A slender missile is flying at Mach 1.5 at low altitude. Assume the wave generated by the nose of the missile is a Mach wave. This wave intersects the ground 559 ft behind the nose. At what altitude is the missile flying
Answers
The missile is flying at an altitude of approximately 124.22 ft above the ground.
The altitude at which the missile is flying, we need to calculate the distance between the ground and the Mach wave generated by the nose of the missile.
Let's assume that the speed of sound at the given altitude is 1116 ft/s (which is approximately the speed of sound at sea level).
The formula to calculate the distance between the ground and the Mach wave is:
\(\(d = \frac{M^2}{\sqrt{M^2 - 1}} \cdot h\)\)
Where:
\(\(d\)\) = Distance between the ground and the Mach wave
\(\(M\)\)= Mach number of the missile
\(\(h\)\) = Altitude of the missile above the ground
In this case, the Mach number of the missile is 1.5, and the distance between the ground and the Mach wave \(\(d\)\) is given as 559 ft. Let's substitute these values into the formula and solve for\(\(h\)\):
\(\(559 = \frac{1.5^2}{\sqrt{1.5^2 - 1}} \cdot h\)\)
\(\(559 = \frac{2.25}{\sqrt{2.25 - 1}} \cdot h\)\)
\(\(559 = \frac{2.25}{\sqrt{0.25}} \cdot h\)\)
\(\(559 = \frac{2.25}{0.5} \cdot h\)\)\(\(559 = \frac{2.25}{\sqrt{2.25 - 1}} \cdot h\)\)
\(\(559 = 4.5 \cdot h\)\)
Now, we can solve for \(\(h\)\):
\(\(h = \frac{559}{4.5}\)\)
\(\(h \approx 124.22\) ft\)

what is the quantiti of component k that will be needed to assemble 30 units of p
Answers
Since we need to assemble 30 units of p, the total amount of component k required would be (x/2) * 30 units.
To determine the quantity of component k that will be needed to assemble 30 units of p, we need to have the required amount of component k for one unit of p.
The required amount of component k can be obtained from the given data.
A component k is required in a ratio of 2:1 with component j to produce one unit of p. This means that for every two units of component j, one unit of component k is required.
So, to find the required quantity of component k for one unit of p, we need to divide the amount of component k required for 2 units of component j by 2.
Let's assume that x units of component j are required for one unit of p. Then, the required amount of component k for one unit of p would be x/2 units.
Since component j is required in a ratio of 3:1 with component i, we can assume that y units of component i are required for one unit of p.
Then, the required amount of component j for one unit of p would be 3y units.
Therefore, the total amount of component k required for one unit of p can be expressed as (x/2) units. The total amount of component j required for one unit of p can be expressed as 3y units.

(ii) Sea walls (also know as "hard defences") are an engineering option preferred by some coastal human communities. What are the potential impacts on neighbouring communities of sea walls?
Answers
The two main mechanisms involved in sea level rise are thermal expansion and the melting of land-based ice. Hard defenses can provide protection against rising sea levels and coastal erosion for the communities located directly behind them, they can have potential impacts on neighboring communities.
As the Earth's oceans absorb heat from the atmosphere, the water expands thermally, leading to an increase in sea level.
Melting of land-based ice refers to the melting of glaciers and ice sheets, such as those in Greenland and Antarctica.
Under the RCP8.5 scenario, which represents a high greenhouse gas emissions trajectory, the dominant mechanism of sea level rise is expected to be the melting of land-based ice.
The increased temperature and subsequent accelerated melting of ice sheets and glaciers would contribute significantly to rising sea levels.
Hard defenses can provide protection against rising sea levels and coastal erosion for the communities located directly behind them, they can have potential impacts on neighboring communities.
Some of these impacts include Increased erosion, altered wave patterns, loss of coastal access, coastal squeeze, and visual and aesthetic impact.

What is Momentum ?Momentum is the product of mass and velocity. It is a vector quantity. And it is measured in Kgm/s
If two vehicles have a head-on collision, the vehicles essentially stick together and travel a certain distance for 20 seconds before coming to a complete stop. The final velocity for both vehicles immediately after the crash can be obtain by using the formula
v = u - at
Where
v = final velocityu = initial velocitya = accelerationt = timeIf you are able to obtain the mass of both vehicles, the initial velocity for Vehicle A, and the final velocity for both vehicles immediately after the crash, then you can determine the momentum of both vehicles before the collision by calculating the momentum of both after the collision because momentum is always conserved.
Or by first calculating the initial velocity for vehicle B by using the formula below
\(M_{1}U_{1} - M_{2}U_{2} = (M_{1} + M_{2} )V\)
where
M1 = mass of the first objectU1 = initial velocity of the first objectM2 = mass of the second objectU2 = initial velocity of the second objectV = common final velocityAfter we obtain initial velocity for vehicle B, we can calculate the momentum of both vehicles before the collision

Answers
By assuming that enthalpy and entropy do not vary with temperature, the reaction will be at equilibrium at a temperature of approximately 330 K.
The temperature at which the reaction will be at equilibrium can be determined using the Gibbs free energy equation: ΔG = ΔH - TΔS.
At equilibrium, ΔG = 0. So, we can set up the equation as follows:
0 = -32,000 J/mol - T(-98 J/mol*K)
Now, we need to solve T:
32,000 J/mol = 98 J/mol*K * T
T = 32,000 J/mol / 98 J/mol*K
T = 326.53 K
Therefore, the temperature at which the reaction will be at equilibrium is approximately 326.53 K. The closest answer choice to 326.53 K is B. 330 K.

Increasing the mass of the puck decreases its speed, while decreasing the mass increases its speed. This change is explained by the principle of conservation of momentum.
Explanation:When the mass of a puck is increased, its speed decreases, and when the mass is decreased, the speed increases. This is known as the principle of conservation of momentum, which states that the total momentum of a system remains constant when there is no external force acting on it. The momentum of an object is the product of its mass and velocity, so when the mass of the puck is increased, the momentum decreases, resulting in a decrease in speed.

A particle possessing 6.25 ?C of charge and mass 6.55 g is fired at a speed of 459 cm/s through two charged plates of length 34.6 cm, as shown in the figure. If the electric field is constant at 2060 N/C between the two plates* and directed upwards, calculate the distance y in which the charge falls below its intended path.
Which field strength will allow the particle to pass between the plates along a straight path.
Answers
Coulomb's law states that the force of attraction or repulsion between two charged particles is directly proportional to the product of their charges and inversely proportional to the square of the distance between them.
Given, Charge
q = 6.25 × 10⁻⁶ C and mass
m = 6.55 g = 6.55 × 10⁻³ kg
Speed of the particle = v = 459 cm/s = 4.59 m/s
Length of the plates,
d = 34.6 cm = 0.346 m
Electric field strength,
E = 2060 N/C
Mathematically,
F ∝ Q₁Q₂/d²
The force on the charge q due to the electric field E is given by
F = Eq
Distance fallen by the particle is given
by = 1/2 gt²,
where g = acceleration due to gravity = 9.8 m/s²In the vertical direction, force on the charge F = mg
Since the charge falls below its intended path, the vertical component of the electric force is greater than the force due to gravity.
So,
we have
F = Eq = mg ⇒ qE = mg
⇒ y = 1/2 gt² = (qE/m) × (t²/2) = (qE/m) × [2y/g]²/2
⇒ y = [(qE/m) × (y/g)]²
⇒ y = (qE/mg)²/3 [∵ t = 2y/g]
Substituting the given values,
we gety = [(6.25 × 10⁻⁶ C × 2060 N/C) / (6.55 × 10⁻³ kg × 9.8 m/s²)]²/3= (1.233 × 10⁻²)²/3= 1.59 × 10⁻⁴ m = 1.59 × 10⁻² cm
Hence, the particle falls 1.59 × 10⁻² cm below its intended path.
Therefore, a field strength of 1.04 × 10⁴ N/C would allow the particle to pass through the plates along a straight path.

Answers
Miguel will burn an additional 750 kilocalories each week with this exercise regime. It's worth noting that in order to lose weight.
We first need to convert Miguel's weight from pounds to kilograms. One pound is equal to 0.453592 kilograms, so Miguel's weight is approximately 113.4 kilograms.
Next, we can calculate how many kilocalories Miguel will burn per minute by multiplying his weight in kilograms by the rate of calorie burn per minute:
0.044 kcal/kg body weight/minute * 113.4 kg = 5.0 kcal/minute
Miguel walks for 30 minutes, five days a week, so he will burn an additional:
5.0 kcal/minute * 30 minutes * 5 days = 750 kilocalories per week
Therefore, Miguel will burn an additional 750 kilocalories each week with this exercise regime. It's worth noting that in order to lose weight, Miguel will need to ensure that he is also consuming fewer kilocalories than he is burning overall, not just through exercise.
