Two identical stones are simultaneously launched horizontally from two slingshots at
the same height. Stone A is launched with an initial speed of 5 m/s. Stone B is
launched with an initial speed of 1 m/s. Which stone hits the ground first, and where
do they land?)
Answers
Answer:
a) Both stones hit at the same time, b) Stones A and B will land at a distance of \(2.26\sqrt{y_{o}}\) and \(0.452\sqrt{y_{o}}\) meters, respectively.
Explanation:
Each stone experiments a parabolic motion, that is, the combination of a horizontal motion at constant velocity and a vertical uniform accelerated motion due to gravity. We know that each stone is launched horizontally at the same height and from the same initial position.
The equations of motion for each stone are described below:
Stone A
\(x_{A} = x_{o} + v_{A,o}\cdot t_{A}\)
\(0 = y_{o} + \frac{1}{2}\cdot g\cdot t_{A}^{2}\)
Stone B
\(x_{B} = x_{o} + v_{B,o}\cdot t_{B}\)
\(0 = y_{o} + \frac{1}{2}\cdot g\cdot t_{B}^{2}\)
a) Which stone hits the ground first?
The stone that hits the ground first has the lowest time. If we know that \(v_{A,o} = 5\,\frac{m}{s}\), \(v_{B,o} = 1\,\frac{m}{s}\), \(x_{o} = 0\,m\) and \(g = -9.807\,\frac{m}{s^{2}}\), then the equations of motion are reduced into this:
Stone A
\(x_{A} = 5\cdot t_{A}\) (Eq. 1)
\(y_{o} -4.905\cdot t_{A}^{2}= 0\) (Eq. 2)
Stone B
\(x_{B} = t_{B}\) (Eq. 3)
\(y_{o} -4.905\cdot t_{B}^{2}= 0\) (Eq. 4)
From (Eq. 2) and (Eq. 4), we get that \(t_{A} = t_{B}\).
Both stones hit at the same time.
b) Where do they land?
From (Eq. 2) and (Eq. 4), we get:
\(y_{o} = 4.905\cdot t^{2}\)
The time is cleared within the expression:
\(t =\sqrt{\frac{y_{o}}{4.905} }\)
\(t \approx 0.452\sqrt{y_{o}}\)
And from (Eq. 1) and (Eq. 3), we get the following equations of motion:
\(x_{A}= 5\cdot t\)
\(x_{B} = t\)
The horizontal distance taken by each stone is calculated by direct substitution on each expression:
\(x_{A} = 2.26\sqrt{y_{o}}\,m\)
\(x_{B} = 0.452\sqrt{y_{o}}\,m\)
Stones A and B will land at a distance of \(2.26\sqrt{y_{o}}\) and \(0.452\sqrt{y_{o}}\) meters, respectively.

A hanging wire made of an alloy of magnesium with diameter 0.08 cm is initially 2.0 m long. When a 12 kg mass is hung from it, the wire stretches an amount 1.17 cm. A mole of magnesium has a mass of 24 grams, and its density is 1.74 g/cm3.Based on these experimental measurements, what is Young's modulus for this alloy of magnesium
Answers
The Young's modulus for the alloy of magnesium is approximately 1.01 × 10^10 N/m².
What is the value of Young's modulus for this alloy of magnesium?Young's modulus is a measure of the stiffness of a material and represents its ability to resist deformation under stress.
To calculate Young's modulus for the given alloy of magnesium, we need to use Hooke's Law, which states that the stress applied to a material is directly proportional to the strain it produces.
First, we calculate the strain of the wire using the formula:
\(strain = change\ in\ length / original\ length\)
In this case, the wire stretches by 1.17 cm, so the change in length is 0.0117 m. The original length of the wire is 2.0 m.
Next, we calculate the stress applied to the wire using the formula:
\(stress = force / cross-sectional\ area.\)
The force applied to the wire is the weight of the 12 kg mass, which is 12
kg × 9.8 m/s² = 117.6 N.
The cross-sectional area of the wire is given by the formula:
\(cross-sectional\ area = \pi * (diameter/2)\²\)
Substituting the values, we find the cross-sectional area to be approximately 5.03 × 10^(-6) m².
Now, we can calculate Young's modulus using the formula:
\(Young's\ modulus = stress / strain\)
Substituting the values, we get
\(Young's modulus = 117.6 N / (5.03 * 10 \^\ (-6) m\² / 0.0117 m) \\= 1.01 * 10^10 N/m\²\)
Therefore, the approximate value of Young's modulus for the alloy of magnesium is 1.01 × 10^10 N/m².

how can you account for the differences in the entropies of combination of methyl propane (-1465J/mol K) and butane (1465J/mol K)
Answers
Explanation:
The change in entropy is a measure of temperature. When the temperature of a compound or a system increases, there will be more randomness in the system.
The boiling point is directly related to the number of carbon atoms but is indirectly proportional to the branching in a hydrocarbon.
Butane and methyl propane, both have 4 carbon atoms.
But, butane has 4 carbon atoms in a straight chain while methyl propane has 3 carbon atoms in a straight chain and 1 methyl substituent which makes it a branched hydrocarbon.
Thus, the boiling point of methyl propane will be less than the butane. Likewise, the pattern in entropies will be seen.
When two horizonta forces are exerted on a cart, 600N forward and 400N backward, the cart undergoes acceleration. What additional force is needed to produce nonaccelerated motion?
Answers
To produce non-accelerated motion, an additional force of 200N is needed, exerted in the backward direction to balance the net force (600N - 400N = 200N).
When two horizontal forces are exerted on a cart, 600N forward and 400N backward, the cart undergoes acceleration. To produce nonaccelerated motion, the additional force needed would be equal and opposite to the net force acting on the cart. In this case, the net force is 200N forward (600N forward - 400N backward), so an additional force of 200N backward would be needed to produce nonaccelerated motion.

Light of wavelength 580 nm in incident on a diffraction grating. A screen is placed 2.5 m away, and the distance between the zero order and first order diffraction spots is 35 cm on the screen. How many lines per mm are etched on the diffraction grating
Answers
The diffraction grating of the light of wavelength 580 nm and a screen is placed 2.5 m away, and the distance between the zero order and first order diffraction spots is 35 cm has 31.5 lines per mm etched on it.
The formula to use in this case is:
d sin θ = mλ
Where d is the distance between adjacent lines on the diffraction grating, θ is the angle between the incident light and the diffracted light, m is the order of the diffraction (0 for the zero order, 1 for the first order, etc.), and λ is the wavelength of the incident light.
In this case, we are given λ = 580 nm, m = 1, d is the unknown we are looking for, and θ can be calculated from the geometry of the setup:
tan θ = opposite / adjacent
= (35 cm / 2) / 2.5 m
= 0.07
θ = arctan(0.07)
= 4 degrees
Now we can rearrange the formula to solve for d:
d = mλ / sin θ
= (1)(580 nm) / sin(4 degrees)
= 0.0317 mm
Finally, we can convert this to lines per mm by taking the reciprocal:
lines per mm = 1 / d

Answers
Lamarck's theory of evolution, also known as Lamarckism, proposed two main ideas. Firstly, the theory of use and disuse suggests that organs or traits that are used more frequently become stronger and more developed, while those that are not used gradually deteriorate over generations. Secondly, the theory of inheritance of acquired characteristics states that an organism can pass on traits acquired during its lifetime to its offspring.
Under Lamarck's theory, an organism might evolve by developing or strengthening certain traits through use and passing them on to the next generation. For example, if a giraffe stretches its neck to reach leaves high in the trees, its offspring would inherit a longer neck. This gradual elongation of the neck would continue over generations.
In contrast, under Darwin's theory of natural selection, an organism might evolve through the process of adaptation to its environment. For instance, consider a bird population with varying beak sizes. If the available food source consists of small seeds, individuals with smaller beaks are more likely to survive and reproduce, passing on their genes for smaller beaks. Over time, the average beak size in the population would decrease due to the selective advantage of smaller beaks in obtaining food.
In summary, Lamarck's theory proposed that acquired traits can be inherited, leading to gradual changes in an organism's characteristics. Darwin's theory, on the other hand, emphasized the role of natural selection in the adaptation of organisms to their environment, resulting in the accumulation of advantageous traits over generations.

A car is initially driving 20 m/s due East. The driver makes a left turn. After completing the turn, the car is moving 21 m/s due North. If this turn takes five seconds to complete, what is the magnitude of the average acceleration of the car during the turn
Answers
The magnitude of the average acceleration of the car during the turn is approximately 5.8 m/s².
To find the magnitude of the average acceleration of the car during the turn, we can use the formula for average acceleration:
Average acceleration (a_avg) = (Change in velocity) / (Change in time)
Given:
Initial velocity (v_i) = 20 m/s due East
Final velocity (v_f) = 21 m/s due North
Time taken (Δt) = 5 seconds
To calculate the change in velocity, we can use vector subtraction:
Change in velocity (Δv) = v_f - v_i
Since the velocities are in different directions, we need to consider their vector components. Let's break down the velocities into their x and y components:
v_i = 20 m/s due East
v_f = 21 m/s due North
The x-component of v_i is 20 m/s and the y-component is 0 m/s.
The x-component of v_f is 0 m/s and the y-component is 21 m/s.
Now, we can calculate the change in velocity:
Δv = (Δv_x, Δv_y) = (0 m/s - 20 m/s, 21 m/s - 0 m/s)
= (-20 m/s, 21 m/s)
The change in time (Δt) is given as 5 seconds.
To calculate the average acceleration:
a_avg = Δv / Δt
= (-20 m/s, 21 m/s) / 5 s
= (-4 m/s², 4.2 m/s²)
To find the magnitude of the average acceleration, we take the square root of the sum of the squares of the components:
|a_avg| = √((-4 m/s²)² + (4.2 m/s²)²)
≈ √(16 m²/s⁴ + 17.64 m²/s⁴)
≈ √(33.64 m²/s⁴)
