above the exposed mantle (density of 4.1 g/cm^3). Assuming that this"
Answers
Answer:
3433.4m
Explanation:
Volume_submerged = (Density_mantle / Density_mountain) * Volume_exposed
Volume_submerged_meters = Volume_submerged / 1000000
Weight_submerged = Density_mantle * Volume_submerged_meters * g
Weight_submerged = Weight_exposed
Density_mantle * Volume_submerged_meters * g = Density_mountain * Volume_exposed * g
Volume_submerged_meters = (Density_mountain / Density_mantle) * Volume_exposed
Volume_submerged_meters = (3.2 g/cm^3 / 4.1 g/cm^3) * 4400 meters
Volume_submerged_meters = (0.7805) * 4400 meters
Therefore, the total height of the mountain is 3433.4 meters.

Calculate the angle of incidence of the ray on the flat surface of the block
Answers
Answer:
The angle of incidence is 39 degrees
Explanation:
We would apply Snell's law which states that the ratio of the angle of incidence to the sine of the angle of refraction is constant. It is expressed as
n1Sinθ1 = n2Sinθ2
Sinθ1/Sinθ2 = n2/n1
where
θ1 is the angle of incidence
θ2 is the angle of refraction
n1 is the refractive index of air
n2 is the refractive index of glass
From the information given,
n1 = 1.6
θ2 = 90
n2 = 1
Thus,
1.6 x Sinθ1 = 1 x Sin90
Sinθ1 = 1Sin90/1.6 = 0.625
θ1 = Sin^-1(0.625)
θ1 = 39 degrees

Answers
Therefore, the super happy ball will take 32 bounces and travel the distance of less than 1 foot.
First bounce = 13 / 14 × 10 = 130 /14
using geometric progression where the common ratio = 13/14, the first bound = 130/14
ar^n-1 < 1
substitute the values into the equation
130 /14 × 13/14^(n-1) < 1
(13/14)^n-1 < 1÷ (130/14)
(13/14)^n-1 < 14 / 130
take log of both side
log (13 /14)^n-1 < log ( 14/130)
n-1 log (13 /14) < log ( 14/130)
since log (13/14) negative
n-1 > (log( 14/130)) ÷ ( log (13/14)
n - 1 > 30.07

force, weight: what is the weight of a person on the moon (look up g for the moon in m/s2) if the mass of the person on the earth is 105 lbm? remember to first convert from lbm to kg.
Answers
The weight of a person on the moon given that the mass of the person on Earth is 105 lbm is 17.3 lbf.
Force is defined as the influence that produces a change in motion of an object. The unit of force is newton (N), which is defined as the amount of force that can accelerate a mass of 1 kg at a rate of 1 meter per second squared (m/s²).
The weight of an object is the gravitational force acting on the object. It is directly proportional to the mass of the object and the acceleration due to gravity. The unit of weight is newton (N).
Formula to calculate weight:
Weight (N) = mass (kg) × acceleration due to gravity (m/s²)
Conversion from lbm to kg:1 lbm = 0.453592 kg
Acceleration due to gravity on the moon is 1.622 m/s².
Therefore, Weight (N) = mass (kg) × acceleration due to gravity (m/s²)
Weight on Earth = 105 lbm
= 47.63 kg
Weight on Moon = 47.63 × 1.622
Weight on Moon = 77.19 N
= 17.3 lbf
Therefore, the weight of a person on the moon given that the mass of the person on Earth is 105 lbm is 17.3 lbf.

1. A 5 kg block is pulled across a table by a horizontal force of 40 N with a frictional force of 8 N
opposing the motion. Calculate the acceleration of the object.
Answers
The acceleration of the block is 6.4 m/s².
To calculate the acceleration of the block, we need to consider the forces acting on it.
The applied force is 40 N, and since it is the only horizontal force in the direction of motion, it is the net force acting on the block.
The frictional force opposing the motion is 8 N.
The acceleration, we can use Newton's second law, which states that the net force acting on an object is equal to its mass multiplied by its acceleration (F = ma).
The net force is the difference between the applied force and the frictional force:
40 N - 8 N = 32 N.
Now, we can plug the values into Newton's second law:
32 N = 5 kg × a.
Solving for the acceleration (a), we get
a = 32 N / 5 kg
a = 6.4 m/s².
Therefore, the acceleration of the block is 6.4 m/s².

if the power of a speaker is doubled and the area through which the sound is emitted is also doubled, does the intensity of the sound increase, decrease, or stay the same?
Answers
The intensity of the sound would stay the same when both the power and the emitting area are doubled.
The intensity of sound is determined by the power of the source and the area over which the sound is spread. Intensity is calculated by dividing the power by the area. In this case, if the power of the speaker is doubled and the area through which the sound is emitted is also doubled, the intensity of the sound would stay the same. Doubling the power would increase the numerator of the intensity equation, but doubling the area would increase the denominator by the same factor, resulting in a cancellation effect. As a result, the intensity of the sound remains unchanged.

Answers
By ideal gas approximation, the final pressure is 75.76 atm.
We need to know about the ideal gas theory to solve this problem. The ideal gas is assumed that there is no interaction between particles in a gas. It can be determined by the equation
P . V = n . R . T
where P is pressure, V is volume, n is the number of moles gas, R is the ideal gas constant (8.31 J/mol.K) and T is temperature.
From the question above, we know that
P1 = 50 atm
T1 = 330 K
T2 = 500 K
When the initial and final volume is the same, we can use the ratio of pressure and temperature as
P1 / P2 = T1 / T2

Answers
The number of poles in the right half-plane is 1, the number of poles in the left half-plane is 2, and the number of poles on the j omega-axis is 1.
To construct the Routh table, we first need to write the characteristic equation of the transfer function T(s) in the following form:
s^5 - s^4 + 3s^3 - 3s^2 + 3s - 2 + 8/s = 0
The Routh table has the following form:
s^5 coefficient: 1 3 3
s^4 coefficient: -1 -3 8/3
s^3 coefficient: 2 2
s^2 coefficient: -2 -8/3
s^1 coefficient: 1
s^0 coefficient: -2/3
To determine the number of poles in the right half-plane, we need to count the number of sign changes in the first column of the Routh table. In this case, there is only one sign change, so there is only one pole in the right half-plane.
To determine the number of poles in the left half-plane, we need to count the number of sign changes in the first column of the Routh table, starting from the top row and moving downwards. In this case, there are two sign changes, so there are two poles in the left half-plane.
To determine the number of poles on the j omega-axis, we need to count the number of rows in the Routh table that has a zero in the first column. In this case, there is one row with a zero in the first column, so there is one pole on the j omega-axis.

What happens when a proton is placed directly in the path of the proton cannon?
Answers
Answer:
Proton is positively charged and is thus, attracted to the negative plate. Hence, it will take the path D after leaving the region between the charged plates.When a proton is placed directly in the path of the proton cannon, it will experience a strong electromagnetic force. The proton cannon emits a beam of protons at high energy and velocity. When the proton in the path of the cannon interacts with the beam, there will be a collision between the two protons.
During the collision, the protons may undergo a process called scattering, where they change direction and momentum. The exact outcome of the collision depends on the energy and angle of the incoming proton, as well as the properties of the target proton. It is possible that the protons may scatter off each other, transferring energy and momentum in the process.
In some cases, the collision may result in the absorption of the incoming proton by the target proton. This can lead to the formation of a more massive particle or the emission of other particles. The specifics of the interaction will depend on the energy and conditions of the proton cannon and the characteristics of the protons involved.
Overall, placing a proton directly in the path of a proton cannon will result in a collision and potential scattering or absorption of the protons, causing changes in their momentum and possibly leading to the creation of other particles.
