trait of a dominant allele in that population?.
Answer:
The change in population in the given condition would be an increase of true recessive traits in the population and there would be only a few individuals with dominant traits.
In case of selection pressure was against the dominant trait, then individuals of the population who have true recessive alleles would have an advantage over the heterozygous and dominant individuals of the population.
There would be very few individuals carrying its dominant genotype and it may eventually be extinct, however, it would be still dominant. The recessive trait would just become more prominent rather than becoming dominant.
Thus, the number of recessive traits would increase in population, and the number of dominant decrease to numbers.

It takes 87 j of work to stretch an ideal spring, initially 1. 4 m from equilibrium, to a position 2. 9 m from equilibrium. What is the value of the spring constant (force constant) of this spring?.
The spring undergoes a change in potential energy of
1/2 k (2.9 m)² - 1/2 k (1.4 m)² = 87 J
Solve for k :
k ((2.9 m)² - (1.4 m)²) = 174 J
k = (174 J) / ((2.9 m)² - (1.4 m)²)
k ≈ 27 N/m

4. Hurricane.
Explanation:
All of the above-mentioned events happen in chronological order for the hurricane-force winds to occur.
1. Tropical disturbance occurs from the tropics and the subtropics. These are generally 100-300 miles in diameter. It is a tropical weather system of organized conventions. This is the first stage that consists of a loosely organized low-pressure area.
2. Tropical depression is a more organized deep convention and has a closed circulation of sustained winds of less than 39 mph.
3. Tropical storm is the third stage that has sustained winds between 39 - 73 mph.
4. The hurricane is created when the sustained winds finally reach or cross the speed of 74 mph.
