Consider a 8.96 gram copper block of 24.44JK−1 mol−1 constant molar heat capacity at 85∘C placed in 125 g water constant molar heat capacity 75.29JK−1 mol−1at 25∘C. Consider the heat capacities as constant within the temperature range and calculate for each the change in entropy
Answers
Mass of copper block, m = 8.96 g
Constant molar heat capacity of copper, c1 = 24.44 J K⁻¹ mol⁻¹
Initial temperature of copper block, T1 = 85°C
Mass of water, M = 125 g
Constant molar heat capacity of water, c2 = 75.29 J K⁻¹ mol⁻¹
Initial temperature of water, T2 = 25°C
Heat is transferred from the copper block to the water until both reach a common temperature, T. We are to find the change in entropy for each process using the following formula:
Change in entropy, ΔS = Q / T
where Q is the amount of heat transferred and T is the common temperature of the system. Since the process is reversible, we can also write this as:
ΔS = ∫ dQ / T
Change in entropy of copper block:
The amount of heat transferred from the copper block to the water, Q1 = mc1ΔT = (8.96/63.546) × 24.44 × (T - 85) J/K
where ΔT = T - T1 is the change in temperature.
Using the formula for change in entropy:
ΔS1 = Q1 / T = (8.96/63.546) × 24.44 × (T - 85) / T J/K
Change in entropy of water:
The amount of heat transferred from the copper block to the water is the same as the amount of heat gained by the water, Q2. So,
Q2 = -Q1 = -(8.96/63.546) × 24.44 × (T - 85) J
Using the formula for change in entropy:
ΔS2 = Q2 / T = -(8.96/63.546) × 24.44 × (T - 85) / T J/K
Therefore, the change in entropy for the copper block is given by:
ΔS1 = (8.96/63.546) × 24.44 × (T - 85) / T J/K
And the change in entropy for water is given by:
ΔS2 = -(8.96/63.546) × 24.44 × (T - 85) / T J/K

A tennis ball is thrown straight up into the air with an initial velocity of 12.7 m/s. How high does the tennis ball travel?
Answers
Answer:
8.22m
Explanation:
As interpreted from this problem, the angle of launch is 90 degrees as it is thrown straight up. Given an angle launch of 90°, upward initial velocity of 12.7m/s, and initial height of 0m. A much simpler equation can be used to find the maximum height.
\(h_{max} = h_ {0} + \frac{{v_0}^{2} }{2g}\)
this means that the max height is equal to the initial height plus the initial velocity squared divided by 2 times the acceleration of earth's gravity(≈9.8m/s^2 or 10m/s^2 depending on how you fix it).
when substituted into the equation, you should get.
(9.8m/s^2)
hmax = 0 + ((12.7)^2)/(2*9.8)
hmax = 161.29/19.6 ≈ 8.22
hmax = 8.22m

Coastal engineering projects involve the design and construction of structures to manage and protect coastal areas from erosion, floods, and other natural hazards.
In a wave approaching perpendicular to a 500 m long breakwater, the height of the wave on the backside at a distance of 250 m from one of the ends can be estimated using wave transformation principles.
However, the height of the wave at a distance of 60 m from one of the edges along a 60-degree angle with the breakwater requires additional information, such as wave direction and wave transformation equations, to provide an accurate estimate.
For a wave in water that is 15 m deep with a period of 11 s and a height of 1.4 m, the water particle velocity and pressure at a point 0 m ahead of the wave crest and 2 m below the still water level can be calculated using wave theory equations. The horizontal and vertical displacement of the water particle orbit at this point can also be determined using the properties of wave motion and particle orbits.

a block of known mass m is at rest at the base of a ramp. a second identical block of mass m travels at a known, constant velocity v0 , as shown in figure 1. the block that travels at a constant speed collides with and sticks to the first block. both blocks slide up the ramp and travel with an unknown velocity vr at the top of the ramp, as shown in figure 2. all frictional forces are considered to be negligible. which quantity should the student measure, if any, to determine whether the conservation of momentum applies to the two-block system from immediately before the collision to immediately after the blocks have reached the top of the ramp while stuck together? justify your selection. responses the force due to gravity exerted on both blocks as they travel up the ramp, because the force due to gravity does work on the system as it travels up the ramp.
Answers
The velocity of the two-block system at the top of the ramp is half the initial velocity of the second block. However, the force due to gravity exerted on both blocks as they travel up the ramp is not relevant to the conservation of momentum because it is a conservative force that does not affect the total momentum of the system.
Velocity of th two blocks systemThe total momentum of the system before the collision is equal to the momentum of the second block, which is given by:
p = mv0
where m is the mass of each block, and v0 is the initial velocity of the second block.
After the collision, the two blocks move together with an unknown velocity vr. The total momentum of the system after the collision is:
p' = (2m)vr
where 2m is the total mass of the two blocks, and vr is the final velocity of the system.
The conservation of momentum states that the total momentum of an isolated system remains constant, provided no external forces act on it. Therefore, the total momentum of the system before the collision is equal to the total momentum of the system after the collision:
p = p'
Substituting the expressions for p and p' gives:
mv0 = (2m)vr
Simplifying gives:
vr = v0/2

Explanation:
Given:
H = 75 m
Δt = 0.091 s
g =9.81 m/s²
_________
V₀ - ?
Assume that the stool fell freely, then the time of its fall:
H = g·t²/2
t = √ (2·H / g) = √ (2*75 / 9.81) ≈ 3.910 s
The refrigerator was thrown down with initial speed and fell:
t₁ = t - Δt = 3.910 - 0.091 ≈ 3.82 s
Find the initial chip of the refrigerator:
H = V₀·t₁ + g·t₁²/2
V₀·t₁ = H - g·t₁²/2
V₀ =H / t₁ - g·t₁ / 2
V₀ = 75 / 3.82 - 9.81·3.82 / 2 ≈ 0.90 m/s
So, at first, the stool is simply released from the hands, and the refrigerator is thrown down with the initial speed 0.90 m/s
An airplane travels for 2.5 hours at an average rate

far the plane travels.
Answers
The plane travels a distance of 325 miles if the airplane travels for 2.5 hours at an average speed of 130 miles per hour. Using the distance formula (d = rt), we can calculate the distance.
To find the distance traveled by the airplane, we can use the distance formula, which is represented as d = rt. In this formula, "d" represents the distance, "r" represents the rate or speed at which the object is traveling, and "t" represents the time taken for the travel.
Given that the airplane travels for 2.5 hours at an average rate of 130 miles per hour, we can substitute these values into the formula. The rate of the airplane is 130 miles per hour, and the time taken is 2.5 hours.
Using the formula, we can calculate the distance traveled as follows:
d = rt
d = 130 mph × 2.5 hours
Multiplying the rate (130 mph) by the time (2.5 hours) gives us:
d = 325 miles
Therefore, the airplane travels a distance of 325 miles during the 2.5 hours of travel at an average rate of 130 miles per hour.

A car is moving North at 65 miles per hour. A person is walking due East on a different road. Determine how fast the person is moving at the moment when the person is 50 miles West and 70 miles South of the car and the distance between the person and the car is increasing at a rate of 55 miles per hour.
Answers
We can use the Pythagorean theorem to find the distance between the person and the car:
d^2 = (50)^2 + (70)^2
d = 85 miles (rounded to the nearest mile)
Let x be the distance between the person and the car at time t. We know that dx/dt = 55 mph (the rate at which the distance between the person and the car is increasing).
At the moment in question, the person and the car form a right triangle with the distance between them as the hypotenuse. The person is moving due East, so their velocity vector is horizontal. We can use the Pythagorean theorem again to find the magnitude of the person's velocity vector:
(65)^2 + (dx/dt)^2 = (60)^2
(dx/dt)^2 = (60)^2 - (65)^2
dx/dt = 48.8 mph (rounded to the nearest tenth)
Therefore, the person is moving at 48.8 mph due East at the moment in question.

Hοrizοntal Cοmpοnent:
The persοn is walking due East, which is perpendicular tο the Nοrth directiοn οf the car. Therefοre, the hοrizοntal cοmpοnent οf the persοn's velοcity dοes nοt affect the speed at which the persοn is mοving away frοm the car.
Vertical Cοmpοnent:
The persοn is 70 miles Sοuth οf the car, and the distance between them is increasing at a rate οf 55 miles per hοur. This indicates that the persοn's vertical pοsitiοn is changing with time. Since the persοn is mοving in the Sοuth directiοn and the distance is increasing, the persοn's speed can be determined by the rate οf change οf the vertical distance.
Given that the distance is increasing at a rate οf 55 miles per hοur, the persοn's speed in the Sοuth directiοn is 55 miles per hοur.
Therefοre, the persοn is mοving at a speed οf 55 miles per hοur in the Sοuth directiοn when the persοn is 50 miles West and 70 miles Sοuth οf the car, and the distance between them is increasing at a rate οf 55 miles per hοur.

Answers
$270,000 amount of sales revenue is needed by Vaughn to break even.
How much sales revenue is needed to break even?To calculate the sales revenue needed to break even, we need to consider the fixed costs and the variable costs per unit.
Fixed costs: $120,000
Variable costs per unit: $50
To break even, the total sales revenue should cover both the fixed costs and the variable costs. The formula to calculate the break-even sales revenue is:
Break-even sales revenue = Fixed costs / (1 - (Variable costs / Sales price per unit))
In this case, the sales price per unit is $90.
Break-even sales revenue = $120,000 / (1 - ($50 / $90))
= $120,000 / (1 - 5/9)
= $120,000 / (4/9)
= $120,000 * (9/4)
= $270,000
